| |
| : 2. Description of Observation: (continuation) to NUREG 0 5 8 8, Category I req uiremen ts . " NUREG 0538, Category I specifies IEEE 323-1974 requirements and the subject EQ Audit Package indicates compliance with IEEE 323-1974.
| |
| 2.1 There is an apparent failure to meet the licensing requirements of NUREG 0588 for the following reasons :
| |
| : a. Low Voltage Penetrations ^
| |
| : 1) Equipment Evaluation Summary Sheet E-135-PEN-001, fails to identify tag numbers of penetrations qualified by this audit package.
| |
| : 2) NUREG 0588, paragraph 3 (1) states:
| |
| " Quantified margins should be applied to the design parameters discussed in Section 1 to assure that the postulated accident conditions have been enveloped during testing. These margins should be applied in addition to any margins (conservatism) applied during the derivation of the specified plant parameters. "
| |
| Documentation presented in the EQ Audit Package fails to adequately address margin. Qualification is not based upon the LOCA temperature profile plus margin, but rather upon the LOCA temperature profile plus margin minus 25'F. Adequate justification is not provided for reducing the LOCA profile by 25'F. The statement that there is a 25'F gradient from the inboard to outboard end of the penetration, is not acceptable as the inboard end will be exposed to the full LOCA temperature profile.
| |
| : 3) NUREG 05 88, paragraph 3 (1) requires that the qualification testing to envelope the postulated accident conditions plus margin. NUREG 0588 requires testing of 110 days
| |
| | |
| Public Service Electric and Gas Company Project No. 7212-30 Hope Creek Generating Station - Unit 1 Page 3 of 6 OBSEl<VATION REPORT OR No.141, Rev. 0 , Date 6/27/85
| |
| : 2. Description of Observation: (continuation) or a lessor time with justification of conservatism.
| |
| There is an apparent failure to meet this requirement.
| |
| Testing was documented at 30 days , however, no justification (i.e. , use of the n degree rule ,
| |
| Arrhenius equation, etc.) was documented in the report to demonstrate equivalence to 110 day testing.
| |
| Per conversations with PSE&G and BPC (TSB-3SB), credit is not taken for the n degree rule identified in the penetration reports. Therefore, there is no objective evidence demonstrating that the post DBE testing performed envelopes the .HCGS requirements for the Low Voltage Penetrations.
| |
| : b. bdium Voltage Penetrations
| |
| : 1) Concern'2.1.a.2 above also applies to medium v:].tage penetrations.
| |
| : 2) Concern 2.1.a.3 above also applies to medium voltage penetrations.
| |
| : 3) There is no objective evidence demonstrating the evaluation of jet impingement forces per Technical Specification 10855-E-135 (Q) , Rev. 6, dated 1/31/85, for the medium voltage , penetrations.
| |
| : 4) Technical Specification E-135, Section 4, states that "the electric penetration assemblies shall be designed, fabricated, rated, tested and shall perform in accordance with...IEEE 317-1976." There is no objective evidence demonstrating the evaluation of fire resistance per IEEE 317-1976, Section 6.3.1, for the medium voltage penetrations.
| |
| : c. Anaconda Cable NUREG 0 588, Section 2. 3 (1) requires the same piece of equipment be used throughout the test sequence, simulating as close as possible the postulated accident environment.
| |
| There is an apparent failure to meet this requirement as qualification is made using three separate reports with three distinct groups of test specimens. There is no objective evidence presented which adequately justifies the use of dif ferent reports to substantiate the qualification.

| |
| : 2. Description of Observation: (continuation)
| |
| : d. Westinghouse Coaxial Connector Section 8.1 of IEEE 323-1974, requires that the qualification documentation shall verify that each type of equipment is qualified for its application and meets its specified
| |
| < requirements. The EQ Audit Package E135(Q) does not establish similarity between the tested and installed connectors. Therefore, there is no assurance that the connectors tested in Report E135(O)-98-3 qualify the connectors identified in EESS E135-CONN-005.
| |
| 2.2 Information contained in the following " Equipment Evaluation Summary Sheets" is not consistent with data identified in the Material Requisition 10855-E135 (Q) , Rev. 12, dated 3/22/85, FSAR Table 3.,11-5, Vendor Report or Technical Specification 10855-E135(Q), Rev. 6, dated 1/31/85, as noted below: ,
| |
| 'a . Low Voltage Penetrations (EESS No. E-135-PEN-001)
| |
| : 1) The qualified operating time and margin documented in the EESS, do not reflect the actual results of Test Report E135 (Q)-4-6.
| |
| : 2) Pressure margin identified in the EESS is not consistent with Vendor Test Report E135 (Q)-4-6.
| |
| : 3) Model number footnote is incorrect.
| |
| : 4) Function is not identified.
| |
| 51 Location of Low Voltage Penetrations shown as " Torus Wall" is incomplete; "Drywell Wall" should also be noted.
| |
| : b. Raychem Shrink Tubing (EESS No. 13 5-ST-00 3)
| |
| : 1) Reference for relative humidity specified is incorrect.
| |
| : 2) Pressure margin identified in the EESS, does not reflect actual test margin per Test Report E135(Q)-81-2. ;

| "The fcilowing structures, systems, and components of a s nuclear power plant, including their foundations and supports, I are designated as Seismic Category I and should be designed to withstand the effects of the SSc anc remain functional".
| |
| To be in compliance with these requirements the design of Seismic Category I systems and components should be conducted so that either:
| |
| potential seismic interactions with adjacent structures, systems, or components.are precluded.
| |
| or the Category I items must be capable of accomodating potential scismic interactions with adjacent structures, systems, or components without loss of capability to perform their safety functions.
| |
| In accordance with these requirements, Specification C-406, Exhibit 4, detines the minimum clearance requirement between balance of plant Class (i.e.,
| |
| lE control panels / cabinets, and adjacent walls, systems '
| |
| cable tray, conduits, 0 pipe, instrument tray tubing) and components.
| |
| There is an apparent deficiency in addressing potential interactions which may affect Seismic Category I items other than balance of plant Class lE control panels / cabinets.
| |
| BPC has not provided objective evidence on how potential seismic interactions involving Seismic Category I equipment, other than Class lE panels / cabinets, are addressed.

Regulatory Guide 1.120 endorses the requirements specifled in IEEE Standard 484-1975. This standard provides a formula for calculating the maximura hydrogen evolution rate for a battery. The formula used in the 11/9/78 memorandum does not agree with the formula provided in IEEE Standard 484-1975.

Design Criteria 10855-D-2.12, page 7, requires transverse tray support at a maximum 1G'-0" spacing, and longitudinal support at a maximu-24'-0" spacing. (Vertical support is specified as 8'-0" maximums spacing.) These increased spans in the transverse and longitudin.

| |
| l The seismic response spectra provided in Specification 108 5 5-E-03 4 (Q) appears to be the enveloped spectra for the plant.
| |
| The design of trays is based on the natural frequency of the trav with a simple span of 8'-0" and the corresponding acceleratic for appropriate damping values from the above spectra. The inherent assumption in the above approach is that the supports are rigid and no amplification would occur due to the supports.
| |
| However, the supports are flexible since they are designed for peak accelerations of the response spectra in the vertical and transverse directions. Thus, the design of trays does not appear to consider any amplification due to the flexible supports,

| |
| : 2. Description of Observation: (continuation) stresses (pressure plus seismic) is based on a single test of a 24" x 48" duct with a 6 psf sand load on the top and bottom of the duct (equivalent to approximately 2 "g"). The behavior and corresponding adequacy of the duct at higher "g" levels has not been demonstrated.
| |
| b.
| |
| The tests did not take into consideration the shear buckling of the duct due to dead load and seismic loads. Comparison of only the longitudinal stresses is done and shear buchling or tension field effect is not addressed.
| |
| : c. According to Section 5.4 entitled, "Limitati.ons on Use of Test Results" of the " Structural Design of Class I Seismic HVAC Ducts" (referenced in the subject calculation) the testing which formed the basis for the subject calculation is based on width to height ratios of 1 to 2.
| |
| Design Drawing C-0320-0, Rev. 3, Table 1, which gives the appropriate sheet metal gage for certain widths and heights of duct does allow the width to height ratio to exceed 2 which is outside the testing ratio.
| |
| : d. In the criteria entitled, " Structural Design of Class I Seismic HVAC Ducts" Section B.4, seismic stresses in the duct are computed by treating the duct as a beam. These stresses are found to be small based on a rigid "g" acceleration and the calculation concludes, "The beam stresses are very low and not significant and in general can be ignored." However, the following items are not addressed while computing the frequency of the duct:
| |
| : 1) The effect of flexibility of the companion angle joint on the calculation of frequency of the duct is not included. According to the Tennessee Valley l
| |
| Authority (TVA) document " Summary Report for HVAC Ducts Seismic Qualification and Verification /
| |
| Improvement Program," dated June 16, 1979, page 37 Section 8.4, the actual frequency of the duct was found to be .46 times the frequency computed on the basis of moment of inertia according to AISI Code.
| |
| In addition, it should be noted that the tension flange in TVA calculations was assumed to be equal to-the compression flange, while Bechtel calculations assume the full tension flange to be offective. The reduction in frequency for the Bechtel design may be even greater.

| |
| : 2. Description of Observation: (continuation)
| |
| : 2) On page B.8 of the subject criteria, a 50% fixity at supports is assumed for the duct frequency calculations. Since the duct is continuous over several supports, the frequency calculations should
| |
| ~
| |
| be based on continuous span rather than single span.
| |
| Such calculations will indicate that the f und ar. ental frequency of continuous span corresponds to the frequency of a simple span and not a span with 50%
| |
| fixity.
| |
| : 3) On page B.9 of the subject criteria, the beam frequency calculation was based on a span of 8'-0".
| |
| Drawing C-0388-0, Sheet A-5, Rev. 6, Note 3.14, allows a maximum span of duct to equal 10'-0".
| |
| Note 3.8 on Shoot A-3, Rev. 4, allows transverse bracing to be omitted on alternate supports for certain types of supports. The combination of the two notes could permit the span up to 20'-0" ,
| |
| in the transverse direction. ~
| |
| : 4) The weight of insulation and accessories are not included-in the frequency calculations.
| |
| : e. Overall seismic loads are based on a rigid acceleration and therefore, do not consider amplification by a non-rigid support. In addition, in the overall seismic evaluation of the duct, the flexibility of the duct panel was not considered.
| |
| : f. Bechtel's calculations assume that the full tension flange is effective in lieu of determining the effective flange in accordance with the AISI Code. Consideration of the true effective tension flange may reduce the section redulus of of the duct and increase the corresponding bending stress.
| |
| : g. The effect of duct openings was found not to be considered in the subject calculation, nor in the criteria entitled,
| |
| " Structural Design'of Class I Seismic HVAC Ducts."
| |
| : h. The effect of eccentric load application of duct accessories and attachments was found not to be considered in the subject calculation nor in the criteria entitled, " Structural Design of Class ~I Seismic HVAC Ducts".

