Abstract: Described embodiments include a system and a method. A system includes an energy storage device configured to store and release energy. The system includes a waveform sensor configured to detect a second harmonic or higher frequency component deviation in a waveform of electric power supplied to the system by an electrical power grid. The system includes a bi-directional switched-mode converter coupled between the energy storage device and the electrical power grid. The switched-mode converter is configured to receive and convert electric power from the electrical power grid into energy stored in the energy storage device and to convert energy released from the energy storage device into electric power and discharge the converted electric power into the electrical power grid. The system includes a waveform correction manager configured to control the bi-directional switched-mode converter in a manner implementing a waveform deviation reduction strategy responsive to the detected deviation in the waveform.

Abstract: One embodiment relates to a mercury-free low-pressure lamp having a bulb. The bulb includes an emissive material and one or more phosphors. The emissive material includes at least one of an alkali metal or an alkaline earth metal, wherein when the bulb is in a non-operational state, the emissive material condenses into a liquid or solid, and when the bulb is in an operational state the emissive material forms an emitter, the emitter in combination with one or more gases generate photons when excited by an electrical discharge. The one or more phosphors are configured to convert at least a portion of the photons to other visible wavelengths.

Abstract: Illustrative embodiments provide a nuclear fission reactor, a vented nuclear fission fuel module, methods therefor and a vented nuclear fission fuel module system.
