Docket Nos. 50-272 and 50-311 Mr. C. A. McNeill, llr.

Vice President - Nuclear May 27, Public Service Electric and Gas Company Post Office Box 236 Hancocks Bridge, New Jersey 08038

Dear Mr. McNeill:

1986

. DI;STRIBUTION UPocket Fi1 e L PDR PAD#3Rdg OELD B. Grimes D. Fischer ACRS 10 NRC PDR Gray File H. Thompson E. Jordan J. Partlow C. Vogan N. Thompson As a result of the staff 1s reviews of the latest rev1s1ons of the heatup and cooldown curves for the Salem Unit 1 and Unit 2 facilities, the following request for additional information should be included in PSE&G 1s evaluation of future Unit 1 and Unit 2 surveillance capsules.

For Unit No. 1, according to the surveillance capsule withdrawal schedule in Section 7 of WCAP 10694, the next capsule will be removed when the reactor vessel has been in operation for 6 EFPY.

The information to be included in the evaluation of this capsule is documented in Attachment 1. Since the withdrawal of this capsule is 4 EFPY earlier than the effective perio9 for the Salem-1 pressure-temperature limits, the information requested in Attachment 1 will be available early enough for the licensee and the staff to determine whether the pressure-temperature limits curves require adjustment to meet the safety margins of Appendix G, 10 CFR 50.

For Unit No. 2, according to the surveillance capsule withdrawal schedule in Table 7-1 of WCAP 10492, the next capsule will be removed when the reactor vessel has been in operation for 3 EFPY.

The information to be included in the evaluation of this capsule is documented in Attachment 2.

Since the withdrawal of this capsule is 4 EFPY earlier than the effective period for the Salem-2 pressure-temperature limits, the information requested in Attachment 2 will be available early enough for the licensee and the staff to determine whether the pressure-temperature limits curves require adjustment to meet the safety margins of Appendix G, 10 CFR 50.

The reporting and/or recordkeeping requirements of this letter affect fewer than ten respondents; therefore, OMB clearance is not required under P.L.96-511.

ATIACHMENT 2

  • ADDITIONAL INFORMATION TO BE INCLUDED IN EVALUATION OF FUTURE SALEM-2 SURVEILLANCE CAPSULES
1)

The discrete ordinate code i~put used to calculate the capsule neutron flux should include a pin-by-pin (outer row) power distribution or a justification for not using pinwise power distribution.

2)

For each* fuel assembly use plant specific power distribution in lieu of time-averaged conditions derived from statistical studi~s of long-term operation of Westinghouse 4 loop plants.

3)

If the licensee us~s low leakage cores (twice or thrice burned assemblies in outer row of core) neutron analysis should account for the presence of the Pu239. and P-u241 isotopes.

4)

Which foil reactions are considered to produce the best estimated capsule neutron exposure? Provide the justification for your choice.
