ENTERGY OPERATIONS. INC.. ET. AL.

i GRAND GULF NUCLEAR STATION. UNIT 1 1

DOCKET NO. 50-416 i

l The following questions are based on the licensee's proposed exemption to 10 CFR 70.24(a) in its submittal of July 15, 1996.

j 1.

Provide a list of the areas at Grand Gulf, Unit I which contain criticality monitors that conform to 10 CFR 70.24(a), the activit.es conducted in these areas with special nuclear material (SNM), and the amount of SNM that could be in these areas. Describe the controls, if any, which limit the SNM in these areas.

2.

Describe the procedural controls and/or physical constraints which exist to preclude inadvertent removal of unirradiated fuel from Nuclear Regulatory Commission (NRC)-approved packaging in areas where criticality i

monitors are not provided.

i i

3.

Discuss the maximum U-235 fuel enrichment (or k-infinity) of fuel analyzed for storage in the fresh fuel racks at Grand Gulf, Unit 1, and the effects of accidental flooding or low-density optimum moderation conditions on potential criticality in storage. Discuss the maximum j

enrichment which is accounted for in the NRC-approved packaging.

4.

Discuss the administrative controls mentioned in Section 9.1.1.3.1 of the i

Updated Final Safety Analysis Report that are used to prohibit the introduction of sources of optimum moderation to the stored fresh fuel.

5.

Discuss how this exemption would remain valid if a future fuel enrichment increase was contemplated for Grand Gulf Unit 1.

The Technical Specifications for Unit I do not limit the enrichment of the fuel at the l

site, i

6.

Discuss that radiation monitoring remains available to meet the requirements of GDC 63 for fuel storage areas.
