Information Notice No. 88-19:  QUESTIONABLE CERTIFICATION OF 
                                   CLASS 1E COMPONENTS


All holders of operating licenses or construction permits for nuclear power 


This information notice is being provided to alert addressees to a possible 
problem with the certification of Class 1E components furnished by Planned 
Maintenance Systems (PMS) of Mt. Vernon, Illinois.  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.  

Description of Circumstances:

On April 1, 1988, Wolf Creek Nuclear Operating Corporation (WCNOC) submitted a 
written 10 CFR Part 21 Notification to NRC Region IV concerning 60 Class 1E 
fuses that had been procured from PMS.  One of the requirements of the 
purchase order (PO) issued to PMS was that the PO items were to be supplied in 
accordance with the requirements of a specific fuse qualification 
specification for Class 1E equipment.  This specification contained detailed 
requirements including materials, environmental qualification, seismic 
qualification, and inspection/ test requirements.  The PMS Certificate of 
Compliance supplied with the order certified that all of the procurement 
document requirements had been met and no deviations from the requirements had 
been identified. 

The fuses were placed on hold by WCNOC because a required Quality Department 
surveillance had not been performed.  A subsequent WCNOC surveillance revealed 
that the records in PMS's possession did not support the statement on the PMS 
Certificate of Compliance that all PO requirements had been met.  
Qualification specification requirements were not covered by PMS quality 
assurance records with respect to information on environmental qualification, 
radiation levels, and seismic qualification.  In addition, it could not be 
established that a required continuity/resistance check of each fuse had been 
performed before the fuses were shipped.

                                                            April 26, 1988

The WCNOC 10 CFR Part 21 notification has brought into question the validity 
of the Certificate of Compliance issued by PMS for Class 1E fuses that they 
supplied.  Accordingly, licensees may wish to review Class 1E component pro-
curements from this vendor to ensure that appropriate bases exist for the use 
of the components.

No specific action or written response is required by this information notice.
