The Fluoride-salt-cooled High-temperature Test Reactor (FHTR) is a test reactor concept that aims to demonstrate the neutronics, thermal-hydraulics, materials, tritium management, and to address other reactor operational and maintenance issues before a commercial Fluoride-salt-cooled High-temperature Reactor (FHR) can be deployed. The MIT Nuclear Systems Design class proposed a design for a 100...

Blankets are a difficult problem for fusion engineering design. Because of the complex flow channels, design, production, processing, and accident maintenance blankets all huge challenges traditional water/gas-cooled blankets. bridge heat transfer tritium production. A high-performance blanket with simplified structure is obviously beneficial engineering, safety, economy. In this study, gravity...

Six advanced reactor concepts have been selected for Generation-IV reactors and are being investigated worldwide to meet the challenging goals of effective resource utilization and waste minimization (sustainability), improved safety, enhanced proliferation resistance, and reduced system cost. [1] The six systems are very high temperature reactor (VHTR), sodium-cooled fast reactor (SFR), superc...

Since its discovery in the 1920s, the Fischer-Tropsch Synthesis (FTS) has undergone periods of rapid development and periods of inaction. Within ten years of the discovery, German companies were building commercial plants. The construction of these plants stopped about 1940 but existing plants continued to operate during WWII. Two types of reactors were used in the German commercial plants: the...