| : 2. Description of Observation: (continuation)
| |
| : 1) ADS system has four logic channels B, F, H, D, and two trip channels B and D.
| |
| : 2) If the high drywell pressure signal is not present, the ADS safety relief valve will open af ter the high drywell pressure bypass timer and the ADS timer run out.
| |
| : 3) The automatic ADS logic trip system B requires the following ECCS pump running configurations to function:
| |
| RHR pump B or D, or Core Spray pump B or D.
| |
| : 4) The automatic ADS logic trip system D requires the following ECCS pump running configurations to function: RHR pump A or C, or Core Spray pump A or C.
| |
| : 5) Each ADS trip system timer can be reset manually to delay system initiation. If reactor vessel water level is restored by the HPCI system prior to the end of the time delay, ADS initiation will be prevented.
| |
| : 6) The ADS trip system B actuates the A solenoid pilot valve, and the ADS trip system D actuates the b solenoid pilot valve on each ADS valve. Actuation of either solenoid pilot valve causes the ADS valve to open to provide depressurization.
| |
| : 7) Manual initiation bypasses the ADS trip system time delay and all the trip logic.
| |
| : 8) The air accumulators are sized to be capable of opening the valves and holding them open against the maximum drywell pressure of 62 psig. The accumulator capacity is sufficient for each ADS valve to provide tuo actuations against 70% of the maximum dryuell design pressure.
| |
| b) The DITS incorrectly states that the signal for the relief valves to open is based upon signals for (a) high drywell pressure and (b) reactor vessel low water level (Level 3 or Level 1). Actually, Level 3 is not an initiation signal, but a permissive signal only. The re fore , the statomant concerning reactor vessel low water level should read Level 3 and Level 1.
| |
| : 4. Recommendation for Resolution: (continuation) b) Provide an explanation of the design process which incorporates requirements into the DITS and assurance that omissions of requirements in a DIT would not cause design omissions.

| Also, similar commituents are made in the FSAR Section 3.6.1.2.1 for all high energy systems as for example, in Section 3.6.1.2.6.c, for the llPCI Steam Supply Line:
| |
| l "A combination of pipe whip rostraints and separation by distance or intervening structures ensures the availability of essential systems and conponents in the event of a 1:PCI steam supply line break occurring in the drywell, the HPCI pipe chase compartment, or the !!PCI pump compartment. "
| |
| Regulatory Guide 1.46 suggests that:
| |
| "The determination of the nood for pipe whip restraints should consider the potential consequences of postulated breaks at these locations."
| |
| l FSAR eS'ction 1.8.,1.46 roads in part:
| |
| "The critoria set forth in Regulatory Guido 1.46 are design !
| |
| bases for !! CGS."
| |
| Further, FSAR Section 3.6.1 co:mnits to the follouing:
| |
| "Nucicar safety-related systems are designed to ensure that components required for safo shutdown and isolation of the reactor do not fail as a result of a failuro in a high or moderato energy piping system."
| |
| Pipe whip rostraints are provided for most postulated high enorgy lino break (HELB) locations. !!owever, the S&L walkdown (6-13-85 through 6-18-85) of selected brock locations identified break locations in the Main Steam Tunnel (Room 4316) and the llPCI pump .
| |
| room (Room 4111) which woro unrestrained and could result in potentially damaging pipe whip. r No documentation could be found of an analysis to show that pipo !
| |
| whip rostraints woro providad to ensuro availability of ossential '
| |
| safety-rolated systems and components required in the ovent of a llELB.
| |
| Furthormoro, thoro appoars to be no formal documentation for an analysis to datormino pipo whip tip dofications, subsoquent to postulated ilELB for rostrained and ur.rostrainod piping, even -
| |
| though such an analysis apponra nocessary. For examplo, during '
| |
| the S&L walkdown of the llCGS drywall, it was datormined that lower RPV level sonsing lino 1-CCA-235 could bo impacted by pipo whip tip deflection duo to broaks in tho RWCU systom. Without tho analysed tip displacements, it cannot be datorminod if the sonsing lino will actually sustain damago subsequent to the llELD.

| |
| l l
| |
| : 1) The same source ( 1-KA- O ll-IIB D-1 " ) was identified on throo separato Record Shoots (461502, 03 and 04) which are not cross-referenced, thus in potential violation of the requirements in G-052. It was datormined during the S&L walkdown that the Record Shoots applied to throo difforont sectionn of the identified lino.
| |
| It apponrs that, for clarity, the piping section identified as the sourco should bo uniquely identified in ovary caso.
| |
| : 2) The ovaluations mado on the Hocord Shoots is supported by refuroncos.
| |
| In two conos (461506 and 530501) however, it could not be confirmed that the referenco supports tho evaluation.
| |
| : 3) Two Record Shcots (4G2604 and 462605) rubmitted for our review did not identify any intoraction. Thoso choots should not have been filod.
| |
| : 4) S&L han identified two potential sourcos in I:oom 5J05 which have apparontly not boon identified by tho Dochtul G-052 walkdown (no Record Shoots could be found). Thoso are:
| |
| The hangor on pipolino 1-MJ-154-4"-ilDD which is closont to the Dict 4ol Gonorator (not identiflod by numbor)

| |
| basis. Structures designed to onclose and separate high energy piping from essential safety-related equipment are designed to sustain the predicted jet impingement and pipe whip loads. Loss I of safety-related systems occupying the compartment where the postulated pipo break occurs is considorod in the ovaluation of the plant's ability to shut down, cool down or isolato."
| |
| General Specification 10855-G-019.1 states in Section 1.1.4 "The field walkdown will verify the adoquacy and complotonons of the home offico separation review. This e f fort will confirm the work previously accomplished, and document those intoractions on safety-related targots not previously identified."
| |
| l S&L has reviewed the DPC documentation resulting from the home offico separation review. The procons appears to be informal, incomplete and based primarily on undocumented engineering judgomont (OR No. 58). The reviewod documentation at the prosent timo doos not moot requiroments for dosign documentation as requirod by ANSI N45.2.11. Thoroforo, the G-019.1 walkdown becomes important to assure final design acceptability. -
| |
| However, based on the results of the walkdown (June 13 thru June 18,1985) and a review of the preliminary results of an l carlier (May, 1985) D?C walkdown, the G-019.1 walkdown as currently conducted, may not be adoquato for the above stated l purpo so,. The G-019.1 walkdown proceduro as currently conducted appears inadoquato for tho following reasons l
| |
| l a. The DPC and S&L walkdowns for broak location 565 upstream I on the main steam lino AD-022-DDD-26", resulted in I
| |
| identification of a difforont number of targots. Potential reasons for thoso differencos include:
| |
| - inaccessibility of components
| |
| - variation in judgomont regarding the jot impingomont zono, and a variation in judgomont in selecting the targeto (duo to physical shiolding, safety-related datormination and other critoria) 1

| |
| : b. The S&L walkdown team concluded that at some break locations a potential for damaging pipe whip existed (break location 70 downstream on the foodwater piping and break locations 45, 215, 385 and 565 downstream on the main steam piping) .
| |
| This potential for pipe whip has apparently not boon identified by the BPC G-019.1 walkdown, even though pipe whip is in the scopo of this walkdown. Further, thoro is
| |
| : apparently no evidence that pipe whip at those locations has boon addressed in the prior separation review dono
| |
| ! by the home offico.
| |

| |
| : c. During the Soismic II/I walkdown, S&L identified in Diosol Generator Room 5305 drain lino 0-LP-024-4" XNG. An assessment for dripping from drain linos is a part of the scopo of the G-019.1 walkdown. BPC has apparently performed the G-019.1 walkdown for this room; the documentation
| |
| * received t,o dato does not show that the DPC walkdown identified this drain lino.
| |
| Completo documentation for the DPC G-019.1 walkdown, could not be fully reviewod as it is not yet availablo. The prolininary documentation that was provided is not a completo documentation package for this walkdown. Ilowevor, what was reco1ved indicatos that the majority of the identified targots for jot impingement woro disposed of during the walkdown, somo by noting that the targots were not "onnontial". No supporting evidence was provided for thono decisions. Further, apparently no list of the canontial l
| |

| |
| : a. In the check of the weld on the gusset plate done on sheets 4 and 11 of.the subject calculation, the effect of the eccentric load application upon the weld does not appear to have been considered. In addition, it does not appear that the 11" length of weld required in the calculation was' specified on the design drawing.
| |
| : b. The basis for this 1/2" minimum gap billed on Section "A" of Drawing C-0845-0, Sheet 5, Rev. 8, for the sliding connection is not provided.
| |
| : c. The 1/4" all-around weld of the 1" web to the 1-1/4" plate as shown on Section "A" and the 1/4" all-around weld of the WT8x38.5 to the 1" thick plate, as shown on Section "C" of Drawing C-0845-0, Sheet 5, Rev. 8, does not appear to meet the minimum weld size requirement of the AISC Code.
| |
| d.
| |
| The check of the 1/2" one-sided weld of the shear lug to base plate (Section C, Drawing C-0845-0, Sheet 5, Rev. 8) done on Sheet 4 of the subject calculation is' based on a 5.5" weld-length. Review of Section C_ appears to show that only a 4.5" maximum weld length is possible.
| |
| : e. The subject calculation cover sheet lists Rev. 2 of the Dynatec R/D Company Seismic Analysis Report No. 1602 (Rev. 3) as a reference while calculations appear to be based on Rev. 1 of report. Some support reactions have increased in Rev. 2 of the report.

