SEVERE NUCLEAR ACCIDENT PROGRAM (SNAP) A REAL TIME DISPERSION MODEL

The Chernobyl nuclear accident in April/May 1986 showed that Norway was not well prepared for this kind of emergency situation1. Scientists who had relevant information felt frustrated because there was no clear answer to the question: where and how their information should be delivered, assessed and synthesized1. In addition, there was no dispersion model implemented in an operational environment, ready to simulate and forecast atmospheric transport and deposition of the radioactive pollutants over Europe based on real-time meteorological data. This was also the situation in most countries in Europe2.
