Technical Report ·
DOI:https://doi.org/10.2172/5496989· OSTI ID:5496989
Documentation is provided in this report for the closeout of IE Bulletin 86-02 regarding static O'' ring differential pressure switches Series 102 or 103 supplied by SOR, Incorporated, as electrical equipment important to safety. Closeout is based on the implementation and verification of either one or six actions required by the bulletin for holders of an operating license or a construction permit for a nuclear power plant. All six actions are required when the facility is equipped with the switches of concern in systems subject to limiting conditions for operations in technical specifications. Evaluation of utility responses and NRC/Region inspection reports in accordance with two criteria indicates that the bulletin is closed for 116 (97%) of the 119 nuclear power facilities to which it was issued for action. Followup items are proposed for the three (3) facilities with open status, for the use of NRC regional inspectors in ensuring successful completion of required and corrective actions. A conclusion based on the utility responses is presented.
