EXECUTIVE SUMMARY Brunswick Steam Electric Plant. Units 1 & 2 NRC Inspection Report 50 325/97 13. 50-324/97-13 This integrated inspection included aspects of licensee operations, engineering, maintenance, and plant support. The report covers a 6-week period of resident inspection; in addition. It includes the resu'ts of maintenance, engineering, and fire protection ir,pections by regional and headquarters inspector Operations e The inspector concluded that u.e cold weather program has been satisfactorily implemented. Adequate contingency plans and operator checks for proper operation of the systems were noted in the procedure Section 01.1).
- The inspector concluded. from a safety system walkdown, that the Containment Atmospheric Dilution system was being maintained as designed (Section 02.1).
- The clearance reviewed was prepared. authorized, and implemented in accordance with procedure (Section 02.2),
e The inspector concluded that the Plant Nuclear Safety Committee meeting provided an effective review of Unit I readiness for restart (Section 07.1).
e Inspe.; tor review determined that clearance records were not retained in accorcance with Technical Specifications (TS). The failure to maintain clearance records in accordance with TS was a violation (Section 07.2).
- The control of a short duration mid-cycle o:tage was excellent (Section 07.3).
- Licensee investigation determined that removal of the IB Reactor feedwater Pump at too high a power level caused larger than expected level transients. These transients combined with the improper functioning of the level contacts in the Reactor Recirculation Run back logic circuitry, resulted in the November 5-6. 199/ run backs (Section 08.3).
- The inspector concluded that the licensee's control of the 2C and 20 electrical bus maintenance was weak because they did not recognize DG in oberabilityconditionsduringtheimplementationoftt.eirclearance ( ection 08.4).
F *
2 Maintenance e Movement of the spent fuel shi) ping cask was perforrxo in accordance with methodology approved by t1e NRC in a letter dated December 2, 199 Adequate supervisory oversight was present during movement of the cask (Section M1.1).
- The inspector observed performance of calibration of two Reactor Core Isolation Cooling (RCIC) pressure switches. The work activities were completed without any identified questions or concerns (Section M1.2).
- Maintenance activities observed relating to equipmert qualification of electrical equipment were found to be conducted in a thorough and effective manner (Section M1.3).
. A violation was identified for a preventive maintenance procedure not indicating specific E0 requirements. This omission resulted in deficient Nelson flame seals in motor control centers not being detected during scheduled preventive maintenance activities (Section M1.3).
- The licensee continues to struggle with proper dispositioning of abnormal indications. The failure to maintain the Daily Surveillance Report in accordance with procedure was a violation. Abnormal values observed fer the Steam Jet Air Ejector radiation monitor and subsequent test indicated potential fuel failure for Unit 1 (Section M3.1),
- The licensee identified that the Unit 2 Core Spiay sparger differential alarm setpoints were outside of the TS allowable range. The cauce was attributed to voiding of the sparger nozzles similar to the phenomenon identified previously on Unit 1. The alarm setpoints were adjusted and the associated documentation was updated (Section M8.5).
-Engineerino >
+ An additional example of a violation was identified for an inadequate procedure for the conduct of E0 maintenance (Section E1.4). Two inspector followup items were identified to review revisions to instrument setpoint procedures and to review terminal block leakage current evaluations (Section El.1 and Section E1.4).
- A weakness was identified regarding a procedure reference to a drawing for accident temperature data which was not available for use and wording inconsistencies in the procedure (Section E1.1).
- The licensee was making progress in resolution of the technical issues and closure of CRs and JCOs (Section E1.4). The licensee training and qualification for E0 personnel meets NRC requirements (Section E5.1).
Instrument setpoint calculations were technica ly adequate and complied with NRC requirements (Section E1.2).

Corrective maintenance on degraded fire protection systems was i
!
accomplished in a timely manner. The maintenance and material condition of the fire protection equipment and features were satisfactory (Section F1.1).
. The inspector concluded that silicone foam penetration seal field verificction documentation was maintained by the licensee. The inst 311ation and repair procedures for penetration seals provided adequate guidance to ensure that materials were installed per design requirements. However, the designs were not supported by seal testing documentation, vendor data and inspection criteria, installer qualification and training records, and engineering evaluations that satisfy the guidance of Generic Letter 86-10 for deviations from the fire barrier configuration qualified by tests (Section F2.2).
.
The inspector concluded that fire door surveillance procedures and acceptance criteria for verification of fire door clearances were in accordance with National Fire Protection Association (NFPA) guidanc However, an updated Final Safety Analysis Report (UFSAR) discrepancy associated documentation of fire door and frame evaluations was identified (Section F2.3).
. General housekeeping was satisfactory. Fire retardant plast.ic sheating and film materials were being used. Lubricants and oils were properly stored in approved safety containers. Controls for combustible gas bulk storage and cutting and welding operations were being enforce Controls were being properly maintained for limiting transient combustibles in designated separation zones and other restricted plant areas (Section F3.1).

~ Summary of Plant Status Unit I returned to power o)eration on November 14. 1997, following a mid-cycle outage that began on Novem)er 5. 1997, to remove leaking fuel assemblies. Two leaking fsel assemblies were identified and removed during the mid cycle outag However, indications of a potential fuel leaker remained after the unit returned to full power operation. At the end of the report period the unit had been on-line 42 day Unit 2 operated continuously during this report period. At the end of the report period the unit had been on-line continuously for 59 day Due to concerns about the control room dose, the licensee imposed an administrative limit on lodine until a Technical Specification (TS) amendment submitted was a) prove The licensee made a orocedure change to Administrative procedure 0Al-81. Water Chemistry Guidelines, setting the limit at 0.1 microcurie per gram dose equivalent L 'ine 131 compared to the TS value of 0.2 microcurie per gram. Also, the licet ;e has been providing weekly water chemistry data to NRR and the Resident Inspector for review. None of the data reviewed has exceeded the administrative limi Due to a reconstitution of the Environmental Qualification (EO) program and items identified, there are 12 of 24 Justification for Continued Operation (JCO) that remain open for both units.

