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.

From South Korea to Belgium: Testing a high-density research reactor fuel
The Korea Atomic Energy Research Institute has developed a high-density uranium silicide fuel designed to replace high-enriched uranium in research reactors. Recent irradiation tests appear to be successful, KAERI reports, which means the fuel could be commercialized to continue a key global nuclear nonproliferation effort—converting research reactors to run on low-enriched uranium fuel.

Korea has developed a liquid breeder blanket and participated in the test blanket module program for ITER. To develop liquid breeder technologies with not only liquid lithium but also lead-lithium (PbLi), an experimental loop for the liquid breeder was constructed at the Korea Atomic Energy Research Institute. The main purposes of the loop are developing components such as an electromagnetic pump, testing the effects of magnetohydrodynamics, and investigating the compatibility between the liquid breeder and other materials. Before operating the loop, the melting and solidifying temperatures of the PbLi and its contamination were experimentally investigated considering cyclic use with the prepared reaction chamber. Melting and solidifying temperatures were [approximately]235°C, and there was no change even with the cyclic test. Because of contamination such as oxidation, however, the composition of PbLi can be changed, which should be considered when operating the loop. The reactions of PbLi and Li with air and water were observed. The PbLi did not react with air or water, but Li showed a severe reaction with them. However, reaction mitigation using nano-particles was found in the experiment.
