.I 1.- Monthly Report for Braidwood Unit 1

<A. S.umAIy_nL_QPMAting_ExpeI.12nCB Braidwood Unit 1 operated routinely from June 1 through June 18, 1991 when the unit reduced power to inspect a condenser water box for tube leaks. After completion of repairs on June 20, 1991 the unit returned to normal operation until June 22, 1991 when power was again reduced to inspect and repair tubes in another condenser water box. The unit returned to full power on June 24, 1991 and operated routinely for the remainder of the month.

ATTACHMENT Revision to the Offsite Dose Calculation Manual (ODCM)

Revisions to the Offsite Dose Calculation Manual (ODCM) are reportable to the NRC in accordance with Braidwood Station's Technical Specificaticns.

Braidwood Station's Radio; ogical Environmental Monitoring Program (REMP) has been updated to identify a new surface water sampling location, sample point BD-25, Enkakee River upstream of discharge 9.6 mi E of t%

station. This sample point was added to eliminate the posotbility of the upstream sample being influenced by Braidwood Station discharge water.

The change does not reduce the accuracy and reliability of the aetroint determination or model methodology, l
