ENCLOSURE 2 NOTICE OF DEVIATION Georgia Power Company Docket Nos. 50-321 and 50-366 Hatch Units 1 and 2 Licensee No. DPR-57 and NPF-5 The following deviation was identified during a Nuclear Regulatory Commission (NRC) inspection conducted on May 21 - June 24, 1988.
Unit 2 Final Safety Analysis Report (FSAR), Section 9.4.5.4, "Tests and Inspections " states that all components of the diesel generator building heating and ventilation system were preoperationally tested before placing the system in service and have been periodically tested thereafter.
FSAR Table 9.4-10. "Diesel Generator Building Heating and Ventilation System Failure Analysis," lists exhaust fans, heaters, and louvers as components of the system and describes malfunctions of the system as failures of the louvers, heater or centrols, and fans or controls.
Contrary to the above, on June 8,1988, the inspector found various thermostat settings for like controls of the diesel generator room exhaust fans and heaters and switchgear room exhaust fans.
One section of the two-section, wall-mounted, air-inlet louvers to switchgear rooms 2G and 2F were found to have failed in the shut position and one louver section for room 2E was partially shut.
A review of the instrument calibration and surveillance test tracking master listing found that the thermostat controls are not periedically tested. No instructions could be found that checks the dampers ability to open.