weather. heat trace installed. The inspector determined that the operation of the Makeup Water Tank system heat trace was not controlled by any procedure. The licensee stated that this heat trace system was being controlled b," operator knowledge only. The licensee initiated a procedure change request to place this heat trace system into their cold weather procedures. The inspector noted on the Unit 2 Condensate Storage Tank. High Pressure Coolant Injection (HPCI)/ Reactor Core Isolation ~ Cooling (RCIC) level switch vent line that a six inch portion of the lagging was missing at the top of the vent line and that the tin shielding was missing around the lagging at an elbow on the vent lin The lagging was wetted and degraded at the elbow. The inspector discussed these two items with the licensee. The licensee did not warrant these deficiencies as requiring corrective action. The inspector did not find other systems requiring heat trace that were not heat traced based on present system conditions and projected use of the systems observe Conclusions The inspector concluded that the cold weather program has been satisfactorily implemented. Adequate contingency plans and operator checks for proper operation of the systems were noted in the procedure Operational Status of Facilities and Equipment 02.1 Containment Atmosoheric Dilution (CAD) System Walkdown
.
' Insoection Scope (71707)
On December 10. 1997, the inspector performed a walkdown of the CAD system in the Nitrogen and Off-Gas Services Buildin Observations and Findinos The CAD system is described in Updated Final Safety Analysis Report (UFSAR) Section 6.2.5. Combustible Gas Control in Containment. The CAD system provides long-term nitrogen makeup after a Loss of Coolant Accident (LOCA). This function is accomplished by vaporizing liquid nitrogen and feeding it into containment as required to maintain an oxygen concentration at or below five percent. The system is designed to Engineered Safety Feature (ESF) standards, all equipment for CAD service is designed with suitable redundancy and interconnections such that no single failure of an active component will render the system inoperable. This equipment includes one liquid nitrogen storage vesse two electric vaporizers, two flow-regulating stations. flow and temperature indicators. and appropriate redundant valves and interconnecting pipin The inspector traced the system piping in the Nitrogen and Off-Gas Services Building. The configuration was compared to plant drawing 0 02560. Containment Atmospheric Control System. The configuration was found to be like the plant drawing. The inspector observed an inch of

frost on the outside of the piping insulation on both sides of valve HV-1 This valve is a manual isolation between the nitrogen tank and an 85 pound pressure regulating valv The inspector questioned why the frost was on the line. The licensee stated that the 90 pound relief valve setpoint was near the controlling pressure of the 85 pound regulator and some nitrogen was venting of The redundant pressure regulating valve was isolated and it's isolation valve (HV-12) was closed. The inspector questioned by keeping HV-12 closed, if the system was single failure proof. The licensee initiated CR 97-04128. CAD Tank Isolation Valve, to address this issue, The licensee concluded that no automatic action was required to address a LOC Manual alignment of the pressure regulator was acceptable since this was a long term post-LOCA actio Conclusions The inspector concluded, from a safety system walkdown, that the CAD system was being maintained as designe .2 Clearance Verification l Insoection Scoce (71707)

07 Quality Assurarm in Operations 07.1 Restart Plant Nuclear Safety Committee (PNSC) Insoection Scone (71707)
On November 11 and 12. 1997, the inspector attended the Unit 1 PNSC restart assessment following a mid-cycle outage to replace two leaking fuel assemblies, Observations and Findinos On November 11, 1997. PNSC was convened to review Unit I readiness for restart. The committee reviewed the fuel sipping results and core reloa Other maintenance activities during the outage were also reviewe The meeting was conducted in accordance with TS with attendance by all primary members, with no alternates. The meeting provided a thorough discussion of all agenda items. The PNSC Chairman concluded that the discussion of recirculation pump runbacks that occurred on November , during removal of the reactor feed pumps during the planned shutdown was not complet This item was statused as a restart constraint requiring another PNSC review prior to restart. Noteworthy in the review was the risk assessment review conducted for a failed Control Rod Drive (CRD) pump. During the mid-cycle outage one of the two CRD pump motors failed. The Probabilistic Safety Analysis (PSA)
person attended the comnittee meeting and presented the results from running the risk assessment model considering failure of both CRD Jump This risk was determined acceptable based on other TS required higi pressure injection sources such as HPCI and RCI On November 12. 1997, the inspector attended a second meeting. In this meeting discussion was held regarding the problem with run backs and it was concluded that this was due to a design deficiency that was already corrected and installed on Unit 2 and scheduled for Unit 1 at the time of the next refueling outage, Conclusions The inspector concluded that the PNSC meeting provided an effective-review of Unit I readiness for restar .2 Retention of Clearance Records Insoection Scope (71707)

6 Observations and Findinas During ins)ector review of clearance errors which resulted in damage to the Unit 23 recirculation pump seals, the licensee was unable to locate a clearance hung to facilitate repairs on the recirculation motor oil- -
cooler. Tha clearance. 2-97-1531. was hung _resulting in a configuration change for the B recirculation pump, but no maintenance on the system was performed. The clearance was removed from the field, thus restoring the system, and " rolled back" to allow use at a later dat Subsequently, a scheduler requested the clearance be deleted due to the repair activities being complete and approved without need for the clearance boundary. As a result of the deletion of the clearance, no record of the change in plant configuration was retaine The inspectoi : viewed TS 6.10. UFSAR Section 1.8. Regulatory Guide 1,88, and ANS1 N45.2.9-197 fhe inspector questioned the correctness of not retaining the clearance. Since a configuration change did occur despite the recirculation motor cooler activities not needing the cooler isolated. Nuclear Records Management Procedure ORMP-001. Indexing of Plant Records. defined those records required to be retained to satisfy the 0A requirements stated in ANSI N45.2.9-1974. Discussion with the licensee revealed that the records required to be retained did not include clearances. The inspector reviewed the Nuclear Generation Grou)
Standard Procedure OPS-NGGC-1301. Equipment Clearance, and the Brunswicc Required Records Lis Neither document required that clearances be retaine TS 6.10 requires facility records shall be maintained in accordance with ANSI N45.2.9-1974. ANSI N45.2.9-1974, in Section 3.2.7. Retention of Records. states that Appendix A to the standard defined the types of 0A records and the recommended retention periods. The failure to maintain data sheets or logs on equipment alignment consistent with ANSI N45.2.9-1974 is a violation. This violation is identified as VIO 50-325 (324)/97-13-01. Failure to Retain TS Required-0A Recor Conclusion Inspector review determined that clearance records were not retained in accordance with TS. The failure to maintain clearance records in accordance with TS was a violation.
07.3 Mid-Cycle Outaae (71707) Insoection Scope The inspector reviewed the mid-cycle outage activities to remove the leaking fuel assemblie Observations and Findinas Unit 1 was returned to power operation on November 14. 1997. This completed a mid-cycle outage in eight days. The unit was shutdow _-

leaking fuel assemblies identified, removed, fuel reloaded and returned to power o)eration. This short duration outage was the quickest on record. T11s was accomplished with plant personnel without any major problems. This outage was planned and controlled similar to a regular refueling outag c. Conclusions The control of a short duration mid-cycle outage was excellen Miscellaneous Operations Issues (92700, 92901)
08.1 (Closed) Unresolved Item (URI) 50-325/96-15-01: Vessel Disassembly Without Secondary Containmen During a refueling outage, the reactor vessel head and steam dryer /separatorr assemblies were removed from the reactor vessel without secondary containment integrity (SCI) established. This issue was reviewed by the NRC Office of Nuclear Reactor Regulation. It was determined that the removal of the nead and assemblies without SCI established were not activities prohibited by TS 3.6.5.1. The potential

