DOCKET NOS. 50 445 AND 50 446 RESPONSE TO GENERIC LETTER 90 04: RE0 VEST FOR l INFORMATION ON THE STATUS Of LICENSEE IMPLEHENTATION Of GENERIC SAFETY ISSUES (GSI) RESOLVED WITH '

IMPOSITION Of REQUIREMENTS OR CORRECTIVE ACTIONS Gentlemen:

Enclosed is the CPSES response to Generic letter 90 04. The response includes l the table entitled " Status of Licensee Implementation of Generic Status. Issues Resolved with imposition of Requirements or Corrective Actions" (Enclosure 1) i which has been marked up to indicate the CPSES status for each of the GSI's as requested, in addition. Enclosure 2.provides a listing of docketed correspondence related to the GSis and in some cases a brief explanation of the outstanding work.

i for those GSI's statused as incomplete in Enclosure 1, the dates correspond to CPSES current scheduled milestones (i.e.. GS! 99 Prior to end of first refuel outage for Unit 1/ Unit 2 fuel load, GSI A prior to initial. full power o"eration for Unit 2). The date indicated for colnpletion of Unit 2 activities, except that for GSI A 35, corresponds to CPSES current scheduled Unit 2 fuel load milestone.

Activities necessary to resolve each GSI were discussed in the CPSES correspondence related to each GSI and were discussed and accepted in NUREG 0797 Supplement No. 24. 10 Electric intends to implement for Unit 2 the same activities that were performed for Unit 1 (Enclosure 2). Host of these Unit 2 activities have not been completed because Unit 2 is still in the early stages of the re initiated design and construction activities.
