SUMMARY

- JUNE 1983 dllli l The unit started the month at apprcximately 60% full power while going through power escalation frcm a shutdown which had occurred the previous month.

This unit attained 100% full power operation on June 7 and operated there until June 9.

At 1349 hours0.0156 days <br />0.375 hours <br />0.00223 weeks <br />5.132945e-4 months <br /> on June 9, the unit tripped on loss of both main feecwater (MFW) pumps.

The trir was caused by a spurious AC signal sent to the suction pressure indicators.

The reactor was brought critical again on June 11 at 1203 hours0.0139 days <br />0.334 hours <br />0.00199 weeks <br />4.577415e-4 months <br />, and the turbine was tied to the grid at 1754 hours0.0203 days <br />0.487 hours <br />0.0029 weeks <br />6.67397e-4 months <br />.

The unit attained 100% full power operation on June 14 and operated there until June 16.
