Response to Request for Additional Information

ATTACHMENT RESPONSE TO NRC REQUEST FOR ADDITIONAL INFORMATION RAI #1: Decommissioning Expenses Per 10 CFR 50.75(e)(2),

The NRC reserves the right to take the following steps in order to ensure a licensee's adequate accumulation of decommissioning funds: review, as needed, the rate of accumulation of decommissioning funds.

Per 10 CFR 50.75(g),

Each license shall keep records of information important to the safe and effective decommissioning of the facility in an identified location until the license is terminated by the Commission. If records of relevant information are kept for other purposes, reference to these records and their locations may be used. Information the Commission considers important to decommissioning consists of-

[..1 (3) Records of the cost estimate performed for the decommissioning funding plant or of the amount certified for decommissioning, and records of the funding method used for assuring funds if either a funding plan or certification is used.

Please provide the amount spent on decommissioning prior to September 1, 2010, in a schedule showing the expenses each year since the permanent cessation of operations. Provide the amount withdrawn from the decommissioning trust fund for expenses related to decommissioning planning prior to the permanent cessation of operation Response to RAI #1 The annual amounts spent on decommissioning since the permanent cessation of operations in January 1998 (excluding decommissioning planning expenses), and eligible for reimbursement from the decommissioning trust funds, are shown in Table 1.

Table 1 covers all expenses related to Zion Nuclear Power Station (ZNPS) decommissioning (excluding decommissioning planning expenses), incurred from February 13, 1998 through August 31, 2010. Note that all decommissioning related expenses (excluding decommissioning planning expenses) incurred at ZNPS during 1998 and 1999 were paid through operating funds, and no withdrawals were made from the decommissioning trust funds for reimbursement of these expenses.

The amounts withdrawn from the decommissioning trust funds related to decommissioning planning activities that occurred prior to and after the permanent cessation of operations are given in Table 2. Note that the expenses in Table 2 for calendar year 1998 were incurred after permanent cessation of operations, but were related to decommissioning planning, so the expenses are included here instead of in Table 1.
