Status of Commitments for the Feed and Bleed Modification Gentlemen:
As recently discussed with Mr. Jon B. Hopkins (NRC Senior Project Manager), Toledo Edison submitted a letter (Serial Number 1836) dated September 18, 1990 which summarized the numerous modifications made for enhancing the feed and bleed cooling capability for the primary syatem of the Davis-Besse Nuclear Power Station (DBNPS).
Although feed and bleed cooling would only be required in a be ond-design basis. event, Toledo Edison committed to enhance the electrical components which support the feed and bleed cooling capability, to be functional following a seismic event.
In this letter, Tcledo Edison stated that the work had been completed to enhance the necessary electrical components for a seismic event.
During the modification closeout process by Toledo Edison, two relay 9
cabinets were identified as missing seismic supports and fou. conduits needed rework and tightening to meet Seismic Qualification Utility Group (SOUG) or seismic class I criteria.
Vork had also not been completed to de-terminate and spare a cable's ground shield.
A nonconformance report was written to initiate corrective action to 3
correct these discrepant items' capability for feed and bleed. As part of the corrective actions for the nonconformance report, a reviev was performed to identify if additional work vas still outstanding and required completion.
Based upon this review, no further outstanding work was found to need completion.
