A Probabilistic Risk Assessment of Loss of Fuel Rod Cooling In the NRU 135 MW Research Reactor

Abstract

Probabilistic analysis techniques have been applied to calculate the risk of loss of fuel cooling leading to core melt in the NRU 135 MW (thermal) research reactor. No credit has been taken in this present study for the operation of the emergency cooling system. Whole body gamma doses to the public from a noble gas release resulting from a complete core melt have also been assessed using an appropriate dispersion model.
