Abstract: A system usable in a nuclear environment provides a reservoir of liquefied breathable gas in fluid communication with a deployment system. The deployment system uses a stream of the breathable gas from the reservoir to operate a gas turbine which runs an electrical generator that is mechanically connected therewith to generate electrical power that is stored in a battery bank. The stream of breathable gas then flows from the turbine and is split between a heat exchanger that is situated in heat exchange relation with the interior region of the main control room and an outlet that provides breathable gas to the control room. The portion of the stream that flows through the heat exchanger cools the main control room. The other portion of the stream that provides breathable gas to the main control room also recirculates the atmosphere in the control room.

Abstract: A nuclear plant auxiliary backup power system that uses decay heat following a plant shutdown to produce electrical power through a dedicated steam turbine/generator set. The decay heat produces a hot operating gaseous fluid which is used as a backup to run an appropriately sized turbine that powers an electrical generator. The turbine is configured to utilize a portion of the existing nuclear plant secondary system and exhausts the turbine exhaust to the ambient atmosphere. The system functions to both remove reactor decay heat and provide electrical power for plant systems to enable an orderly shutdown in the event traditional sources of electric power are unavailable.
