The Regulatory Function and Radioactive Waste Management OECD
The purpose of this brochure is to provide an easily accessible synopsis of the report The Regulatory Control of Radioactive Waste Management – Overview of 15 NEA Member Countries in order to provide a quick introduction to regulatory systems and an overview of current systems in NEA member countries. To that effect Chapter 2 identifies the elements generally associated with the process of regulation, Chapter 3 provides a comparative analysis of the regulatory arrangements in radioactive waste management across 15 NEA member countries, and Chapter 4 draws general observations.

Achieving the Goals of the Decommissioning Safety Case OECD
This report records the position of the WPDD on the safety of decommissioning and the task for providing a decommissioning safety case. Guidance is already available, both internationally and nationally [1,2,3] on the detailed technical, management and administrative requirements for the decommissioning of nuclear facilities. Such guidance tends currently to focus on radiological aspects, reflecting its development from the safety case for the operational phase. The decommissioning phase, however, introduces some wider issues, or at least a change of emphasis on existing issues, and it is against this background that the WPDD started to review the key points that need to be addressed specifically for decommissioning safety and to consider whether there is sufficient guidance for the increased level of decommissioning activity expected over the next decade or so.

VVER-1000 MOX Core Computational Benchmark Eugeny Gomin, Mikhail Kalugin, Dmitry Oleynik
This report presents the VVER MOX Core Computational Benchmark Specification and Results, which was proposed as a benchmark within the OECD/NEA Expert Group on Reactor-based Plutonium Disposition (TFRPD). Benchmark results, obtained using three computer codes, are presented. The codes include: the MCU Monte Carlo code (Kurchatov Institute, Russian Federation), RADAR (Kurchatov Institute, Russian Federation), and the MCNP Monte Carlo code (GRS, Germany). The codes use different methods and different nuclear data. A comparison of the results shows good agreement among the various codes.

Physics and Safety of Transmutation Systems OECD
This status report begins by providing a clear definition of partitioning and transmutation (P&T), and then describes the state of the art concerning the challenges facing the implementation of P&T, scenario studies and specific issues related to accelerator-driven system (ADS) dynamics and safety, long-lived fission product transmutation and the impact of nuclear data uncertainty on transmutation system design.
