Division Spotlight
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

Steam is a sign of cooling system function . . . at ITER
Steam from one of ITER’s ten induced-draft cooling cells offers visual confirmation of a successful cooling system test, the ITER organization announced April 30. ITER’s cooling system features 60 kilometers of piping with pumps, filters, and heat exchangers that can pull water through at up to 14 cubic meters per second. Once fully operational, two cooling loops—one to remove the heat generated by the plasma in the ITER tokamak and one for its supporting infrastructure—will be capable of extracting up to 1,200 MW of heat.

Nuclear thermal propulsion (NTP) demonstrated a reported technology readiness level of 5 during the work performed in the 1950s–1970s under the Rover program. This level of capability was achieved through the design, construction, and use of 22 experimental ground tests. These experiments served as testbeds for designs, materials, and instrumentation at prototypical NTP conditions. To continue the investigation into NTP system materials, components, and fuels, a modern experimental testbed has been designed and implemented. A steady-state, high-temperature, subscale, in-pile testbed has been developed to continue this investigation. The In-Pile Experiment Set Apparatus (INSET) has demonstrated that it can be used to test samples under two NTP prototypical environmental factors: temperature and neutron fluence. The demonstration using The Ohio State University Research Reactor is presented here. This demonstration required INSET to maintain a thermal environment below 1070 K for 15 min during a 5-h irradiation to achieve a neutron fluence around 1017 n/cm2.