'
by the NRC. However, maintenance of SCI curing vessel disassably was a logical extension of the defense-in-depth ap3 roach used in addressing the heavy loads issue and encouraged by the 4RC. The licensee's action in proceeding with vessel disassembly was not conservative. The licensee implemented controls during the Unit 2 refueling outage to maintain secondary containment operable during vessel disassembly. This issue was thoroughly evaluated as part of the licensee's Safe Shutdown Risk Management Assessmen .2 (Closed) Violation V10 50-325(324)/97-02-01: Locked Valve Out of Position The licensee's response to this violation was dated May 5, 1997, and was accepted by the NRC in a letter dated May 23. 1997. The corrective actions described in the response letter were verified as complete by the inspector. This violation is close .3 (Closed) URI 50-325/97-12-03: Recirculation Pumo Run backs On November 5. 1997, the licensee began a c0ntrolled shutdown for the Unit 1 forced outage in order to replace leaning fuel bundles. During the shutdown. Unit I received two recirculation pump run backs to the 45 percent limiter. During the second run back the five percent buffer region was entered and exited in accordance with procedures.
) Subsequently. no other transients or run backs were ercountered while removing the Reactor Feedwater Pumps (RFPs) from service. The licensee preliminarily attributed the first run back to a malfunction of the 1B discharge check valve causing diversion of the 1A RFP through the 1B discharge valve to the main condenser. The final analysis was provided in the root cause analysis for CR 97-3917. Unit 1 Plant Transients While

Removing a Reactor Feed Pump from Service. The inspector reviewed the analysis and noted that the root cause attributed the run backs to the removal of the RFPs at too high of a power level and a design problem in the a) plication of the Metal-On-Silicon Field Effect Transistor (MOSFET)
switcl. The MOSFET was used in the 45 percent recirculation pump run back logic to indicate the below 182 inches reacter water level contact which is one of two contacts required to initiate the run bac Reactor water level perturbations are expected during the removal of the RFPs from service: however the magnitude of these perturbations seen for these events were outside of the operators expectations. The root cause analysis stated that removal of the RFP at 65 percent power was inappropriate in that 65 percent during this evolution has changed since power uprate. Before power uprate. RFPs were removed from service 3er 10P-32, Condensate and Feedwater System Operating Procedure, at or )elow 65 percent. Under current conditions 65 percent is approximately equivalent to 68 percent power pre-uprated power. The analysis attributed the magnitude of the perturbations to removal at too high of a power level. In addition, the licensee determined that when the first RFP was taken out of service, the less than 20 percent RFP flow contact for the 18 pump was made up and with the MOSFET improperly indicating below 182 inches water level the run backs were received. The design of the MOSFET causes the contact to not be able to properly position itself u'aon loss of the constant voltage supply. Therefore interruptions in tle voltage will cause the MOSFET contact to not function as designe The second Run back was also attributed to the MOSFE The licensee intends to replace the MOSFETs in the next Unit 1 outage, The inspector noted that the MOSFETs had already been replaced in Unit The licensee is reviewing plant operation to determine the appropriate power level for removal of the RFPs from service. Based on licensee satisfactory comaletion of the investigation into the cause for the multiple run bac(s on November 5-6, 1997 this item is close .4 (Closed) URI 50-325(324)/97-12-04: Diesel Doeration Low Voltace Auto Start Defeated The inspector reviewed the licensee's root cause investigation CR 97-03683, 4KV Bus 2C/2D Clearances. The licensee's investigation determined that the number 3 diesel generator (DG) undervoltage relay had been disabled in the same manrer as the number 4 DG during similar maintenance activities on different day The inspector verified that the licensee did not exceed TS action, limiting condition for operation, or time requirements for both electrical bus maintenance activities. The inspector found that, on October 9. 1997, the plant was under a TS action statement requirement per TS 3.8.2.1. to restore the inoperable bus to operable within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />, or be in hot shutdown within the next 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

be adequat The ins)ector concluded that the licensee *s control of the 2C and 2D electrical aus maintenance was weak because they did not recognize that the DG would be inoperable during the implementation of their clearance. This item is close II. Maintenance M1 Conduct of Maintenance M1.1 Spent Fuel Cask Movement a. Inspection Scooe (62707)
The inspector observed transfer of the spent fuel shipaing cask from th foot elevation to the transport v'hicle and from t1e transfer vehicle to the 117 foot elevation of the Unit 1 Reactor Buildin s b. Observations and Findinas On December 8. 1997, the inspector observed the removal of the spent fuel shipping cask, with fuel in the cask from the 117 foot to the 20 foot elevation in the Unit 1 Reactor Building. On December 15, 1997, the inspector observed shipping cask movement, without fuel in the cask, from the 20 foot elevation to the 117 foot elevation in the Unit 1 Reactor Building. During both evolutions the cask was transferred with the valve box covers removed while being moved by the non-single failure proof yoke. Approval for use of a non-single failure proof yoke for movement of the cask with the valve covers removed was granted to the-l licensee by the NRC in a letter dated December 2, 1997. Upon reaching the transfer vehicle on December 8. 1997. the cask was wiped down to reduce contami.1ation levels. During both movements the inspector noted that the area was adequately posted for the radiological conditions I present and i ealth pnysics personnel were present. The inspector noted that adequate maintenance supervisory oversight was present for both cask movement Subsequent surveys of the cask after removal from the Reactor Building revealed that the shipment exceeded required limits. This event was captured in CR 97-4161. S)ent Fuel Cask (IF-300). The cask was returned to the Reactor Building w1ere additional decontamination was conducte The licensee attributed the contamination levels seen to leaching of the contamination due to changing temperatures and weather condition c.

The inspector observed the performance of Maintenance Surveillance Test 2MST-RCIC230. RCIC Turbine Fxhaust Giaphragm High Pressure Instrument Channel Calibration, for the pressure switches 2-E51-PSH-N012A and 2-E51-PSH-N012 Observations and Findinas On December 24. 1997, with Unit 2 at 100 percent power the inspector observed the channel calibration for RCIC pressure switches 2 E51-PSH-N012A and 2-E51-PSH-N012 The inspector verified that duriug the performance of this channel calibration that HPCI and Automatic Depressurization System (ADS) were o)erable and that no othar work activities were being conducted whic1 could cause an inadvertent isolation. This test verified that, upon sensing of a high pressure condition between the t'arbine exhaust dia)hragms, an isolation signal is sent in accordance with TS 4.3.2.1 and Ta)les 3.3.2-2(4.b.6) and 4.3.2-1(4.b.6)
The inspector reviewed the work request / job order (WR/J0) AKNU 19 and the governing procedure 2MST-RCIC230. The procedure in use was verified to be the correct revision and the test instrumentation in use was within the allowable calibration duration. The inspector observed the

