Approval Request - .

Reactor Vessel Haterial Surveillance Program - Withdrawal Schedule Centlement By letter PY-CEI/NRR-1313Ls dated 3/15/91, a supplement to a Technical Specification change request was filed in order to relocate the Reactor Vest,el Material Surveillance Program - Withdrawai Schedule to the Updated Safety Analysis Report (USAR) in accordance with Generic Letter 91-01. This relocation is justified since the withdrawal schedule is controlled in accordance'with Federal Regulations in 10CFR50 Appendix H (Paragraph 11.B.3),

which requires NRC_ approval prior to implementing a revised schedule. A new j proposed schedule is attached, in the USAR Section 5.3.1.6.1 format which we propose to retals it.. Where. Effective Full Power Years (EFPY) d it coincide with refuel _ outages, withdrawal will be at the preceding o ..ge.

.The technical justification for this proposed withdrawal schedule is Table 1

-of ASTM E185-82, as referenced _in 10CFR50 Appendix H. The original schedule L was based on ASTM E185-73 (veer 91 purchase order 3/23/73), which originally provided for two surveillaneg capsules and a standby. Case A of Table 1 was used because less than a 100 F transition temperature shift was predicted at

-that time.

H Using the most recent regulatory guidance (RC 1.99 Rev. 2, 5/88) to_ calculate transition temperature shift, a shift of 110 F at Gud o' life !.s now predicted. This analysis is reported in' letter PY-CEI/NRR-11d8L, dated 9/14/90. ASTM E185-82 would require 4 capsules removed at 3, 6, 15 and 32 ef fegtive full power years. The.3 year withdgawal is based on reaching SE22 n/cm neutron fluence at1 the capsule, or.a 50 F temperature shift. Since our j specimen will not experience that fluence or_ temperature shift that soon, we f

.have selected our 3 capsule schedule to coincide _with capsule withdrawals at l

'l 6, 15, and 32 EFPY. The Perry surveillance capsule fluence and temperature-shift at 6-and 15 EFPY are consistent with E185-82 limits on fluence and-

' temperature shift.

USNRC March 15, 1991 PY-CE1/NRR-1314 L We also request to design =co the 32 EFPY (end-of-life) capsule as a standby, for possible changes in extended life surveillance if we elect to apply for license ronewal.

This withdrawal schedule was originally included in a more extensive Technical Specification Change Request for Regulatory Guide 1.99 Rev. 2 implementation (PY-CEI/NRR-1188L, 9/14/90). At that time we concluded the change to this schedule did not involve s significant huJard, and that the proposed change met the criteria in 10CFR$1.22(c)(9) for a categorical exclusion from the requirement for an F,nvironmental lipact Statement.

To remain consistent vith the related Technical Specification Change Request in our letters PY-CCI/NRR-ll88L and 1313L, we are requesting your approval of the attached Schedule cha.tges when the referenced Amendment is issued. - The vithdrawal schedule contained in the USAR, .lection 5.3.1.6.1 will be revised at the next USAR update following NRC approval of this eithdrawal schedule.

If you have any questions, pleast feel free to call.
