D OTHER Specify in Abstract below or in 348 SEQUENTIAL NUMBER 2016 004 During Cycle 27 there were four periods during applicable modes when the 1 C Containment Cooler was the selected cooler for B train for a period greater than seven days:
14:19 on 5/4/2015 to 17:17 on 5/26/2015.......... 22 days 9:38 on 5/29/15 to 10:18on 6/22/2015.......... 24 days 1 :28 on 2/24/2016 to 3:37 on 7/13/2016.......... 140 days 0:52 on 8/10/2016 to 23:30 on 10/1/2016.......... 53 days There were no periods of concurrent inoperability for both the A and B trains of Containment Cooling, therefore this condition does not meet the reporting criterion for a condition that could have prevented fulfillment of a safety function required to mitigate the consequences of an accident, and is not reportable for 10 CFR 50.73 (a)(2)(v)(D).
The containment cooler system consists of two separate trains, of equal capacity, each capable of meeting the design bases. Each train is of sufficient capacity to supply 100 percent of the post accident heat removal design cooling requirements. Because there were no periods of concurrent inoperability for both the A and B trains of Containment Cooling, this condition did not significantly degrade plant safety, and the safety significance of this event is considered very low.
F. CORRECTIVE ACTION
The immediate corrective actions was the installation of an appropriately EO qualified splice suitable for use inside containment. Also there was additional training conducted subsequent to the installation of the splice for design engineering to strengthen understanding of design inputs. A new expectation to have a corporate environmental qualification specialist review design packages when working with EO component replacements was also implemented.
G. ADDITIONAL INFORMATION
- 1) Failed Components:
The component did not fail. Its operability could not be supported for cycle 27 due to the untested configuration for EO purposes.
- 2) Previous Similar Events:
None
- 3) Other system affected:
No systems other than those mentioned in this report were affected by this event.
- 4) Commitment Information: This report does not create any licensing commitments
