Title(s): Risks associated with human intrusion at radioactive waste disposal sites: proceedings of an NEA workshop, Paris, June = Risques liés a l'intrusion humaine sur les sites d'évacuation de déchets radioactifs: compte rendu d'une réunion de travail de l'AEN, Paris, juin Considerations Related to Human Intrusion in the Context of Disposal of Radioactive Waste – Results of the IAEA HIDRA Project Roger Seitz Senior Advisory Scientist P&RA Community of Practice – Aug SRNL‐MS‐‐ Acknowledge Members of Leadership Team Yumiko Kumano (IAEA), Lucy Bailey (UK NDA), Chris Markley (US NRC). Therefore, human intrusion events have been included that are associated with such activities. A radiological assessment model has been developed to analyse the impacts of potential human intrusion at the site. A key feature of the model is the representation of the spatial layout of the disposal site, including the engineered cap design and Author: Tim. Hicks, Tamara Baldwin, Richard Cummings, Trevor Sumerling.   OBJECTIVES OF THE STUDY Several studies have identified inadvertent human intrusion as the predominant contributor to risk of radioactive releases from a nuclear waste repository to the environ- ment []. Therefore, it is central to the performance of the site to determine the possible modes of intrusion, their likelihoods, and consequences.

from closing the commercial low-level radioactive waste (LLRW) disposal site in Richland, Washington. The report supports the Final Environmental Impact Statement (FEIS) being prepared by the Washington State departments of Health and Ecology. This report addresses long-term risk from the radiological waste disposed at the site. Managing radioactive waste is one of the main challenges in the NDA’s clean-up mission at its 17 early nuclear sites. Waste types vary widely in terms of quantity, hazard and characteristics. The UK Radioactive Waste Inventory (UKRWI) contains data for more than 1, individual waste streams that have arisen since the earliest days of the. The site must be marked. Aside from the legal requirement, the site will be indelibly imprinted by the human activity associated with waste disposal. We must complete the process by explaining what has been done and why. The site must be marked in such a manner that its purpose cannot be mistaken. Probabilistic risk and performance assessment for human intrusions faces two problems: The impossibility of creating an exhaustive list of intrusion scenarios and the lack of substantive knowledge about future societies and.

Recently, investigators modified the HRS to more realistically evaluate the risks posed by radioactive waste constituents. Although results from applying the modified HRS more» will be useful for comparing the priority of DOE sites to non-DOE sites, the methodology is still overly subjective. Tritiated water distributes itself through the environment as regular water does, into rivers and lakes, vegetation, wildlife, drinking water supplies, and eventually into humans. Human health hazards of nuclear waste include DNA damage, which often results in mutations that lead to cancer. the human-induced feps, i.e., the various human intrusion scenarios. the approach developed by the waste management community to try to understand and quantify the risks associated with geological disposal. The questions are whether scientists judge this to be an effective way of evaluating the suitability of the repository option and. Geological disposal should also “provide reasonable assurance that any risk from inadvertent human intrusion would be very small”. Repositories for the disposal of radioactive waste generally rely on a multi-barrier system to isolate the waste from the biosphere. This multi-barrier system typically comprises the .