RHR Breaker Test in compartment DM 5 of GE IC 7700 Series MCC 2XB-2 Division Il Observations and findinos The above work was ,m cformed with the work packages present and in active use. Technicians were skillful, experienced, and knowledgeable of their assigned tasks. However, on December 10, 1997, while observing Instrumentation and Control (I&C) maintenance personnel perform work activities in accordance with WR/JO 97-AAAS-002, the inspector noted that one of the multiple cable electrical penetrations in the top of MCC 2-2XB-2 did not have Nelson flame guard putty on the inside surface as required by Maintenance Procedure OMMM 016. Environmental Qualification Maintenance Program. Revision 4. to properly seal the penetration. The inspector examined the putty installation on the top of the MCC cabinet for each of the penetrations and found the putty seal severely damaged on a second multiple cable penetration. In addition, cables were loose in both of the multiple cable penetrations. The applicable Environmental Otalification Data Package (ODP). ODP 67, requires missing or disturbed Nelson putty seals to be repaired or replaced. However, the PM procedure used to maintain and inspect the MCC's (PM Procedure OPM-MCC002. Revision 7. PM of GE Motor Control Centers and Switchboards)
did not have inspection requirements or acceptance criteria to ensure that putty seals were properiy sealing the cabinets. On September 17.
f 1997, a three-year PM conducted on MCC 2-2XB-2 would have identified l this discrepancy had procedure OPM-MCC002 included the acceptance criteria for the Nelson flame seal putty. A subsequent inspection performed on December 11. 1997 by the licensee, of 22 MCCs found an additional three MCC cabinet penetrations with damaged Nelson putty seals. In addition. 15 3ercent of the cables inspected in cabinet penetrations had putty w1ich appeared not to fully adhere to the cable in some areas. Failure of the procedure to implement E0 requirements for Nelson autty seals is identified as VIO 50-325(324)/97-13-0 Inadequate 3rocedure for the Conduct of E0 Preventive Maintenanc c. Conclusions Maintenance activities observed related to E0 of electrical equiament were found to be conducted in a thorough and effective manner, iowever, a violation was identified for a PM procedure not indicating specific E0 requirements.

Unit 1 was in mode 1 at 100 percent powe The inspector reviewed the daily surveillance report as contained in Attachment 1 to 101-03.1 for November 30 through December 1. 199 The inspector noted that the values for the Steam Jet Air Ejector (SJAE)
i off-9as radiation monitors on aage 26 were between 1570 and 1780 millirem per hour (mR/hr) whici was greater than the T3/ Operating Limit
- value of 1000 mR/hr. The SJAE off-gas radiation monitors provide for the detection of fuel element failures. The radiation levels are recorded in 101-03.1 to provide an indication whether SJAE off-gas radiation levels are approaching the alarm setpoint, which serves to ensure that dose rates for gaseous effluents do not exceed the limits l
prescribed in TS 3.11.2.1. Dose Rate.
l The inspector reviewed the associated procedures, work tickets, and discussed the abnormal values with the licensee. Step 4.2 c 'f 001-0 required the control operator to red circle all values wt are not within required limits. The inspector noted no indication on the attachment or in the operator logs that action had been taken or was expected to be performed to address the out-of-range values. Subsequent reviews of the daily log entries by the inspector indicated continual abnormal values and no red circle These failures were recorded in CR 97-4136. Daily Surveillance Repor The failure to red circle values not within required limits is a violatio This violation is identified as VIO 50-325/97 13-03. Failure to Note Abnormal TS Surveillance Value CR 97-4100. Questioned OG Data / Fuel Leak indicated that on December 3, 1997, a step increase of approximately 200 mR/hr was seen on the radiation monitor Subsequent sample results have shown an increase in the Sum of Six value ano changes in the fuel reliability index which are signs of potential fuel failure. In addition, the inspector noted that incorrect sensitivities were used during the November 25, 199 adjustment of the SJAE radiation monitor alarm setpoilts. This was documented by the licensee in CR 97-4046. SJAE Rad Mci. sensitivitie CR 97-4180 SJAE rad monitor setpoints, addressed coordination problems ',
between the Operations procedure used to request new radiation monitor setpoints, the Environmental and Radiological Control (E&RC) proced ce that calculates the new setpoint, and the Maintenance procedure that installs the new setpoints. By the time the radiation monitor setpoints were ready to be installed the new values needed to be recalculate The inspector determined as a result of the cited failure and the three additional CRs mentioned previously, that control and monitor'.ng of the alarm setpoint was poor. Previous instances of failing to properly disposition abnormal values were recorded by the NRC in Inspection Re) ort (IR) 50-325(324)/97-12, when inadequate corrective action was tacen for abnormally high drywell temperature.

Themfore. the licensee could not evaluate whether the alarm setpoint was within the " normal" TS range. This nonconformance resulted in VIO 50 325/97-05-02. Inadequate CS Surveillance Procedur The licensee performed reviews of data collected nonroutinely during 1995-1996 and in ESR 97-181 calculated a " normal" value for setpoint verification in the related surveillance procedures. The licensee subsecuently changed the alarm setpoints and updated the affected procec ures.

Rev. 3. dated August 26, 1997 The inspectors verified that the procedures provided adequate instructions for establishing, maintaining and implementing the requirements of'10 CFR 00.49 except for the issues discussed belo Section 9.6 of procedure EGR-NGGC-0156 provided the guidance for maintaining E0 qualification data packages (ODPs). The procedure specified that changes to ODPs are to be captured using the ESR process. The procedure required that ODPs were to be periodically updated as necessary to maintain auditability, to incorporate new
'
requirements, to meet plant specific requirements, ard to keep the number of outstanding-changes at a reasonable level. However
procedure EGR-NGGC-0156 did not specify a clear time requirement for updating the CDPs. The inspectors also determined that procedure EGR-NGGC-0007 did not provide any requirements for updating ODP The failure to s]ecify specific criteria in procedures could result in the 0)Ps becoming unauditable which is contrary to the requirements of 10 CFR 50.49. The failure to maintain and u]date the ODPs was one of the causes of the violation whic1 resulted in the civil penalty identified in NRC Inspection Report (IR) 50-325(324)/96-14. The failure to establish clear, definite requirements for updating ODPs was identified as a violation example at the Shearon Harris Nuclear Plant in NRC IR 50-400/97-12. Since all Brunswick 00Ps are being revised and updated at the current time, a violation was not identified for this issue during the current inspection.

Robinson plants use the same corporate EGR-NGGC ?,ocedure Procedure EGR NG D 0153 provides the methodology to establish instrument setpoint margins sufficient to account for various instrument uncertainties and environmental effects including temperature, pressure, radiation, seismic, and insulation resistance errors Although procedure EGR-NGGC-0153 provided guidance on the treatment of environmental effects, the inspectors noted that in the discussion of temperature effects, the applicability of vendor 3 worst case performance specifications to plant specific conditions i was not clear. The inspectors also noted that requirements for seismic effects in procedure EGR-NGGC-0153 were not clear regarding t6 match / confirmation of vendor profiles to plant specific [ les or configuration, in addition, the inspectors noted that procedure EGR-NGGC-0153 referenced Drawing 0-03056. Service Environment Chart Normal &
Accident Conditions. Units 1 & 2. for information on accident temperature data to be used in instrument setpoint calculation The inspectors determined that-Drawing D-03056 was " frozen" on December 12. 1996, and was not available for use. The reason for removal of Drawing 0-03056 from use was documented in CR 96-04002 which identif9d the need to revise. and update Drawing D-03056-to incorporate f icironmental data from the Reactor Building Environmentai Renort (RBER), Revision 5. The inspectors noted in review of calculations initiated since December 1996, the RBER was referenced for temperature profiles in the re:ctor buildin The licensee indicated that a revision to EGR-NGGC-0153 will be initiated to resolve inconsistency in wording regarding the application of accident temperature / seismic effects to make it clear that vendor test results would fully envelope site specific profiles unless an evaluation has been aerformed to evaluate the-differences. Additional guidance will 3e included to characterize the requirements for engineering reviews of test-data to ensure seismic and environmental profiles are bounding for site specific conditions. The licensee indicated procedure EGR-NGGC-0153 will also be revised to either remove D-03056 as the reference for temperature data and replace it with the appropriate reference (the RBER) . or to correct the drawin The inspectors also identified that procedure EGR-NGGC-0153 unde-Section 9.5.1.

