• TXX-89561 August 9, 1989 Page 2 of 2 As a result of discussions between TU Electric and the NRC prior to and during the preoperational and startup testing audit conducted June 20-22, 1989, Unit I testing was rescheduled for completion by Unit I fuel load.

Reference 2 provides a discussion of the loss of instrument air tests for accumulators.

These tests encompass the cyclic testing of safety-related valves and accumulators. The schedule for Unit 2 remains unchanged.

Sincerely, William J. Cahill, Jr.
