Information Notice No. 89-59, SUPPLEMENT 2:  SUPPLIERS OF POTENTIALLY 
                                                 MISREPRESENTED FASTENERS


Addressees:

All holders of operating licenses or construction permits for nuclear power 
reactors

Purpose:

This information notice supplement is intended to inform addressees that the 
NRC has been notified by its original source, the Northern States Power 
Company (NSP), that it cannot be determined that Phoell Manufacturing did, 
in fact, supply suspect fasteners.  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:

NRC Information Notice (IN) 89-59, "Suppliers of Potentially Misrepresented 
Fasteners," was issued August 16, 1989, to provide addressees with the names 
and addresses, if known, of companies suspected of supplying fasteners to 
the nuclear industry that may have been misrepresented, that is, marked as 
having a material content and composition different from the actual content.  
The names and addresses were taken from the data that the licensees provided 
in response to NRC Bulletin 87-02, "Fastener Testing to Determine 
Conformance With Applicable Material Specifications."

Phoell Manufacturing was named in IN 89-59 as a result of test data that NSP
supplied in response to NRC Bulletin 87-02.  However, in a letter to the NRC 
dated January 30, 1990, NSP indicated that it is possible that Phoell 
Manufacturing did not supply the non-safety-related fastener, which showed a 
lower-than-specified carbon content.  NSP stated that their maintenance 
group consistently bought bolts of that size from Phoell Manufacturing.  
However, because it was a non-safety-related bolt, the bolt in question 
could have been left over from construction projects that had received 
materials from other suppliers.

Discussion:

Over the past several years, various industries, associations, and Federal 
agencies have identified misrepresented fasteners among fasteners they have 
procured.  Because of the potential safety significance of using 
misrepresented fasteners, 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 
effect of releasing incorrect information about suppliers or manufacturers 
of components, 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.  If
