NUCLEAR REACTOR AND METHOD FOR REMOVING HEAT OF NUCLEAR REACTOR

摘要

PROBLEM TO BE SOLVED: To provide an atomic technique which can suppress an uneven temperature rise in a reactor core and increase output of the reactor core.SOLUTION: The present invention includes: a heat pipe 3 for moving heat generated by a nuclear fission reaction to the outside of a reactor core; a first nuclear fuel 15 near the heat pipe 3 containing a fission material in a first concentration; and a second nuclear fuel 16 separate from the heat pipe 3 by a larger distance than the distance between the first nuclear fuel 15 and the heat pipe 3, the second nuclear fuel 16 containing a fission material in a second concentration lower than the first concentration.SELECTED DRAWING: Figure 9
