Emergency Heat Removal System for the Secondary Loop of a Fast Sodium Reactor and its Efficiency Evaluation

Resumo

An emergency heat removal system (SAOT) that removes heat from the secondary loop of a fast sodium reactor by air cooling the surfaces of the piping and equipment of the heat-sink loops of the secondary loop is described and ways to optimize it are indicated. A method of evaluating the efficiency of such an SAOT is described, and the results of an evaluation for a fast sodium reactor are presented as an example showing that the system can be used in fast sodium reactors of any power capacity.
