In accordance with
10CFR52.99(c)(2), V.C. Summer Units 2 and 3 Construction is making this notification to NRC for determining that Inspection, Test, Analysis, and Acceptance Criteria (
ITAAC) 2.6.01.02.ii (Seismic Qualification of Reactor Coolant Pump Switchgear) for both units requires additional actions to restore its completed status. The Closure Notification for this
ITAAC (NRC Index No. 580) was originally submitted on February 29, 2016 (reference
ML16060A344 and
ML16060A345).
On November 2, 2016, it was determined that modifications to the RCP switchgear cabinet design were required to ensure compliance with the applicable portions of IEEE 384, Standard Criteria for Independence of Class 1E Equipment and Circuits. The modification involved an engineering change which adds different equipment to the RCP Switchgear cabinet which function to trip the RCP. The new components were not previously seismically qualified for use in the RCP switchgear cabinet assembly. The additional components have now undergone seismic qualification testing for use in the RCP switchgear. The Equipment Qualification Data Package and Equipment Qualification Summary Report for the RCP switchgear will be revised based on the results of the testing to confirm the switchgear withstands seismic design basis loads. The revised testing report has been completed on November 8 2016.
The licensee notified the NRC Resident Inspector.
