REVIS0N 0 06/27/84 SSER Task: Allegation A-126, A-291 Reference No.: 4-84-A-06: 21, 172 Characterization: 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 means additional steel used to install pre-fabricated pipe hangers and supports.

Assessment of Allegation: Bergen-Patterson (B-P) furnished piping supports and hangers. EBASCO furnished supplemental structural steel for use by T-B during installation of the piping hangers and supports.

The EBASCO specifications and 10 CFR 50, Appendix B requirements specify that only properly certified material in accordance with ASTM specifications be used for supports and hangers. B-P and the structural steel suppliers to EBASCO provided Certificates of Compliance (C of C) with each shipment. The C of C stated that the material furnished met ASTM specifications.

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

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

After 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 i change came after the original program had been in operation, a number of implementation problems occurred and providing full steel traceability proved difficult.

In late 1983, the contract between E8ASCO and T-B was changed to reflect a decision 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.

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 the original material control system in early 1984 resolves the concern of the alleger. Our evaluation concludes that the support material traceability neet the requirements of 10 CFR 50, Appendix B.

We have discussed our findings with the alleger on May 3, 1984 He agreed and expressed satisfaction with our explanation and resolutions. This allegation has no safety significance.

Potential Violations: None.

Actions Recuired: None.
