Page 4 of-8 JUSTIFICATION NOTES Note 1 This is a vertical deep well type pump with the pump submerged under water at all times.
It is not practical to measure pump vibration in this type of installation. Past operating experience has shown that motor vibration is indicative of pump mechanical problems in this type of installation. Therefore, motor vibration will be measured in lieu of pump vibration.
Note 2 This is a vertical deep well type pump with the pump submerged under water at all times.
Pump bearings are lubricated by the fluid being pumped. There are no installed means of measuring bearing temperature and the pump design and installation makes it impractical to measure in any other manner.
Note 3 There are no flow meters installed in the flow path of this pump. Therefore test quantity "Q" cannot be measured. Prior to start-up for Cycle 7, GPUN will install flow metering for these pumps.
Note 4 Since there is no pump inlet pressure gauge installed, test quantities Pj and AP cannot be measured.
I Pumps SF-PIA /8 take suction on the Spent Fuel Pools. The pool water level is alarmed at 40 feet (high) and 38-1/2 feet (low).
This is a 1-1/2 foot (0.65 psi) difference. Therefore, SF-PIA /B suction pressure is nearly constant (can vary only by a maximum of 0.65 psig and this maximum difference in level is less than a 1 psig typical minor scale division).
ASME Section XI, IWP-3100 states that the testing method for IST shall be that either AP, or flow rate shall be throttled to a reference value. Since suction pressure gage taps are not available for SF-PIA /B, discharge pressure instead of AP is the throttled reference condition.
Flow rate is then measured as the i
dependent variable.
e
TABLE A THREE MILE ISLAND - UNIT NO. 1 PERIODIC. INSERVICE INSPECTION PROGRAM - (PUMPS)
EXCEPTIONS TO ASE XI REQUIREMENTS Page 5 of 8-JUSTIFICATION NOTES (Cont.)
Current reference values are:
Discharge Pressure (psig)
Flow Rate (gpm)
SF-PIA 59 818 SF-PIB 62 7 58 Discisarge pressure is considered the independent variable. Since suction pressure is relatively constant, a suction pressure gage is not needed to determine the operational readiness of SF-PIA /B.
This method of testing meets the intent of the ASME Code Section XI test requirements and ensures the operational readiness of these components without measuring AP or Pj.
Note 5 Pump bearing temperature cannot be measured on this pump since the bearings are located deep inside the pump casing and are surrounded by an oil reservoir. An exception is requested per 10 CFR 50.55a(g)(5)(iii) in that measurement of parameter Tb is not practical within the limits of the design of this pump.
Note 6 Flow metering for this system is located in the common discharge lines from all three pumps. Plant operating heat loads require the operation of at least two Nuclear Service River Water pumps during normal plant operation, thereby making it impossible to measure flow for a single pump. Pump flow will be measured for each pump during plant refueling outages when operation of only one pump is required.
Note 7 There are no flow instruments in the flow path of these pumps.
Therefore, test quantity "Q" cannot be measured. As an alternative, the discharge at the spray nozzles will be observed during each test to determine if sufficient flow is available to wash the screens.

l The Emergency Feedwater Pumps (EF-P1 and EF-P2A/B) are tested on recirculation to the Condensate Storage j
Tanks.
Installed orifices limit flow rate to a fixed value. Therefore, testing is conducted with Q as the j

Flow metering for this system is located in the common discharge lines from all three pumps. Plant operating 6
i heat loads require the operation of at least two Nuclear Service Closed Cooling Water pumps during plant-j operation thereby making it impossible to measure flow for a single pump. Therefore, two-pump testing will 1
be conducted on a quarterly frequency. Three two-pump tests will be performed as follows:
(1) pumps A and B (2) pumps B and C, and (3) pumps A and C.
Two-pump testing will be conducted in accordance with the requirements of ASME Section XI, Subsection IWP. Single pump testing will be performed during each refueling outage.

