ABSTRACT:
A method of removing the decay heat of radioactive fission products from a gas-cooled high temperature nuclear reactor in an emergency situation wherein a fault or a combination of faults results in the normal operational systems of the reactor not being able to remove the decay heat satisfactorily, comprises introducing water into the reactor core. Preferably the water is completely desalinated water which is introduced into the core from above. Absorber material may also be mixed with the water before it is introduced into the core to effect permanent shutdown of the reactor by absorbing free neutrons within the core.
