ABSTRACT:
The shutting down of a gas cooled nuclear reactor is effected by causing boron or other neutron poisons to deposit upon and adhere to reactor core surfaces. The introduction of the poison and other necessary substances into the core is achieved by spilling numerous coherent pellets into the core vessel; the pellets containing a substance which changes state at a predetermined temperature resulting in disintegration of the pellets and deposition of their constituents.
