| Event Description | The licensee provided the following information via facsimile:
Pursuant to Title 10, Code of Federal Regulations, Part 21, reporting requirements, Sulzer Pumps (US), Inc. is reporting a deviation from technical requirements for components to be used in nuclear safety related applications. Sulzer Pumps (US) Inc. owns and operates a centrifugal pump repair and manufacturing facility at 4126 Caine Lane, Chattanooga, TN 37421. On May 7, 2006 during manufacturing we became aware of what appeared to be weld repairs to two pump bowl castings to be used in a replacement Essential Service Water Pump we are manufacturing for the J. M. Farley Nuclear Power plant. The supplier for these castings is Stainless Steel Foundry and Engineering, 5110 North 35 th St., Milwaukee, WI 53209, (414) 462-7400. The Sulzer Pumps (US) procurement documents to the foundry required weld repairs to the castings be preceded by notification to us, submission for approval of both the proposed weld procedure (WPS) to be used, and the weld procedure qualification record (PQR). Weld maps are also required by our procurement documents. In the case of our PO # 08407520, we received material certifications from Stainless Foundry and Engineering which certified no welding was performed to the castings. During our inspection processes we discovered what appeared to be weld repairs not traceable to us or to the above named Stainless Foundry. Subsequent investigation by Sulzer Pumps (US) and foundry representatives concluded that undocumented and unapproved weld repairs were performed by the foundry. Additional research by Sulzer Pumps (US) identified other castings supplied by Stainless Foundry and Engineering which were used in orders previously processed and shipped by Sulzer. The documentation supplied by Stainless Foundry stated none of these castings had required weld repair by the foundry. Our records indicate the castings that have been supplied are impellers. However, based on the aforementioned discoveries they too may contain undocumented weld repairs. We have reviewed and identified the nuclear power plants where pumps using these castings were shipped which are listed below. They are: Indian Point, Cust PO# 4500533843, our job number 04JC1423; and E.I. Hatch, Cust PO# 6057240, our job number 04JC1505. All other castings from Stainless Foundry and Engineering that we received have been placed on hold and will be returned to the foundry. We are in the process of evaluating our options to obtain replacement castings. |