| |
| : 2. Descripticn of observation: (continuation) following items do not appear to have been considered:
| |
| a) Increased weight of stiffeners due to the fact that the true length of the duct stiffener may not be equal to the duct perimeter, but rather the duct perimeter plus the stiffener depth at each of the four duct corners, b) Additional weight of the second stiffener for companion angle joints.
| |
| c) Duct accessories and insulation loads.
| |
| d) Eccentric effects of duct accessories.
| |
| : 2) Self weight excitation of hanger members does not appear to have been considered.
| |
| : 3) On sheet 9 of subject ca'lculation, the O.B.E. condition is found to be critical. This was accomplished by comparing O.B.E. spectra acceleration values with SSE acceleration divided by 1.5 values (1.5 is the ratio of SSE allowables to O.B.E. allowables for steel). For supports utilizing expansion anchor plate assemblies, no overstress for the SSE condition is allowed over O.B.E. condition according to Note 3 of Table 6C-2 of the FSAR. This does not appear to have been considered in determining the critical seismic loading condition.
| |
| : 4) On sheet 18, an, assumption was made that a square duct was the worst load case for frequency determination and design of horizontal members. However, narrow and tall ducts (2:1 ratio) would appear to be the critical case. This does not appear to have been addressed.
| |
| : 5) The computer analysis for the hanger as shown on Sheet 40 uses a 9' length for the vertical member. This lengtn is (contil.ued on next page:

| |
| inconsistent with sheet BA2 of Drawing C-0388-0(O),
| |
| which allows a length for 11' for the vertical member.
| |
| . In the walkdown of tne HVAC supports it was identified that the maximum length of vertical members used was only 10' for longitudinally braced supports and 9'-0" ~
| |
| for supports only transversally Draced, as shown on Sheet 10 of the calculations. No attempt was made to reconcile the difference between calculations, drawings
| |
| , and as-built condition.
| |
| : 6) Lumping of the total mass of the duct at the intersecting node of the vertical with the diagonal member for horizontal excitation does not appear to account for the flexural effect of the vertical and horizontal members and the actual mass distribution of the duct on the support.
| |
| : 7) On page 56, the moment due to the 2.815" eccentricity of the longitudinal brace to the vertical member (Detail B-6, Calculation 625-82, sheet 56) does not appear to have been considered in the design of the vertical member.
| |
| : 8) Calculations for connection to the structure (pages 54 and 55) do not appear to consider the following items:
| |
| a) prying action b) check of the connection angle '
| |
| c) check for bending of supporting beam flange d) check of plate for Detail A-3
| |
| : 9) Detail Al shown on Drawing C-0388-Q (Q) , sheet cal, Rev. 3 allows for an optional 3/16" weld of the hanger to the flange of the building steel beam. Per AISC minimum weld size requirement, 3/16" weld is good for beams with flange thicknesses equal to or less than 1/2". For beams with flange thickness greater than 1/2", a 3/16" weld does not meet ATSC Code.
| |
| : 10) On sheet 56, a check of the PS3563 bracket does not appear to have been performed.
| |
| : 11) Dead load and live load combination as required by FSAR Table 6C-2, does not appear to have beer. addressed in the subject calculation.
| |

| |
| bent plate to the horizontal member does not appear to have been performed. -
| |
| : 14) No evidence was found that EDP 4.37, (Rev. 6), Item 3F was followed; specifically, identification of the program by number and name and the version or revision, including the option used in the calculation for the program used in calculations 625-82 (i.e. pages 19 through 24).
| |
| : 15) Section properties for duct of A=100in and Iz=1000in used in the computer program have no calculations or justification for their use. ' Response to TSB-178, Item 23, states that "these values were assumed."
| |
| : 16) Duct support dimensions used in the Calculation 625-82 (Q) are based on walkdown dimensions in Calculations 625-101(Q) and 102 (Q) as referenced on sheets 10, 11 and 12. The walkdown calculations are listed as " final" but neither acoear to be signed, checked, nor approved. Since the walkdown calculations provide input for 625-82 (Q) ,
| |
| the calculations are not in compliance with EDP 4.37.
| |
| : b. Type "M" Support
| |
| : 1) In the calculation for Dead Load, sheet 82, the following items are noted:
| |
| a) The assumption that the stiffener weight is 20% of
| |
| . the duct sheet weight has no documented bases.
| |
| Considering the stiffener size for 2-75"x84" ducts and considering the additional stiffener at the companion angle joint, a value greater than 20% may be calculated.
| |
| b) Loads due to insulation and accessories and the eccentric effect of these accessory loads were not considered. ,
| |
| c) The design of Type "M" support is done on the assumption that it carries a maximum of 2-75"x84" ducts.
| |
| However, Drawing C-0330,0, Rev. 14, for Type "M" support does not give any limitation on the number and size of ducts which can be supported by this support.
| |
| It is conceivable that from the dimensions of the support it may be able to accommodate larger ducts, thus increasing the dead load on the support.

| \ 2) Several members of the subject support Type "M" do not j
| |
| appear to have been addressed in the calculations.
| |
| \
| |
| The calculations for the vertical member which did have calculations, appeared to only consider bending about one axis. Axial load and bending due to the longitudinal load does not appear to have been considered.
| |
| : 3) In checking the adequacy of the P5000 horizontal on sheet 84 of the subject calculations, the 7 foot span of horizontal member, as permitted by the drawings, was shown to be inadequate while a 5 foot span was shown to be adequate. Limitation on the span length of this member does not appear to be indicated on the subject design drawing.
| |
| : 4) The dead load and live load combination as required by FSAR Table 6C-2, does not appear to have been addressed in the subject calculations.
| |
| : 5) The AISC Code is used as design basis code for Calculation No. 625-11(Q) , Rev. 4. This code is not applicable to UNISTRUT members.
| |
| : c. Detail 9 (C-0344-0) Support
| |
| : 1) In the calculation for Dead Load, sheet 158, the following items are noted:
| |
| a) The assumption that the stiffener weight is 20% of the duct sheet weight does not appear to have a documented bases. Considering the weight of the stiffener size required for a 72"x84" duct and considering the additional stiffener at the companion angle joint, a value greater than 20% may be calculated.
| |
| b) Calculation for Dead Load of support appears to be based on TS 6x6x5/16, instead of 7x7x5/16, called for on the design drawing, c) Duct insulation load does not apoear to have been ,
| |
| considered.
| |
| : 2) only the dead load plus S.S.E. load combinations are in-vestigated in the calculations. The checks for dead load i plus live load and dead load plus O.B.E. load combinations (
| |
| do not appear to have been addressed as required by PSAR Table 6C-2,

Detail 9 HVAC Duct Support, as shown in the subject design drawing, is unique to two locations. FCR #C-10813 combines the two unique hangers into one hanger whose configuration is completely different from the detail 9 shown on the subject design drawing. The subject calculation and design drawing does not' reflect the as-built situation as described by FCR-C-10813.

| |
| "That analysis of postulated pipe ruptures summarized in Section 3.6.2 verify that the consequences of any single rupture of fluid system piping in the plant do not prevent safe shutdown of the reactor".
| |
| Documentation was requested from BPC which addresses target survivability and methods of jet impingement protection for the
| |
| ! ADS system. In response to this request, page 44 of Calculation j SC-5, Rev. O, dated 10/22/83 was received. However, this page I
| |
| does not provide satisfactory documentation evidence that all :
| |
| ADS and safe shutdown targets were adequately evaluated for the j effects of jet impingement forces.
| |
| j l'
| |
| Likewise, it appears that there is no documentation which verifies that safe shutdown is achievable, subsequent to a HELB which l affects the ADS system. Per discussions with BPC, this was done 4
| |
| by undocumented engineering judgment based on the safe shutdown matrix of Design Criteria D7.3.
| |
| 2 l 4. Recommendation for Resolution: (continuation)
| |
| ] The analysis should include considerations such as:
| |
| I - Conclusive evidence that safe shutdown will be achieved per a failure modes analysis.
| |
| - A structural evaluation of all ESR and RSR targets, if necessary.
| |
| - Determination of whether the targets will survive the impingement and be able to perform their design function, j - An identification of the type of protection used for each target.

| |
| "The loading combinations for valve accelerttion shall be identical to those specified for the pipe."
| |
| Furthermore, Design Specification 10855-M-068(0) outlines the loading combinations for Class 2 and 3 piping, paragraph 6.2, page 15, in which Relief Valve Closure (RVC) transient, is defined as an emergency condition (DE) and dynamic events associ-ated with LOCA (DF) are addressed separately for upset, emergency and faulted conditions, respectively. Contrary to the above, the review of Calculation No. C-138-40, pages 48 through 50/62, revealed that only the maximum calculated acceleration values of the above mentioned vacuum breakers due to seismic loads were compared against tne allowables. However, tne maximum calculated valve accelerations due to SRV actuation or any other dynamic loads, for all operating conditions as defined oy the Design Specifications were not addressed in the calculations.
| |
| Furthermore, the maximum OBE acceleration value (2.364g) for vacuum breaker PSV-F037L, exceeds the allowable value (2.25g) and no technical justification or documented engineering judgment is given for acceptablility.
| |
| : 4. Recommendation for Resolution: (continuation)

Description of observation: (continuation) the reserve feed is initiated provided the reserve feed voltage is above 92%. (Note: A dead bus transfer is used in all cases unless the degr'aded condition is the result of a transformer i fault, in which case a fast bus transfer is initiated.)
| |
| When a degraded. voltage occurs where the 4.16kV supply voltage drops below the degraded setpoint of 92%, but remains above 70%,
| |
| the undervoltage relay on the incoming main feed will time out and trip the main offsite feed circuit breaker. The bus voltage will decay to the 70% voltage setpoint (2975V) of the bus instantaneous undervoltage relay (GE Type NGV). Operation of the bus undervoltage relay will close the reserve offsite feed breaker without delay and trip the 4.16kV bus motors following a 15 cycle delay. Because of the 15 cycle delay, the reserve offsite feed breaker will close before the motor loads are shed.
| |
| The resulting motor voltage may exceed 1.33 per unit.
| |
| ANSI Standard C50.41-1977 states that in order to limit the possibility of damage due to high transient torques, " ...it is recommended that the power supply system be designed so that the resultant vectorial voltage between the motor residual voltage at the instant the transfer or reclosing is completed does not exceed 1.33 per unit volts of the motor rated voltage basis."
| |
| : 4. Recommendation for resolution (optional): (continuation) the conditions described by this observation. Included should be calculations indicating compliance with ANSI C50.41-1977 or a technically acceptable alternate.

| The following concerns regarding the summary tables of Calculation 9 (Q) have been identified:
| |
| I
| |
| : a. Note 5 on page 13 of 43 to Calculation 9(Q) states that i operating kW of motors 250 hp or smaller is taken as 0.8 l
| |
| of rated horsepower. There is no apparent documented basis for 0.8.
| |
| : b. Page 4 of 43 to calculation 9 (Q) states a valve load of 20,5kW. There is no apparent calculation or written analysis to document the basis for the 20.5kW valve load.
| |
| Bechtel indicated that all valve loads were tabulated and divided by four to arrive at 20.5kW.
| |
| : c. Loads in Tables 1 through 6 are numbered sequentially, however, blocks of numbers are missing (e .g. , loads 4 2-45 and 64-70) without explanation.
| |
| : 4. Recommendation for resolution (optional) : (continuation) l horsepower requirements and missing item numbers in Tables 1 through 6.
| |
| : b. BPC should provide assurance that other electrical equipment sizing calculations contain documented assumptions and values.

