Washington, DC 20555 - 0001 DOCKET 50-155 - LICENSE DPR BIG ROCK POINT PLANT - APPLICATION FOR AMENDMENT OF LICENSE PURSUANT TO 10 CFR 50.90 - SECURITY PLAN In accordance with 10 CFR 50.54(p)(1), an application for amendment to the Big Rock Point License pursuant to 10 CFR 50.90 is enclosed. Since the reactor has been permanently defueled and will no longer be operated, the Security Plan is being revised to reduce the scope of the plan to correspond to the condition of the facility. The Big Rock Point Staff has concluded that the changes required may constitute a decrease in the effectiveness of the current plan, therefore prior approval of the Commission is required.

Consumers Energy Company notified the Nuclear Regulatory Commission (NRC) by letters dated June 18, and June 26,1997, ofits intentions to permanently cease operations of the Big Rock Point Nuclear Plant by August 30,1997; and as certified, the plant was shutdown on August 29,1997. On September 22,1997, a letter pursuant to 10 CFR 50.82(a)(1)(ii) was forwarded to the Commission, certifying that the fuel has been removed from the reactor vessel and placed in the spent fuel pool for

]

storage. In accordance with 10 CFR 50.82(a)(2), upon docketing of the certifications for permanent j

cessation of operations and permanent removal of fuel from the reactor vessel, the 10 CFR part 50 license no longer authorizes operation of the reactor or emplacement or retention of fuel into the reactor vessel. In this condition, design basis accidents associated with the operation of a nuclear plant are no longer credible for the Big Rock Point facility, therefore the appropriate Security Plan j

for the defueled condition needs to be established. However, since the remaining source of public risk

{

is associated with the spent fuel pool, complete spent fuel pool drainage is an accident of potential l

concern. Certain combinations of spent fuel storage configurations and decay times, could cause freshly discharged fuel assemblies to self heat to a temperature where the self sustained oxidation of j

the zircaloy fuel cladding could cause cladding failure. Therefore, Consumers Energy Company will

fonvard an analysis to the NRC that determines the point in time after permanent shutdown when the l

spent fuel decay heat is low enough such that no zircaloy oxidation takes place, and the spent _ fuel '

claddmg remains intact upon extended exposure to air. The proposed Defueled Security Plan will only be implemented after that point in time.-

A discussion of the proposed amendment and a summary of the Significant Hazards Determination

are provided in Attachment 1. Attachment 2 provides the justi6 cation for changes to the plan, provides the proposed Security Plan, and Attachment 4 provides the current plan as a reference.

Consumers Energy Company requests that Attachments 2 through 4 to this letter be withheld from public di losure in accordance with 10 CFR 73.21 m
