SUBJECT:

2 for Unit 2, Failure o f ASC0A Deluge Valves AECM-84/2-0009

Reference:

AECM-84/0212, 4/6/84 On March 19, 1984, Mississippi Power & Light Company notified Mr. P.

Fredrickson, of your office, of a Reportable Deficiency at the Grand Gulf Nuclear Station (GGNS). The deficiency concerns the. failure of two Automatic Sprinkler Corporation of America ( ASCOA) deluge valves to open upon receipt of an actuation signal.

Although the fire protectica system deluge valves were procured and installed as non-safety related equipment, the fire protection system for the diesel generator building is included in the MP&L Operational Quality Assurance Program. Due to the possible ef fect on safety related equipment in the diesel generator rooms, MP&L has concluded that the failure of the diesel generator room deluge valves is reportable under the provisions of 10CFR21 for Unit 1.

Determination of reportability for this deficiency for Unit 2 is still under way at this time. We expect to submit a Final Report on Unit 2 by June 14, 1985.

No ASC0A deluge valves have bean received for use on Unit 2. Our Architect / Engineer has requested Automatic Sprinkler Corporation of America to inspect all Grand Gulf Unit 2 deluge valves for the noted deficiency prior to shipping. Also, an inspection will be performed by our Architect / Engineer once the valves arrive on site for use on Unit 2. If any deficiency is found, a safety evaluation will be performed at that time.