| |
| Containment Final Stress Report, Section 6.2.1, (PDM-02-091, Rev. 4) the drywell vessel appears to be analyzed by applying only the shear forces which do not result in overturning moments as specified in the design specification.
| |
| : b. Local buckling analysis of the drywell vessel at beam seats does not appear to have been performed,
| |
| : c. It appears that the BPC Drawing C-0993-0, Rev.14, and the primary containment Final Stress Report, Section 4 (PDM-02-025, Re v. 3) have not been revised or reconciled to accommodate the revised dead load of 3200 lbs. at twelve circumferential points on the water seal plate as specified in the Design Specification C-152 (Q) , Rev. 11.
| |
| : d. The Plant Unique Analysis Report, Volume 2 (BPC-01-300-2),
| |
| Rev, 0, uses 122,000 ft.3 of water as a dead weight on the suppression chamber for all load combinations. This appears to be in conflict with Design Specification C-152(Q) ,

| |
| , The BPC model consists of 20 soli elements-and a stick model representing the superstructure.

| - The SSI FEM analysis to. verify the design basis seismic-analysis performed by Impell.
| |
| - The seismic impedance analysis for reconciliation of the design basis FEM analysis as per NRC requirements. -

| |
| : b. The RPV does not appear to be included in BPC's model. It appears that only the mass of the RPV has been lumped on nodal points of the bioshield and pedestal stick model. The RPV weight is approximately 4200 kips as compared to the total weight _of the bioshield and pedestal of~3275 kips. The RPV's stiffness and distribution of the RPV weight can affect local responses,
| |
| : c. As a result of the RPV stiffness not being modeled, the
| |
| ! rotational and translational springs corresponding to the j RPV stabilizer truss do not appear to-be included in the model.

Description of Observation: (continuation) performed based on the analysis of dead load, live load abnormal pressure, thermal load, tornado and seismic loads by the moment distribution method of a one foot rtical strip of the wall. Additionally, a calculated wide 0.98invg/ft of reinforcement steel in the hoop direction was required for abnormal pressure loading.

| U = 1.4D + 1.7L U = 1.4D + 1.9E U=D+L+W t and an additional thermal gradient of 70 F.
| |
| : 1) The above load combinations and thermal gradient i analyses do not appear to provide an assessment i for all load cases required by the FSAR. For example, some of the following load combinations might be the governing cases:
| |
| U = 1.2D + 1.9 E n U = D + T, + 1.5 P, U = D + 1.25 P, + 1.25 En.

| Attachment 3 of SC-16-1 indicates that: " Shear lugs for the following axial supports:

| |
| The enveloped moment loads are tabulated in SC-16-1 for load cases WTDW, SEISOB, SEISSS, SAMOB and THRMAL.
| |
| A review of the tabulated enveloped moments revealed that they do not consistently agree with the computer analysis results in C-138-40 for load cases NTDW, SEISOB, SEISSS. It appears that the enveloped moment values should be as follows:

| Furthermore, it was observed that hanger drawing number AB-057-H04 was mistakenly identified on sheet 7/11 of Attachment 3A of Calculation No. SC-16-1. The correct hanger drawing numberHis AB-057-H05.

| |
| The following discrepancies were noted relative to this requirement:
| |
| : 1) FSAR 3.9. l. 2. 5. 4 des cribes computer program NE452 for Relief Valve Discharge Line Reflood. This section of the FSAR states "Bechtel Computer Code VRV (NE452) is used for analyzing reflood transient in steam relief valve discharge to a water pool".
| |
| In a conversation between S&L and BPC (documented in L. Fergusson's Bechtel office visit report for dates 6/24 and 6/25/85) S&L was informed that NE452 was not used on the Hope Creek Project.
| |
| : 2) Program ME210, which is used in the qualification of welded i attachments to piping, is not listed in the FSAR.
| |
| : 3) Program ME909 merges response spectrum curves and makes plots i of the curves . It is used in the dynamic analyses of piping systems. Program ME909 is also not listed in the FSAR.
| |
| : 4) Program ME602 is used for spectra merging and simplified seismic analysis. This program performs the seismic anaylsis 4 of small bore piping systems (2 inch diameter and under) and generates a set of tables of seismic spans, support reactions, ,
| |
| and stresses for various pipe sizes. ME602 is not listed in the FSAR.
| |

| |
| The following items are noted regarding Calculation 675-9 (Q) ,

| Rev. 0: -
| |
| : a. In assessing HVAC duct supports as targets or as impactors during a horizontal seismic acceleration, a duct span length of only 10 feet appears to have been assumed. How-ever, for some of the HVAC supports, the duct span could be as large as 20 feet. Similarly, cable tray supports appear to be evaluated for an 8 foot support spacing while actual support spacing in the transverse direction could be as large as 16'-0".
| |
| : b. The unistrut members appear to undergo plastic deformations in the analysis for impact loads. No justification appears to have been provided that addresses whether these members are capable of developing full plastic moments.

| |
| The following scenario may occur in the event of a loss of offsite power during diesel generator testing:
| |
| : a. Since the diesel generator supports voltage on the bus, the CV-22 second level undervoltage relay will not operate. Therefore, the main breaker to the bus will not trip. The existing relaying system can not ;
| |
| detect a loss of offsite power with a diesel generator :
| |
| in testing, paralleled with the system. j
| |
| : b. Consequently, the diesel governor control will not switch promptly to isochronous control which may be i required to properly support the intended load. f The diesel generator may become overloaded and operate i below rated frequency until the overcurrent or under- L frequency relays will trip the' diesel generator breaker.
| |
| : c. With the diesel generator in test mode, supporting the i load on two channels (if during testing, prior to loss i of offsite power, two channels are tied together) , the j second diesel generator will not start until the diesel a undertest is tripped as described above or a degraded voltage condition is detected on the bus. ,

| |
| Reference 1.a, paragraph 6.2.2, briefly describes the requirements of Section NB-3653 of the ASME Code and states that: "Therefore the stresses due-to various load cases must be compared with one i
| |
| another to compute . stress ranges. All possible combinations of load cases.are evaluated by the rules of the Code to determine the maximum possible stress ranges."
| |
| 1 In the review of Reference 1.a, inconsistencies have been identified between the HPCI Steam Supply Load Histogram, Figure 6.1 and the-load combinations for Primary.Plus Secondary Loads,
| |
| * Table 6.2-2. 'These inconsistencies are:
| |
| i
| |
| : a. Load case SHUTDOWN is indicated on the Histogram, however, Table 6.2-2 describes this load case as COLD SHUTDOWN.
| |
| : b. On'the Histogram, the SHUTDOWN load case was not numbered as a load case. However, Table 6.2-2 describes this load case as No. 7.
| |
| : c. On the Histogram, the SHUTDOWN load case is defined ~as a variation of temperature from 546*F to 100'F,'with a thermal transient rate-of 100*F/HR, and pressure from 1000 psig to zero psig for 111 cycles. However, Table 6.2-2 de fines COLD SHUTDOWN as the zero load case (70*F initial and final temperature, zero psig for 120 cycles).
| |
| Review of Calculation' No. S-10855-1403 computer' analysis-results ' indicates that the COLD SHUTDOWN load case was considered as defined in Table 6.2-2 of Reference 1.a for the fatigue evalua tion . It appears.that the shutdown temperature
| |
| ' ~
| |
| transient defined by the Histogram was not accounted for.

There is a projection of approximately 11" from the center line of the stiffener to the end of the beam. No local stress check appears to have been made for the flanges of the beams as the vertical load is not directly transferred from the stiffener to the seat.
| |
| : e. The effect of horizontal seismic excitation on the design of framing.and the connections does not appear to have been addressed for the beams.
| |
| -f. The calculation of effective size of the partial penetration welds, namely the reduction of 1/8" from the size of the weld does not appear to have been done for-some of the welds as required by AISC Code Section 1.14.7. For example, see.
| |

| |
| The effect of the difference in the elevation between center lines of various framing members does not appear to have been addressed in the analysis of drywell framing for horizontal loads.

| |
| : 1. Calculation 624-28 (Q) has multiple calculations addressing the design of the same structural element. None of these
| |
| >' . calculations are' indicated as being void. It is not clear.
| |
| which calculation controls. Example: 624-28(Q) sheet 10 shows a calculation of-a box beam with a pipe whip load.
| |
| Sheet.109 shows additional effects of thermal loads plus pipe whip load, sheet 10 does not mention the calculation on 109.
| |
| m.- In Calculation 624-26 (Q) , the design of connections for .
| |
| PWR Member-bbl to' column members of CE for PR-ll4 controls j' design of these columns. Page 64 of the calculation indicates columns'overstressed with fixed-fixed connections for bbl.
| |
| Connections were' revised to simple supports and columns were shown to be adequate. Reference is'made to page 67.for the connection design. However, page 67'contains connection design calculations-for a stability load only.. Also, the
| |
| -connection appears-to be a fixed connection instead of simple support.
| |
| : n. Documentation for the north pipe whip tower is not clear.
| |
| It.cannot be determined'whether the impact of each PWR reaction
| |
| ! on the support framing at' Elevation 100'-2" and 121'-7h" has been properly considered. The design basis.for both overa,ll and local effects is'not clearly stated.
| |
| : 4. Recommendation for Resolution: (continuation)
| |
| : b. BPC should provide-assurance that calculations for other framing in the drywell adequately address the observations described in Section 2.

