83-01 (A) (1) At 2115 on January 3, 1983 with the Unit at 100% power a unit rampdown to off-line was commenced due to Hydrogen leaks at the Main Generator. The generator was taken off-line at 0305 on January 4,1983, with the reactor maintained critical. At 1044 on January 5, 1983, a Reactor Trip due to Steam Generator Low-Low level occurred. The unit was stabilized in Mode 3 (Hot Standby) while awaiting completion of repairs to the Main Generator. Repairs to the Main Generator Hydrogen system were completed and the reactor reached criticality at 1325 January 7, 1983. The unit was placed on-line at 0257 and reached 100%

power at 2300 January 8, 1983.