Note 11
{
The Reactor Building Cooling Water Pumps (RR-PIA /B) supply river water to the Reactor Building Emergency j
Cooling coils. These pumps will be tested during normal plant operation using a fixed resistance flow path that bypasses the cooling coils. This test will not measure flow rate. The testing during normal plant
.i l
operation will not pump river water through the cooling coils because after the test, the cooling coils must I

be drained and then flushed with Nuclear Service Closed Cooling Water. The drain and flush water is drained
[
t to the Reactor Building Sump and this produces large quantities of water that must be processed through the Liquid Waste Disposal System. However, flow rate will be measured during refueling outages, when river water is pumped through the cooling coils in accordance with Technical Specification requirements.
Note 12 For CA-PIA /B and WDL-P13A/B, GPUN requests relief from the measurement of Q, A P, Pj, and the 5 minute run time.
In addition, relief is requested to perfonn testing only during refueling outages.
i j
Without recirculation capability, the only method of testing these pumps is to inject into the Reactor Coolant Makeup System. The resulting reactivity changes would affect plant operations adversely and would i
result in significant volumes of radioactive waste. For these reasons it is impractical to test the subject r
)
pumps during operation or during cold shutdown.
The appropriate test interval is each refueling.
i In a conference call with NRC on May 21, 1984, the following test program was agreed upon in order to meet j
the intent of the ASE Code Section XI test requirements-l 1
(
t 1.
Tests of the subject pumps will be conducted each refueling interval.
2.
Pump differential pressure ( AP) will be calculated, not measured, since pump inlet pressure (Pj) is not available (there are no existing pressure gauge taps).
(
l 3.
Flow rate (Q) will be calculated using tank level change over time, since installed flow measuring instuments do not exist.
i ASME Section XI IWP-3500 states that pumps under test should be run for at least 5 minutes under conditions l
l as stable as the system permits prior to taking data. To minimize radioactive waste, the subject pumps will i
be run until the system is stablized and then data will be recorded. GPUN believes this meets the intent of 1
IWP-3500.

ASME Section XI, IWP-1100 states that emergency powered pumps should be included in the IST Program.
WDL-P13A/B are not emergency powered, but are included in the IST Program as requested by NRC. The addition of WDL-P13A/B in the program provides further assurance of the capability to supply concentrated boric acid to the Reactor Coolant Makeup System.
Note 13 The pump and motor form an integral unit. The pump bearings are located in the motor. There is no lubrication level on the pump that can be checked. Also yearly bearing temperatures will not be measured since the bearings are deep inside the motor end caps.

DH-Y128 is in the supply line from the Reactor Vessel to the "B",. Decay' Heat Pump.
For post-accident boron precipitation concerns, DH-V128 may be locked open during nomal plant operation.
If DH-V12B is locked open, it will become passive and therefore, functional stroke testing of this manual. valve will be discontinued.
(2)
This CIV is passive (a closed valve whose function is to remain closed). Therefore, this valve is exempted from the quarterly functional stroke requirement of IWV-3412 per NRC' staff guidelines since no meaningful information would be gained.
(3)
DH-V1 and DH-V2 are the two high pressure valves in the decay heat drop line (suction line to LPI pumps).
During normal plant operation, these valves cannot be cycled because the margin of safety would be reduced by opening either of these two pressure. barrier valves. Therefore, per ASME Section XI IWV 3412, these valves will be tested on a cold shutdown frequency.

Therefore, these Fluid Block Check Valves are passive and are exempted from the quarterly functional stroke requirement of IWV-3522. The closed function of these valves will be verified in that any leakage will be measured in conjunction with refueling interval Appendix J testing of the associated CIVs.
Amendment 93 to TMI-l's Technical Specifications, issued May 18, 1984, deletes the above valves from Appendix J 1eak rate testing requirements. Therefore, it is our intention to disable the Fluid Block System to the gate type CIVs by positive methods. When this is done, the above valves will be deleted from the IST Valve Program.