The effect of small' attachments like conduits, cable trays, HVAC ducts, piping smaller than 2 " etc., is simulated by an equivalent dead.loadlof 50 psf. This may not properly represent the total' reaction from these components due to the following reasons:
| |
| : 1. The effect of some point loads may exceed that of.the 50 psf uniform load.
| |
| : 2. The horizontal reactions from the' components do not
| |
| ; appear to be accounted for.
| |
| : b. For beams supporting concrete slabs, the horizontal forces
| |
| ~
| |
| due.to the reaction from component suoports do not appear to be addressed in the design of tne beam end connections.
| |
| : c. Sheet 24 of Calculation 621-29 (Q) appears to allow a local bending stress of .75F in the flange of wide flange sections.
| |
| The interaction of locEl and overall stresses does'not
| |
| * appear to be addressed.
| |
| ; d. Load verification calculations appear to have been~ prepared with no reference to the current design basis calculations (i.e. 64 4- (Q) 11, Rev. O, " Load Verification -- Auxiliary i Building Control Area, El. 77'-0", do not refer back to the design basis Calculations 6 4 4- (0) 8, Rev. 2).
| |
| : e. The procedure used by Bechtel for final load verification i appears to be based on individual room turnovers. The load verification procedure does not appear to require that common boundaries of adjacent . rooms be included as part of
| |
| .the load verification ' (1.e. floor loads from one room may not be considered with the ceiling loads of the room below).
| |
| It appears.that the verification procedure does not address-subsequentLchanges to a room not yet turned over on a room

| |
| Class lE switchgear by Bus Duct 1AX108 and Transformer 1BX501 is connected to each Class 1E switchgear by Bus Duct .AX109. Bus Ducts LAX 108 and 1AX109 are-both routed through common areas of
| |
| . Turbine: Building, Service and . Radwaste Area and Control and Diesel Generator Area.- In addition, both bus ducts are routed throuch each diesel generator room together.with each diesel generator feed to the respective. Class lE switchgears.
| |
| This design is not in accordance with the intent of GDC 17 which
| |
| . . states that the offsite sources shall'be supplied by two physically independent circuits designed and located so as to minimize,to the extent practical,the likelihood of their simultaneous failure under operating and postulated accident-and environmental conditions.
| |
| The common routing of the two bus ducts may expose both offsite sources to common hazards such as fire, environmental and. missile design base accidents such as pipe whipping and discharging fluids.
| |
| The com-on routing-of both offsite. sources and each division's
| |
| ; (channel) onsite source (diesel generator) in each diesel generator i
| |
| room provides the possibility of losing both offsite sources and one diesel generator to a common event such as a fire in the diesel generator room.

The spacing between'the anchors can.be reduced to a spacing less than the 10d required by C-136 and there is a possibility that due to overlapping shear cones, a concrete cone failure may control the capacity of the expansion anchors. It is not apparent how the possible reduction of allowable expansion anchor capacity is considered in either the " BASEPLATE II" computer program or the calculations,

The calculations (Appendix A, Page 29) appear to indicate that the brace is necessary for lateral stability of the platform.
| |
| : d. Platform R-162-2 on Drawing C-0 859-0 (Q) , Rev. 5, appears to indicate that Detail 1 on Drawing C-0319-0(Q), Rev. 4, is to be used for attaching the column base to the floor slab. Detail 1 on Drawing C-0319-0(Q), Rev. 4, and Page 13 of Appendix A of Specification 10855-G-050 (Q) indicate that 4-3/4 9 expansion anchors are to be used.

HPCI System Logic diagram J-55-0, Sheet 5, indicates two logic paths to open valve: 1) the control switch and 2) continuation to completion of valve opening once valve action has been started (i.e., seal-in). Path 1 only, includes a GE permissive (interlock) to stop or prevent valve opening when an HPCI isolation signal is present.
| |
| ' Schematic E-6076-0, Sheet 2, also indicates the same two paths as the logic diagram for valve opening, however, the GE permissive (interlock) to stop or prevent valve opening when an HPCI isolation signal is present it included in both opening paths.
| |
| Per the logic diagram, if an HPCI isolation signal is received during opening of the valve, the valve will continue to its 100% open condition before it starts to close (closing is also a function of the HPCI isolation interlock); however, per the schematic, the valve will stop opening immediately and start closing.

| |
| In this calculation, an application table (Table 3) was developed for six different loading conditions of the 200VA, 480-120V control power transformers used on the Hope Creek Project. This table indicates maximum acceptable circuit lengths for the six postulated typical transformer loading conditions. The tabulated maximum allowable control circuit lenghts are used in the design process as a guide to determine if a particular control circuit / loading con-figuration is acceptable.
| |
| The six application cases described in Table 3 do not include solenoid valves among the loads which are energized. Even though the sketch on page 18 of Calculation 17A(Q) " illustrates the simultaneous energization of starter coil (42) or M relay and Agastat timer followed by a solenoid valve," there appears to be no design application guidance in the 17A(0) calculation which would indicate whether or not a particular circuit involving a solenoid valve is acceptable from the circuit length standpoint, despite the fact that circuits including remote solenoid valves may be more limiting than any of the six cases analyzed in the 17A(0) calculation. For example, ASCO 8300 series solenoid valves have (per page 2 of the calc.) a 250VA inrush and (per ASCO catalog) require 85% of 120V to pickup. This voltage requirement is higher than that associated with other remote heavy inrush loads used in the calculation. It appears that there is no document which controls the design of circuits involving solenoid valves from the point of view of determining whether a particular circuit length to the solenoid valve is excessive.

| : 2. -Description of Observation: (continuation) time the devices must be picked up." Calculation 17A(Q) utilized a minimum bus voltage of 0.9 pu at the 480V MCC to establish the maximum control circuit cable lengths in ac control circuits for various starter sizes and control conductor sizes. Calculation i 15(0) established a minimum bus voltage of 0.7848 pu at MCC l
| |
| 10B583 during an accident scenario. Calculation 15.l(O) which covers the bus voltages for various scenarios established the minimum bus voltage for MCC 10B583 as .8617.
| |
| Since Calculation 17A(Q) did not utilize the minimum bus voltage at the MCC, it is possible that insufficient voltage will be 3
| |
| available to energize (pick up) the starter coils of safety related loads when required to respond to design basis accidents.
| |
| It is recognized'that the minimum bus voltages indicated in Calculations 15 (O) and 15.1(Q) occur during motor starting sequences, however, no indication is provided as to when the bus voltage will recover sufficiently to allow the starter coils to be oicked up. Therefore, it is not possible to establish that '
| |
| the safety related loads fed from the 480V MCC will complete their safety function within the required time.

Second there appears to be no documented analysis to verify the safety related loads fed from the'480V MCC will perform their safety function within the required time taking into account the possible additional time delay associated with the voltage recovery at the 480V MCC buses.

| : 2. Description of Observation: (continuation) unacceptable voltages would occur at the 480V level. Several cases of plant operation were analyzed. Sheet 24 of the calculation concluded that in one case 0.9102 pu at 4.16kV leads to degraded conditions and in another case .9181 pu at 4.16kV leads to degraded conditions. It is not stated which degraded condition governs the design. Furthermore, the FSAR Section 8.3.1.2.1 states that "the minimum acceptable 4160V bus voltage should be above .9087 pu". Based on the determination of minimum acceptable bus voltage, the second level undervoltage protection relay setpoint is determined in order to protect against sustained degraded conditions. This-setpoint has been determined to be 0.92 (based upon a .9181 pu degraded minimum acceptable bus voltage). It would appear that a higher setpoint for the second level protection should have been considered in order to account for the +3%
| |
| acceptance criteria associated with the Westinghouse undervoltace relay, and the use of a non-standard relay tap required to achieve a 0.92 pu pick-up.
| |

| |
| : b. BPC should commit to revising the FSAR so that it is in agreement with the results of Calculation 15.l(Q), relative to the minimum acceptable degraded voltage.
| |
| : c. BPC should commit to reanalyzing the setpoint of 0.92 for the second level protection addressing in the reanalysis the relay manufacturers acceptance criteria, and the effect on relay performance of using a non-standard calibration tap.
| |
| : d. BPC should identify the design review process which controls the determination of protection relay settings, and indicate why it did not address the concerns of this observation.

| : 2. Description of Observation: (continuation) conditions. Numerous cases were analyzed in Calculation 15(O).
| |
| The cases specifically related to the Class IE switchgear were discussed during the meeting with BPC. in San Francisco, June 16 and 17, 1985.
| |
| In addition, to the scenarios presented in BPC Calculation 15 (Q) ,
| |
| other operating scenarios exist which are not addressed by this calculation. Specifically, the following two cases are of concern:
| |
| : a. The loss of-a single offsite power supply occurs simultaneously with a LOCA such that the fast bus transfer occurs and the loads sequenced without.first adjusting the transformer taps.
| |
| The transformer taps are held fixed at their value for normal plant operation.
| |
| : b. 'The offsite power supply system is also designed to operate on
| |
| , a dead bus transfer. This case is not addressed by Calculation 15 (O) . A dead bus transfer is initiated when an offsite power supply is lost-for a condition other than a transformer fault.
| |
| Since only a single offsite power supply is lost'and not a complete loss of offsite power, the restart of loads following a dead bus transfer is not controlled thru the sequencer. As a result, those loads with maintained start signals and process signals will block start. BPC did provide a calculation to demonstrate block start capability on a dead bus transfer with normal plant operation; however, this may not be a worse case scenario, since it did not involve LOCA loads.
| |
| : 4. Recommendation for Resolution: (continuation)
| |
| : b. BPC should provide assurance that all credible. plant operating modes are enveloped by Calculation 15 (Q) .

| |
| : a. The penetrations are provided with primary and back-up over-current protection. Primary protection for the 480V MOV penetrations is provided by magnetic only circuit breakers and motor thermal overloads. Back-up protection is provided by thermal-magnetic circuit breakers. Since, during a LOCA, the motor thermal overload elements of the primary protection are bypassed, there is no primary short circuit / overload protection for current magnitudes below the magnetic breaker pick-up setting.
| |
| L b.- Continuous current carrying capabilities of the penetrations are not indicated on the coordination curves contained in 1
| |
| Calculation 7.13(O). The penetrations may not be provided
| |
| . with proper overload protection. For example, Figure 3 of Calculation 7.13 (Q) illustrates protection for #4 AWG penetrations. The 100A HFB breaker used does not appear to provide overload protection to the subject penetration, which according to Table 1 of Calculation 7.13 (Q) is rated at.74A.
| |
| : c. Maximum available short circuit currents for various size penetrations are not indicated on the coordination curves contained in Calculation 7.13 (Q) . Without establishing the
| |
| , maximum available short circuit at a penetration, it may nqt be possible to determine whether the short circuit withstand capabilities of the different size penetrations are not exceeded by the design.
| |
| : 4. Recommendation for Resolution: (continuation)
| |
| : b. BPC should provide verification that all electrical penetrations are properly protected for applicable overload /
| |
| high impedance faults as well as for high magnitude.short circuit currents, given single random failure.of current overload protection devices.
| |
| : c. BPC should identify the cause of this observation, the design control process, which should have prevented it and why the process did not prevent the observation.

