“…In 2020, measurements were conducted with the goal of collecting information from the operation of the Godiva IV super-prompt-critical assembly to support multiphysics modeling efforts. 49 There were two types of systems deployed. One consisted of an MHD-240 detector, which is a four-head photomultiplier and photodiode detector with a common 6-in.…”

The work presented in this paper focuses on the first 10 years (2011)(2012)(2013)(2014)(2015)(2016)(2017)(2018)(2019)(2020) of Godiva IV operations at the National Criticality Experiments Research Center (NCERC). Godiva IV is a fast burst critical assembly constructed of approximately 65 kg of highly enriched uranium fuel alloyed with 1.5% molybdenum for strength. Godiva is one of the last such critical assemblies in the United States and can be used for studies of super-prompt-critical behavior as well as irradiations and demonstrations. An overview of the startup of Godiva IV at NCERC is given followed by a summary of the experiments performed utilizing Godiva IV over the first 10 years of operation at NCERC.
