SUBJECT:

Grand Gulf Nuclear Station Unit 1 Docket No. 50-416 License No. NPF-29 File: 0260/0840/L-860.0 Technical Specification Amendment Effective Dates AECM-85/0396

Reference:

1) Letter from Elinor G. Adensam to Mr. J. B. Richard dated September 18, 1985

2) Letter from Elinor G. Adensam to Mr. J. B. Richard dated Octrher 21, 1985 Mississippi Power & Light (MP&L) was requested by the referenced letters to notify the Nuclear Regulatory Commission (NRC) of the effective date of certain technical specification changes. MP&L was also requested to notify the NRC of equipment installation delays beyond the Fall Outage scheduled for October and November of 1985 associated with the reference technical speci-fication changes.

Amendment 4 to Facility Operating License NPF-29, provided changes to the Containment and Drywell Isolation Valves table 3.6.4-1 and the Primary Containment Penetration Conductor Overcurrent Protection Devices table 3.8.4.1-1 and have an effective date of November 7, 1985. Changes to the Fire Detection Instrumentation table 3.3.7.9-1.c.16 have been administratively implemented but cannot be made effective in the technical specifications until work has been completed to make effective changes to 3.3.7.9-1.d.1.

Both of these changes affect page 3/4 3-87 of the technical specifications, and will be made effective before startup after the first refueling outage.

Amendment 6 to Facility Operating License NPF-29, provided changes to unit organization, control rod scram accumulators, and fire detection instrumentation and were made effective immediately upon receipt. Changes to the primary containment penetration conductor overcurrent protection devices, table 3.8.4.1-1, and electrical power systems, 4.8.1.1.2.d.8.a and 4.8.1.1.2.d.16 will be made effective before startup after the first refueling k out>8e- e3121eO211eS12g;1, ,

AECM-85/0396 Page 2 MP&L.will notify the NRC within 30 days of the effective date of the delayed technical specification changes.

MP&L believes this method of providing effective dates for operating license amendments associated with design changes has greatly increased our

.iflexibility to plan, schedule and implement work during planned outages.
