FEBRUARY 1997 i

i February 1 The Unit operated at a nominal value of 100% output for the entire report period.

! through However, at 2240 hours0.0259 days <br />0.622 hours <br />0.0037 weeks <br />8.5232e-4 months <br /> on 02/19/97, the Unit initiated a plant shutdown per

. February 28 Technical Specifications due to both Emergency Diesel Generators being considered 4 inoperable. At 2246 hours0.026 days <br />0.624 hours <br />0.00371 weeks <br />8.54603e-4 months <br /> with Turbine load reduced by approximately 10 MWe, i

one of two Emergency Diesel Generators was returned to service and the required Technical Specification shutdown was aborted. Turbine load was returned to full ' ,

output and the second Emergency Diesel Generator was subsequently returned to i service at 0700 hours0.0081 days <br />0.194 hours <br />0.00116 weeks <br />2.6635e-4 months <br /> on 02/20/97.

' 1 In addition to the above, the following events which also occurred during the report period are being reported as required by Technical Specifications.

- February 1 The Automatic Rod Position Deviation Monitor, although still functional, was not through considered openble per Technical Specifications. The limiting condition for February 28 operation as specified in the Technical Specifications was met because the deviations between the ind:cated 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 <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />.
