FY2015 Status Report: CIRFT Testing of High-Burnup Used Nuclear Fuel Rods from Pressurized Water Reactor and BWR Environments

High-burnup spent nuclear fuel cladding has a significant amount of microcracks and hydrides which will reduce the stress intensity required for crack growth.  Characteristics of cladding, fuel pellets, and interface between cladding and fuel pellets are likely to change after high burnup; these material modifications may impact the structural integrity and vibration response of SNF rods in transport.  The research object is to develop a system for testing the response of high-burnup fuel rods under simulated loading conditions.  The report provides recent test results derived from the Cyc

Evaluation for the Frequency of Gas Sampling for the High Burnup Confirmation Data Project

The report provides a technically based gas sampling frequency strategy for the High-Burnup (HBU) Confirmatory Data Project.  The evaluation of 1) the types and magnitudes of gases that could be present in the project cask, and 2) the degradation mechanisms that could change gas composition culminates in an adaptive gas sampling frequency strategy.  The adaptive strategy is compared against the sampling frequency that has been developed based on operational considerations.  Comparison evaluation of the Technically based and Operationally based sampling frequency strategies indicates there

International Nuclear Energy Research Initiative: 2013 Annual Report

Nuclear energy represents the single largest carbon-free baseload source of energy in the United States, accounting for nearly 20 percent of the electricity generated and over 60 percent of our low-carbon production. Worldwide, nuclear power generates 14 percent of global electricity. Continually increasing demand for clean energy both domestically and across the globe, combined with research designed to make nuclear power ever-safer and more cost-effective, will keep nuclear in the energy mix for the foreseeable future.

Summary of Investigations on Technical Feasibility of Direct Disposal of Dual-Purpose Canisters R1

This study has evaluated the technical feasibility of direct disposal in a geologic repository, of commercial spent nuclear fuel (SNF) in dual-purpose canisters (DPCs) of existing designs.  The investigation considered waste isolation safety, engineering feasibility, thermal management, and postclosure criticality control.  The 3-year study concludes that direct disposal is technically feasible for most DPCs, depending on the repository host geology.  Thermal management and postclosure criticality control are two important aspects of disposability, and both of these could be relatively sim
