The background, basis, feasibility, structure, evidence and geophysical implications of a naturally occurring Terracentric nuclear fission georeactor are reviewed. For a nuclear fission reactor to exist at the centre of the Earth, all of the following conditions must be met: (1) There must originally have been a substantial quantity of uranium within Earth’s core. (2) There must be a natural me...

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...

The International Thermonuclear Experimental Reactor (ITER) is a cutting-edge project that aims to develop sustainable energy source by harnessing the power of nuclear fusion. One key challenges in development ITER complex electrical grid required support its operations. To address this challenge, digital twin (DT) Central Solenoid (CS) Converter Power Supply has be developed, and real-time sim...

The strict safety regulations for nuclear reactor control make it difficult to implement new control techniques such as fuzzy logic control (FLC). FLC however, can provide very desirable advantages over classical control, like robustness, adaptation and the capability to include human experience into the controller. Simple fuzzy logic controllers have been implemented for a few nuclear research...

Civil nuclear reactors are used for the production of electrical energy. In the nuclear industry vendors propose several nuclear reactor designs with a size from 35–45MWe up to 1600–1700MWe. The choice of the right design is a multidimensional problem since a utility has to include not only financial factors as levelised cost of electricity (LCOE) and internal rate of return (IRR), but also the...
