SUMMARY

OF OPERATING EXPERIENCE DOCKET NO. 50-251 UNIT Turke Point 4 DATE Januar 15 1992 COMPLETED BY R. A. Tierne TELEPHONE 305 246-6970 REPORT MONTH December 1991 On December 10, 1991, after the failure of an output card on the 4A sequencer, the plant was shutdown due to the inoperability of the sequencer. This event is discussed in detail in LER 251 91-007.

During an inspection of the reactor vessel on December 11, a conoseal was found to have some evidence of leakage. The conoseal was repaired. On December 18, during the startup process, a hold at less than 30% power occurred due to secondary system water chemistry and a turbine overspeed test.
