Radiation Protection During Decommissioning – Are There Special Needs?

The first area of the session addresses protection of personnel engaged in decommissioning activities. Decommissioning activities are associated with large changes in the NPP configuration. The overall remaining radioactive inventory will shift. Systems are taken out of service. Originally confined radioactive sources become open sources due to the fact that systems are decommissioned. The second area of discussion deals with clearance of radioactive material and public acceptance. This topic addresses the question of “conditional” and “unconditional” release of components and material. It is not only a question about clearance levels but also about public acceptance of receiving cleared, i.e. non-nuclear, waste at normal landfill sites. To all decommissioning activities, the ALARA approach applies. German rules and regulations, e.g. Radiation Protection Ordinance, various KTA rules, and international rules (BSS) and recommendations issued e.g. by IAEA or EU provide an appropriate framework for workers protection. Is there a need for specific “German decommissioning rules”?

The final closure of a site requires the removal of all material. The largest amount originating  from the demolition of buildings is non-nuclear waste. Some amount of waste has gone through the clearance. Some amount of waste was never subject to nuclear regulatory surveillance because it  originates from office buildings, cooling towers, turbine buildings (in PWR plants), pumping station structures and others. This session tries addressing some of these questions and tries providing some answers. Some of the presentation will give an interesting introduction and the answer might be gained during lively discussions between the session participants.

Coordinator: Dr.-Ing. L. Mohrbach, VGB PowerTech e.V., Germany

The operation of nuclear power plants involves a wide scope of specialized areas of expertise, from materials to human factors. Beyond daily business, some background information from different fields of operational activities might not only be regarded as personally worthwhile but may also be well suited to complement the general knowledge base for nuclear.
