Subject:
Nine Mile Point 2 Main Steam Isolation Valves In Supplement 5 to the Safety Evaluation Report (SSER-5) for Nine Mile Point 2
(NMP-2) the staff identified the prototype test program to be performed on the main steam isolation valves (MSIVs) as a confirmatory program.
This position was based on a belief and understanding that the root causes and corrections for valve problems had been identified and would be resolved for early opera-tion of the plant.
The NRC staff has had several recent conversations with your staff reaarding the progress of your prototype testing proaram for the MSIVs.
Based on the information provided during these discussions, we no longer consider the prototype test program to be confirmatory, but we consider acceptable results from the prototype test proaram to be required to justify operation of NMP-2 with the MSIV ball valves for the first fuel cycle.
Enclosure 1 identifies what we consider to be the minimum testing, elements of which are in addition to that required by the MSIV license condition, and additional information that will be required to demonstrate that the valves will operate as required.
We now consider your testing program to be a devel-opmental program to demonstrate the acceptability of these valves and their ability to meet regulations and Technical Specification requirements.
In addition, we note your license requires that the results of the prototype test program be submitted by May 15, 1987.
If, because of problems that have been or <vill be encountered in the testing program, you are not able to meet that date, then a request to amend the license should be submitted in a timely manner.
We are ready to provide any necessary clarification of our position. on MSIV testing as discussed above and in the enclosure.
Please advise the Project
- Manager, Ms. Mary Haughey on (301) 492-9422 should you wish to discuss this issue with the NRC staff.

NMP-2 MINIMUM TEST PROGRAM TO DEMONSTRATE ACCEPTABILITY OF HSIV BALL VALVES ENCLOSURE I PRIOR TO CRITICALITY 1.
PROTOTYPE TESTING a) complete testing on the valve assembly with the first ball to qualify the valve assembly for the number of actuations expected for the first fuel cycle; b}
complete testing on the val,ve assembly with the second ball to qualify the valve assembly for the number of actuations expected through the 100 hour0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br /> warranty run; c) verify that the prototype test program encompasses expected plant operation; and d)
. perform an additional Type "C" test during the prototype tests follow-ing the HSIV heat-up at a point which corresponds to the HSIV closure test following operation in test condition I (see item 2C); the accep-tance criteria for this test shall be 6 SCFH.
2.
PLANT VALVES a) replace packing in all eight NSIVs with packing demonstrated to be acceptable during prototype testing discussed above; perform preoper-ational closure time and Type "C" tests in accordance with the Technical Specifications and Appendix J; b) verify that the plant valve assemblies are replicates of the proto-type test valves; and c) commit to Type "C" test all of the plant HSIVs when the MSIV closure tests are performed following test condition 1 (this testing is in addition to, not in place of, other Type "C" tests required by the license and the regulations).
3.
Verify that the problems with the ball valves in Leibstadt, Switzerland, as documented in the October 1986 report from General Electric, have been resolved for the NHP-2 MSIVs.
4.
Submit for NRC review the results of items I, 2 and 3 above.
