SUMMARY

Tha following report highlights the operating experience of Wolf Creek Generating Station for the month of April, 1996. This report is being provided pursuant to Technical Specification 6.9.1.8.

I.

SUMMARY

OF OPERATING EXPERIENCE The unit began the month of April, 1996, in Mode 4. The unit was in process of start-up procedures from Refuel VIII. The unit entered Mode 3 at 2312, April 2, 1996; Mode 2 at 2315 on April 5, 1996, and Mode 1 at 0550 April 7, 1996. The generator was synchronized to the grid at 1113, April 7, 1996. The plant reached Mode 1, 100% power at 0430, April 11, 1996. The unit operated at approximately 100% power until commencing turbine / generator load decrease at 2106, April 19, 1996. At 0536, April 20, 1996, the gtnerator output breakers were opened, and at 0950, April 20, 1996, the unit was in Mode 2, approximately 5% power, to balance the turbine. Upon completion of turbine balancing work, the unit commenced increasing power. The unit reentered Mode 1 at 1458, and the generator was synchronized to the grid at 2145, April 20, 1996. The unit reached Mode 1, 100% power, at 0000, April 22, 1996, and remained at that level t.hrough the end of April, 1996.
