Topical Report on Actinide-Only Burnup Credit for PWR Spent Nuclear Fuel Packages
Topical Report on Actinide-Only Burnup Credit for PWR Spent Nuclear Fuel Packages
A methodology for performing and applying nuclear criticality safety calculations, for PWR spent nuclear fuel (SNF) packages with actinide-only burnup credit, is described. The changes in the U-234, U-235, U-236, U-238, Pu-238, Pu-239, Pu-240, Pu-241, Pu-242, and Am-241 concentration with burnup are used in burnup credit criticality analyses. No credit for fission product neutron absorbers is taken. The methodology consists of five major steps. (1) Validate a computer code system to calculate isotopic concentrations of SNF created during burnup in the reactor core and subsequent decay.

WP 2 Appendix 10 Balance of Power: Principles and Good Practices for Local Stakeholders to Influence National Decision-making Processes
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?
Destructive Examination of 3-Cycle LWR Fuel Rods from Turkey Point Unit 3 for the CLIMAX-Spent Fuel Test
Destructive Examination of 3-Cycle LWR Fuel Rods from Turkey Point Unit 3 for the CLIMAX-Spent Fuel Test
The destructive examination results of five light water reactor rods from the Turkey Point Unit 3 reactor are presented. The examinations included fission gas collection and analyses, burnup and hydrogen analyses, and a metallographic evaluation of the fuel, cladding, oxide, and hydrides. The rods exhibited a low fission gas release with all other results appearing representative for pressurized water reactor fuel rods with similar burnups (28 GWd/MTU) and operating histories.

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
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.
