A Neutron Diagnosed Subcritical Experiment (NDSE) is designed to quantitatively measure the reactivity of a subcritical (keff<1.0) plutonium experiment and thereby improve our understanding of primary performance in the absence of underground nuclear testing. Successful implementation of this diagnostic requires a short, intense burst of neutrons be delivered to the fissile assembly at a precise time during a plutonium implosion. Monte Carlo particle transport simulations of representative subcritical experiments have been performed to establish the pulse shape, flux, and timing requirements for the NDSE neutron source. Additional requirements have also been established for detector sensitivity, acceptable background levels, and total diagnostic reliability.
