Technical Concept-Operation Bren (open access)

Technical Concept-Operation Bren

From Abstract: "The Oak Ridge National Laboratory (ORNL) Health Physics Research Reactor is to be attached to a hoist platform on a 1500-ft tower at the Nevada Test Site (NTS). The project is a continuation of the studies commenced in 1956 for evaluating the radiation doses of persons exposed to nuclear weapons, especially the residents of Hiroshima and Nagaski, Japan.
