SUMMARY

OF OPERATING EXPERIENCE 1-1 to 1-30

. 1-31 UNIT TWO JANUARY, 19 80 Unit Two operated during the month at an avera*ge power level of 699 MWe.

On January 30 at 1045, the unit was

~nadvertently manually scrammed upon receiving a half-scram signal on RPS Channel B.

The unit was placed on line at 0104 on January 31 and operated for the re-mainder of the month, resulting in a capacity factor of 86.6% for the en-tire month.

SUMMARY

OF OPERATING EXPERIENCE UNIT THREE JANUARY, 1980 1-1 to 1-31 The unit operated continuously during the.entire rrionth at an aver-age power level of *

.. 519 MWe, with a capacity factor of 65.1%.
