MONTHLY OPERATING EXPERIENCE j

UNIT 1 JUNE 1995 t

June 1 The Unit operated at a nominal value of 100% output.

June 2 The Unit continued to operate at a nominal value of 100%

output, however, at 1430 hours0.0166 days <br />0.397 hours <br />0.00236 weeks <br />5.44115e-4 months <br /> the main unit turbine controls automatically transferred from a partial arc to. a full arc admission mode resulting in the loss of approximately 30 MWe.

Following initial - troub eshooting, the controls were ' returned to the partial are mode at 1536 hours0.0178 days <br />0.427 hours <br />0.00254 weeks <br />5.84448e-4 months <br /> and the 30 MWe were recovered.

June 3 The Unit continued to operate at a nominal value of 100%

output, however, at 0829 hours0.00959 days <br />0.23 hours <br />0.00137 weeks <br />3.154345e-4 months <br /> the above transfer automatically occurred again resulting in a loss of approximately 30 MWe.

The #2 Mam Turbine Governor Valve was suspected as the cause for the auto-transfers.

At 1419 hours0.0164 days <br />0.394 hours <br />0.00235 weeks <br />5.399295e-4 months <br /> output was reduced to approximately 95% in order to troubleshoot the #2 Governor Valve.

The initial investigation revealed no problems with the

  1. 2 Governor Valve.

At 1810 hours0.0209 days <br />0.503 hours <br />0.00299 weeks <br />6.88705e-4 months <br />, the turbine controls were returned to the partial arc mode and output was increased to a nominal value of 100%.

June 4 The Unit continued to operate at a nominal value of 100%

output, however, at 1802 hours0.0209 days <br />0.501 hours <br />0.00298 weeks <br />6.85661e-4 months <br /> the above transfer automatically occurred again resulting in a loss of approximately 30 MWe.

The Unit was left in the full arc admission mode to avoid further transients.

June 5 The Unit continued to operate in the full arc admission mode at a nominal value of 100% output, but with a loss of i

approximately 30 MWe due to problems with the #2 Governor Valve controls.

June 6 At 1211 hours0.014 days <br />0.336 hours <br />0.002 weeks <br />4.607855e-4 months <br />, output was reduced to approximately 98% to support closing' the #2 Governor Valve for troubleshooting and repair.

June 7 The Unit continued to operate at approximately 98% output for troubleshooting and repair of the #2 Governor Valve controls.

+

June 8 Following repair of the #2 Governor Valve controls, turbine controls were returned to the partial are mode and output was returned to a nominal value of 100% at 2100 hours0.0243 days <br />0.583 hours <br />0.00347 weeks <br />7.9905e-4 months <br />.

MONTHLY OPERATING EXPERIENCE UNIT 2 JUNE 1995 June 1 The Unit operated at a nominal value of 100% output.

through June 28 June 29 The Unit continued to operate at a nominal value of 100%

output.

At 1754 hours0.0203 days <br />0.487 hours <br />0.0029 weeks <br />6.67397e-4 months <br /> an electrohydraulic fluid leak was discovered on the #1 Main Turbine Governor Valve.

Timely isolation of the leak necessitated a

load - rejection to approximately 64% output. The Unit remained stabilized at 64%

output for the remainder of the day.
