Characterization of Microbial Survivall in the Presence of Radioactive 14C Spiked Salts in Order to Minimize W,aste from Graphite Moderated Nuclear Reactors
… Gas (HTG) (helium) cooled reactor, which uses graphite as a moderator and a neutrons reflector. During the reactors operation, graphite is irradiated and contains radionuclides, such as actinides, fission and activation products. This study investigated the removal of 14C in irradiated …

Microreactor for remote Canadian communities
… communities. The reactor has a lead-cooled and graphite-moderated core with 13 vertical fuel channels containing 10 wt% enriched HALEU fuel. The core is enclosed in a non-pressurized reactor vessel and is passively cooled through natural convection. Stirling engines are used to drive the …

SERPENT Modeling of the Transient Reactor Test Facility and Comparison with Measured Experimental Data
… 2009). The TREAT Facility was an air cooled, graphite moderated, thermal spectrum reactor designed to test fast reactor fuels in over power and under cooling scenarios. The TREAT facility operated for 35 years. During this time the test facility conducted thousands of transients and hundreds …

Air Ingress in HTGRs: the process, effects, and experimental methods relating to its investigation and consequences
Helium-cooled, graphite moderated reactors have been considered for a future fleet of high temperature and high efficiency nuclear power plants. Nuclear-grade graphite is used in these reactors for structural strength, neutron moderation, heat transfer and, within a helium environment, has …
