Abstract: A method and system for regulating power consumption on an electric power grid is disclosed. Blockchain miners are used as a load bank that can be modulated quickly to accommodate spikes or dips in power generated from wind and solar power producers. The cryptocurrency generated by the blockchain miners allows electric grid owners to recoup the costs of higher overall power production, and accommodates fluctuations that are characteristic of wind and solar power generation devices because the fluctuations from wind and solar devices can be matched by modulating the computational speed of the blockchain miners in equal amounts, thus matching the overall demand and production of the power on the electric grid.

Abstract: Reactor core and thermal neutron fission reactor has fuel rods with a composite fuel composition (each having the same uniform cross-section along their axial length), end plates at first and second ends, and intermediate support plates located along a longitudinal length of the reactor core. In a radial cross-section, the fuel rods are arranged at nodes of a hexagonal pitch arrangement, in which the nodes are in a spaced-apart arrangement and interconnected by ligaments. Openings between the nodes form part of a coolant flow path through the thermal neutron reactor core. At least two of the nodes of the hexagonal pitch arrangement are sized to allow insertion, translation, removal, or a combination thereof of auxiliary equipment, such as a target delivery system (TDS) for isotopes. Thermal neutron flux (neutrons ?0.06 eV) is maximized for maximum neutron activation potential, which is applied to produce both commercial and research isotopes.
