By letter dated April 8,
1991 (GNRI-01/00074), the St af f requested additional informat ion in order to complete its review of our proposed change to the Grand Gulf Nuclear Station (GCNS) Operating License dated March 15, 1941 (GNRO-91/00047).
The proposed change requested that GGNS Technical Specif Icat ions (TS) he revised in accordance with Generic Letter 91-01.
These revisions would relocate the suiveillance specimen wit hdrawal schedule in TS Table 4.4.(1.1.3-1 to the GGNS Updated Final Saf ety Analysis Report.
in response t o the Staf f request, the attachment to this letter provides our response to the questlens transmitted April 8, 1991.
The Staff requested a rerponse wit.hin 30 days of receipt of their request; however, GGNS requested and rec eived an ext ension t o respond by May 24, 1991 from the NRC GGNS Project Manager on May 14, 1991.
If you require addit ional information, please advise.
Yours t ruly.

Attachment to GNRG-91/00091 NRC REQUEST _No._1:
Generic hett er (Gh) 4 01, " Guidance for the Removal of the Withdrnwal Schedule for Reactor \\ esse 1 Mat erin 1 Specimens from Technica1 Specifications," allows t emoval of t he surveillance specimen wit.hdraval schedule f rom the Technica1 Speci ficnt ions (TS) and telocatinn of the schedule to the Updated Final Safety Analysis Report (UFSAR).
Ilow ev e r,
chat.ges to the schedule cannot be mnde pursunut to 10CFR50.59 because Stat ion 11.11. 3 of Append ix 11 t o 10CFR Part 50 requires NRC approval of any changes t o t he schedule prior t o implementation.
In your submittal and in the proposed revision to the Technical Specifications, you did not-Indicate how NRC approval of future changes to the withdrawnl schedule would be requested and documented.
provide a statement in the proposed i
TS Bases sect ton to indicate that written NRC approval will be obtained for any change to the withdrawal schedule, prior to incorporntlon into the UFSAR.
G.GNS _ RESPONSE No _1:
As discussed with the NRC Staff on May 14, 1991, providing a Bases discussion of how NRC approvnl of future changes t.o t he spec imen wit hdrawal schedule would be requested and documented is redundant to existing regulations and runs counter to thn intent of Gb 91-01 to remove redundancy.
Grand Gulf Nuclear Station (GGNS) will maintain the NRC-approved version of the specimen withdrawal schedule in the UFSAR, in accordance with applicable regulations.
NRC_ REQUEST No._2:
The guidance provided in Gb 91-01 st ates that the surveillance requirements must indicate that the reactor vessel material specimens "shall be ramoved and examined to determine changes in material properties as required by 10CFR Pa rt. 50, Appendix H."
Your proposed TS 4.4.6.1.4 omitted the above underlined phrase.
P rov ide a revision to your proposed TS to include the underlined phrase.
GGN._kESp0NSE No.__2:
S GGNS TS Surveillance Requirement 4.4.6.1.4 presently rends:
The renctor vessel material specimens shall be removed and examined ns a function of time and TilERMAh POWER as required by 10CFR50, Append ix H.
Substitution of the phrase "... to determinc changes in material properties..." is equivalent in meaning to the existing surveillance requirement.
Although we believe that such a change is unnecessary and wasteful of 1icensee and NRC resources, we have attached a proposed surveillance requirement in accordance with your direction.
Since this change is synonymous with the existing requirement, the previously submi t.ted (GNRG-91/00047, dated March 15, 1991) No Significant Hazards Considnration ann!yses is unnffected by the change.
