.N Gentlemen:
By now you have had the opportunity to review the 84 work sheets selected by UCS from the licensee's January 30, 1981 submittalito NRC on the ouvironment91 qualification of equipment in TM7-1.
Pursuant to the agreement of the parties to find an alternative to questioning Mssrs. Rosztoczy and LaGrange to establish the basis for admicsibility of these worksheets, we are hereby responding to the requests of Mssrs. Baxter and Cutchin.
The-following pages of UCS 39 are duplicated in Staff Exhibit 16:
4, 27-37, 40, 41, 46-50, 54-73, 80 and 82-84.
In addition to some of these, pages 13 and 39 were used during cross-examination.
Beyond this, Mr. Baxter asked us to identify the reasons why we had selected these particular worksheets (eg., Tr. 22069).
For all of the other worksheets, that information is as follows:
The following pages of UCS Ex.39 contain information on components identified by the Licensee in the master list for cold shutdown (which is included in UCS Ex. 38) 503 and indicate deficiencies in qualification:
9 Pages 8-12',
26, 42-45, and 74-79.

Pages 1, 2, and 3 of UCS Ex. 39 pertain to equip.ent located inside containment (and thus exposed to the SBLOCA environment) used to isolate feedwater in the event of a steam line rupture.
Their failure in the LOCA environment
'could lead to isolation of feedwater during a LOCA.
Pages 5, 6,
7, 22, 24, and 25 contain information showing that equipment which may be used to cope with i
SBLOCA is not qualified even for the ambient conditions at their locations.
t Pages 14-26 illustrate the extent of qualification of EFW/MFW equipment reflecting on the adequacy of the Staff's feedwater reliability assessment and extent of compliance with lessons learned requirements re :
feedwater transients and EFW reliability.
This responds to the questions you posed.
I there-fore propose that the material marked as UCS Exhibit 39 be stipulated into evidence in order to obviate the need to do more questioning of the witnesses.
Please let me kl.ow if you are agreeable so we can notify the Board.
~
very truly yours, le!!'