Nuclear Reactor Regulation. Conformance to Regulatory Guide 1.97 Revision 2. Brunswick Steam Electric Plant. Units 1 and 2. Dated May 14. 1985. the inspectors concluded that these calculations were. typical. The instrument setpoint calculations typically considered 140 F as the maximum temperature in the calculation From review of the calculations, the inspectors determined that instruments that perform a safety function are analyzed for a LOCA environment in the reactor building. The calculations showed that instrument uncertainties considered instrument temperature effects for a maximum temperature of 140' F which is bounding for the analyzed LOCA environmen The inspectors also determined that instruments relied upon to mitigate the effects of a high energy line break (HELB) were also evaluated by the licensee. For this instrumentation, environmental uncertainties-for a harsh environment were not required to be considered since the instrumentation function would occur before the reactor building temperature )rofiles listed in p the Reactor Building Environmental Report (REBR) Revision dated November 5. 1997, would reach 140 F and affect instrument performance. The ins)ectors noted that abnormal temperatures were not discussed in the-RBER. Discussions with licensee engineers disclosed that the design base accident event is based on an initial building environment airspace temperature of 104 F. The building temperatures ace measured and recorded daily by plant operators in accordance with procedure numbers 101-03.4.1 and 201-03.4,4. Unit 1 and 2 Control Operator Daily Check Sheets.. The
= operators are required to contact the duty engineer when the reactor building temperature exceeds 104 F so that engineering can perform an assessment of the effects of temperature on environmental qualificatio The inspectors noted that calculations for instrumentation which mitigates a HELB demonstrated that the instrument and associated equipment would not be exposed to a harsh environment before the instrumentation performed its safety function. In the instrument calculations reviewed by the inspectors instrument setpoints were based on a maximum temperature of 140 F (non-steam environment).
Although allowances were not made for a harsh environment. a seismic allowance was included in the calculation Review of the temperature profiles as shown in the Brunswick Reactor Building Environmental Report showed that the actuation isolation signal would occur before exceeding the temperature allowances assumed in the setpoint uncertainty calculations. An exce) tion was the High Pressure Coolant Injection (HPCI) line breat in the steam tunnel where the temperature profile showed that 140 F would be exceeded for ap3roximately 2.5 seconds before the isolation trip _ signal occurs. iowever this instrumentation would remain operable based on thermal delays. However, the HPCI isolation function would most likely be initiated by temperature
.
sensors in the steam tunnel or HPCI room which would occur imediately with no time dela The inspectors concluded that the instrument setpoint calculations complied with NRC requirements and were technically adequat Review of the calculations showed that environmental effects, j- specifically accident temperature, were correctly evaluated in the calculations, Conclusions The inspectors concluded that the licensee's calculations were technically adequate and complied with NRC requirement The inspectors concurred with the licensee's conclusions that the setpoints for instruments relied upon to mitigate the effects of a KLB did not require inclusion of uncertainties for a harsh environment since the instruments perform their ft..iction before being effected by the harsh environment. Setpoints for instruments required for LOCA effects include the appropriate environmental uncertaintie El.3 Enaineerina Service Reaucst (ESR) 97-00426 Inspection Scoce (375501 '
The inspectors reviewed ESR 97-00426 which was prepared to address questions on instrument setpoint Observations and Findinas A review of procedures and various documents by an independent consultant resulted in questions involving environmental effects including uncertainties on instrument accuracy. These guestions .
were dccumented in an E-mail message dated June 20, 1997 Subject: '
E0 and Instrument Accuracy. The licensee addressed the referenced !
memo in Engineering Service Request ESR 97-00426. Revision dated September 18. 1997. ESR 97-00426 documents the evaluation completed by the licensee to address environmental effects on-instrumentation. The inspectors noted that the licensee response did not address the questions in the June 20, 1997 E-mail message point by point. but provided an evaluation that was more generic in nature. The inspectors noted that ESR 97-00426 was an engineering disposition (ED) type ESR. as defined in procedure EGR-NGGC-000 The use of this type ESR to respond to the E-mail cuestions was appropriate since the ESR only communicated existing cesign requirements, did not produce design output, and did not change existing engineering document The ESR concluded that instruments that aerform a safety function are analyzed for a LOCA environment in t1e reactor building. The instrument uncertainties consider -instrument temperature ef fects for a maximum temperature of 140"F which is the maximum bounding

The licensee stated that they will correct this error when the ESR is revised. as discussed belo ESR 97-00426 also concluded that harsh environmental effects have been appropriately accounted for in safety related uncertainty calculations. The ESR concluded that the isolaticr. aquence for a HELB due to main steam line break. reactor core isolation cooling l steam-line break, high pressure coolant injection steam line break, cr a piping failure in the reactor water cleanup system is such thtt the isolation function will occur before the instrumentation is exposed to harsh environmental effects. This conclusion was based on the instrumentation being able to perform its safety function prior to the temperature exceeding the temperature allowance assumed in the setpoint calculations. For area temperatures exceeding the setpoint temperature uncertainty allowance, the use of emergency operating procedures (EOPs),

The inspectors reviewed the licensee's corrective actions for the
Environmental Qualification (FO) program, in response to findings l identified during Self-Assessment numbers 95-0041 and 96-0271 and the violations identified in NRC IR 50-325(324)/96-1 Observations and Findinas 1) Review of E0 Equipment Data Base The licensee's corrective actions to resolve the discrepancies in the E0 program identified by NRC (See IR 50-325 324/96-14)
include corrections to and updating of the Equipment Data Base System (EDBS). Numerous errors in EDBS had been identified and corrected by the licensee since the inspection findings were identified in IR 50-325(324)/96-14. The errors in EDBS were .
identified during E0 equipment walkdowns and review of various !
data bases. In addition, numerous errors were identified in the EQ zones listed in EDBS for the location where various components were installed. These primarily occurred at. zone boundaries and were being resolved during review of walkdown dat The requirements for. recording and correcting E0 data in EDBS was s)ecified in- CP&L procedures EGR-NGGC-0156 and ENP-33, The-c1anges to EDBS to correct errors were processed using Form 100 of ENP-33.6. The Form 100 was design verified in the E0 unit and was then forwarded to appropriate personnel for entry into EDBS. All EDBS data entries made were independently verified by personnel in the Configuration Management group in the Design Control Uni The independent verification was performed to minimize o-eliminate data entry errors. Additional corrections to EDBS were ongoing to incorporate E0 walkdown ins)ection results and the revisions to EQ qualification data paccage The inspectors reviewed some randomly selected revisions to EDBS identified as a result of the E0 corrective actions and verified the EDBS data had been corrected. The inspectors also discussed the program for control of changes to EDBS with various licensee personnel who perform the day to day system revisions. These