IC-VIA/B supplies cooling water to the Primary System Letdown Coolers.
In accordance with B&W guidance and the failure history of the Letdown Coolers it is not advisable to thermal cycle the Letdown Coolers by isolating cooling water to an operating Letdown Cooler. Thermal cycles increase thermal stress which increases the potential for tube leakage. Therefore, per ASME Section IWV-3412, IC-VIA/B will be tested at cold shutdown frequency.
(2)
These valves are in the supply or return lines to the Primary Letdown Coolers, Control Rod Drive Cooling Coils, Reactor Coolant Pump Heat Exchangers and/or R.C. Drain Tank Heat E:: changer.
It is not possible to stop flow in these lines to test these valves without upsetting the reactor plant. Therefore, in accordance with ASME Section XI, IWV-3412, these valves will be tested at cold shutdown frequency.

MS-V2A/B isolate the six turbine bypass valves. MS-V2A isolates three turbine bypass valves and likewise MS-V2B isolates the remaining three turbine bypass valves. Technical Specification 3.4.1 requires four of the six turbine bypass valves to be operable.
If MS-V2A/B stuck closed during a quarterly test this would limit the ability of the plant to cooldown. Normal cooldown decay heat removal is by the steam generator through MS-V2A/B to the turbine bypass valves ana then to the condenser. Therefore, per ASME SEction XI IWV-3412, these valves will be tested on a cold shutdown frequency.

MS-V13A/B is a 2" valve in parallel with MS-V10A/B, which is a 6" valve. Upon loss of both Main Feedwater Pumps or upon loss of all four RC pumps, MS-V13A/B opens to supply steam from the OTSG's to the Turbine Driven Emergency Feedwater Pump (EF-P1).
Then at approximately 300 psig steam pressure, MS-V10A/B is jogged open to maintain steam pressure to EF-Pl. To preclude the possibility of challenging the safety relief valves for EF-P1's turbine (MS-V22A/B), MS-V10A/B will only be tested at cold shutdowns, in accordance with ASME Section XI IWV-3412.

MU-VIA/B is the upstream valve at the Primary Letdown Cooler.
In accordance with B&W guidance and the failure history of the Letdown Coolers it is not advisable to thermal cycle the Letdown Coolers by closing MU-VIA/B.
Thermal cycles increase thermal stress which increase the potential for tube leakage. Therefore, in accordance with ASME Section XI IWV-3412, these valves will be tested on a cold shutdown frequency.
(2)
MU-V12 isolates the Makeup Tank from the suction of the Makeup Pumps. Part-stroking this valve during normal plant oneration would jeopardize the continued operation of the running Makeup Pump if this valve completely closed oue to valve operator malfunction.
Likewise, part-stroking MU-V20 would jeopardize the continued operation of the Reactor Coolant Pumps, since this valve supplies seal injection water to the Reactor Coolant Pumps. Therefore, in accordance with ASME Section XI IWV-3412, these valves will be tested on a cold shutdown frequency.
(3)
MU-V18 is in the normal make up supply leg to the Reactor Coolant System. During normal plant operation, MU-V18 cannot be closed due to limited number of allowable thermal cycles (40) on the high pressure injection nozzles. Therefore, in accordance with ASME Section XI, IWV-3412, MU-V18 will be tested on a cold shutdown frequency.

RC-V3 is the block talve for the pressurizer spray line. Part-stroking RC-V3 during nonnal operation would jeopardize the ability to spray the pressurizer and reduce pressure if RC-V3 stuck closed. Therefore, in accordance with ASPE Section XI IWY-3412, RC-V3 will be tested on a cold shutdown frequency.

EC-V4 and RC-V23 are the two high pressure valves in series that supply Auxiliary Spray to the Pressurizer.
These valves are used only during cooldown of the pressurizer. RC-V4 and RC-V23 will not be part-stroked during normal plant operaticn because the margin of safety would be reduced by opening either of these two pressure barrier valves. See NRC letter to Med-Ed dated November 17, 1976 Enclosure 2, paragraph 3.
Therefore, per ASE Section II IW-34I2 and IW-3522, these valves will be tested on a cold shutdown fre<;tency.

