Perspectives on Radioactive Waste Repository Monitoring

Heat Conduction in Radioactive Waste Repository

The paper presents some numerical tests for the temperature development around nuclear waste packages stored in vaults. We deal with two simplified models. In the first of them, a single long cylinder of the diameter 1 m is considered. It is filled with radioactive waste and surrounded by rock. The second model presents a long cuboidal package stored in a vault. The computation was carried out ...

Probabilistic risk analysis for a high-level radioactive waste repository.

A probabilistic risk analysis (PRA) for a high-level radioactive waste repository is very important since it gives an estimate of its health impacts, allowing comparisons to be made with the health impacts of competing technologies. However, it is extremely difficult to develop a credible PRA for a specific repository site because of large uncertainties in future climate, hydrology, geological ...

Applying imprecise probabilities to radioactive waste repository siting

The siting of a radioactive waste repository involves a series of decisions that require an integrated analysis of conflicting ecological, economical and social objectives. While making sure that these criteria are met, the main goal of such decisions is to ensure that the population and the environment are safe. According to IAEA (2007), the siting process consists of site selection and charac...

Clearance Level Discussion on Solid Radioactive Waste

INTRODUCTION In recent days, the words of clearance and clearance level are frequently used in the field of radioactive waste. This note is showing current Japanese situations on this issue and the discussion items. Clearance is defined as: removal of radioactive materials or radioactive objects within authorized practices from any further control by the Regulatory Authority. Clearance level is...
