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. j I.

SUMMARY

OF OPERATING EXPERIENCE The unit began the month of April, 1996, in Mode 4. The unit was in process of start-up following 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 plant reached Mode 1, 100%

powar at 0430, April 11, -1996. The unit operated at approximately 100% power until commencing turbine / generator load decrease at 2106, April 19, 1996; 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 rasntered 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 through the end of April, 1996.
