MONTHLY OPERATING EXPERIENCE UNIT 1 JULY 1997 July 1 The Unit began the report period shutdown in Mode 3 to resolve seismic qualification concerns with the main feedwater flow transmitters.

July 2 At 1729 hours0.02 days 0.48 hours 0.00286 weeks 6.578845e-4 months , the Unit began to cooldown to Mode 5 to perform a design change l to the main feedwater flow transmitter control circuitry and for needed modifications l to pipe supports on the excess letdown piping.

July 3 Mode 4 was entered at 0923 hours0.0107 days 0.256 hours 0.00153 weeks 3.512015e-4 months and Mode 5 was entered at 1830.

July 4 While the Unit remained in Mode 5, a median control selector switch was installed as through a corrective action to resolve the main feedwater flow transmittec:, seismic

- July 28 qualification concerns, and modifications to the excess letdown piping were completed. Additional activities involved repairing and modifying additional pipe supports to the Charging and Volume Control System's normal and excess letdown lines, and also completing modifications to three containment isolation check valves.

July 29 Following completion of the above, the Unit began to heatup and entered Mode 4 at 1649 hours0.0191 days 0.458 hours 0.00273 weeks 6.274445e-4 months .

July 30 The Unit continued to heatup and entered Mode 3 at 0028 hours3.240741e-4 days 0.00778 hours 4.62963e-5 weeks 1.0654e-5 months .

July 31 Mode 2 was entered at 0305 hours0.00353 days 0.0847 hours 5.042989e-4 weeks 1.160525e-4 months and the reactor was taken critical at 0443 hours0.00513 days 0.123 hours 7.324735e-4 weeks 1.685615e-4 months .

Mode I was entered at 0610 hours0.00706 days 0.169 hours 0.00101 weeks 2.32105e-4 months . The Main Unit Generator was synchronized to the electrical grid at 1059 hours0.0123 days 0.294 hours 0.00175 weeks 4.029495e-4 months and power was escalated to approximately 30%

output. The Unit remained at approximately 30% output through the end of the report period.

Also note that following entry in Mode 2, the Automatic Rod Control Position Deviation Monitor, although- still functional, was not considered operable per Technical Specifications. The limiting condition for operation as specified in the

- Technical Specifications was met because the deviations between the indicated rod positions were verified to be within their 12 step limits by obtaining analog / digital rod positions at least once every 4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months . In addition, Control Rod H-2 was also considered inoperable. The limiting condition for operation as specified in the Technical Specifications was met by reading the detector primary voltage every four hours.
