Monthly Report for Braidwood Unit 1 A.
Summary of Ooeratina Exoerience Tne unit entered the month of June at 75% reactor power.
On June 11, the reactor was manually shut down to clean the Novable Incore Detectors. On June 14, the reactor was brought critical and on June 15 power was increased to 52%. On June 18, power was increased to-90% and again on June 28 to 98%.
The unit remained at 98% reactor power through the end of the month.

These figures will be used to plot a graph for each reporting month.
Note that when maximum dependable capacity is used for the net electr-cal rating of the unit there may be occasions when the daily average powei level exceeds the 100% line (or the restricted power level line).
In such cases the average daily unit power output sheet should be footnos d to explain the apparent anomaly.

9 II. Monthly Report for Braidwood Unit 2 A.
Summary of Oceitting Exoerience The unit entered the month of June in'Hode 3.
On June 7, the unit was synchronized to the grid and brought up to 21% power.
Subsequently, it was discovered that motor operated valve SI88098 had a non' environmentally qualified motor.
The unit was shutdown to replace the motor. On June 9, the unit was brought back on line. On June 20, while at 49% power, the unit tripped due to a surveillance on the unit auxiliary transformer overcurrent relay. On June 21 at 0033, the reactor was brought critical, however, at 0107 the reactor tripped due to a lo lo steam generator level.
By 1918 the unit was resynchronized to the grid and brought up to 16% power. On June 22 at 0033, the reactor tripped again due to a lo lo steam generator level.
By 1339 the unit was resynchronized to the grid.
On June 24, with the unit at 15% power, the reactor tripped again due to a lo lo steam generator level.
On June 25 at 0834, the unit was synchronized to the grid, however, at 1306 the unit was shut down to replace the heater drain tank rupture disk. On June 26, the unit was synchronized to the grid and over the next two days power was increased to 49% where it remained through the end of the month.
