Sumnary of operating Experience for Unit 1 Byron Unit 1 began comnercial operation at 0000 on September 16, 1985. Currently the Unit is restricted to 92% power due to excessive Steam Generator moisture carryover.
The Unit began this reporting period returning to 92% power after an administrative reduction due to a Solid State Protection System switch failure. The Unit re:nained at power until Sept. 22nd, when power was reduced to approximately 50% in order to facilitate repairs on a Feedwater Pump. The Unit was returned to 92% power and remained so until Sept. 26th. On the 26th the Unit was administrative 1y shut down in order to effect repairs on the Containment Floor Drain Sump level instrumentation. The Unit was return to power en the 29th and remained at power through the end of the reporting period.

Document Control Desk Gentlemen:
On September 16, 1985, Byron Unit One completed its startup program successfully and has been made available for regular production of electricity.
Enclosed for your information are two performance Reports, the first covering Byron Nuclear Power Station for the period September 1 through september 15, 1985, and the second covering the period september 16 through September 30, 1985.
Please note in Section B item 9, of the first report the final " YEAR TO DATE" and " CUMULATIVE" numbers have been adjusted to reflect calculations using the finalized reactor coolant average temperature.
Very truly yours,
