Important thermal constraints for mined geologic disposal are to limit degradation of engineered ... more Important thermal constraints for mined geologic disposal are to limit degradation of engineered materials close to waste packages, and to limit thermal damage to host rock. Measures available to limit temperatures include: 1) selecting host rock with superior thermal properties, 2) decay storage before emplacement, 3) preclosure repository ventilation, 4) smaller waste packages, and 5) larger package and drift spacings. This study has investigated these measures and produced a set of reference disposal concepts that can be used to guide the geologic disposal R&D program, and logistical planning for waste disposal. While any of these reference concepts could deliver safe long-term waste isolation, use of the enclosed modes (popular internationally) would require small waste packages (e.g., 4-PWR size), while disposal of larger packages (12-PWR up to 32-PWR sizes) could require either salt media or emplacement in hard rock. One exception is that larger packages could be disposed of i...

To assess the potential performance of conceptual repository designs for the combinations of waste form and geologic environment, a master set of Features, Events, and Processes (FEPs) has been developed and evaluated. These FEPs are based on prior lists developed by the Yucca Mountain Project (YMP) and the international repository community. The objective of the UFD FEPs activity is to identify and categorize FEPs that are important to disposal system performance for a variety of disposal alternatives (i.e., combinations of waste forms, disposal concepts, and geologic environments). FEP analysis provides guidance for the identification of (1) important considerations in disposal system design, and (2) gaps in the technical bases. The UFD FEPs also support the development of performance assessment (PA) models to evaluate t...

The planning, construction, and operation of a nuclear disposal facility is a long-term process that involves engineered barriers that are tailored to both the geologic environment and the waste forms being emplaced. The UFD Campaign is considering a range of fuel cycles that in turn produce a range of waste forms. The UFD Campaign is also considering a range of geologic media. These ranges could be thought of as adding uncertainty to what the disposal facility design will ultimately be; however, it may be preferable to thinking about the ranges as adding flexibility to design of a disposal facility. For example, as the overall DOE-NE program and i...

The goal of the design tradeoff study is to identify repository design options that enable use of large waste packages. Concepts evaluated include those with pre-closure ventilation (open mode) as well as those with backfill installed at the time of waste emplacement (enclosed mode). Open mode systems maintain an air gap between the waste package and the rock (drift or borehole) wall, across which the primary mode of heat transfer is thermal radiation. In enclosed mode systems, there are multiple layers of the Engineered Barrier System (EBS) between the waste package and the rock wall, such as buffer, envelope, backfill, and a liner. DSEF includes user-friendly options to facilitate the documentation of conceptual repository design alternatives for a wide assortment of waste forms, geologic environments, and repositor...

It is a knowledge management system that allows the user to intelligently access and draw data from a case library of hundreds of completed thermal analyses (currently 300 cases in the library), and draw input from databases of material properties and repository development cost data (currently the data in these databases is drawn from more than 100 references). The core functionality of DSEF is provided by a Microsoft Office Excel 2010 workbook with macros and form controls that create a structured environment. The workbook walks the user through the steps of creating the input data required to perform disposal system evaluations by interfacing with external...

The waste generally has higher activity per unit mass of heavy metal, but much lower activity per unit energy generated. The very long-term radioactivity is dominated by fission products. Simple scaling calculations suggest that the dose from a repository containing such waste would be dominated by 129I, 135Cs, and 242Pu. Use of such a system for generating energy would greatly reduce the need for repository capacity
