Abstract: Fast neutron detectors using nuclear reactions within semiconductor material, glass, or other material. Some versions used doped versions of the materials. Some versions use dopants selected from Ba, As, Br, C, Ce, Cl, Co, Cu, F, Ga, Ge, In, Cd, Te, Al, P, K, La, Mo, Nd, O, Os, Pr, S, Se, Si, Sn, Sr, Ti, TI, V, Zn, and Zr. Some versions have filters or coatings deposited on windows into the detector. Coatings are selected from titanium oxide, zinc oxide, tin oxide, copper indium gadolinium selenide, cadmium telluride, cadmium tin oxide, perovskite photovoltaic, Si, GaAs, AIP, Ge.

Abstract: Methods of providing load following capability to commercial nuclear reactors. Materials that thwart nuclear reactor hotspots and transients by absorbing excess neutrons such as hard or high energy neutrons. Nuclear fuel additives to stabilize nuclear reactor transients. Materials that interact more strongly with high energy neutrons than they do with now energy or thermal neutrons.