| : 2. _ DESCRIPTION OF OBSERVATIONS:
| |
| A.
| |
| The S&L observation cites a lack of infomation from the vendor regarding test instgumentation, calibration records and traceability. This infoma-tion was provided by the vendor in a letter to BPC dated 10/19/82, and is identified'as CCN #226099 which is attached to this reply.
| |
| B. The observation identifies an inconsistancy of infomation between DITS 7.5 and the EESS with respect to operating time requirements. It should be.noted that the DITS 7.5 data was incorrect and will be revised to agree with the EESS and shown on the attached BPC memo dated 6/10/85.
| |
| C.
| |
| The observation alleges that the EESS infomation does not substantiate a 40 year qualified life because of a failure to meet operating time requirements and temperature requirements for aging. The latest EESS for this equipment properly addresses these topics and is attached for reference.
| |
| D.
| |
| The observation again cites a discrepancy related to operating time requirements. The reference in this case pertains to the DBE test profile and margin associated with the 100 day operating time. This item is properly addressed in Note #5 of the latest EESS.
| |
| : 4. RECOMMENDATION FOR RESOLUTION:
| |
| A. .
| |
| Each area of the observation has been addressed in the reply to para-graphs 2(A)-2(D) above. The additional infomation to support the reply is attached.
| |
| B. The intent of the FSAR statement was to provide an indication to the NRC that the Hope Creek EQ program is attempting to meet the latest .
| |
| requirements for EQ even though the plant is not required to do so.
| |
| At the time this section of the FSAR was written, it had not yet been
| |
| . detemined if the Hope Creek equipment could. meet the latest requirement.
| |
| f.
| |
| BPC and PSE&G are cognizant of the pertinent IEEE 323 requirements. All EQ reports have been, and continue to be, reviewed against the 1974 ver-
| |
| : i sion of the standard. Assurance of this review is maintained in the backup files which support the actual NRC audit packages.

| |
| : 2. Description of Observation: (continuation)
| |
| FSAR Section 3.11.2.1 and 3.11.2.3 states that HCGS EQ program is committed to NUREG 0588, Category II and IEEE 322-1971, but is attempting to upgrade to NUREG 0588, Category I and IEEE 313-1974.
| |
| The Equipment Qualification Audit Package Checklists indicate compliance with IEEE 323-1974,
| |
| : a. FSAR Section 3.11 states that the environmental qualification is attempting to upgrade to IEEE 323-1974. Paragraph 6.1 of this standard requires the qualification documentation to include " identification of Class lE equipment being qualified."
| |
| The environmental qualification audit binder identifies the manufacturer (Raychem), and the model numbers of the splices tested but not the model number (s) of the splices installed.
| |
| : b. The Equipment Evaluat' ion Summary Sheet (EESS Sheet F48561-TINS-001, Rev. 02) and the Equipment' Qualification Maintenance and Surveillance Information Sheet, MS-FLD-VAR-H-TINS-0 0 5, Rev. 05 contain inconsistent data. The LOCA parameters are defined for inside containment, while the normal environmental parameters are defined for outside containment rather than inside containment. This appears to be only a data inconsistency i
| |
| since the qualification tests use the inside containment parameters.
| |
| : c. IEEE 323-1974, paragraph 5 (1) , requires assurance that the severity of the qualification meets or exceeds the maximum anticipated service requirements and conditions. There is no calculation demonstrating that the test profile envelopes the plant unique LOCA profile.
| |
| : d. DITS 7.5, Rev. 2,- Table 5,' indicates that equipraent must be
| |
| ' environmentally qualified for 180 days post LOCA. Actual testing was performed for only 30 days post LOCA. Document CCNf0271401 (in the audit package), dated 9/17/84, page 8, states that the 180 day requirement is satisfied by taking credit from thermal aging testing performed before the LOCA te s t'. This does not meet requirements of DITS 7.5 or -

| : 2. DESCRIPTION OF OBSERVATION:
| |
| A.
| |
| The observation cites a lack of model number identification for the splices to be used at the plant to verify that they are the same as those tested by the vendor. . The model number of splices to be used in the plant are identified'on the EESS as WCSF-N.
| |
| specifies the use of this splice. Bechtel document E-1408 requires and B.
| |
| The observation provided for the cites spliceinconsistencies kits. between the EESS and EQMSIS pages sistancy and are attached for reference.These sheets have been revised for con-C.
| |
| The observation ability of the testcites the lack of a calculation to demonstrate accept-profile.
| |
| This calculation is attached for reference.
| |
| D.
| |
| The observation addresses the suitability of the method used to age the equipment.
| |
| in 2C above. This item is also addressed in the calculation referenced

| : 4. RECOMMENDATION FOR RESOLUTION:
| |
| A.
| |
| Each item of the observation report is addressed in 2A - 2D above.
| |
| B.
| |
| The subject cable splices have been shown to meet all applicable require-ments and the installed splices are representative of the. qualified splices as described in section 2 above. ,
| |
| C.
| |
| PSE&G is cognizant of the requirements noted and is actively reviewing all EQ packages for suitability of documentation. '

| |
| NUREG-0588, Category I requirements. NUREG-0588, Catego'ry I, invokes IEEE 323-1974. The subject EQ audit package specifies compliance to IEEE 323-1974 requirements.
| |
| Section 6.6 of the IEEE 323-1974 states that a periodic replacement plan shall be instituted to maintain the qualification status of equipment.
| |
| Based on review of the Environmental Qualification Maintenance and Surveillance Information Sheet (EQMSIS) which is in response to Section 6.6 of IEEE 323-1974, for Audit Package F37917(Q) (Buchannan Terminal Blocks), there appears to be a lack of direction to plant personnel relative to the following EQ related maintenance activitieC
| |
| : a. Required parts replacement intervals (necessary to maintain the qualification of the equipment) are not defined, but rather must be determined by field personnel from regression line curves.
| |
| Determination of the required replacement interval is contingent upon correct interpretation of the curves. -There appears to be lack of direction to field personnel regarding correct inter- -
| |
| pretation of these curves in that:
| |
| : 1. There is more than one regression line per package, there is no direction as to which curve is to be used. #
| |
| : 2. Use of the curve requires determination of temperature, there is no direction as to how this temperature is to be determined or what temperature is to be used (e.g. , minimum, maximum, average, mean).
| |
| : b. The EOMSIS identifies the manufacturer only, does not identify the model number.or part number. Lack of such information could potentially degrade the maintenance program.
| |
| : 3. Significance of Observation: (continuation) adequate. Therefore, the equipment qualification program may be invalidated.
| |
| : 4. Recommendation for Resolution (optional) : (continuation)
| |
| : b. BPC/PSE&G should provide assurance that all EQs for similar
| |
| ' [ ' equipment have adequately considered the subject IEEE 323 requirements.

| |
| Response to Description of Observation
| |
| : a. :The original calculations for the expansion anchor plate shown on sheet 3.24.386 of Drawing E-1406 are sheets 346-350 of calculation 677-3(Q),
| |
| which was prepared on 11/6/79. This calculation determines conser- l vative reactions, tension on anchor bolts and shows sizing of base
| |
| ! plate. The welds were approved by engineering judgement. Calcula-tion 677-222(Q) Rev. O was prepared for documentation purposes and i l confirms the adequacy of the engineering judgement.
| |
| b.1 Calculation 677-222(Q), Rev. O, was done using the worst-case as-sumptions based on actual and reasonable field practice. The critical condition for EABs is when the column is as far as possible j
| |
| .from the embed. The condition assumed for calculation 677-222(Q), l Rev. O is shown on attached Figure 1. The condition shown in Figure 2 is theoretically possible and has been evaluated in calcu-
| |
| !, lation 677-222(Q), Rev. 1, although the condition is highly unlikely.
| |
| , Even using the Figure 2 configuration-and other conservative assump- '
| |
| tions, the concrete expansion anchors meet design criteria. Calcu-lation 677-222(Q), Rev. 1, will be sent to S&L by 6/27/85.
| |
| b.2 The intent of the cope, as stated in Note 1 on sheet 3.24.386, is ,
| |
| to allow enough room from the edge of the embed plate to accom- l modate the weld to the EAB plate. The field engineers, who know :
| |
| the intent of the cope, ensure that excessive coping does not occur.
| |
| Furthermore, a conservative analysis was performed in calculation ,
| |
| 677-222(Q), Rev. 1, and shows that with only 4.4" of plate (3.8" l
| |
| . of cope on each side) the plate and weld will meet design criteria.
| |
| See Figure 3.
| |
| Response to Recommendation for Resolution
| |
| , a. The adequacy of expansion anchor plates is either specifically
| |
| & addressed in the individual support calculations, or is approved
| |
| ; b. by comparison to the existing calculations and by engineering 1 judgement. The expansion anchor plates'are reviewed for the max-
| |
| ! imum allowable eccentricity stated on the design documents or, if I none is stated, the " worst-case" eccentricity. During the design
| |
| , process, the engineers have developed knowledge of the capacities 2
| |
| of the expansion anchor plates and use this knowledge to confirm
| |
| ~
| |
| j adequacy of the detail based onfjudgement or comparison.
| |
| i Only detail 86 allows coping of the plate and this condition is i addressed-in Calc 677-222(Q), Rev.1.

| |
| -c. Use of engineering judgement to approve minor variations (such as the cope) to the baseline design is an accepted method in the de-sign process. Therefore, there is no deviation from the design control process. As part of the reassessment program, the adequacy of expansion anchor plates will be addressed for all applicable supports .

| |
| (ContinCation sheet) R/CR No7FT~ Rev. O Date bl261s( i 4.a Calculation C-33-20 mentioned in OR-93, Rev. O, was first per- -
| |
| formed by Impell Corporation (formerly EDS Incorporated) under contract with Bechtel Corporation. As required by EDP 4.58, Sec-i tion 3.2(d) titled " Supplier Calculation and Test Results", this calculation was reviewed by Bechtel to:
| |
| i I a) assure that work is in compliance with the specification; i b) assumptions and criteria are consistent with the project j criteria; c) to the extent needed, to determine that the calculations are sufficiently comprehensive.
| |
| -Since the detailed geometry check of the supplier work is not spe-cifically required by EPP 4.58, the discrepancy in OR-93 was
| |
| ; missed. . Later revision of the same calculation (Rev.20) was
| |
| ; performed by Bechtel to incorporate the spectra changes identified
| |
| ! by the Civil group. Since this discrepant area was not revised at i that time, no geometry check was performed of this area per our
| |
| ! procedure. In other words, Rev. 20 was performed to incorporate i only the effects of spectra change on calculation.
| |
| i It is our engineering judgement that, since this discrepancy was ,
| |
| ! locally confined to one area, its effect on the overall calculation I
| |
| would be minimal. To confirm the judgement, a study run was made
| |
| ; and will be sent under separate cover by June 28, 1985. The study j run showed the pump nozzle and piping code stress allowables were j not exceeded. !
| |
| 4.b The aBR program would have addressed this discrepancy. As is outlined in our ABR program, the as-built condition of the pipe geometry and other parameters such as supports, insulation, valve j weights, etc., will be reviewed against the current calculation
| |
| : and any such discrepancy will be reconciled either through en-
| |
| ! gineering judgement or performing revised calculations. Appendix i L of the As-built Reconciliation Procedure provides a checklist 3 for analyst to verify that all such parameters have been reviewed and found acceptable by him.

