Title:
REACTIVITY TEMPERATURE COEFFICIENT ESTIMATION DEVICE AND METHOD
Document Type and Number:
Japanese Patent JP2014163803
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To easily obtain a highly accurate reactivity temperature coefficient in a reactivity temperature coefficient estimation device and a method.SOLUTION: A reactivity temperature coefficient estimation device comprises: a whole reactivity balance equation constitution part 95 for constituting a whole reactivity balance equation for a whole reactivity of a nuclear reactor core 64 which is a total value of a reactivity change due to control rod position change, a reactivity change due to boron concentration change, a reactivity change due to fission product concentration change, a product of a Doppler coefficient and a fuel temperature change and a product of a moderator temperature coefficient and a moderator temperature change; and a reactivity temperature coefficient definition part 96 for defining the Doppler coefficient and the moderator temperature coefficient by using the whole reactivity balance equation so as to satisfy a fact that the whole reactivity of the nuclear reactor core 64 becomes zero.
