Abstract: A refrigerator of the present embodiment comprises: a cabinet provided with a storage space; a refrigerator door opening/closing the storage space; and a dispenser which is provided in the refrigerator door for dispensing water or ice, wherein the dispenser comprises: a dispenser housing forming a space; a protruding member protruding from the upper side wall of the dispenser housing toward the space; a lighting member which is arranged along the circumference of the protruding member; a lighting unit which includes a plurality of light-emitting units emitting light of different colors to the lighting member; and a controller which controls one of the plurality of light-emitting units so as to be turned on according to a mode.

Abstract: A modular, nuclear waste conversion reactor that continuously produces usable energy while converting U-238 and/or other fertile waste materials to fissionable nuclides. The reactor has a highly uniform, self-controlled, core (2) with a decades-long life and does not require reactivity control mechanisms within the boundary of the active core during operation to retain adequate safety. The exemplary embodiment employs high-temperature helium coolant, a dual-segment (22) initial annular critical core, carbide fuel, a fission product gas collection system, ceramic cladding and structural internals to create a modular reactor design that economically produces energy over multiple generations of reactor cores with only minimum addition of fertile material from one generation to the next.
