OFFICE OF NUCLEAR REACTOR REGULATION WEEKLY ITEMS OF INTEREST (Week Ending April 7, 1980)
HADDAM NECK PLANT On March 27, 1980 while operating at 100% power the Haddam Neck Plant experienced a containment isolation signal, a safety injection signal and a reactor scram.
The cause was believed to be an equipment instal-lation error, i.e., a short of contacts during installation of containtient isolation valve control relays in response to Short Term Lessons Learnad requirement 2.1.4.
~
All systems operated as designed and the plant stabilized in a normal but standby condition.
The plant was brought back on line the following morning after the licensee completed an investigation of the event.
I&E will. followup on any additional actions by the licensee.
Plum Brook Test Reactor NASA has requested authorization to dismantle the 60 Kit Plum Brook Test Reactor and the 100 W.4t Mock-Up Research Reactor.
Dismantling plans and environmental plans have been provided in support of these requests.
These reactors have been shutdown since 1973 and have a possession only license.
Vermont Yankee An estimated 1000 people demonstrated peacably Sunday, 3/30/80, in front of the Vermont Yankee plant.
About 75 were arrested because they were blocking the gate at shift change time when the 3/31/80 graveyard shift came on duty, and about another 75 were arrested for the same reason when the 8-4 shift came on duty this norning.
Vermont Yankee shut down 3/31/80 to change control rod patterns and repair a steam leak in the turbine steam seal regulator system. The plant was back in operation April 2,1980.
Humboldt Bay The Atomic Safety and Licensing Board has scheduled a prehearing conference for June 3,1980 in Eureka, California to consider the request of Pacific Gas and Electric that proceedings be held in abeyance until October 1,1980.
'b 2-Pilarim Unit 1 Strikers picketed all gates at Pilgrim Nuclear Power Station commencing 7 A.M.
on April 1, and ending about 7 A.M. on April 2,1980.
Union workers including reactor operators honored the picket lines.
Non-union personnel were not affec ted.
