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.

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.
Guidance on the Selection of PTA Tools: For Stakeholders involved in Radioactive Waste Governance WP1
Guidance on the Selection of PTA Tools: For Stakeholders involved in Radioactive Waste Governance WP1
This research on "e;Guidance on the selection of PTA tools for stakeholders involved in radioactive waste governance"e; was performed under the umbrella of COWAM2-'Work Package 1' (WP1). Through a dialogue on enhancing involvement at a local level, WP1 allows local stakeholders to examine the issues they face in building a democratic local governance process. WP1 also tests how Participatory Technology Assessment (PTA) methods can offer a consensual framework and a platform for deliberative co-decision among scientific and societal actors at the local level.
Tools for Local Stakeholders in Radioactive Waste Governance: Challenges and Benefits of Selected PTA Techniques WP1
Tools for Local Stakeholders in Radioactive Waste Governance: Challenges and Benefits of Selected PTA Techniques WP1
The investigation consists of three parts and shall provide an input to the – empirical – PTA-2 study to be undertaken by SCK•CEN (called “lens”):<br>A. Compilation of – selected – existing PTA methods and procedures identifying requisites, practices, benefits, and challenges to answer the key questions in the context of WP1 about a PTA “toolbox”: “What can you apply, when can you apply, and what is needed to apply?” The multi-dimensional context of a possible “PTA situation” is analysed; suitable and nonsuitable methods, techniques and procedures are discussed.<br>B.
Nuclear waste management from a local perspective: Reflections for a Better Governance Final Report
Nuclear waste management from a local perspective: Reflections for a Better Governance Final Report
During the 1990s, nuclear waste programmes in nearly every concerned country met many difficulties. Nuclear waste management was seen as a technical issue, and the local communities were only involved in the last stage of the decision-making process when almost all components of the decision were already fixed. The management of high level radioactive waste is now recognised as a complex decision-making process entailing technical, ethical, social, political and economic dimensions where no solution can be reached solely on the basis of technical considerations.
