!! C REPLACEMENT OF DRYNELL' PENETRATION BELLOHS L'

c l(, .  !

Gentlemen: l w - OnL October .4,1989, ' a- conference call' was held among representatives ]

from Georgia'. Power Company (GPC), 'Bechtel Power. NRR, and Region .II to '

l l' , discuss ' activities surrounding the replacement of Unit Two drywell penetration bellows . assembly 2T23-X9A. As discuss &d, replacement of-the i bellows' was necessary following --failure of its' local leak rate '. test ,

7 since the: configuration of the-bellows assembly made repair of the inner 7, seal impossible. At the conclusion of the conference call, participating .

NRC-- staff members ' concurred with the use of Pathway Corp. as the o replacement bellows vendor.

The purpose 'of this letter is to document NRC agreement with the GPC justification for: the use of Pathway Corp. as the replacement bellows vendor. '

1 As presented in the conference call, GPC contacted 13 utilities and ? .[

suppliers in an effort to obtain a replacement be170ws with an ASME  :

Section III' N-Stamp. Due to the fact that the bellows assemblies at ,

Plant. Hatch were custom made, it was determined that none of the  :

companies contacted had an "off the shelf" assembly suitable for our I application. Generic Letter 89-09 permits a licensee to use a non

', ' N-stamped ~ vendor as long as it has been determined that an equivalent ,

, ASME Section III stamped replacement is not available. In the course of our investigation it was identified that only one vendor, Metal Bellows Corp., currently holds an N-Stamp. However, as discussed during the October 4th conference call, GPC believes that, in this situation, it is more prudent to obtain a replacement component from Pathway Corp. for the

[m following reasons:

based on the information provided by GPC, the use of Pathway Corp. as the ,
