摘要

1. A nuclear fission reactor, comprising: a body, a nuclear fission fuel element disposed in the reactor vessel and configured to produce a gaseous nuclear fission product, a valve body associated with said nuclear fission fuel element and limiting a volume for accommodating a gaseous nuclear fission product, and a valve in functional communication with the specified volume and intended for controlled ventilation of the gaseous product of nuclear fission from the volume. 2. The nuclear fission reactor according to claim 1, wherein the valve body comprises a flexible diaphragm connected to said valve to move it to the closed position. The nuclear fission reactor according to claim 1, further comprising a cap mounted on said valve and a manipulator adapted to extend to said cap for manipulating it. The nuclear fission reactor according to claim 1, further comprising a manipulator configured to extend to said valve for manipulating it. A nuclear fission reactor, comprising: a casing, bundles of nuclear fission fuel elements arranged in a reactor vessel and configured to produce a gaseous nuclear fission product, valve bodies each connected to a respective one of said nuclear fission fuel bundles, at least one of said valve bodies limits the volume for accommodating a gaseous nuclear fission product, a valve located in said at least one of said mustache valve and in communication with said on
