Molten salt reactor containment

A system comprising

• an integral molten salt reactor comprising
• an integrally constructed vessel defining a critical region and a subcritical region,
• a reactor core disposed within the critical region, and
• salt routing floors disposed within the subcritical region, wherein the reactor core and the salt routing floors are fully enclosed within the integrally constructed vessel;
• and
• a sealed containment structure defining a containment volume about the integrally constructed vessel and comprising a fission product adsorbing/absorbing material positioned within the containment volume and outside of the integrally constructed vessel.

A system comprising

• a sealed containment structure defining a containment volume, the sealed containment structure including a fission product adsorbing/absorbing material disposed within the containment volume;
• an integral molten salt reactor positioned within the containment volume and fully encompassed by the sealed containment structure, the integral molten salt reactor permitting circulation of a fuel salt within a sealed spaced therein being heated by fission reactions, and allowed for the export of heat from said fuel salt,
• wherein the fission product adsorbing/absorbing material
• extends throughout the containment volume and encompasses the integral molten salt reactor, and
• cooperates with the sealed containment structure to retain fission gasses upon a release event of said fission gasses from the integral molten salt reactor.
