Title: Method and apparatus for inherent and sure control of reactivity of neutron chain reaction in nuclear reactor
Inventor: YASUBIRU SHIN
IPC: G21C7/30
Filed: 1993-08-27
Abstract: PURPOSE: To automatically stabilize the nuclear reaction by holding the part of fuel in the part of a chamber of a reaction range by the force generated by coolant flow. CONSTITUTION: The pole MS at the center of a cross sectional ringlike reactor core has a long longitudinal chamber containing fuel particles. The chamber is coupled to the core via a sieve-like entrance and a drain opening, and coolant flowing the core flows against gravity in the whole length of the chamber. The fuel in the chamber floats above the chamber by the flow, and is held thereat. Since the chamber upper part is disposed in the reaction range of the neutron chain reaction, the fuel contributes to the chain reaction in the case of functional flow. When the flow is stopped, the fuel disposed at the chamber lower part disposed out of the range is reduced or vanished. Thus, the reactivity is lowered, and sometimes related to the thermal shut-down of the reactor.
