NUCLEAR REGULATORY COt1RIISSION ALL NUCLEAR POWER REACTORS PECEIPT AND DENIAL OF PETITION FOR DIRECTOR'S DECISION UNDER 10 CFR 5 2.206 Notice is hereby given that by Petition dated November 25, 1991, Richard P. Grill requested the Executive Director for Operations to institute a proceeding, pursuant to 10 CFR 2.202, "to suspend the operating license of any nuclear power plant licensed by the Commission whose license is not
\\
supported by:
a) a thorough analysis of the effects of lightning induced and other electrical transients on nuclear safety related electrical or electronic systems; b) a determination of potential accident scenarios and their consequences resulting from electrical and electronic system failures; I
c) the consequences to both the plant and to public health and safety from such accidents; d) the specific design features incorporated to prevent system failures from electrical transients; e) the technical specifications and maintenance features to assure safe operability of these design features and the systems they protect and f) a thorough licensing review of the above by competent HRC staff."
The Petitioner asserts as grounds for this request that the safety-related control and monitoring systems in nuclear power plants are complex and sophisticated with designs based on transistors and solid state integrated logic systems which can be disrupted by "small fluctuations of current",
that the NRC has not critically evaluated the effect of electrical transients induced by lightning, switching surges or other sources on the electrical and 9201160173 920110 PDR ADOCK 05000275 P
L, electronic monitoring and control designs of any "single U. S. nuclear power plant",
and recent lightning related and electrical surge incidents have compromised both NRC and DOE facilities.
The Office of Nuclear Reactor Regulation (NRR) has evaluated the Petition and concluded that it does not provide any basis for immediate suspension of the operating licenses of any NRC-licensed nuclear power plants.
In view of this lack of a sufficient basis for immediate action and since the same issues are being treated in a rulemaking requested by the Petitioner on August 16, 1991, which has been docketed by the Commission fnotice of that action was published on December 23, 1991 in the FEDERAL REGISTER (56 FR 66377)], the Petition has been denied by letter to the Petitioner, dated January 10, 1992.
Dated at Rockvi lie, Maryland this 10th day of january 1992.
