Safety objectives of emergency heat removal systems (EHRS) 

In unlikely cases of unavailability of the water/steam system e.g. due to  

Various EHRS design concepts have been proposed and experimental and analytical studies have been carried out in a number of countries. 

For different LMFR types and sizes the following main concepts can be defined  

Decay heat removal (DHR) via immersed decay heat exchangers (DHXs) in the hot or cold pool, intermediate sodium loop, sodium-air-cooler,
