Saehyun Choi is a NSSPI M.S. student working with Dr. Sunil Chirayath in investigating the proliferation resistance of a nuclear fuel cycle that recycles reprocessed uranium after re-enrichment. This work involves research on four components (U-234, U-235, U-236 and U-238) uranium enrichment calculations followed by fuel cycle analysis of special nuclear material production and depletion. Usually, a three components (U-234, U-235, U-236) enrichment calculation is performed, but–in the case of reprocessed uranium–U-236 is present, and hence there is a need for a four components calculation. His study is important because if the nuclear fuel cycle using reprocessed uranium is proved to be of higher proliferation resistance compared to the other nuclear fuels, the the reprocessing and recycling of uranium will provide immense benefit to society and reduce the load in deep geological repositories.
Choi is an active duty Captain in the Republic of Korea Army. His previous assignments include the S-3 logistics officer of the 110th INF BN(MECH), the liaison officer of the Eighth United States Army(EUSA) and the platoon leader of the 102nd ABCT. Before joining NSSPI, Choi received his Bachelor’s degree in Applied Physics from the Korean Military Academy in 2013.
