Dear Mr. Keppler:
References (a) through (c) provided information concerning a deficiency reportable pursuant to 10 CFR 50.55(e) regarding the removal of nameplates from ASME large bore spool pieces at our Braidwood Station.
The purpose of this letter is to provide an updated status of the corrective actions being taken to resolve this issue.
This letter is considered to be a final Report.
Corrective Actions Being Taken As previously reported, Commonwealth Edison Company NCR No.
639 and Phillips, Getschow Company NCR No. 1783 have been generated to document this item and track its resolution.
The installed large bore piping spools that do not have ASME NPT nameplates continue to be identified as part of the Material Traceability Verification (MTV) Program.
Phillips Getschow Company is currently in the process of researching and verifying those spool pieces in accordance with their procedure, PGCP-51.
This research and verification will accomplish the following tasks:
1.
Determine the total population of installed spool pieces that do not have nameplates attached.
Verify the identity of installed spool pieces using ]?,
2.
manufacturer's documentation.

, -3.-
Field check installed spool pieces without nameplates toglocate. nameplate removal areas.
4..
Perform NDE required by ASME Section III on nameplate removal areas.
5.

.to insure that minimum wall thickness is maintained.
6.
Any required repair to the nameplate removal area will be performed per established procedures.

With the concurrence of Commonwealth Edison Co. and the Authorized Nuclear Inspector, replacement identification plates will be attached to the installed spool pieces.
8.
Resolve on.a case.by case basis,~those spool pieces for which a nameplate or nameplate' removal area can not be located.
As previously identified, it is expected that approximately 600 spool' pieces will be involved in this program.
At present, there are 509 spool pieces-in this' program.
A list will be developed by Phillip's,' Getschow Company of isometric-. drawings outside the scope of MTV.- Spool pieces.not within the scope of MTV that was not1 subject to installation procedures to properly control removal of NPT nameplates will have a_
separate-visual exam to verify nameplate attachment ~.
Current estimates indicate-that1this program will be complete in September, 1985.
Final'results'will be available for NRC review at that time.
In the interim, the implementation-activities -and results to date will be' available for NRC review.
Please address.any questions that you or your staff may
