UNITED STATES NUCLEAR REGULATORY COMMISSION OFFICE OF NUCLEAR REACTOR REGULATION WASHINGTON, D.C. 20555 December 6, 1989 Information Notice No. 89-59, SUPPLEMENT 1: SUPPLIERS OF POTENTIALLY MISREPRESENTED FASTENERS Addressees: All holders of operating licenses or construction permits for nuclear power reactors. Purpose: This information notice is intended to provide supplementary information to that provided in Information Notice 89-59 which identified the Service Supply Company as providing fasteners suspected of being misrepresented. The NRC has been informed by the source of this information that it cannot be determined that Service Supply Company did in fact supply suspect fasteners. As a result of Information Notice 89-59, recipients may have removed Service Supply Company from their approved vendors list. It is expected that recipients will review the information for applicability to their facilities and consider actions, as appropriate, to avoid similar problems. However, suggestions contained in this information notice do not constitute NRC requirements; therefore, no specific action or written response is required. Background: On August 16, 1989, the NRC issued Information Notice 89-59 to all holders of operating licenses or construction permits for nuclear power reactors. This notice supplied names and addresses, if known, of companies suspected of supplying fasteners to the industry that may have been misrepresented, that is, marked as having a material content and composition different from the actual content. The information notice was issued to provide to the nuclear industry the results of NRC's review of fastener test data that the licensees provided in response to NRC Bulletin 87-02, "Fastener Testing To Determine Conformance With Applicable Material Specifications." The vendor names and addresses were taken from this licensee supplied data. However, in a letter to the NRC dated November 13, 1989, the Omaha Public Power District (OPPD) clarified that its January 19, 1988, submittal responding to NRC Bulletin 87-02 did not support the conclusion that the Service Supply Company was a supplier of fasteners suspected of being misrepresented. OPPD stated that, although Service Supply Company is its primary supplier of nonsafety-related 8911300021 . IN 89-59, Supplement 1 December 6, 1989 Page 2 of 2 fasteners, other suppliers were also used. OPPD did not segregate the nonsafety-related fasteners supplied by the Service Supply Company from those provided by other vendors and therefore cannot positively trace the fasteners to any supplier. Discussion: Over the past several years, various industries, associations, and Federal agencies have identified the presence of misrepresented fasteners among fasteners they have procured. Because of the potential safety significance of this issue, the NRC, in cooperation with other Federal agencies, has been actively trying to identify suspected suppliers or manufacturers of misrepresented fasteners. Because of the potential adverse affect of releasing such information, it is imperative that the information be correct. In instances such as this, the NRC relies on the licensees to provide correct information. This information notice requires no specific action or written response.