| ; 4.a Flange joints are analyzed on Hope Creek Project as required by ASME Section III Code. There are a total of 14 flanges in cal-culation C-1750-30 As is evident from this calculation, 10 flanges were analyzed and 4 flange analyses were inadvertently missed by the analyst. We have performed flange analyses at data j points 320, 340, 410 and 430 and have found them to meet ASME s
| |
| ; Section III Code allowables. A copy of our evaluation will be
| |
| ! transmitted under separate cover by June 28, 1985 for your review.
| |
| ^
| |
| 4.b As is evident from the calculation submitted to S&L within the IDVP j scope, flange joints have been analyzed in accordance.with Stress l Group procedures and ASME Section III requirements. However, if j there are any instances where such analysis may have been inad-i vertently missed, such discrepancies will be picked up during l as-built reconciliation . Appendix L of As-Built Reconciliation
| |
| ; Program, requires the analyst to verify the flanges (Item 4.a of the checklist) have been appropriately analyzed, It should be jl noted here that because of very high allowables of Mfs and Mfp;'
| |
| i permitted by the Code, it is our experience that once piping code allowables have been met, the flange joints have no problems meeting the allowables.
| |
| 4.c Stress bulletins are generated by the Chief Engineer's staff. '
| |
| These bulletins ~ provide discussion and guidelines on subjects
| |
| , which are generic in nature with the intent of maintaining unifor- l
| |
| ; mity in dealing with those subjects on all Bechtel San Francisco i projects. The bulletin documents subjects ranging from Code interpretations to new employee indoctrination. These bulletins also serve to inform projects which are in design phase of the experiences of the completed or near-completed projects.
| |
| I The bulletins are transmitted by the Staff stress group supervisor to the Project stress group leader. As directed in the letter,
| |
| , this information is disseminated to all the members of the project j stress group. These bulletins are filed and maintained current by j the stress group on the project. The specific use of'the bulletin l in any calculation -is so noted by the analyst on form P-1306B of j the stress calculation. In addition, where bulletins have been l used as guidelines in generating project stress group procedures, i they have been so noted in appropriate sections of the above
| |
| {
| |
| procedure. The approver of the calculation verifies the applica-
| |
| ) bility of the stress group bulletin to any calculation. This pro-i cedure has been implemented throughout the calculations performed on the Hope Creek project.

| l 4.a The reference document listed in OR-97, Section 1.c, was revised on 12/12/83 by Pittsburgh Des Moines (PDM). PDM issued a "Re-
| |
| ; vised Nozzle Load Design Check", Document #10855-C1520-2874-1, that addressed stress calculation 1547-20 leads. (The letter that transmitted these loads to Mechanical group is included as
| |
| !. Attachment 2 of 1547-20 Above PDM document will be sent to
| |
| } you by June 28, 1985.)
| |
| From page N31 of the revised PDM report "The controlling load in the revised nozzle load design check, Section NWZ, causing the overstressing of the shell plate is the faulted moment, Mz. This moment is approx. 2.0 times greater i than Mz in the existing design, stress report, (Section] V-B. To prevent any overstressing, this moment needs to be reduced by 344,
| |
| - assuming no other load or moment is changed, in order for exist-
| |
| ! ing design to be adequate."
| |
| Reanalysis.of the faulted condition resulted in revised faultid i
| |
| loads sent to PDM on 8/21/84 via letter number BLC-1483. The I normal and upset loads remained unchanged and, as stated above, did not contribute to the overstress condition. PDM's letter CLD-152-3398, dated 12/12/84, advised Bechtel that the new faulted loads are acceptable. Therefore, the accumulators have been verified to take the calculated nozzle reactions. Letters BLC-1483 and CLB-152-3398 will be sent to you by June 28, 1985.

| ! 4.b In the stress analysis of the piping system, the allowable loads j on the equipment are obtained by the analyst from one of the j following sources:
| |
| a) letter from vendor; ,
| |
| 3 b) allowables given directly on the equipment drawing;
| |
| ; c) allowables provided in Bechtel Design / Tech. Specs.
| |
| i
| |
| : The exact source of allowable nozzle loads is identified by the

| ! stress analyst in his calculation package. If the allowable load, as given, cannot be met, the cognizant engineer in the Mechanical /
| |
| Nuclear discipline is contacted (see attachment 2 of stress cal-j ulation 1547-20). The appropriate vendor is contacted and the
| |
| ; overload condition is resolved either through additonal re-analysis j on the part of the vendor or additional supports on the piping system. This resolution is documented through letters and tele-cons or modifcation of the vendor drawing. The procedure for're-solving an overload nozzle condition is discussed in Stress Group

| i 4.a The effect of localized stresses induced in the pipe by integral t.
| |
| attachments -is considered on Hope Creek Project. Appendix L, titled " Welded Pipe Attachment Evaluation Procedure" of Hope a
| |
| Creek Stress Group Procedure provides necessary guidance and docu-mentation requirements to the analyst for local stress calculation.
| |
| l The documentation requirements vary depending upon the type of <
| |
| 7 welde'd attachment e.g., rectangular lug attachment, stanchion type i support or anchor, sleeve type anchor, etc. As is recommended in i i Stress Group Bulletin 97 and position adopted by the project in
| |
| ! Section I of Appendix L, the effect of localized stresses due to
| |
| ! plate type anchor is accounted for by putting stress intensifica-tion factor (SIF) equal to 2.1 at the anchor point. There is no 1 local stress calculation required for plate type anchor other than i inputting.the above SIF in ME101 input and confirming the resulting l intensified stresses meet the code allowables. In this particular j instance, support drawing No.1-P-BJ-005-H01(Q) is a plate type '
| |
| a anchor. Although SIF value of 2.1 was not input in ME101, it is
| |
| ; the judgement of the approver (based on direct multiplica- L i
| |
| tion of calculated stress times 2.1) of the calculation that
| |
| ! because overall stresses in the system are low, there is no prob-4 lem in meeting code allowable stresses taking into account localized
| |
| { stress effect. This is verified in our calculation being trans-
| |
| ; mitted separately by June 28, 1985.
| |
| a ,
| |
| These calculations clearly demonstrate that ASME Section III code
| |
| ; allowables have been met. Also the maximum stress ratio of 0.47
| |
| ; (calc. stress / allowable stress) is well below the allowable of 1.0.
| |
| 4.b The effects of integral attachment on the total pipe stresses have
| |
| ; been evaluated on Hope Creek project. As discussed above, Appen-dix L of the Stress Group Procedure has been utilized to provide
| |
| ! such documentation. Local stress calculations are filed as at-i tachments to the main calculation to provide assurance that during i revision of the main calculation, the local stress calculation i update will not be missed.
| |
| ! Appendix L of the As-Built Reconciliation Procedure provides the j analyst with checklist item 2(e) to assure that welded attachment calculations have been performed and discrepancies, if any, recon-
| |
| ! ciled at.that time.

| |
| The observation cites a lack of specific direction to reviewers of EQ documents regarding compliance with daughter standards of IEEE-323 and the lack of obdective evidence to ascerttain that such standards were met.
| |
| PSE&G review practices are geared to the use of checklists which meet the requirements of IEEE-323 and not daughter standards. Compliance with daughter standards, which generally amplify IEEE-323 or provide guidance, is considered during the review of documents provided by vendors to show compliance with BPC specifications. The required degree of compliance with these standards is evaluated by the PSE&G engineers in conjunction with any necessary support from 'BPC engineers. Judgments made in this process are documented by letter or telecon and are kept in a file of supporting infomation for each purchase order.

| NUREG 0588, Category I requirements." NUREG 0588, Category I invokes IEEE 323-1974. The subject EQ Audit Package indicates compliance with IEEE 323-1974.' The subject Environmental Qualification Report is deficient with respect to the requirements of IEEE 323-1974 for the following reasons:
| |
| a.
| |
| Information contained in the Equipment Evaluation Summary Sheet (EESS) is not consistent with data defined in DIT 7.5 and does not meet the intent of IEEE 323-1974.
| |
| : 1. IEEE 323-1974, Section 6.3.1.5, paragraph 6, states that the qualification test shall include a +10% margin over the period of time the equipment is required to be operational following the design basis event (DBE). The qualified duration of 102 days as stated in the EESS does not meet this requirement of IEEE 323-1974 which would dictate a 100 x 1.1 = 110 day duration.
| |
| 2.
| |
| Per the EESS, the Buchannan Terminal Blocks can be used anywhere in the reactor building, except the torus area.
| |
| The identified environmental- temperature and pressure used for qualification are not consistent with the required enveloped reactor building environmental conditions defined in DITS 7.5.
| |
| b.
| |
| Information contained in the Equipment Environmental Qualificatio Review Checklist is not consistent with data defined in EESS and the stated references are not traceable (i.e., see Equipment F Qualification Review Checklist and Franklin Research Center Qualification Test of Terminal and Fuse Blocks, Report No.
| |
| F-C5143, dated July 17, 1980).
| |
| 1.
| |
| t Section 3.1.2 of the Review Checklis't addresses two types of terminal blocks, while the EESS only defines one type of terminal block.
| |
| l
| |
| : 2. Section 3.1.3 of the Review Checklist defines qualified life of the terminal blocks as 126 years at 500C, while the qualified life stated in the EESS is 40 years at 503 C.

| |
| A.
| |
| The observation cites deficiencies in operating time margin and incon-sistancy between qualification parameters and conditions at the locations of the teminal blocks. PSE&G has performed supplementary calculations which demonstrate the time and temperature margins available from the qualification testing. The EESS has also been revised to clarify the applicability of the qualification for the locations of the teminal blocks.
| |
| These documents are attached for reference.
| |
| B.
| |
| The observation cites inconsistency between the EESS and the review check-list with respect to temina'l block type and qualified life. It also states thatqualified.
| |
| equipment there is no traceability of the Hope Creek equipment to the correct the identified PSE&G has reviewed and revised the checklist to deficiencies.
| |
| Creek equipment is provided in BPC document E-1408. Assurance of traceability That document allows procurement of only the qualified teminal block models.

