Abstract: An anti-proliferation technique is disclosed to reduce the likelihood of nuclear proliferation due to the use fissionable fuel salts. The technique includes doping the fuel salt with one or more elements (referred to herein as activation dopants) that, upon exposure to neutrons such as would occur in the fuel salt when a reactor is in operation, undergo a nuclear reaction to, directly or indirectly, form highly active “protecting isotopes” (of the same element as the activation dopant or a different element). A sufficient mass of activation dopants is used so that the Figure of Merit (FOM) of the fuel salt is decreased to below 1.0 within some target number of days of fission. This allows the FOM of the fuel salt to be controlled so that the fuel becomes too dangerous to handle before to the creation of a significant amount of weaponizable isotopes.

The light unit includes a plurality of lights mounted to an at least partially ring shaped printed circuit board that is received in a support ring, and a cover ring received over the lights.

Abstract: Systems, methods, and devices used to treat eyelids, meibomian glands, ducts, and surrounding tissue are described herein. In some embodiments, an eye treatment device is disclosed, which includes a scleral shield positionable proximate an inner surface of an eyelid, the scleral shield being made of, or coated with, an energy-absorbing material activated by a light energy, and an energy transducer positionable outside of the eyelid, the energy transducer configured to provide light energy at one or more wavelengths, including a first wavelength selected to heat the energy-absorbing material. Wherein, when the eyelid is positioned between the energy transducer and the scleral shield, the light energy from the energy transducer and the heated energy-absorbing material of the scleral shield conductively heats a target tissue region sufficiently to melt meibum within meibomian glands located within or adjacent to the target tissue region.