" Qualification Data Package For NAMCO EA180 Series Limit Switches" to determine if it adequately demonstrated environmental qualification for the safety related NAMCO switches for use inside the drywell in accordance with 10 CFR 50.49 and appropriate licensee E0 Prccedures. The package addressed the following:
qualification level (0588 Cat. I); tag numbers of equipment covered in the QDP: test report aaplicability; similarity of test specimens to installed equipment: E0 parameters. temperature, pressure, relative humidity, radiation, chemical spray, submergence; cualified life: E0 maintenance requirements; test anomalies; anc operating experience item During review 3f the Draft ODP. the inspectors identified the following questions / comments:

- In Section 2 of the 00P it was stated that it was a good maintenance practice to lubricate the NAMCO limit switche however. lubrication was not specified in Section 4 of the ODP which lists recommended maintenance practices.
In Section 4.2 of the ODP it was stated that the switches can be refurbished. However, a statement was made on page 21 that qualified replacement part kits were no longer available.
- A reference was made to abnormal temperatures on page 38 of the OD However, abnormal temperatures were not included in DR 227.
- The inspectors questioned apparent inconsistencies between activation energies and aging methods discussed in referenced qualification test reports (OTRs).
The licensee indicated that these comments would be evaluated by the E0 group and if appropriate, addressed in Revision 4 of the QDP when it is completed.
The inspectors reviewed a draft copy of Revision 7 of ODP-67 General Electric Company IC 7700 Series Motor Control Centers for BN The GE MCCs. located or, the 20, 50, and 80 foot elevations of the Units 1 and 2 Reactor Buildings, are subject to harsh environments resulting from postulated design basis accidents and ;

A series of similarity analysis were performed to demonstrate similarity between the tested configuration and supplied. The inspectors reviewed portions of DR 232. "Nutherm Report No. CPL-7806R. Qualification Test Results Applicable to Brunswick Nuclear Power Plant Safety-Related GE 7700 MCCs." Revision 0, dated June 30, 1997 which dccumented the similarity analysis. Section 2 of DR-232 contains a discussion on the similarity analysis between the components tested by NUTHERM and those installed in the Brunswick MCCs.
The similarity discussion covers fuses, stab assemblies, control transformers control and power wiring, overload heaters. overload relays, terminal boards, starters and contactors, molded case circuit breakers. circuit protectors. disconnect switches. potentiometers, and indicating lights. The similarity analyses were based on the similarity analyses contained in DR 1.1. GE Company NEDC-30696-P. May 1985. MCC Oualification Test Report Phase Il for CP&L Brunswick Plant, or were devices which could be directly linked to a test specimen and did not require a similarity analysis. Based on review of DR-232 NRC concluded that NOTHERM was able to establish that the com3onents they tested were in the same family as those provided by GE in t1e MCCs. This review was also dccumented in IR 50-325(324)/97-0 A draft copy of Revision 0 of ODP 99. R. G. Laurence Series 500 and 600 Solenoid Valves was reviewed.

3) Review of EO Walkdown Data The inspectors reviewed E0 walkdown data which document inspection of E0 equipment-in the Unit 2 MSIV pit and drywell, and Unit 2 reactor building. Tha E0 walkdowns were performed in accordance with CP&L Special Procedure OSP-96-014. EQ Equipment Field Verification. The pyrpose of the walkdowns was to verify the accuracy of the manulacturer/model number listed in the licensee's data bases and to verify the equipment installed orientation and configuration were in accordance with the E0 qualification documentatio The ins)ectors reviewed walkdown records for scram '
pilot' solenoid valves, 1AMC0 limit switches, temperature elements, excess flow check valves, and pressure switches. The walkdown data was recorded on field inspection data sheets which were'then converted into an electronic data base. The inspectors verified that discrepancies identified during the walkdowns were documented either on a work request (WR/J0) for repair, or in a condition re) ort (CR). The ins)ectors reviewed completed WR/JO numbers 97-AF JR1, 97-AFUR2, 97- A UR3, and 97-AFUR4. These WR/J0s document drilling of weepholes in junction boxes in the Unit 2 MSIV pit to resolve a moisture intrusion issue. These boxes are associated
.
with limit switches for the Unit 2 main steam isolation valves.
L The completed WR/J0s showed that the weepholes were drilled to resolve the concerns. The inspectors did not identify any
- discrepancies in the records reviewe ) Review of Environmental Qualification Condition Reports The inspectors reviewed the licensee's corrective c.,ctions to L disposition the CRs listed below. These CRs were initiated by the licensee to-document and disposition nonconforming items whicn were identified during the ongoing E0 reconstitution project. The nonconforming items were identified as a result of E0 equipment walk h ns, review cnd updating of E0 equipment ODPs, omissions from the original program, or changes to the operating environment. The CRs reviewed were as follows
CR 97-02015 The licensee initiated CR 97-02015 on June 6. 1997 to document and disposition deficiencies that had been identified by the licensee's training staff during observation of simulator training when the fire protection system had not been isolated within the 15 minute time period after initiation of a HELB specified in 31 ant o)erating 3rocedures. The 15 minute time period is the

assigned to the Operator Training group to incorporate the basis
,
for the need to isolate the fire protection system into training materials. However, review of the training records on June 12, 1997, by personnel from the E0 group resulted in additional questions regarding the licensee s corrective actions. The records reviewed by the E0 personnel indicated that during
'
simulator training, approximately 10 to 20 percent of the operators were failing to enter AOP-05,0, Radioactive Spills. High
. Radiation, and Airborne Activity, or were entering the AOP late
- (after 15 minutes). The inspectors made an indepen6nt review of
, the training records reviewed by the E0 personnel. This review disclosed that the records the E0 personnel reviewed on June 12, 1997 were for the six month 02015 (January - June 1997) The .
period prior to reviewed inspectors initiation of CR 97-training records for July - September, 1997 and noted significant improvement in this area, although the HELB scenario was not included as part of the simulator training exercises in this time period. The training scenario did include a torus leak which required entry into A0P-05.0.
I The inspectors noted that the concern regarding flooding of
_
instruments could also be caused by other accidents such as pipe L breaks in the service water or Reactor Building Closed Cooling l Water (RBCCW). Operator actions in these cases would be directed e by E0P-03 SCCP Secondary Containment Control Proccdure (SCCP),
based on high water leve'is in the HPCI and north and south RHR and core spray rooms. An uttry into E0P-03-SCCP would also result from flooding in these same rooms caused by activation of the fire protection system. As aaditional followup on this issue, the inspectors observed simulator training scenarios performed on December 3 and 17, 1997. Included in the scenario was a RCIC steam line break (HELB) and activitation of the fire protection system. Both crews participating in the training scenario isolated the fire protection system within the 15 minute time period. The inspectors also questioned some randomly selected reactor operators regarding the need for entry into A0P-0 following a HELB. The operators were cognizant of the basis of the actions in A0P-05.0 (need and reason for isolating the ' ire protection s CR 97-02015.ystem) and were familiar with the problem addrc ses by The inspectors verified the action items associated with the CR were complete CR 97-02015 was closed on December 11. 199 CR 97-01841. 97 02025. & 97-02408 These CRs documented various issues regarding possible effects of moisture on E0 equipment.

