Subject:
Beaver Valley Power Station, Unit No. 2 Docket No. 50-412, License No. NPF-73 Updated Inscrvice Testing Program, Issue 1, Revision 13
)
The purpose of this submittal is to provide the Nuclear Regulatory Commission (NRC) with an informational copy of revisions to the Beaver Valley Power Station Unit 2 (BVPS-2) Inservice Testing (IST) Program.
Enclosure 1
provides a summary of the IST program changes which have been incorporated into Revision 13.
Enclosure 2
is Issue 1,
Revision 13 of the BVPS-2 IST Program.
It has been determined that the IST program changes do not require NRC appreval prior to implementation.
This determination was made because all of the changes are either:
editorial in nature, or in compliance with the 1983 Edition through Summer 1983 Addenda of the ASME XI Code, or in compliance with the positions delineated in Attachment 1 of Generic Letter No.
89-04,
" Guidance on Developing Acceptable Inservice Testing Programs."
If you have any questions regarding this submittal, please contact Mr. Nelson R. Tonet at (412) 393-5210.

DiCLOSURE 1
SUMMARY
OF GANGES 'IO 'IHE UNIT 2 IST PROGPAM (REV.13)
- 1) Revised the shape of the Mininum Operating Point (IOP) Curve for the "C" Camponent Coolirg Water Pump [2CCP*P21C] (page 57), based on a recent pump curve charge. 'Ihe IOP was not changed.
Testiry of the Law Head Safety Injection Pumps ard Geck valves will be in 20ST-11.14A, and testing of the High Head Safety Injection Pumps and Geck Valves will be in 20ST-11.14B versus both being done in 20ST-11.14 (pages 7-9, 14, 15, 87,97-101, 195-199, 201-202). 'Ihis was done to make this i
rather large test more manageable.
3)
Deleted marging Pump Miniflow Discharge Header Isolation Valve
[2GS*MOV373)
(page 90) from the BVPS-2 IST PrWtmu. Since this valve is Category B/P (passive) and is now de-energized open to meet NRC Branch
'Ibchnical Position ICSB 18 (to prevent spirious closirq of safety related MOV's),
it no larger requires a remote position verification per the ASME XI Code.
Wwe there is no longer any testire requirements for this
- valve, it has been removed from the BVPS-2 IST Pr@tma as documented in the IST Program Basis Document. (ref: IER 2-94-002)
- 4) Revised the test referenced for remote position verification (RPV) of
[2 SIS *HCV868A ard B]
(page 102) from 2OST-11.14 to 20ST-1.10.
'Ihe test conditions needed to RPV these valves did not " fit" well in 20ST-11.14 (SI Full Flow Test).
5)
Deleted all references to 2BVT 1.21.1 (pages 124-126) since this test has l
been revoked.
'Ihe Trevitest Method for Main Steam Safety Valve Setpoint Geck (2BVT 1.21.2) will continue to be used to test all the Main Steam i
Safety Valves.
- 6) Added testiry of Radiation Monitor (2 MSS *RQIl01A,B,C) Discharge Isolation Valve [2 MSS *SOV120]
(page 126) to the BVPS-2 IST Program. 'Ihe valve was recently determined to have a containment isolation function to close and must also open on an SI signal.
It was not previously included in the l
BVPS-2 IST Program because its opening function was determined not needed I
to mitigate an accident since several other means are available for determining a faulted steam generator (as documented in the IST Prugtmu Basis Document).
It will be stroked and timed open and closed quarterly per 20ST-47. 3A(3B).
Radiation Monitor Discharge Isolation Valve
[2 MSS *SOV120] was also added to Relief Request No. 30 (page 223) as a Rapid Acting Valve in both the open and closed directions as permitted by Generic letter No. 89-04, Attachment 1, Item 6.
7)
Corrected the referenced 04 drawirq number for [2SVS*HCV104] (page 128) from 21-1 to 21-2.

