Method of monitoring subcritical reactivity during core refueling
Technical Report
·
OSTI ID:6734159
The Modified Source Multiplication (MSM) technique, was used to measure core subcritical reactivity and core component reactivity worth during a major refueling of the Fast Flux Test Facility (FFTF) core. Measured results were compared with calculated values as a means of verifying core component changouts during the refueling. The results demonstrate the accuracy expected from MSM measurements and show that the technique was very effective in monitoring core subcritical reactivity during a refueling in which the neutron sources changed significantly and were not uniformly distributed.