The problem documented in CR 97-02025 concerned an issue which had been the subject of IE Circular 79-05. Moisture Leakage in Stranded Wire Conductors, which was issued by NRC on March 2 . This affects Patel seals which were used to seal some stranded wire conductors in instrument circuits. CR 97-0?408 documents several other moisture intrusion issues. The immediate corrective action taken to resolve these issues, as documented in CR 97-02408 was to hire an outside consultant to address the issues. The consultant has reviewed many of the issues documented in CR numbers 97-01841, 97-02025. and 97-02408 and made recommendations, some of which have been implemen.ed. The consultant also addressed another issue in the CRs involving current leakage in control circuit and the possible impact on ODPs and E0 of equipment. This concern was the effect of moisture intrusion through stranded wire conductors, sealed with Patel seals, which could result in leakage currents in instrument circuits. ESR 97 00440 was issued for the 120 volt AC circuits and ESR 97-00441 for DC circuits. These ESRs are currently being reviewed by licensee engineers. The current leakage issue was also applicable to questions raised regarding the NAMCO limit switches. The inspectors will review the licensee's evaluation of current leakage and its ap311 cation to evaluation of E0 equipment in a future inspection.

This evaluation was i documented in ESR 97-00423. 03erability Evaluation - Wickin Review of the ESR disclosed t.at the licensee performed a detailed evaluation of the Patel seals by comparison of the installations at Brunswick with the configurations tested by NRC at Sandia Laboratorics (NUREG/CR 0699. Jublished March.1979). The licensee's conclusions were t1at the design function of the instellea equipment will not be effected by moisture intrusion through the stranded wire. The ESR was based on a review of the duration of the design accidents and the resulting leakage currents caused by moisture intrusion into limit switche Further review of this ESR will be performed as part of IFI 50-325 (324)/97-13-07, discussed abov CR 97-02016 & 97-02074 CR numbers 97 02016 & 97-02074 were initiated to document issues involving NAMCO limit switches. The following issues were identified in the CRs:

- Chemical reaction between paint and internal switch components would cause corrosion of switches, leading to failure of the switche * Use of incorrect qualification test reports (0TRs) in the qualification test reports which qualified the switche * Effect of current leakage on switch operabilit A total of 14 NAMCO limit switches were covered under the E0 program. These switches were installed during modifications completed in 1983 and 1984 The licensee has determined that none of the switches were purchased or manufactured prior to 198 Therefore, the concern raised by IE Bulletin 79-28. Possible Malfunction of NAMC0 Model EA 180 Limit Switches at Elevated Temperatures, would not apply to the switches installed at Brunswick, Review of the licensee's response to IEB 79-28 disclosed that none of the potentially defective switches had been purchased by the Brunswick sit Review of the i1censee's corrective actions completed to date disclosed that the following actions have been completed:
The licensee has identified the date of manufacture for most of the NAMCO limit switche Additional manufacture dates may be identified when the Unit 1 walkdowns are completed during the Spring 1998 refueling outage. However, the licensee has conclusively determined that none of the switches would be affected by the defects identified in IEB 79-2 .

[R 97 02367 This CR was initiated on July 3, 1997 to document the failure to initiate CRs for nonconforming items, specifically, MCC door gaskets and non standard Raychem splices identified as a violation by NRC during an inspection documented in NRC 1R 50-325 (324)/97 08.- The licensee's corrective actions included completion of a review of all the E0 walkdown data sheets to identify any nonconforming equipment. Additional corrective actions included training of personnel in the E0 group regarding the corrective action program and assessment of the effectiveness of the corrective actions. These correcthe actions were also associated with other similar corrective action CRs. such as CR 97 01972 and CR 97-02465. The inspectors reviewed the completed corrective actions and concurred with closure of CR 97 02367. The CR was closed on December 14. 199 CR 97-02465 and 97-02672 This CR wac initiated on July 15, 1997, to document concerns on EQ operability determination This CR referenced CR numbers 97-01841, 97 02025. and 97 02408. discussed above, which involve moisture intrusion issues. As a result of the concerns raised in CR 97 02465, the E0 group presented an action plan to resolve the moisture intrusion issues (CR 97 02465) to the plant nuclear safety committee. Although, further review showed the operability determinations for the three CRs were correct, the root cause analysis concluded that there were other problems which resulted in CR 97-0246 The root cause of CR 97-02465 was attributed-to weak E0 project management. The root cause/ event review for the CR listed the causal-factors indicative of weak E0 3roject management to be poor communications within the E0 group, tie site position that E0 problems were primarily docunitation problems, and a poor corrective action culture within the E0 group. The poor corrective action culture was evidenced by corrective action items which were routinely extended, overdue, or completed late: failure to prepare JCOs: numerous CRs written against the E0 grou) for improper corrective actions: and closing CR action items )y other action items without completing the corrective actions. A violation of NRC requirements was identified in IR 50 325, 324/97-12 for failure of the licensee to implement their corrective action progra The licensee's corrective actions to address the issues raised in CR 97-02465 included increased management oversight aerforming a review of the E0 project schedule to complete the higlest priority work activities first, conducting more frequent E0 group meetings to improve communications within the E0 group, transferring some E0 group functions from the Design Control l%1t to a site organization. and performance of an effer' ve. dss review of the

completed corrective actions. The CR was closed on December 17, 1997. The inspectors reviewed the completed corrective actions
.and concurred with closure of the CR. The ins)ectors concurred with the licensee's conclusions that the opera]ility determinations for the three referenced CRs were appropriate. NRC will perform review of the liccasee's actions to correct the l violation in future inspections, CR 97-02672, which was inniated on August 5. 1997, indicated that the Supervisor comments listed in CR 97 02465 were a misstatement of the consensus of opinion of individuals which met to discuss CR 97-02465. Review of CR 97-02672 disclosed that the CR did not raise any new issues or conceriis which had not been addressed by CR 97 02465. CR 97-02672 was closed on December 17, 199 NRC concurs with the licensee's conclusions and closure of the C CR 97 4059 This CR was initiated on December 2, 1997, to document concerns and questions on ESR 97-00426. The questions involved appropriateness of E0P actions, the need to include evaluation of drywell instrumentation in tic ESR, and various questions on instrument setpoints. The 1 Lensee completed a review of the questions raised in the CR and concluded that the ESR had addressed these issues, or the issues were beyond the scope of the ESR, For exam)le, appropriateness of E0P actions were approved by NRC for all BW1s and do not involve instrument setpoints. There are no instruments in the drywell which provide signals for automatic actuation. The inspectors reviewed the licensee's responses to the questions in the CR and concurred with the licensee's conclusions that no new corrective actions were required to resolve the concerns / questions raised in CR 97-04059-which had not been previously resolve ) Review of Environmental Qualification Requirements in Procurement Practices Th'e inspectors reviewed CP&L procedure MCP-NGGC-0401, Material Acquisition (Procurement.