RC-V28 and RC-V44 are the two in series Pressurizer Vent Yalves. RC-Y40A/B and RC-V41A/B are the two High Point Vent valves in series.
RC-Y42 and RC-Y43 are the two Reactor Vessel Head Vent valves in series. All of the valves are closed during normal plant operation. These valycs will not be part-stroked during normal plant operatien because failure of one of the valves in a non-conservative position (open) during the cycling test wculd cause a loss of double barrier isolation for the RC System. Therefore, per ASME Section II IW-3412, all of these valves will be tested on a cold shutdown frequency.

In order.to. flush the river water the suction-valves of the Emergency Feedwater Pumps must be closed while performing the flushing operation. This would render the Emergency Feedwater Pumps inoperable during the flushing operaticn. Also, these valves are chained and locked shut and the breakers for these valves are open at the 480 volt power supply.

C.
Basis for Requesting Relief The only method of functionally testing check valves CA-V177, WDL-V353, V354, V361, and V362 during normal operation is to inject concentrated boric acid into the Reactor Coolant Makeup System producing reactivity changes.

Testing these' valves during each cold shutdown is not warranted because of the radioactive waste generated._ In a conference call with the NRC on May 21, 1984, it was agreed that the concentrated boric. acid. pumps (CA-PIA /B and WDL-P13A/B) and valves associated with these pumps be tested on a refueling interval frequency. All of the above valves are associated with the concentrated boric acid system.
Therefore, to ensure consistency, pump testing and valve testing will be conducted on a refueling interval frequency. Also the system for these valves is not relied upon for accident mitigation in chapter 14 of TMI-1 FSAR. The Borated Water Storage Tank is the accident source of Borated Water via LPI or HPI. However, general design criteria does require a concentrated boric acid injection system.
In conclusion, GPUN believes that refueling interval testing meets the intent of the code and will assure the operational readiness of the above valves.

Basis for Requesting Relief The Reactor Safety Study (RSS), WASH-1400, identified a PWR intersystem loss of coolant accident (LOCA) which is a significant contributor to risk or core melt accidents (Event V).
The design examined in the RSS contained in-series check valves isolating the high pressure Primary Coolant System (PCS) from the Low Pressure Injection System (LPIS) piping. The

scenario which. leads to the Event V accide'nt is initiated by the failure of these check valves to function:as a pressure isolation barrier. This causes an overpressurization and rupture of the LPIS low pressure piping which results in as LOCA that bypasses containment.
J; j
Valves CF-VSA/B and DH-V22A/B'are inside containment and are located in the supply line from 1
the LPI pumps to the Reactor Vessel. Therefore, these two valves are of the Event V configuration. Valves CF-VSA/B and CF-V4A/B are in the line from the Core Flood Tanks to the i
Reactor Vessel. A pressure isolation failure of CF-V4A/B does not lead to a LOCA outside i
containment. Therefore, CF-V4A/B is not included in Technical Specification 3.1.6.10.
However,.TMI-1 has elected to test these valves. for pressure isolation function on the same frequency as of CF-VSA/B and DH-V22A/B.
i The NRC's Technical Evaluation Report (prepared by Franklin Institute) states that the testing frequency of CF-VSA/B and DH-V22A/B shall be prior to achieving hot shutdown following a cold shutdown of greater than 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> duration unless testing has been performed within the previous 9 months, and prior to achieving hot shutdown after returning the valve to service following maintenance repair or replacement work.
The Technical Evaluation Report (TER) provides a comprehensive study and evaluation of the l
specific problem related to pressure isolation. Since the TER has specified and judged adequate the above testing frequency, there is reasonable assurance that these valves will perform their pressure barrier function.

