==SUBJECT:==
Grand Gulf Nuclear Station Units 1 and 2 Docket Nos. 50-416 and 50-417 License No. NPF-29 File:  0260/M-181.1 High Density Spent Fuel Racks - Stress Criteria AECM-85/0352 By letter dated May 6, 1985 (AECM-85/0143) Mississippi Power & Light (MP&L) requested an amendment to License NPF-29 to allow the installation of high density spent fuel racks (llDSFR) at Grand Gulf Unit 1. During a recent conversation related to the subject amendment request, members of your staff requested that 11P&L clarify utilization of stress criteria for the IIDSFR.
MP&L's response to the staff's request is provided as an attachment to this letter.              If you have any additional questions, please contact this office.

QUESTION: Please indicate if the racks meet OT position stress criteria * .
The criteria shown in the Licensing Report (page 6-16) is from NUREG-0800.
ANSWER:    The stress factors shown in Tables 6.5 and 6.6 of the licensing report are the maximum values (maximum in space and maximum in time) which occur in the rack support feet. The stresses in the body of the rack proper are significantly smaller (almost an order of magnitude smaller). Since there is no interactior. between    T , T loads, and inertia loads (D, L, E, E') in the support feet. Ehe SRP 3.8.4 (ref. 14) and OT Position
* criteria both boil down to the following effective limits:
Loading D+L+E            Normal limits as stated in Appendix XVII-2000 D + L + E'      Normal condition stress limits increased by Appendix F-1370.
Thus, although there are differences in the stress criteria between the OT position paper and NUREG-0800,.SRP-3.8.4, Appendix D, they amount to the identical limits for Crand Gulf rack modules.
