Implementation of an RN emergency system in Eastern Mediterranean
- | EC DG Home Affairs, “Prevention and fight against Crime”- ISEC 2011

The aim of the project was the adaptation, installation and operation in Greece of computational decision support systems for emergencies related to nuclear and radiological events. Emphasis was given to all spatial scales, especially dispersion of radionuclides in urban areas.

The following activities have been carried out: (a) Installation of JRODOS in EREL / INRASTES / NCSRD and in the Greek Atomic Energy Commission (EEAE) (b) Customisation of Weather Research and Forecasting(WRF) system as provider of prognostic meteorological data for JRODOS (c) development of incident scenarios , (d) compilation of datasets for the Greek territory (e) definitions of countermeasures according to Greek regulations (f) implementation of databases and countermeasures in JRODOS (g) validation and testing of JRODOS and software (h) installation and customisation of the modelling system QUIC for dispersion of radionuclides in built-up urban areas and in confined spaces (i) development of scenarios for radionuclides releases in urban areas and confined spaces (j) compilation of datasets for urban areas in Greece (k) testing of the QUIC system.

Two events have been organised for the dissemination of the project results:
(1) A 2-days seminar on the topics: (a) Management of radiological and nuclear incidents for First Responders (b) Response to radiological contamination incidents from scrap metals and other materials addressed to the staff of companies handling scrap and to Customs officers
(2) A 2-days International Workshop on the implementation of Decision Support Tools in RN emergencies with the participation of experts and scientists from 16 European countries
