1.0 Introduction i
Ccrtain bolts, nuts, and studs have been furnished to the Limerick Jobsite for ASME service which did not comply with NA-3700 of ASME Section III, Winter, 1976.
In compliance with 10CFR 50 55(e), this Final Report is issued to describe the deficiency, analyze the safety implications, and describe the corrective action taken.
This deficiency was first reported to the USERC, Region I, via telecon on August 26, 1980. A written interim report was submitted on September 25,1980 which co=mitted to this report by December 30, 1980.
2.0 Descriotion of Problem The Limerick Project has been supplied ASME Section III bolts, nuts and studs by REC Corporation, New Rochelle, New York. These bolting materials were procured by REC from material manufacturers that do not have Quality assurance programs that have been approved by Bechtel. Such approval is contingent upon either the material =anufacturer holding a current ASME Quality System Certificate (Materials) or upcn a satisfactory survey of the manufacturer by Bechtel.
Our interim report of September 25, 1980 indicated that appror h tely 25,000 items were involved with 10% installed.
Our final inventory indicates that 16,631 items are involved of which h92 were issued for installation (all for use at flanged joints). These items, all supplied by REC Corporation, came from the following material manufacturers or suppliers:
l Allied International Shigayama and Co., Ltd.
Kurt Orban Co., Inc.
Wycoff Steel Republic Steel (Cleveland Plant)
Colt Industries (Crucible Divi.sjer)
B & G Manufacturing Co., which was listed on our interim report, supplied material for use only in balance of plant systems. B and G material is acceptable for its intended use. Kinki Marusi Nut Kyogyo Kumia, which was listed separately on our interim report, supplied material to Shigayama and Co. Ltd.
30 Analysis of Safety Imolications Because of the large number of bolts involved and the large number of applications where they were used or could have been used it is not feasible to hypothesize and analyze individual applications regarding safety implications.
It may be stated in general that the confidence level in this bolting is lessened due to a lack of proper review of the QA program under which they were manufactured.
Had this condition gone u: detected safety could have been compromised in the event of bolting failure.

h.0 Co nective Action Taken The eight Non-Cenfor=ance Reports mentioned in our interim report of Septecber 25, 1980 were dispositioned as follows:
The NCR dealing with 3 and G was dispositioned to use 3 and G materials in balance of plant applications as they meet specification requirements for these applications. Tne other seven NCR's were dispositioned to return all non-conforming ite=s to REC.
All flanges that have been made up and accepted by QC to date will be reviewed for heat numbers relating to the above unacceptable material
=anufacturers supplied by REC. All unacceptable bolting material identified will be replaced.
Further, a list of unacceptable bolting heat nu=bers will be provided to QC with the requirement that unacceptable bolting be rejected where they occur in ASME joints which have been made up but have not yet received QC acceptance. This procedure will insure that all unacceptable bolting is replaced with =aterial approved for use in ASME applications.
In order to preclude recurrence of this or related problems Limerick Field personnel, who are responsible for procurement, have been reindoctrinated regarding candatory requirements for materials which are to be used in ASME applications.
3.0 Conclusions The corrective actions described above will correct and eli=inate the problem related to ASME bolts, nuts and studs obtained from unapproved Sources.
