* Supplemental Information ,,

3b/28 - The spent fuel pit pump does not have a direct LOCA-mitigatingfunction. However, in the event of an accident, degradation ofspent fuel pit pump performance could result in a temperatureproblem ith the spent fuel pool that, because of personnelrestrictions created by the accident, could not be corrected.For the interim, the "in-site" equipment is acceptable sinceno spent fuel has been stored. However, to correct thissituation, TVA will, by the first refueling outage, provideanalyses which verify that the equipment is qualified, or repair,

and/or replace, as required.
