SUMMARY

OF OPERATING EXPERIENCE MARCH 1985 At the onset of the March 1985 reporting period, power generation continued at 69% Rated Thermal Power (32 MWe-net). At 0215 on March 10, 1985, the plant was shutdown _for the. planned refueling outage. On March 11, the reactor was taken critical 14 times for operator training and license exams.

The following Type B leakage tests were completed during March with satisfactory results.

Penetration Leakage R,a,t,e Emergency Airlock 0.259 SCFH Main Steam 0.012 SCFH Feedwater 0.065 SCFH Heating Steam and 0 Condensate Electrical Penetrations No. 4 0.088 SCFH No. 2B 0.064 SCFH No. 1B - 2B 0.0022 SCFH No. 1B - 2D 0.0180 SCFH No.1B - 6 0.0027 SCFH No.1B - 9 0.0027 SCFH Major safety-related maintenance and other activities performed during the March reporting period included defueling and refueling the reactor, facility changes due to SEP, Appendix R and TMI topics, preventive maintenance items, instrument calibrations and installation of a turbocharger on the IB High Pressure Service Water Diesel.
