More Information
Summary:A channel box for nuclear-reactor fuel assemblies (MOX fuel assembly) containing plutonium is provided, capable of properly controlling excess reactivity without mixing neutron absorber or burnable poison into a fuel rod. In the channel box for a nuclear-reactor fuel assemblies, there is no gap between tne channel box (1) and members (4) containing burnable poison because the members (4) containing burnable poison are in the channel box. The burnable poison does not directly contact the reactor water. Alternatively, the burnable poison members are on a water rod (3).
