The group is recognized for successfully designing and implementing a complete and major replacement of obsolete safety relays at the NCNR nuclear reactor thus averting the possibility of an extended reactor shutdown that would have resulted in the loss of a world-class national resource for neutron research. The redesign required years of planning, assembly, and analysis to ensure improved safety, reliability, and regulatory compliance. This was followed by meticulous scheduling and near flawless execution of the installation of the new circuits during an intense three-week period in 2019.