TABLE B-2 THREE MILE ISLAND - UNIT NO. 1 PERIODIC INSERVICE INSPECTION PROGRAM - VALVES REQUEST FOR RELIEF FROM ASME CODE SECTION XI REQUIREMENTS PAGE 10 of 13 C.
Basis for Requesting Relief Valves CF-V4A/B are part stroke tested each cold shutdown per Surveillance Procedure 1303-11.21.
Both CF-V5A/B and CF-V4A/B are of the same design and manufacturer. CF-VSA/B are in operation whenever the plant is on Decay Heat Removal and are normally closed during plant power operations.
CF-V4A/B are in operation whenever Core Flood is required and are normally closed during plant power operations and during Decay Heat Removal System operation. CF-VSA/B are also in operation whenever Core Flood is required. Therefore, CF-V5A/B are in operation more than CF-V4A/B and have more possibility for degradation during operation. The refueling interval full flow Low Pressure Injection System testing of CF-VSA/B showing no degradation during service can be applied to CF-V4A/B because the service for CF-V4A/B is less severe than that of CF-V5A/B. CF-VSA/B are full stroke tested per the code and CF-V4A/B are the same valve catalog number as CF-V5A/B, therefore we feel confident that our proposal to only part stroke CF-V4A/B should be adequate. Additionally, one of these valves (CF-V4A/B or CF-VSA/B) will be disassembled for visual examination at or near the end of the 10 year ISI interval per Table IWB-2500.
MS-V9A/B supplies steam from the OTSGs to EF-U1. EF-U1 is the turbine driver for EF-Pl. The quarterly test of MS-V9A/B provides 48% flow through these valves which equates to approximately 36% open. This test is accomplished with EF-P1 on recirculation to the Condensate Storage Tanks. A cold shutdown full stroke test of this valve is not possible since steam is not available from the OTSGs when the plant is cold. Also, when the plant is hot it is not possible to full stroke MS-V9A/B since this would require pumping cold water to the OTSGs. This would reduce the margin of safety by challenging the OTSG tubes and reduce the number of allowable thermal cycles for the emergency feedwater nozzles.
In conclusion, GPUN believes that the quarterly test of 48% flow provides reasonable assurance that these valves will function fully open when needed.

Basis for Requesting Relief Given the pipe geometry there is no method of part-stroking or full-stroking these check valves without contaminating the RCS with Sodium Hydroxide and other chemical contaminants in the dead leg of piping from these valves to the Sodium Hydroxide Tank. During January, 1984 (Surveillance Procedure No.1300-3P and Job Ticket No. CC818 and CC819) these valves were disssembled and satisfactorily visually examined. The valve internals were found to be in "like new" condition. Disassembling each of these valves at or near the end of the ten year ISI interval provides reasonable assurance of the operational readiness for BS-V52A/B.

On 6-20-84 (Job Ticket CE-154) BS-V30A was disassembled for visual examination purposes. The-examination was satisfactory (no unusual-degradation and valve disc was free to open).
BS-V30A has approximately 10 years of in-service time and this is the first time that the valve has been opened. GPUN will continue to disassemble either of these static valves (alternating between A and B) during each ten year inspection interval. BS-V30A/B are j
stainless steel and therefore, not subject to corrosive attack. GPUN is of the opinion that quarterly partial stroke testing and disassembly, as described, will provide reasonable assurance that BS-V30A/B would open if needed.

-C.
Basis for Requesting Relief The above valves have full stroke time of less than one second. Thus, the valve stroke time cannot effectively be measured using normal-test equipment such as a stopwatch. Also it is considered impractical to reliably measure. changes in valve stroke times for valves which j
stroke open or closed in less than one (1) second.
For very short stroke times, the variation in measured stroke times can be a large. fraction of the established stroke time limit. Thus j
it is not practical to meaningfully identify or evaluate the stroke time changes considering l
human reaction times and the normal timing equipment used.
In accordance with ASME Section XI IWV-3413, the maximum acceptable full-time stroke value for each of the above valves will be specified. This will ensure the operational readiness of these valves.
X.
FW-V12A/B During plant operation these valves are always open supplying feedwater to the OTSGs. Therefore it is not possible to part-stroke or full-stroke these valves closed during plant operation.
Both FW-V12A/B were disassembled in 1980 after approximately four years of service and were found to be j
in satisfactory and operable condition.
i As discussed with NRC in a conference call on May 21, 1984, GPUN will develop a test method (s) to i
verify the operability of FW-V12A/B.
If the. test method which was discussed at that time is not j
feasible, GPUN will pursue other alternatives.
In the interim, results of the 1980 disassembly of both FW-V12A/B provide a reasonable basis for assurance that FW-V12A/B will remain operable.
