Advance Reactor Concepts Technical Review Panel Public Report

The Office of Nuclear Energy supports research and development for advanced reactor technologies. This report documents the results of the 2014 Technical Review Panel (TRP) review of seven advanced reactor concepts. The intent of the process was to identify R&D needs for advanced reactor concepts in order to inform Department of Energy (DOE) Office of Nuclear Energy R&D investment decisions.

Assessment of Disposal Options for DOE-Managed High-Level Radioactive Waste and Spent Nuclear Fuel

The Assessment of Disposal Options for DOE-Managed High-Level Radioactive Waste and Spent Nuclear Fuel report assesses the technical options for the safe and permanent disposal of high-level radioactive waste (HLW) and spent nuclear fuel (SNF) managed by the Department of Energy. Specifically, it considers whether DOE-managed HLW and SNF should be disposed of with commercial SNF and HLW in one geologic repository or whether there are advantages to developing separate geologic disposal pathways for some DOE-managed HLW and SNF. The report recommends that the Department begin implementation of a phased, adaptive, and consent-based strategy with development of a separate mined repository for some DOE-managed HLW and cooler DOE-managed SNF.

Results of Stainless Steel Canister Corrosion Studies and Environmental Sample Investigations.

This report documents experimental work evaluating localized corrosion of container and canister materials performed at Sandia National Laboratories. The report also documents the results of analyses of the dust samples collected by the EPRI-led in-service inspections of dry storage canisters at existing ISFSIs (Hope Creek NJ, and Diablo Canyon CA).

Used Fuel Disposal in Crystalline Rocks: Status and FY14 Progress

The objective of the Crystalline Disposal R&D work is to advance our understanding of long-term disposal of used fuel in crystalline rocks and to develop necessary experimental and computational capabilities to evaluate various disposal concepts in such media.  The major accomplishments during the year include: 1)  R&D plan was developed for used fuel disposal in crystalline rocks; 2)  established  a generic reference case for crystalline disposal media; 3) developed and applied THMC models to the analysis of coupled EBS processes in bentonite-backfilled repositories; 4) examined t

FY14 Status Report: CIRFT Testing Results on High Burnup UNF

This report provides a status of the performance of a systematic study of used nuclear fuel (UNF, also known as “spent nuclear fuel” [SNF]) integrity under simulated transportation environments using the Cyclic Integrated Reversible-Bending Fatigue Tester (CIRFT) hot-cell testing technology developed at Oak Ridge National Laboratory (ORNL) in August 2013. Under Nuclear Regulatory Commission (NRC) sponsorship, ORNL completed four benchmark tests, four static tests, and twelve dynamic or cycle tests on H. B. Robinson (HBR) high burn-up (HBU) fuel.

Effects of Multiple Drying Cycles on HBU PWR Cladding Alloys

The purpose of this research effort is to determine the effects of canister/cask vacuum drying and storage on radial hydride precipitation in high‐burnup (HBU) pressurized water reactor (PWR) cladding alloys during cooling for a range of peak drying‐storage temperatures, internal gas pressures, and hoop stresses. The HBU PWR cladding alloys have a wide range of hydrogen contents and varying hydride morphology after in‐reactor service.

International Collaboration Activities in Different Geologic Disposal Environments

This report describes the current status of international collaboration regarding geologic disposal research in the Used Fuel Disposition (UFD) Campaign.  To date, UFD’s International Disposal R&D Program has established formal collaboration agreements with five international initiatives and several international partners, and has started several specific collaborative R&D activities.  These international activities include testing and modeling studies and address the following key research areas:  Near-Field Perturbation, Engineered Barrier Integrity,  Radionuclide Transport, and

Database for Regional Geology, Phase 1– A Tool for informing Regional Evaluations of Alternative Geologic Media and Decision Making

The report describes implementation and planning of websites that allow visualization or manipulation of data in the UFD GIS Database; e.g., the distribution of crystalline rock, basement depth, and salt and shale formations within the contiguous United States, and visualizations of the relationships between geologic media and selected natural and cultural features pertaining to potential siting guidelines for repository siting.

Documentation of Hybrid Hydride Model for Incorporation into Moose-Bison and Validation Strategy

This report documents the development, demonstration and validation of a mesoscale, microstructural evolution model for simulation of zirconium hydride d-ZrH1.5 precipitation in the cladding of used nuclear fuels that may occur during long-term dry storage.  The precipitation and growth of zirconium hydrides during dry storage is one of the most likely fuel rod integrity failure mechanisms either by embrittlement or delayed hydride cracking of the cladding.  The model being documented in this work is a computational capability for the prediction of hydride formation in different claddings

Normal Conditions of Transport Truck Test of a Surrogate Fuel Assembly

This report describes a test of an instrumented surrogate PWR fuel assembly on a truck trailer conducted to simulate normal conditions of truck transport.   The purpose of the test was to measure strains and accelerations on a Zircaloy-4 fuel rod during the transport of the assembly on the truck. This test complements tests conducted in FY13 in which the same assembly was placed on a shaker and subjected to vertical vibrations and shocks simulating truck transport.  The strains measured on the instrumented Zircaloy-4 rod over a 40.2 mile route never exceeded 150 μin./in.
