Abstract

The HTR-Module is a power reactor with specially favourable safety features. This is evident by the fulfillment of the following claims: The maximum possible environmental damage is limited and can be quantified. The consequences of all credible but extremely hypothetical accidents are restricted to the plant site and have no relevant offsite effect. The maximum offsite radiation doses are below the values prescribed for basic design accidents by article 28.3 of the German Radiation Protection Ordinance. In consequence there is no need to provide strategies for public sheltering or even evacuation and no need to prohibit the consumption of agricultural products. By the fulfillment of these claims the HTR-Module can be regarded as not to be burdened with a residual risk.
