SUMMARY

OF OPERATING EXPERIENCE UNIT ONE MARCH, 1981 3-1 to 3-31 Unit One was shutdown for the entire month, awaiting license approval for the chemical cleaning.

Major work scheduled to be completed following chemical cleaning is as follows:

HPCI installation for ECCS upgrading, equip-ment upgrade to IEEE 279, major in-service inspection, and refuel.

SUMMARY

OF OPERATING EXPERIENCE

  • UNIT TWO 3-1 to 3-31 MARCH, 1981 Unit Two was shutdown for the entire month for its scheduled refueling and equipment overhaul outage.

Major work included torus modification, CRD replace-ments, and turbine overhaul.

SUMMARY

OF OPERATING EXPERIENCE UNIT THREE 3-1 to 3-31

MARCH, 19~1 Unit Three entered the month operating at a power level of* 802 MWe and operated continuously throughout the month (ex-cept for normal weekend surveillances),

reach_ing a power level of 827 MWe, with a capacity factor of 97.32% and an availa-bility' of 100.0%.
