EURISOL Desktop Assistant Toolkit (EDAT): A modeling,simulation and visualization support to the preliminary radiological assessment of RIB projects

摘要

The paper describes an approach taken within the EURISOL-DS project (European Isotope Separation Online Radioactive Ion Beam Facility) to a number of safety and radioprotection issues raised by the advent of radioactive ion beam facilities in the cutting edge area of particle accelerators. The ensuing solution emerged from a collaborative effort of the investigating team-in-charge, affiliated with the Horia Hulubei National Institute of Physics and Nuclear Engineering in Bucharest, with expert colleagues at the Physics Institute in Vilnius, and at CERN, within the participation in the EURISOL-DS project, Sub-Task B: Radiation, Activation, Shielding and Doses of the Safety and Radioprotection, Task 5. The work was primarily geared towards the identification of knowledge and data in line with validated, accepted and nationally/internationally recommended methods and models of radiological assessment applied within the nuclear power fuel cycle, deemed to be suitable for assessing health and environmental impact of accelerator operations as well. As a result, a computer software platform code-named “EURISOL Desktop Assistant Toolkit” was developed. The software is, inter alia, capable to assess radiation doses from pure or isotopically mixed open or shielded point sources; emergency response-relevant doses; critical group doses via complex pathways, including the air, the water, and the food chain and derived release limits for the normal, routine operations of nuclear facilities. Dedicated data libraries and GIS (Geographic Information System) facilities assist the input/output operations.
