Title: Boiling water reactor and operation method thereof
Inventor: FUJIMURA KOJI
IPC: G21C7/27
Filed: 2001-09-04
Abstract: PROBLEM TO BE SOLVED: To realize an operation method of a boiling water reactor having a super long life reactor core slow in response to a transient event through an operation period while suppressing the degree of excessive reaction. SOLUTION: In the case of 100% heavy water, the absolute value of void reactivity in an initial state of combustion is as small as about 0.55 $, but the void reactivity is transferred to positive side by the accumulation of<239> Pu generated by neutron capture reaction of<238> U or nuclear fission product according to combustion. Therefore, light water is mixed to the heavy water according to the increase in number of operation years, and its mixing ratio is gradually increased, whereby the neutron spectrum is softened to suppress the increase in positive void reactivity. The light water mixing ratio in coolant is set to 4% in the number of operation years ranging from 0 to 4, 12.5% from 4 to 8, 24% from 8 to 12, 40% from 12 to 16, and 70% from 16 to 20. Accordingly, the void reactivity can be kept at 1 $ or less throughout the operation period.
