ATTACHMENT GINNA STATION, UNIT I DOCKET NO. 50-244 RE(VEST FOR ADDITIONAL INFORMATION REGARDING 24-MONTH SURVEILLANCE INTERVALS (TAC NO. M92969)
The following questions apply to both the AC power (Offsite Power) and the Emergency Diesel Generator.systems
(
Reference:
Surveillance Requirements 3.8.1.6; 3.8.1.7; 3.8.1.8 and 3.8.1.9).
Is the change (i.e.,
proposed extension in the surveillance interval) consistent with manufacturer's recommendations?
Given that the licensee has consulted the equipment manufacturer were there any additional measures (e.g.,
interim inspections, added preventative maintenance activities) recommended and if so, what was the disposition of those recommendations?
2.
3.
4.
Did the licensee evaluation include a review of the corrective and preventative maintenance activities now in place in order to assess whether the proposed extension of the surveillance interval will lead to any deterioration in the system or components?
Did the licensee evaluation include a review of the maintenance history to determine whether there were any performance-related indications which would suggest that the proposed extension of the surveillance interval could cause deterioration in the system/component condition or performance?
What additional measures have been taken to address the subject indications?
Did the licensee evaluation include a review of the operating surveillance results and history for the subject systems and components to ensure that the proposed extension will not negatively affect any corrective action activities or the investigation of any long term operating problems?
Discuss any failures involving the subject component/system as well as whether there would be any increase in failure rate as a result of the proposed extension of the surveillance interval.
