==SUBJECT:==
OU 4GE GREATER THAN 72 HOURS On September 30, 1988, the licensee performed a special test of the main steamline ',olation valve (MSIV) solenoid operated valves (SOV) as described in NRC Information Notice 88-43, "Solenoid Valve Problems." Two out of eignt S0Vs failed. The failure of the solenoids on the B and C inboard MSIVs would have prevented fast closure of those valves. The redundant outboard MSIVs operated as designed. As a result of these test results, the licensee comenced a reactor shutdown on September 30, 1988. The plant will be shutdown for between 4 to 7 days to perform maintenance and corrective o.tions on the MSIV S0Vs, recirculation pump seals, and other items.
Neither the licensee nor the NRC plans to issue a press release.
The state of Louisiana will be informed.
Region IV first received notitication of this occurrence by telephone from the Senior Resident Inspector at 2:45 p.m. on September 30, 1988.        Region IV has informed NRR, SP, and PA.
