Request for Additional Information La Salle County Station, Units 1 & 2 Docket Hos. 50-373 and 50-374
'420.0 QUALITY ASSURANCE BRANCH 423.42 It has come to our attention that although some applicants had committed to Regulatory Guide 1.68, they did not intend to conduct full-load tests of some 4160-480 volt transformers supplying power to vital buses.
Your test description in FSAR Chapter 14 does not contain sufficient detail for us to determine if you intend to conduct such a test.
It is our position that full-load tests of vital buses must be conducted including all sources of power supplies to the buses. Modify your test description to indicate that this testing will be conducted in accordance with Regulatory Guide 1.68.
State your intent to comply with our requirements.
