SUBJECT:

INFORMATION REQUEST TO SUPPORT UPCOMING INSPECTION OF PREOPERATIONAL TESTING OF AN INDEPENDENT SPENT FUEL STORAGE INSTALLATION AT THE BRAIDWOOD STATION

Dear Mr. Pacilio,

This letter is to request information to support our inspection of the Pre-Operational Testing of an Independent Spent Fuel Storage Installation (ISFSI) beginning February 28, 2011, at the Braidwood Station. This inspection will be performed in accordance with U.S. Nuclear Regulatory Commission (NRC) Inspection Procedures 60854.1 and 60856.1.

The inspection will take place in four parts: 1) an off-site review of your calculations used to support heavy loads movements throughout the site with on-site inspection of the structures;

2) an on-site review of your Title 10 of the Code of Federal Regulations (CFR) 72.212 Report;

3) an off-site review of procedures, evaluations, and programs to demonstrate site readiness to load spent fuel; and 4) on-site observations of dry run operations.

Experience has shown that these inspections are resource intensive both for the NRC inspectors and the utility staff. In order to minimize the impact that the inspection has on the site and to ensure a productive inspection, we have enclosed a list of documents required for the inspection.

The document request is split into two sections. Section A requests documents associated with calculations used to support heavy loads movements throughout the site. Please provide this information to the NRC Region III office no later than February 28, 2011. Section B requests documents covering the balance of the inspection. Please provide this information to the NRC Region III office no later than the first NRC dry run demonstration. The documents requested are necessary to ensure the inspection team is adequately prepared for the inspection. The information may be provided either electronically or in hard copy.

If there are any questions about the material requested, or the inspection in general, please do not hesitate to call or e-mail Mr. Matthew Learn at 630-829-9603 or Matthew.Learn@nrc.gov.

In accordance with 10 CFR 2.390 of the NRCs Rules of Practice, a copy of this letter will be available electronically for public inspection in the NRC Public Document Room or from the

M. Pacilio NRC's Agencywide Documents Access and Management System (ADAMS), accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html.

This letter does not contain new or amended information collection requirements subject to the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.). Existing information collection requirements were approved by the Office of Management and Budget, Control Number 3150-0011.

The NRC may not conduct or sponsor, and a person is not required to respond to, a request for information or an information collection requirement unless the requesting document displays a currently valid Office of Management and Budget Control Number.

Sincerely,

/RA/

Requested Information for NRC Inspection of Pre-Operational Testing of an Independent Spent Fuel Storage Installation (ISFSI) - Section A

1. Design documentation, design calculations, safety evaluations (72.48 and 50.59), and resultant structural modifications that demonstrated the fuel cask could be safely placed into the spent fuel pool and loaded with spent fuel, lifted from the spent fuel pool and placed on the designated laydown areas, transferred to the transport vehicle, and transported to the ISFSI.

2. Current spent fuel cask drop analysis or single failure proof crane evaluation including the trolley, the bridge, and the support structure.

3. Other supporting documents that demonstrate equipment to maintain safe shutdown will be unaffected (i.e. calculations associated with the spent fuel cask drop analysis) and that potential off-site releases at the exclusion boundary will be within 10 CFR part 100 limits after a postulated spent fuel cask drop (if applicable).

4. Calculations for rigging and special lifting devices associated with lifting the spent fuel storage and transfer casks.

5. Documents that establish the total lift weights for loaded spent fuel storage and transfer casks.

6. Site procedures associated with Control of Heavy Loads, transport of loaded spent fuel storage and transfer casks during plant operations, and any contingency actions taken to mitigate the consequences of a spent fuel storage or transfer cask drop.

7. An electronic copy of the Braidwood Station UFSAR.
