This report describes a novel approach developed at the Oak Ridge National Laboratory
(ORNL) for the estimation of the uncertainty in the prediction of the neutron multiplication factor
for spent nuclear fuel. This technique focuses on burnup credit, where credit is taken in criticality
safety analysis for the reduced reactivity of fuel irradiated in and discharged from a reactor.
Validation methods for burnup credit have attempted to separate the uncertainty associated with
The objective of this calculation is to provide the uncertainty term for fission product and minor actinides which contributes to the determination of the critical limit for burnup credit calculations. The scope of this calculation covers PWR and BWR spent nuclear fuel. This activity supports the Criticality Department's validation of burnup credit. The intended use of these results is in future Criticality Department calculations and analyses.
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?
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.

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.
