- STUCK OPEN DOOR COULD PREVENT THE SBGT SYSTEM FROM DRAWING A VACUUM IN AUX BLDG -
At 1440 CDT on 08/11/00, the licensee prepared a condition report to identify that personnel access door #PW-95-02 between the auxiliary and turbine buildings had been stuck open about 8 inches for approximately 18 minutes beginning at 2250 CDT on 08/10/00. A faulty door assist device lever arm prevented closure. This condition could have resulted in a loss of function of the secondary containment since the standby gas treatment (SBGT) system may not have been able to draw down pressure in the auxiliary building to the required vacuum. The door device has been repaired and the door is now closed properly.
The licensee notified the NRC Resident Inspector.

- CONTAINMENT MONITORING SYSTEM INOP DUE TO DRAIN LINES FILLING WITH CONDENSATION -
On 08/09/00, the licensee declared both divisions of the containment monitoring system (CMS) inoperable after engineering department personnel determined that during a design basis loss of coolant accident, the return lines to the suppression pool would fill with condensation which would result in the system being unable to perform its safety function,
At 1805 on 08/11/00, the licensee recognized that with both division of the CMS inoperable and the post accident sampling system previously inoperable, this event is reportable to the NRC in accordance with 10CFR50.72(b)(2)(iii)(D).
At 1935 on 08/11/00, this issue no longer affects the operability of the CMS. The licensee made procedure enhancements to the Unit 2 Emergency Operating Procedures to periodically drain the condensation that would accumulate in the return lines during Post Accident Conditions.
The licensee plans to notify the NRC Resident Inspector.
