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.

Evaluation Of Used Fuel Disposition In Clay-Bearing Rock

Radioactive waste disposal in shale/argillite rock formations has been widely considered given its desirable isolation properties, e.g., low permeability, potential geochemically reduced conditions, anomalous groundwater pressures, and widespread geologic occurrence.

Waste Form Degradation Model Integration for Engineered Materials Performance

The collaborative approach to the glass and metallic waste form degradation modeling activities includes process model development (including first-principles approaches) and model integration—both internally among developed process models and between developed process models and PA models, and cross campaign integration between activities in the Used Fuel Disposition (UFD) Campaign and the Separations (to be Materials Recovery) and Waste Forms (SWF=>MRWF) Campaign.  Experimental work is conducted within the UNFD area and results are utilized in development efforts.  The primary outputs

Secretarial Determination of No Adverse Material Impact for Uranium Transfers

The determination covers the Department’s sales or transfers of no more than 2,705 metric tons (MTU) of natural uranium (NU) or NU equivalent in a calendar year.  The proposed transfers include up to 650 MTU per year by the National Nuclear Security Administration in support of highly enriched uranium down blending activities, with the remainder of up to 2,705 MTU per year supporting accelerated cleanup activities by the Office of Environmental Management.

Modeling Fluid Flow in Natural Systems, Model Validation and Demonstration

Clay and granitic units are potential host media for future repositories for used nuclear fuel. The report addresses the representation and characterization of flow in these two media within numerical process models.  In low permeability crystalline rock, flow is primarily in relatively sparse networks of fractures.

Regional Geology: GIS Database for Alternative Host Rocks and Potential Siting Guidelines

The objective of this work is to develop a spatial database that integrates both geologic data for alternative host-rock formations and information that has been historically used for siting guidelines, both in the US and other countries.  The Used Fuel Disposition Campaign (UFDC) is considering three alternative geologic host rocks for mined repositories (granitic / crystalline, salt, and clay / shale) and crystalline basement rock for deep borehole disposal.  This report documents progress in populating a GIS Database with information concerning the distribution of alternative host rock
