A parametric survey of severe accident cosequences for a medium-sized advanced type reactor

The first nuclear power plant in Israel will probably belong to a new generation of reactors. Different design concepts are currently being studied, such as the ALWR and the HTGR. It is widely accepted that a new type of reactor will possess some passive safety features, such as low power density (compared to the current commercial reactors) and smaller total power. In the highly improbable case of a severe accident, these safety features should assure lower off-site release fractions for the most of the radionuclides, as well as lower release rates. (author)
