I. Monthly Report for Braidwood Unit 1 |

IA. Summary of Ooeratina Experience

,

The unit entered the month off line due to a continuation |C of the first refueling outage. The refueling outage was ,

completed during the month and the unit went critical onDecember 11, 1989. The unit was synchronized to the grid i

on December 15, 1989. Reactor power continued to increase 1

through the end of the month as post refuel testing was' '

completed.|

On this form list the average daily unit power level in MHe-Net for eachday in the reporting month. Compute to the nearest whole megawatt.

- These figures will be used to plot a graph for each reporting month.Note that when maximum dependable capacity is used for the net electricalrating of the unit there may be occasions when the daily average powerlevel exceeds the 100% line (or the restricted power level line). Insuch casos the average daily unit power output sheet should be footnotedto explain the apparent anomaly.
