Can sealing of rock hosting a repository for highly radioactive waste be relied on?

Three - dimensional behaviour of a prototype radioactive 1 waste repository in fractured granitic rock

Factors controlling rock–clay buffer interaction in a radioactive waste repository

The paper examines the interaction between host rock and a clay-based engineered barrier in the context of deep underground disposal of high-level radioactive waste. A large scale ‘‘in situ’’ heating test currently under way in the underground Grimsel Rock Laboratory (GRL; Switzerland) is adopted as a representative case for study. The main features of the behaviour of the rock/barrier system h...

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 ...

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 ...

Can self-reported height and weight be relied upon?

AIMS To assess whether self-reported height and weight [and body mass index (BMI)] can be used in workplace health promotion campaigns. METHODS Volunteers were instructed how to measure their weight, height and waist circumference (WC). Self-reported values were compared with direct measurements. Accuracy was assessed using simple (self-report - actual) and percentage difference [(self-report...
