SUBJECT:

CLOSEOUT FOR THE.CONSUMERS POWER COMPANY RESPONSE TO GENERIC LETTER 92-01, REVISION 1, SUPPLEMENT 1, FOR THE PALISADES PLANT (TAC NO. M92708)

Dear Mr. Bordine:

15'0 -.J-55 On May 19, 1995, the NRC issued Generic Letter 92-01, Revision 1, Supplement 1 (GL 92-01, Rev. 1, Supp. 1), "Reactor Vessel Structural Integrity."

In GL 92-01, Rev. 1, Supp. 1, the NRC requested that nuclear licensees perform a review of their reactor pressure vessel structural integrity assessments in order "to identify, collect, and report any new data pertinent to [the]

analysis of [the] structural integrity of their reactor pressure vessels (RPVs) and to assess the impact of that data on their RPV integrity analyses relative to the requirements of Section 50.60 of Title 10 of the Code of Federal Regulations (10 CFR 50.60), 10 CFR 50.61, Appendices G and H to 10 CFR Part 50 (which encompass pressurized thermal shock (PTS) and upper shelf energy (USE) evaluations), and any potential impact on low temperature overpressure (LTOP) limits or pressure-temperature (FLT) limits."

More specifically, in GL 92-01, Rev. 1, Supp. 1, the NRC requested that addressees provide the following information in their responses:

(1) a description of those actions taken or planned to locate all data relevant to the determination of RPV integrity, or an explanation of why the existing data base is considered complete as previously submitted; (2) an assessment of any change in best-estimate chemistry based on consideration of all relevant data; (3) a determination of the need for the use of the ratio procedure in accordance with the established Position 2.1 of Regulatory Guide 1.99, Revision 2, for those licensees that use surveillance data to provide a

~~~i~-~o~ th~-~Pv __ ~nt~g~ity ~va~~~~-i-~n~-~~d-f'°\\.

(4) a wr1tten report prov1drng any newly acqu1red data as spec1f1ed-above-----l)----

(

260009 and (1) the results of any necessary revisions to the evaluations of RPV integrity in accordance with the requirements of 10 CFR 50.60, 10 CFR 50.61, Appendices G and H to 10 CFR Part 50, and any potential impact of the LTOP and FLT limits in the technical specifications, or*

(2) a certification that previously submitted evaluations remain valid.

Revised evaluations and certifications were to intlude consideration of

  • Position 2.1 of-Regulatory Guide 1.99, Revision 2, as applicable, and any new data.

The information in Reporting Item {1} was*to*be submftted within 90 days of the issuance of the GL.

Th~ information in Reporting Items.

(2) through (4) was to be submitted.within 6 months of the issuance of the GL.*

Consumers Power Company {CPCo} submitted the information requested in Reporting 1tem jl} on August _17, 1995, and requested i~ Reporting*Ite~s (2) through (4) on November 17, 1995.

By letter dated December 20, 1995, you submitted typographical corrections to the* Nov.ember 17, 19~5, submittal.

Your submittals provided new RPV data to the staff for the Palisades Plant.

However; you indicated in your response to Generic Letter 92~1, Revision l, Supplement 1, that the revised data does not imp act the L TOP and P-T Limits defined in the Palisades Technical Specifications or.compliance with the PTS and. USE regulations (10 CFR 50.61 and 10 CFR Part 50, Appen_dices G and *H,

  • respectively).
  • You therefore.indicated that the previously submitted

~evaluations for Palisades remain valid~ Stibsequent tri your responses to th~

  • nGL supplement; you sub~itted ~n updat~d reactor vessel. fluence calculation and revised PTS s*~reening ev~luation PY letter dated April 4, 1996. *The *staff is~ued an interim evaluation *of this submittal ori December 20, 1996, *and is crintinuing ~o ~eview portions. o~ the April 4, 1996, ~ubmitta).
  • . *,S.ince the requested* information has bee.n provided, the staff' is closing out
      • TAC No; M92708 for Palisades.-*.Hqwever, the staff will revtew the new RPV data
    • -at*a late_r date.* Further,more, the staff*has *also-noted that the Owners
