Subject:
Ginna Station Inservice Testing Program Cold Shutdown Justification CS-37 R.E. Ginna Nuclear Power Plant Docket No. 50-244
Dear Mr. Johnson:
The purpose of this letter is to request NRC approval of the subject Cold Shutdown Justification, as attached.
This replaces quarterly testing requirements for valves MOV 897 and MOV 898 with testing to be performed during cold shutdown conditions as provided for in ASME OM Part 10 Section 4.2.
This request is made in accordance with the provisions of 10 CFR 50.55a(a)(3)(ii) in that testing of these valves during normal plant operations renders all three pumps in the high head safety injection system inoperable due to the series arrangement of the valves in the common recirculation line.
This condition requires entry into Technical Specification 3.0.3 which, in turn, requires that provisions be implemented to put the plant in Mode 3 status within six hours.
Since the normal and accident position of these valves is open, and the quarterly testing moves these valves from their accident
- position, performance of these testing requirements results in hardship and unusual plant conditions with no compensating increase in safety.
~ In fact, this testing results in the removal of an entire accident mitigation function due to closure of the common recirculation path.
Your action on this item by 10/31/96 would be greatly appreciated and would eliminate the necessity of performing the next quarterly test and having to enter LCO 3.0.3.
Very truly yours, Robert C. Mecredy REJ5437 y~oog9

Cold Shutdown Justification CS-37 (Proposed)
Valves:
~Sstem:
Cat ecaCor Function:
- 897, 898 Safety Injection B, Active P&ID:
33013-1261 Class:
2 These valves are in a series arrangement and serve as return isolation valves to the Refueling Water Storage tank (RWST) from the recirculation piping for the Safety Injection (SI) pumps.
These normally-open valves must remain open to provide low flow recirculation for the SI pumps during accident mitigation.
The close function is used during post-accident recirculation to isolate the recirculation path from the RWST.
Justification:
During power operation, these valves are maintained open to provide minimum flow protection for the high head safety injection pumps.
Closing either of the subject valves renders the high head safety injection system inoperable.
This condition requires entry into Technical Specification Section 3.0.3 which requires actions to be taken to place the plant in Mode 3 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />.
In addition, each entry to this section requires generation of an LER.
