Operational Summary for December, 1983 The month commenced with the unit at 77% power as limited by fuel de-pletion. On 12/2/83, the "B" train of feedwater heaters were bypassed and power was reduced to 67%. Two in series secondary containment damp -

ers were found inoperable on 12/5/83, and a plant shutdown was , initiated.

The dampers were immediately repaired, tested and the shutdown secured (Reference LER 83-062/03L-0). Steady state operation continued until 12/10/83, when the unit was removed from service for refueling and re-circulation pipe inspection.

Safety Relief Valve Challenges Month of December, 1983 Requirement: T.M.I. T.A.P. II.K.3.3 Reason: No safety / relief valve challenges occurred during the month of December, 1983.
