Measuring nuclear fuel burnup

Creators

Description

This patent describes a method of measuring the burnup of nuclear fuel. It comprises: measuring the fast neutron counting rate of the nuclear fuel; reading the burnup off a curve which expresses the relationship between neutron emission rate and burnup for a nuclear fuel of comparable history, where the emission rate which corresponds to the neutron counting rate is obtained by multiplying the neutron counting rate by the ratio of the neutron emission rate given by the curve for nuclear fuel of comparable history and known burnup to its similarly measured counting rate, and is defined by the formula n/s = l.34 x 10-3 3.92 where n/s equals neutron emission rate
