INTERIM REPORT SIGNIFICANT CONSTRUCTION DEFICIENCY No. 67

" FAILURE OF A500 GRADE "B" TUBE STEEL TO MEET CHEMICAL / PHYSICAL PROPERTIES" INTRODUCTION This report is submitted pursuant to 10CFR50.55(e). It describes deficiencies in the tube steel used in the fabrication of hanger supports in the chilled water, component cooling and blowdown systems. This condition is considered reportable under the requirements of 10CFR50.55(e).

To the best of our knowledge, this problem has not been reported to the Nuclear Regulatory Commission pursuant to 10CFR21.

DESCRIPTION In May,1982 Ebasco received one (1) piece of 40' x 4" x 4" x b" square structural tubing ASTM A500 76 Grade "B", heat number 803L75350 (Mfg. Regal Tube) from Pressure Vessel Nuclear Steels, Inc. along with certification papers which were acceptable to ASTM A-500 specifications. On October 20, 1982 Ebasco received a telex from Pressure Vessel Nuclear Steels, Inc. stating: "It has been determined that this one piece of ASTM A-500 tube steel has low elongation problem". 2rior to October 20, 1982 Ebasco had furnished this tubing to Tompkins-Beckwith (Mech.

Contractor) for use as hanger supports. Tompkins-Beckwith, since then has used this tubing to fabricate seven (7) hangers which are installed in Seismic I Installations. Presently, all tubing has been identified and placed on hold.

SAFETY IMPLICATIONS Based on the information presently available, we are unable to make a determination relative to the significance of this item. Although we have been informed by the v9ndor that the material has failed elongation tests, no actual physical property data has been submitted to engineering.

Presently we are waiting on physical property data that is to be sent by the _

vendor no later than Monday, November 22, 1982. Upon receipt of this data, calculations will be performed to establish the acceptability of this material for use in seismic Class I pipe support installations. These calculations will be done based on the actual loads on a case-by-case basis.

CORRECTIVE ACTION NCR-W3-4827 has been initiated to track and document corrective action as dispositioned.

Further information will be submitted to the NRC no later than December 19, 1982.
