INITIAI. TEST PROGRAM - BYRON 2, BRAIDWOOD 1 AND 2 By letter dated June 23, 1986, you requested that one Startup Test be modified and that five Startup Tests be eliminated in the Startup Test Program for Byron 2 and Braidwood I and 2.

However, the elimination of shutdown from outside control room test and loss of offsite power test is not acceptable; these two tests should be done on all three units.

Enclosure 2 is a request for additional information based on changes made in FSAR Amendment 47. Please provide response to these questions within 30 days of the date of this letter.

If any further clarification is needed, contact the Byron Project Manager, l.. Olshan, at (301)-492-4937 or the Braidwood Project Manager, J. Stevens, at (301)-492-7702.
