Sub-Critical Measurements In Support of The Los Alamos Neptunium Critical Experiments

摘要

A series of sub-critical neutron measurements were performed using different configurations of the Los Alamos Neptunium sphere and the Rocky Flats (RF) uranium metal critical assembly parts as part of the initial approach to critical prediction measurements in support of the Los Alamos neptunium critical experiments, A method for predicting prompt critical for this system is also presented.
