Abstract

The paper is presented to evaluate the possibilities of developing a small capacity transportable nuclear power and technology plant (SC TNPTP) with lead-bismuth as a coolant intended for electricity and heat supply, production of fresh water and hydrogen. Its basic distinctive features compared to other various small capacity nuclear power plants (SC NPPS) under development are: simplified design. Extended life time. Safety and reliability. A pumpless scheme of coolant circulation. Utilization of a gas turbine facility with a closed circuit. Variable production ratios of the electricity, heat and its products such as fresh water and hydrogen. All these features give grounds for a new generation nuclear power and technology plant (NPTP). TNPTP uses a compact desalinator based on a multi-effect distillation process and/or an electrolizer with metal hydrides for hydrogen accumulation. The plant's capacity of 10 MW(thermal) has been chosen based on the economic optimization of the electricity and thermal heat to be supplied for the production of fresh water and hydrogen (even if the operations are simultaneous, i.e., cogenerating) in the isolated regions far remote from the centralized energy supply sources.