SUMMARY
OF CHANGES 70 THE UNIT 2 IST PROGPN4 (REV.13) (continued)
- 8) Per the revised response to QA Audit BV-2-93-01 (Observation No. 5),
[2FKE*HCV100A thru F]
(page 131) will now be stroked and timed in 2OST-47.3A(3B) and deleted frm 20ST-24.1.
- 9) Added (2SWS*7CV101A, B)
Bypass Valves [2SWS*99 and 100] (page 135) and Control Roam A/C Cordenser (2SWS*7CV101A, B) Outlet Isolation Valves
[2SWS*152 and 153]
(page 138) to the BVPS-2 IST Pr@ rmu in response to SWOPI Team Audit Question PCS-6.
These valves are normally throttled or open to support normal Control Room air conditioning, and must be able to be closed duriry an accident to ensure that sufficient SWS flow is p mvided to the backup control Room cooling coils if normal Control Roam cooling is lost.
The valves will be stroked closed quarterly per 20ST-47. 3A(3B).
- 10) Revised the full stroke reverso direction test referenced for [2SWS*106 and 107]
(page 136 and 182) from 20ST-30.8 to 20ST-30.8A or 8B per new issue of the OST.
- 11) Added Strainer Backwash Throttle Valves [2SWS*115A and B] (page 137) to the BVPS-2 IST Pr@rmu as r m - a nled in NRC Information Notice 94-03 (Deficiencies Identified Durity Service Water System Operational Performance Inspections).
The valves were already being stroPad to the open throttled position quarterly per 20ST-30.17A and 20ST-30.17B.
- 12) Deleted Main Steam Valve Area Cooliry Coil FCV's [2SWS*FCV120A and B]
(page 137) from the BVPS-2 IST Fr@tmu. These valves are Category B/P (passive) and do not have any remote position indication; therefore since they no longer have any testing requirements, they have been removed fram the BVPS-2 IST Program as documented in the IST Pr@tmu Basis Document.
- 13) Revised the NSA position for Ctm Air Recirc Cooling Cbils Inside/Outside QM Service Water Inlet / Outlet Ie71ation Valves [2SWS*MOV153-1, 153-2, 154-1 and 154-2] (pages 138 and 139) from Shut (S) to Iccked Shut (IS).
- 14) Added Service Water Chemical Injection Subsystem Check Valves [2SWS*1166 and 1167]
(page 140) to the BVPS-2 IST Program following permanent installation.
These check valves have a function to close to prevent required Service Water flow from draining into the SWS valve pit should a pipe break of the 3"
NNS Chemical Injection piping occur during an accident.
A reverse direction test of the check valves will be performed quarterly per 20ST-47.3A(3B).

SUMMARY
OF CHANGES 70 THE UNIT 2 IST MOGRAM (REV.13) (continued)
- 15) Added Emergency Diesel Generator Starting Air Tank Excess Flow Check Valves [2EGA*118,
- 119, 155 and 156) (page 146) to the BVPS-2 IST FRepcua as r - nded by the NRC during Oleck Valve Audit Inspection 94-09.
These check valves were detennined to have a function to close during an accident to prevent the Starting Air Tanks fran blowing down and not being able to start and run the Emergency Diesel Generators. An excess flow closure test of the check valves will be perfonned gaarterly per 20ST-47.3A(3B).
1
- 16) Revised the test method and reference test for Emergency Diesel Generator Campressor Discharge Check Valves to the Starting Air Tanks [2EGA*100,
- 101, 130 and 131] (page 146) to closed only per 20ST-47.3A(3B). The past method of monitoring Starting Air Tunk pressure per shift logs to verify the check valves were opening and closing was changed to a leak test to ensure check valve closure. The opening function was determined to not be
{
required in an accident (as documented in the IST Program Basis Document) since the Air Campressors were Category II and the volume in the Starting Air Tanks alone was designed to start and run the Emergency Diesel Generators.
A reverse direction test of the check valves will be
~
performed quarterly per 20ST-47.3A(3B).
