Abstract
A system for reducing the possibility of leakage of fission gases from a nuclear reactor of the gas-cooled type or of a type utilizing a liquid coolant, for example a liquid metal with a cover gas above free surfaces of the coolant. The disclosed system reduces the leakage of fission gases from the cover gas through joints between a pressure vessel and a pressure vessel head in the nuclear reactor by installing an adsorbent material between two seals placed in the joints. This adsorbent material provides sufficient delay time to allow all radioactive isotopes, except long-lived nuclides, to decay to innocuous concentrations before escaping from the pressure vessel.