Observations and Findinos The requirements for performance of E0 equipment walkdowns are specified in CP&L Special Procedure OSP-96-014. E0 Equipment Field Verification. The prerequisite in procedure OSP 96-014 for individuals performing the walkdowns was to read the procedur The licensee qualified a number of individuals to perform the field walkdowns through a training program conducted in accordance with CP&L procedure TI-100. Conduct of Training. These individuals included Instrumentation and Control technician contract engineers, and personnel assigned to the E0 group who were qualified E0 engineers. The training for the qualified E0 engineers consisted of reading the procedure. orientation and on-the-job training to become familiar with the walkdown and data s gathering process. For other personnel, the training included reading of the procedures, formal classroom lecture demonstrations, performance of practical exercises, and on-the-job training. The walkdown group supervisor performed a detailed review of the result < of practical exercises and data gathered <
during initial walke is prior to signifying the individuals were s. _ __
qualified to perform walkdowns. The training provided for the walkdcwn personnel exceeded the procedural requirements. The E0 walkdown grou) supervisor stated that the level of training provided to t1e walkdown personnel war to assure that the walkdown results were very accurate and to preclude the need for repeat work. The inspectors revieweJ the training records for the walkdown personnel and verified that they had been trained in accordance with the licensee's program. The inspectors noted that the experience level for the walkdown personnel varied from a recent graduate engineer to individuals with more than 20 years of experience. The inspectors reviewed the walkdown inspection records prepared by various individuals in the walkdown group and noted that the original walkdown records were complete and accurate, with some exceptions. Discussions with the walkdown group supervisor disclosed that corrections noted on the records were the result of reviews perfnrmed to resolve discrepancies in the records. The changes were made as a result of additional walkdown inspections which were doc'mented in the records. In one case, an individual was terminated for failure to perform the walkdowns and complete the walkdown records properl This individual's work was reviewed by the licensee and corrected where necessar The inspectors also reviewed the training and qualification records for E0 technical personnel. These records included previous work experience, education and training, and CP&L specific training applicable to the E0 project. This training included E0 technical reviewer, E0 design verifier E0 calculations, and E0 ESR originato The inspectors also questioned the manager of the E0 group concerning work assignments within the E0 grou). That is, assignment of specific activities to individuals wit 1 previous experience in a particular area of specialization, such as review of requirements for qualification of motors or specific types of instrumentation. The E0 group manager has recently are)ared a directory of all engineers working within the E0 group w11c1 lists each engineer's experience and what work activities they have completed for the E0 project at Brunswick. The purpose of this directory was for the engineers within the group to know who has worked on various problems and issues so they could obtain assistance from these individuals when they become involved with similar technical issues. The directory was distributed'to personnel in the E0 group. The E0 group manager provided a copy of the directory to the inspectors and discussed the basis for the various work assignments within the group.which were based on the past work experience of the E0 technical personnel, c. Conclusions The inspector concluded that the licensee's program for training and qualification of E0 engineers meets NRC requirement ,

In a letter to the NRC dated August 6. 1997, the licensee requested a license amendment for review of the US" The licensee re evaluated findings relative to the 30 foot dro: ~cident and qualified the transfer yoke using guidance provided in NUR b 0612. Control of Heavy Loads at Nuclear Power Plants. This evaluation contended that a fuel shipping cask drop event was not credible. therefore operation with less than full cask integrity was no longer a problem due to acceptable redundancy in the lifting yoke. In a letter to the licensee dated December 2. 1997, the NRC accepted the licensee determination that operation with the valve covers removed would not compromise the health and safety of the public due to acceotable redundancy of the lift devices. Based on the acceptance by the NRC of the licensee's evaluation and issuance of the enforcement action as described in IR 50-325(324)/97-12 this item is close .- . ._

40 Silicone foam Penetration Seals a. Inspection Stone (64704)
The inspector reviewed the fire barrier ,,ilicone foam penetration seal design end testing. The inspector compared as-built fire barrier silicone foam penetratioh seals to fire endurance test configurations to verify that the as-built penetration seals reviewed were qualified by appropriate fire endurance tests, representative of, and bounded by, the design and construction of the fire endurance test specimens. During plant walkdowns the inspector observed the installation configurations of selected fire barrier silicone foam 3enetration seals to unfirm that the licensee had established an accepta)le design basis for those fire barriers used to separate safe shutdown function b. Observations and Findinas The inspector reviewed the fire barrier seal design and testing for six
- of ten fire barrier silicone foam seal penetrations, Additional reviews I are documented in NRC 1Rs 50-325(324)/92-31, 93 08. and 93-3 The inspector reviewed Brunswick Specification No. 118 003, Revision Selection and Installation of Fire Barrier Penetration Seals

The licensee was unable to locate the penetration seal testing documentation and the vtador data for the tested prototype configurations or GL 8610 engineering evaluation documentation that evahated the adequacy of the deviations from a tested fire barrier contiguration. This does not satisfy the guidar.ce of GL 8610. The i
licensee stated that industry documentation is available to support silicone foam penetration seal installations at Brunswick but the
.tiformation was maintained at other Carolina Power and Light (CP&L)
site The penetration seal testing documentation, vendor data and inspection criteria, installer qualification and training records, and evaluations of deviations from tested fire barrier configurations will be reviewed during a subsequent NRC inspection. This is identified as IFl 50 325 (324)/97-13 04. Review of Licensee Records and Engineering Evaluations to Establish the Fire Resistant Capabilities of Fire Rated Silicone foam Penetration Seals, Conclusions The inspector concluded that silicone foam penetration seal field verification documentation was maintained by the licensee. The installation and repair procedures for penetration seals provided adequate guidance to ensure that materials were installed per design requirements. However, the designs were not supported by seal testing documentation, vendor data and inspection criteria, installer qualification and training records, and engineering evaluations that satisfy the guidance of GL 8610 for deviations from the fire barrier configuration qualified by test F2.3 Fire Doors Insnection Scone (64704)
The inspector reviewed UFSAR Section 9.5.1.4.3.4.b. Fire Doors, and performed plant walkdowns to verify that the UFSAR wording was consistent with the observed plant installation configurations for selected fire doors installed in fire barriers used to separate safe shutdown function Observations and Findinas The UFSAR St.ction 9.5.1.4.3.4.b. Fire Doors, states that doors and frames are either listed by a national testing laboratory or are constructed similar to listed doors and frames. All doors and frames have been evaluated to assure satisfactory ratings. Results are documented in the FHA. During the review of the FHA the inspector identified that, while evaluations of fire doors and frames existed. the-licensee failed to document their results in the FHA. which is section 9.5.1.5 of the UFSA , r ,,- ~ , - , , - , , - , - - - - - - - , -v ,
