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.
