Abstract

Molten boron trioxide (B2O3) is introduced to a nuclear fission environment resulting in a neutron poison reaction and the eventual full shut down of an active nuclear fission reaction within a nuclear reactor pressure vessel, pressure chamber, or equivalent construction that may be subject to fission reaction events, such as a spent fuel pond or reprocessing facility. The boron trioxide may be added in a pre-melted liquid form, or derived from boric acid (H3BO3) introduced directly into the high temperature nuclear fission environment. The boron trioxide or boracic acid should be arranged to completely fill the reaction vessel or chamber so as to isolate and enclose any exposed or broken off fuel components, seal any breach in the vessel or chamber, and negate the possibility of any combustible gas ignition.
