Improved modelling of engineered barriers in LLW disposal facilities
Post-closure safety of SFR New faces
Safety assessments of low-level radioactive waste (LLW) disposal facilities often adopt a relatively simple and cautious approach to modelling radionuclide releases from the waste and engineered barriers. Quintessa has recently completed a project for Ontario Power Generation to develop and apply a more detailed representation of generic LLW disposal concepts and the associated processes. The results indicate that calculated doses can be reduced by more than an order of magnitude for most of the cases considered. For more information please contact Richard Little.
Quintessa has provided support to the Swedish Nuclear Power Inspectorate in evaluating SKB's case for the post-closure safety of the SFR disposal facility. The identification of key issues for the safety case was assisted by the use of independent performance assessment calculations using AMBER including the time-dependence of the environment over the next few thousand years as the land rises and the Baltic coastline recedes. For more information please contact Philip Maul.
Quintessa is pleased to welcome John Rees an associate consultant with broad experience of the whole radioactive waste life-cycle and Koji Hane who is a visiting engineer from Kajima Corporation in Japan.
