Standardized Canisters for Spent Nuclear Fuel: Their Potential Impact and a Proposed Path Forward

This paper describes an evaluation completed in Fiscal Year 2016 (FY16) that investigates using standardized triple-purpose (storage, transportation, and disposal) canisters within an integrated waste management system (IWMS). The IWMS in this particular evaluation is focused on management of commercial spent nuclear fuel (SNF). Incorporation of a standardized canister system into the IWMS provides an opportunity to develop an integrated approach to address storage, transportation, and disposal issues. Regardless of implementation timing and method, deployment of such a canister system could cause significant system-wide impacts. Over the past few years, a number of system analyses have been performed for the US Department of Energy (DOE), Office of Nuclear Energy (NE) using logistic simulations to evaluate the impacts of incorporating these smaller canisters into the IWMS. Furthermore, these simulations predict the amount of resources (e.g., staff, canisters/casks, railcars, facilities), the size of facilities, the timing of operations, and rough-order-of-magnitude (ROM) cost estimates.

U.S. Sodium Fast Reactor Codes and Methods: Current Capabilities and Path Forward

The United States has extensive experience with the design, construction, and operation of sodium cooled fast reactors (SFRs) over the last six decades. Despite the closure of various facilities, the U.S. continues to dedicate research and development (R&D) efforts to the design of innovative experimental, prototype, and commercial facilities. Accordingly, in support of the rich operating history and ongoing design efforts, the U.S. has been developing and maintaining a series of tools with capabilities that envelope all facets of SFR design and safety analyses. This paper provides an overview of the current U.S. SFR analysis toolset, including codes such as SAS4A/SASSYS-1, MC2-3, SE2-ANL, PERSENT, NUBOW-3D, and LIFE-METAL, as well as the higher-fidelity tools (e.g. PROTEUS) being integrated into the toolset. Current capabilities of the codes are described and key ongoing development efforts are highlighted for some codes.
