Dear Mr. Keppler:
On July 24, 1984, the Commonwealth Edison Company notified your office of 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.
This deficiency was assigned Number 84-12 for your tracking purposes.
This letter fulfills the thirty day reporting requirements of 10 CFR 50.55(e) regarding this matter, and is considered to be an interim report..
I DESCRIPTION OF DEFICIENCY ASME NPT symbol nameplates were removed from piping subassemblies without proper controls and documentation.
Nondestructive examinations required by ASME Section III of the nameplate removal areas were not subsequently performed.
ANALYSIS OF SAFETY IMPLICATIONS The piping systems involved are ASME Section III and are Safety Category I.
Lack of required nondestructive surface examinations and wall thickness measurements could potentially result in allowing conditions to exist that do not meet the design requirements.
This could potentially allow ~ piping defects to exist which may impact on the safety function of the systems involved.
CORRECTIVE ACTION TAKEN Commonwealth Edison Company NCR No. 639 and Phillips Getschow Company NCR No. 1783 have been generated to document this item and track its resolution.
Phillips Getschow Company will initiate a program to determine the total number of nameplates 8409070426 840824 PDR ADOCM 05000456 AUG E 7 0g S
