2 Introduction  The Office of National Transportation (ONT) has made steady progress in establishing the groundwork to develop the transportation infrastructure.  Today, I will address: – Requirements for cask systems; – Cask integration efforts to ensure interface with the Yucca Mountain repository and utility sites; – Capabilities of existing casks to accommodate commercial spent nuclear fuel (SNF) and Department of Energy (DOE) SNF and high-level radioactive waste (HLW); and – Ability of commercial reactor sites to accommodate transportation cask systems.

3 Cask System Requirements  DOE has a preference for purchasing cask systems with current Nuclear Regulatory Commission (NRC) certifications.  DOE has a bias toward cask systems that keep radiation exposure to workers and the public as low as reasonably achievable (ALARA) via design or procedure.  DOE has a preference for cask systems that provide the maximum flexibility in terms of facility and fuel compatibility.  ONT facilitated a meeting to bring the Office of Repository Development (ORD) and cask vendors together to discuss repository and transportation cask interfaces.

4 Transportation Cask Interface with the Repository  The Yucca Mountain repository must receive a license issued by the Nuclear Regulatory Commission (NRC) in accordance with 10 CFR Part 63.  10 CFR Part 71 will govern the transportation casks.  To facilitate waste receipt, coordination efforts are underway to utilize transportation casks that will be compatible with the Yucca Mountain repository. –10 CFR 63 regulations may impose additional performance requirements upon casks utilized at the repository.  We are working with the repository to get data from the cask vendors to make sure the systems are compatible.

6 Cask Capability Assessment Reports  Purchase orders to perform cask capability assessments (CCA) were placed with vendors possessing NRC Certificates of Compliance (C of C). –All reports were received by August 28.  Vendor meetings held in late August and early September provided an opportunity to discuss the data and the vendors’ ability to meet ONT’s needs. –Vendors explained the analysis and/or modifications necessary to accommodate the maximum amount of the SNF and high-level waste (HLW) inventory.

8 Current Cask Size Envelope  For ORD planning purposes, all new casks purchased will fall within this envelope:

9 Facility Interface Data Sheets Summary  Eighty-nine out of 119 facilities have provided responses to the Facility Interface Data Sheets (FIDS) sent out in March  Although preliminary, FIDS responses point out a number of facility infrastructure limits that will influence cask selection and transportation planning.  About 40 reactor sites are currently anticipated to have a crane capacity of 120 tons or less.  Crane lifting capacity will be a primary factor in determining the type of shipping cask a facility can utilize.

11 Conclusions Regarding Existing Casks’ Ability to Accommodate Commercial SNF  The CCA reports indicated that no single cask could transport more than about 40% of the commercial SNF inventory under the conditions of current C of Cs.  However, analysis of the reports has shown that a suite of casks from several vendors could transport upwards of 60% of the projected commercial inventory.  Preliminary analysis by the vendors indicated that CoCs could be modified to accommodate more than 90% of the commercial SNF inventory, based on SNF characteristics alone.

15 Transportation Cask Interface with Commercial Reactor Sites  Preliminary evaluation of available data and information sources indicates that 125-ton transportation casks may not be suitable at a number of sites.  The Department of Energy (DOE) is developing strategies to address these sites, including possible design of smaller, bare fuel transportation cask systems (100-, 70-, or 60- ton, for example).  DOE is also evaluating other concepts or solutions such as utilizing smaller transfer casks to load large transportation casks.

16 Transportation Cask Interface with DOE Sites  Casks exist today that are technically capable of transporting DOE spent nuclear fuel (SNF) and high-level radioactive waste (HLW). –Generally, the thermal, structural, and shielding requirements for commercial SNF bound those of the DOE SNF and HLW.  DOE is developing a performance specification that will delineate the characteristics and parameters of DOE SNF and HLW in order to solicit transportation package designs for this material.

17 Conclusions Regarding DOE SNF and HLW  Casks exist today that are technically capable of transporting DOE SNF and HLW. –Generally, the thermal, structural, and shielding requirements for commercial SNF bound those of the DOE SNF and HLW.  New internal basket designs would be developed to accommodate the DOE canisters. –Certificate modifications will be required for the new baskets.  During the first 5 years of shipping operations, no new (Category C) casks will need to be developed for DOE material.

18 Rolling Stock Performance Requirements  DOE is currently working to meet the Association of American Railroads’ (AAR) Performance Specification, S-2043, for trains used to carry HLW.  ONT has engaged Transportation Technology Center, Inc. (TTCI) to provide preliminary evaluation of several standard and premium railcar truck designs.  Results indicated that off-the-shelf truck designs would not meet all S-2043 requirements.  However, TTCI indicates that specific design and tuning of the trucks and suspensions as part of railcar system should improve results and provide acceptable performance.

19 Nevada Rail Line  Work on the Nevada Rail Alignment Environmental Impact Statement (EIS) is moving forward.  DOE Received over 4,000 comments during scoping meetings.  Several alternative routes were suggested by the public. –The EIS will be delayed slightly to perform engineering work on the alternative routes to evaluate their feasibility.

20 Fleet Management and Support Facilities  Locations of the Fleet Management Facility (FMF) and other support facilities are being evaluated in the Nevada Rail Alignment EIS.  Preliminary work to provide input into the EIS has been performed.  The FMF may be completed after the opening of Yucca Mountain. –Operations can begin using commercially available facilities.

21 Conclusions  ONT has many challenges ahead in procuring the transportation infrastructure to support repository operations.  Many drivers will influence the development of the transportation infrastructure.  ONT is emphasizing flexibility in its procurement approach in order to adapt to external influences and changing requirements.
