Dear Mr. Parker:
SUBJECT:
STAFF POSITION: REGULATORY GUIDE 1.68, ' INITIAL TEST PROGRAMS FOR WATER-COOLED REACTOR POWER PLANTS" (McGuire Nuclear Station, Units 1 and 2)
It has come to our attention that some applicants did not intend to conduct con-fimatory tests of some distribution systems and transformers supplying power to vital buses as required by Position 3 of Regulatory Guide 1.68, and more specifi-cally by Part 4 of the staff position on degraded grid voltage. Part 4 of the
. degraded grid voltage position states as follows:
"4.
The voltage levels at the safety-related buses should be optimized for the full load and minimum load conditions that are expected throughout the anticipated range of voltage variations of the offsite power source by appro-priate adjustment of the voltage tap settings of the intervening transfomers. We require that the a Q uacy of the design in this regard be verified by actual measurement and by correlation of measured values with analysis results. Provide a description of the method for making this verification; before initial re. actor power operation, provide the documentation required to establish that this verification has been accomplished."
Your test description in FSAR Chapter 14 does not contain sufficient detail for us to detemine if yau intend to conduct such a test.
It is our position that confimatory tests of all vital buses must be conducted including all sources 8 0022 80QQ}