| |
| This document outlines the extrapolation of DBE test data for Buchanan Terminal Blockswith the use of the Arrhenius Relationship for Life Expectancy Cor.puter Program ( ARRHEN) .
| |
| This computer program was developed by Proto-Power Corpora-tion'for use in the determination of the expected life of !
| |
| : equipment subjected to thermal aging conditions. Details of the Buchanan Terminal Blocks expected life qualification are ;
| |
| ; provided in Section 4.0.
| |
| ; 2.0 ARRBENIUS RELATIONSEIP METHODOLOGY i
| |
| The accepted model for accelerated thermal aging testing is
| |
| ; the Arrhenius Relationship.
| |
| Typically, the Arrhenius-type formulation for relating life-
| |
| ! times at two temperatures is written as:
| |
| L 2 = eXp i . (Tt - T9)
| |
| : Li k TT2I where i e
| |
| T1 = Test temperature, degrees K
| |
| [ T2 = Service temperature, degrees K l L1 = Test time at temperature T 1 L2 = Expected Life at temperature T2 l
| |
| 7 = Activation energy, eV l k = Boltzmann's constant l
| |
| (0.8617 x 10-4 eV per degree K)
| |
| The units for L1 and L2 are consistent,in hours, days, years, etc.
| |
| 3.0 ARRBENIUS RELATIONSHIP COMPUTER PROGRAN 3.1 Description The program ( ARRHEN) calculates the life expectancy of equipment based on Arrhenius Relationship described in i
| |
| Section 2.0.
| |
| l From Reference 1 and 2, the source listing of the pro-gram, the base equation for calculating the expected i
| |
| life of equipment using the Arrhenius Relationship is:
| |
| EXPECTEDLIFEl = (E# ((ENERGY / BOLTZMANN #)*
| |
| j ((TEMP 1-TEMP 2)/(TEMPl* TEMP 2))))

| ARRRENIUS RELATIONSHIP FOR LIFE EXPECTANCY EXTRAPOLATION OF DBE TEST PROFILE This equation is a direct translation of the Arrhenius Relationship explained in Section 2.0.
| |
| A conversion factor of 8766 hours per year is used to convert the units of the expected life from hours to years. This factor is calculated as follows:
| |
| 365.25 day X 24 hours = 8766 hour year day year The 365.25 day / year factor is equivalent to an average year.
| |
| 3.2 Operation The Arrhenius Relationship program ( ARRHEN) is main-tained on and accessed via the Proto-Fower Corporation in-house personal computers. Authorized users may ac-cess the program for the purpose of evaluating the life expectancy of equipment subject to thermal aging.
| |
| 4 Access to the ARRHEN program is available through the Proto-Power Corporation working disk files.
| |
| A sample of the output is illustrated in Appendix A.
| |
| 4.0 EXTRAPOLATION OF DBE TEST PROFILE TO 100 DAYS Based upon test data supplied by the manufacturer, Reference 3, Figure 11, thg equipmept was subjected to temperatures ranging from 212 F to 346 F for 7 days. An activation ener-gy of 0.637 is obtained from Reference 3, Page A-6A. This report shows how the test egndition is equivalent to 300 F for 30 min, followed by 148 F for 100 days plus 10% time margin.
| |
| In grder to simplify calculations, Figure 11 is rgduced to 346 F for one hour (ollowed by two curves of 265 F for 95 hours followed by 212 F for 72 days. The equivalent life for these two curves is shown as follows:
| |
| Test Temp Service Temp Test Bours eV Equivalent Life 265 F 148'F 95 0.637 0.3729 212 148 72 0.637 0.0663 0.3729 + 0.0663 = 0.4392/ Years 0.4392 X 365.25 days = 160.4 days yr This is much greater than the 10% time margin required.

| : 2. Description of Observation: (continuation) this pressure drop for the following reasons:
| |
| : a. The pressure drops for the as-purchased valves (NVF001, HVF002 and HVF003) were not used even though the flow coefficients are shown in the calculation. The pressure drop for the as-
| |
| . purchased flow limiters was not used.
| |
| : b. The pressure drop across the venturi flow limiter was assumed j to be 10% of the maximum differential pressure drop.
| |
| The maximum calculated pressure drop per FD-1(Q) is 14.72 psi based on the conditions in Mode B of Figure 6.3-3 of the FSAR. The maximum pressure drop of 15 psi may be exceeded if the actual pressure drops from the as-purchased valves and venturi flow limiter are used.
| |
| I
| |
| : 4. Recommendation for Resolution (optional) : (continuation)
| |
| : b. BPC should provide assurance that as-purchased pressure drop data has been considered and incorporated where pressure drop parameters are critical to meeting system design requirements.

| l Response to Recommendation for Resolution l
| |
| , 4.a Calculation FD-1(Q), Rev. 2, is considered conservative, with a l correct result showing that the maximum calculated pressure drop i does not exceed the 15 paid maximum permitted pressure drop re-i quired by GE, and the venturi will limit flow to 425 lbs/sec. in 4
| |
| the event of a pipe break outside containment, as committed to in the PSAR.
| |
| Calculation FD-1(Q), Rev. 2, considered the as-built condition and revised references. When this revision was made, a different but internally consistent set of L/D values was used. The L/D
| |
| ! values used in each revision are technically acceptable. Table 1, i attached to this response, provides a summary example of the L/D
| |
| ! values used for fittings in each revision. It can be seen that although the gate valve L/D values used in revision 2 (taken from Cameron Hydraulic Data, 15th Edition, which is based on Crane .
| |
| Technical Paper No.410) are less conservative than the revision 1 values calculated from the manufacturer's Cy, all other values are i more conservative. The total L/D used in revision 2 is more con-servative than the total from revision 1.
| |
| The pressure drop across the venturi used in the head loss cal-
| |
| , culation has bee'n confirmed on vendor drawing 10855-J425-2-10,
| |
| ! and is shown on the drawing as the maximum unrecovered head loss
| |
| ! at design conditions f 1.12 psid (not to be confused with the pressure drop seen at the venturi pressure taps, which is con-siderably higher).
| |
| 4.b The calculation results are conservative and meet design require-ments. As a clarification and to avoid future confusion, the por-tion of Calc. FD-1 which refers to gate valve L/D values based on vendor Cy will be deleted by July 12, 1985.
| |
| ; 1 As described in 4.a above, the analyst chose an alternate method of calculating L/D values for the entire piping run in revision 2 i of this calculation. This method resulted in more conservative.
| |
| : results and is considered an acceptable method for calculating
| |
| , piping system pressure drops, instead of~using the as-purchased i pressure. drop values. The approach used on all pipe-system pres-i sure ' drop calculations is to use conservative, yet realistic L/D
| |
| ; values to provide assurance that system pressure and flow require-i ments are met.

| |
| . allow breaker closing for fast transfer conditions (Terminal 101);
| |
| slow transfer closing can occur irrespective of the position of Switch 52-CSS. That is, 52-CSS provides a permissive interlock for the logic from Terminal 101 only. The schematic diagrams indicate that Switch 52-CSS must be in the " Normal" position to allow breaker closing for either slow transfer (Terminal 101) or fast transfer conditions (Terminal 11). That is, 52-CSS provides a permissive interlock for the logic from Terminals 101 and 11.
| |
| : 3. Significance of Observation: (continuation)
| |
| Had the schematic been developed per the logic diagram, all four electrical channels and all eight offsite breakers (i.e., two per channel) would have been susceptible to spurious operation due to a fire in the room containing the logic cabinets for all four channels. The fire' hazards analysis for this room (FSAR Table 9A-145)' indicates that transfer cwitches allow one' train of safe shutdown equipment to be isolated from the control' equip-ment room.. Switch 52-CSS serves this' isolation function. Per the logic diagram it would not have served the function to allou one train of safe shutdown equipment to be isolated from the contrG equipment room. ,

O Date 6/13/85 (Continuation sheet) R/CR No.87 Rev. O Date G/pchrf Following is our response to the recommendation for resolution:
| |
| 4.a Based upon an extensive review of schematics for all eight of f-i
| |
| ' site breakers associated with all four Class IE electrical chan-nels, it is concluded that these schematics were developed cor-
| |
| : rectly to reflect the intended logic. None of the four electrical channels would have been susceptible to spurious operation due to a fire in the room containing the logic cabinets for these chan-nels. In accordance with the schematics, the transfer switch 52-CSS will serve the purpose of isolating the respective elec-
| |
| , trical channels (all trains) from the control equipment room.
| |
| 4.b There is a drafting error in the logic diagram E-3060, revision
| |
| : 10. Revision 11 to this drawing shows the 52-CSS (contact 19-20) signal correctly (CCN 0282491 dated May 10, 1985 transmitted copy to S& L) .
| |
| 1 4.c As stated in 4.a above, an extensive review of schematics for all eight of fsite breakers associated with all four Class IE electrical channels showed that they were developed correctly to reflect the intended logic. In order to further assure ourselves, logic diagrams and schematics were reviewed for all four emergency diesel generators and for one each (Channel B) of the SACS and SSWP break-ers. This review resulted in no discrepancy between logic diagrams and schematics. Since no errors were uncovered, a review of all logic and schematic diagrams associated with all equipment required for one train of safe shutdown equipment is not required.

O Date 6/18/85 (Continuation sheet) R/CR No. 9 2 Rev. 0 Date s/arbr e 2.a DITS D5.12 is a design document which specifies the design of the
| |
| ' Remote Shutdown System (RSS) as committed to in the FSAR.
| |
| DITS D5 12'and D3.10 together meet the requirements of the FSAR for the SACS system. DITS D5.12 was issued to consolidate the RSS requirements of the appropriate systems. RSS is a system in itself. We elected .to identify RSS requirements in DITS D5.12 and not in each specific DITS related to the systems that are part of the RSS.
| |
| 2.b DITS D5.12 states that indication for valves HV-2496B/D is provided on the Remote Shutdown Panel (RSP). Logic diagram J-11-0, Sheet 8, shows that control and indication for valves HV-2496B/D are pro-vided on the RSP.
| |
| The design as shown on the logic diagram is correct. DITS DS.12 will be revised to state that the RSP has provisions for control 1
| |
| and indication of valves HV-2496B/D.
| |
| August 15, 1985. The DITS will be revised by 4
| |
| 4.a Refer to response to 2.a and b.
| |
| 4.b.
| |
| DITS D5.12 was reformatted and revision 1 was issued on April 10, 1985. This revision inadvertently omitted the control design requirements for valves HV-2496B/D. The design of valves HV2496B/D shoen on logic diagram J-ll-0, Sheet 8, was correctly
| |
| # reflected in Revision 0 of DITS D5.12, Section 2.2.1.2.a, issued on July 27, 1982. The DITS required control as well as indication provisions on the RSP. Attached is page 12 of DITS D5.12, Revi-sion O.
| |
| We feel that this error is an isolated case. However, we will review revision 1 of DITS D5.12 against the applicable logic diagrams to ensure that identified in OR-92. The there are no other similar errors as j 1985.
| |
| review will be completed by July 12,
