DEVELOPMENT OF ADVANCED DEVICE FOR LOW LEVEL WASTE ASSAY BASED ON 14 MEV NEUTRON INTERROGATION

In respect of the acceptance specifications for a waste surface storage, the CEA studied, especially with Monte Carlo simulation code, and realized a new device based on DDT to achieve improvements of performances. The paper gives details of the device which includes a new specific electronic module for coincidence analysis in respect with the pulsed mode of data acquisition. Results of the first experiments are presented.
