Disposal of Spent Nuclear Fuel and High-level Radioactive Waste
Disposal of Spent Nuclear Fuel and High-level Radioactive Waste
The characteristics of spent nuclear fuel and high-level waste are described, and options for permanent disposal that have been considered are described. These include:
•disposal in a mined geological formation,
•disposal in a multinational repository, perhaps on an unoccupied island,
•by in situ melting, perhaps in underground nuclear test cavities,
•sub-seabed disposal,
•disposal in deep boreholes,
•disposal by melting through ice sheets or permafrost,
•disposal by sending the wastes into space, and
External Criticality Risk of Immobilized Plutonium Waste Form in a Geologic Repository
External Criticality Risk of Immobilized Plutonium Waste Form in a Geologic Repository
This technical report provides an updated summary of the waste package (WP) external criticalityrelated
risk of the plutonium disposition ceramic waste form, which is being developed and
evaluated by the Office of Fissile Materials Disposition of the U.S. Department of Energy (DOE).
The ceramic waste form consists of Pu immobilized in ceramic disks, which would be embedded
in High-Level Waste (HLW) glass in the HLW glass disposal canisters, known as the "can-incanister"
Disposal Criticality Analysis for Aluminum-based Fuel in a Codisposal Waste Package - ORR and MIT SNF - Phase II
Disposal Criticality Analysis for Aluminum-based Fuel in a Codisposal Waste Package - ORR and MIT SNF - Phase II
The objective of this analysis is to characterize the criticality safety aspects of a degraded Department of Energy spent nuclear fuel (DOE-SNF) canister containing Massachusetts Institute of Technology (MIT) or Oak Ridge Research (ORR) fuel in the Five-Pack Defense High-Level Waste (DHLW) waste package to demonstrate concept viability related to use in the Mined Geologic Disposal System (MGDS) environment for the postclosure time frame.

WP 2 Appendix 10 Balance of Power: Principles and Good Practices for Local Stakeholders to Influence National Decision-making Processes
Our basic position is that the outcomes of policy-making in radioactive waste management (RWM) should be driven by the will of the people through democratic processes. Achieving this inclusiveness requires good practices to increase local influence on what is essentially a national policy process. However inclusiveness poses significant practical problems; can society afford lengthy and costly consultation processes, often perceived as inefficient and ineffective?

WP 3 Quality of decision-making process Proposed Framework for Decision-making Processes
The long-term governance of radioactive waste is complex socio-technical issue. The disposition of radioactive waste is decided on ethical grounds, having to take into account a variety of other dimensions (society, economy, ecology, politics, time, space, and technology). Thereto, a study of variants is required. Decision theory, in principle, takes diverse options as a starting point begin as the basis of a decision.

WP 2 Appendix 7 Influence of Local Communities on Decision Processes: Experience of Copeland and Shetland Islands
WP 2 Appendix 7 Influence of Local Communities on Decision Processes: Experience of Copeland and Shetland Islands
The focus of this case study is the concerns of two communities affected, albeit in different ways, by radioactive waste management and the decommissioning of nuclear installations. These are communities affected by the decisions of nuclear operators, regulators and national policy makers. As such they interact with these organisations and quite naturally they are concerned about their long-term sustainability.

Technical Basis Report For Surface Characteristics, Preclosure Hydrology, And Erosion
Technical Basis Report For Surface Characteristics, Preclosure Hydrology, And Erosion
This study presents a synthesis of information and interpretations relevant to surficial processes at the Yucca Mountain Site. The report is part of the technical basis which will be used to evaluate the suitability of Yucca Mountain, Nevada, as a site for a mined geologic repository for the permanent disposal of high-level radioactive waste and spent nuclear fuel. It provides a description of the surface characteristics, preclosure hydrology, and erosion at the Yucca Mountain Site. This report will provide the technical basis to evaluate three technical guidelines from the U.S.
