REVISION 3 08/29/84 SSER Task: Allegation A-126, A-291 Reference No.: 4-84-A-06/21, 172 Cha racterization: It is alleged that Tompkins-Beckwith (T-B) did not maintain material traceability on the supplemental steel used with pipe hangers and supports. The supplemental steel refers to additional steel used to install pre-fabricated pipe hanger,s and supports.

Assessment of Allegation: Bergen-Patterson (B-P) furnished pre-fabricated ,

piping supports and hangers. E9ASCO furnished the supplemental structural steel for use by T-3 during installation of the piping hangers and supports.

The supports and supplemental material were designed to Seismic Category I requirements. 10 CFR 50, Appendix B quality assurance requirements apply.

Section VIII of this specification allows identification of an item to be maintained by records traceable to the item. As a result, Certificates of Compliance furnished by the suppliers verified that the material furnished was properly certified in accordance with the applicable ASTM Specifications.

The EBASCO Material Inspection Receiving Report (MIRR) was used to verify that the correct material was received. A Requisition on Warehouse (R0W) was used by T-B to obtain releasf of the material from EBASCO.

The initial T-B program was established to provide traceability of the paint to be used on the su)plemental steel. A material control number was steel stenciled on eac1 item listed on the R0W. If the material was cut into smaller pieces, the number was to be transferred accordingly.

Af ter number stamping, the material was painted by a subcontractor.

Different colored paint was used with yellow signifying non-safety non-permanent material. The other colors used designated safety related material. ,

In 1978, T-B agreed to a contract change with EBASCO to extend the paint material traceability system to also include steel traceability. Because the change came after the original program had been in operation, a number of implementation problems occurred and providing full steel traceability proved difficult.

In lat91983, the contract between EBASCO and T-B was changed to reflect a deedsion by EBASCO to abandon attempts to provide supplemental structural steel traceability using material control numbers. The supplemental structural steel certification program continued to be in effect as it had been throughout the project.

'A-126 The alleger based his concern on his knowledge of the material traceability: system that was in effect June 1978 to 1984. The system described in the allegation is not representative of the original or final programs. .The change back to th.e. original material control system in early 1984 resolves the concern of the alleger. The NRC staff concludes that the support material traceability meets the requirements

. .of 10 CFR 50, Appendix B.

The NRC staff discussed these findings with the alleger on May 3, 1984.

He agreed and expressed satisfaction with the explanation and resolutions of this issue. This allegation has no safety significance nor generic implications. ,

IPotentialViolations: NoneI 1, d Actions Required: None.
