NUCLEAR PLANT NO. 2, OPERATING LICENSE NPF-21 RESOLUTION OF ANTICIPATED TRANSIENTS WITHOUT SCRAM (ATWS) FOR WNP-2
 
==Reference:==
Letter, G02-89-231, GC Sorensen (SS) to NRC, "Schedule for Resolu-tion of Anticipated Transients Without Scram'ATWS) for WNP-2",
dated December 28, 1989.
In the referenced    letter,  the Supply System indicated that          we  expected to be able to confirm that the          ATWS    equipment      for  WNP-2    satisfies the environmental qualification requirements of the ATWS rule (10 CFR 50.62) by June 29,                  1990. The purpose of this letter is to advise the NRC that we have successfully                    completed this action.
The  ATWS equipment      has been determined to be qualified to normal design environmental conditions followed by an ATWS accident environment by the use of either:
a)    Materials analysis of ageable              components    including test reports      when available; b)      Existing qualification to other              accident    profiles    (LOCA,  HELB)  that encompass    the ATWS profile; or 9007100170 900629
,PDR    ADCCK 05000397 P                    PDC
 
Page Two SCHEDULE FOR RESOLUTION OF ANTICIPATED TRANSIENTS WITHOUT SCRAM (ATWS) FOR WNP-2 c)      Location in    a mild environment that is not affected by the    ATWS accident environment.
All equipment identified with      an ATWS safety function has been reviewed and found to  be  acceptable from    an  environmental  qualification standpoint.
