SUMMARY

OF OPERATIONS for MARCH 1981 On Nrch 1,1981, the Unit was off line for tube plugging the "B" 4th Point Feedwater heater, installing a bypass around the 4th point heater, and re-placement of the RCIC inboard isolation valve (M01301-16). The reactor was brough critical at 1331 hours0.0154 days <br />0.37 hours <br />0.0022 weeks <br />5.064455e-4 months <br /> on Nrch 10 and the generator was synchronized to the grid at 0132 hours0.00153 days <br />0.0367 hours <br />2.18254e-4 weeks <br />5.0226e-5 months <br /> ~on March 11, and unit returned to 100.' power.

The unit operated on 100% with minor trimhg for condenser delta t. - pe rature and control rod exercises until March 21 when power was reduced to 50% for a

- condenser backwash. The unit was returned to 100% and remained there until March 28 when power was again reduced to 50% for another backwash. Following the backwash, the unit was returned to 100% and remained there for the rest of March.
