McGUIRE NUCI. EAR STATION RESPONSE TO DEVIATION 50-369/85-39-01 & 370/85-40-01 Deviation McGuire FSAR Section 6.4.3 and Table 6.2.3-4 stipulate that inplace testing of the Control Room Area Ventilation Systems (CV) were in compliance with Regulatory Guide 1.52 (Revision 2, March 1978) which in turn obligates the licensee to ANSI N510-1975.
Contrary to those commitments, a review of completed preoperational tests performed on McGuire Control Room Area Ventilation Trains A and B reveal _ d that Regulatory Guide 1.52 and/or ANSI N510-1975 were not adhered to in that the air-aerosol uniformity tests were not performed as specified.
This deviation is applicable to Units 1 and 2.
Response
In response to the notice of deviation regarding the lack of preoperational tests for Control Room Area Ventilation Trains A and B, a temporary test was written and conducted on 11/6-7/85 to determine air / aerosol mixing unifo rmity. Results of this testing met the acceptance, and have been previously reported. McGuire Nuclear Station was in full compliance as of 11/7/85.
The missing preoperational tests resulted from a miscommunication between station and vendor testing personnel, regarding applicable revisions of ANSI N510. Preoperational tests will be required again only in the case of system modifications, and testing will be performed by Duke personnel. Through our awareness of FSAR commitments, further deviations will be avoided.
