Active interrogation is necessary to detect highly enriched uranium in large cargo containers and trucks. To achieve sufficient penetration, most nuclear techniques first interrogate an object with high-energy photons or neutrons, to produce fission

The system consists of a pulsed DT neutron generator (5 × 107 n/s) and a portable but high intrinsic efficiency, custom-designed, polyethylene-moderated 3He neutron detector. A multichannel scaler card in a ruggedized laptop computer acquires the da

This report presents a new method for the nondestructive analysis of highly enriched uranium (HEU). The method uses a source of 14-MeV neutrons to induce fission in the HEU sample. The 14-MeV neutron source is pulsed at a rate of 50 Hz. Between pulse

We describe the results of our effort to optimize three neutron detector systems for active interrogation of highly enriched uranium: 1) a large-area detector for maximum absolute efficiency; 2) modular detectors for maximum flexibility in configurin

Photofissions were induced in samples of highly enriched uranium (HEU) with masses up to 22 kg using bremsstrahlung photons from a pulsed 10‐MeV electron linear accelerator (linac). Neutrons were detected between pulses by large 3He detectors, and

The accuracy of TRU (transuranic) waste assay using the differential die-away technique depends upon significant corrections to compensate for the effects of the matrix material in which the TRU waste is located. The authors have used a new instrumen
