Response to Request for Additional Information cc: Regional Administrator, U.S. NRC Region Ill U.S. NRC Senior Resident Inspector, Braidwood Station U.S. NRC Senior Resident Inspector, Byron Station 1 ATTACHMENT RESPONSE TO NRC REQUEST FOR ADDITIONAL INFORMATION Braidwood and Byron Question 1 In accordance with Title 10 of the Code of Federal Regulations (10 CFR), Section 50.75(b)(2):
The NRC reserves the right to take the following steps in order to ensure a licensee's adequate accumulation of decommissioning funds; and, either independently or in cooperation with the FERC and the licensee's State PUC, take additional actions as appropriate on a case-by-case basis, including modification of a licensee's schedule for the accumulation of decommissioning funds.
Provide balances for the respective decommissioning trust funds for Braidwood Unit 1 and Braidwood Unit 2 as of July 31, 2009, August 31, 2009, September 30, 2009 and October 31, 2009.
Provide balances for the respective decommissioning trust funds for Byron Unit 1 and Byron Unit 2 as of July 31, 2009, August 31, 2009, September 30, 2009 and October 31, 2009.
Response to Question 1
The decommissioning trust fund balances for Braidwood Station, Units 1 and 2 and Byron Station, Units 1 and 2 are provided below for the dates requested. Additional information is also provided for November 30, 2009, and December 31, 2009, to show the performance of the trust funds from the time of the submittal of EGC's decommissioning funding assurance plan through the end of 2009, the date EGC will use to calculate any required additional decommissioning funding assurance as described in the Reference.
Date Braidwood Unit 1 Braidwood Unit 2 Byron Unit 1 Byron Unit 2 July 31, 2009 $187.5M $207.1M $210.1M $203.6M August 31, 2009 $193.5M $213.4M $216.4M $209.9M September 30, 2009 $199.3M $219.5M $222.6M $216.0M October 31, 2009 $196.9M $216.9M $220.2M $213.6M November 30, 2009 $203.0M $223.3M $226.7M $219.9M December 31, 2009 $205.2M $225.3M $228.7M $221.9M
Braidwood and Byron Question 2 As of November 30, 2009, Exelon has not resolved its shortfall in decommissioning funding assurance for Braidwood Units 1 and 2 and Byron Units 1 and 2 per NRC requirements. Provide additional financial assurance in an
amount that will eliminate the decommissioning funding assurance shortfall for 2 Braidwood Units 1 and 2 and Byron Units 1 and 2 prior to December 31, 2009.
Response to Question 2
EGC intends to calculate any shortfall based on the decommissioning trust fund values and the estimated decommissioning costs as of December 31, 2009 as proposed in EGC's decommissioning funding assurance plan submitted in the Reference. Per this plan, EGC also intends to establish this additional financial guarantee by April 1, 2010, in accordance with NRC requirements. The dates set forth in the funding assurance plan were based on the time required to complete updated site-specific estimates for Braidwood Station, Units 1 and 2, and Byron Station, Units 1 and 2, and the time required to obtain the required internal approvals for any required additional financial guarantees, including approval by the Exelon Board of Directors.
Byron and Braidwood
Beginning in 1999, provide the year-end balances, dates, and amounts of
contributions made by Exelon into each of the decommissioning trust funds associated with Braidwood Units 1 and 2 and Byron Units 1 and 2. The data should be aggregated to show total contributions made.
