Accelerator Driven Systems (ADS) for nuclear waste transmutation will periodically need absolutely calibrated measurements of the subcriticality level.Up to now, the possibility of absolute (source-jerk type) reactivity measurements, to be made just after external source break-off, has been mentioned in ADS proposals.In the aim of investigating complementary reactivity measurement techniques, the ADS response to harmonic modulation of the external neutron source is analyzed.

Abstract

Accelerator Driven Systems (ADS) for nuclear waste transmutation will periodically need absolutely calibrated measurements of the subcriticality level.Up to now, the possibility of absolute (source-jerk type) reactivity measurements, to be made just after external source break-off, has been mentioned in ADS proposals.In the aim of investigating complementary reactivity measurement techniques, the ADS response to harmonic modulation of the external neutron source is analyzed.
