A combined cycle of gas turbine and nuclear boiling water reactor

摘要

From eh viewpoint of both improvement in power plant thermal efficiency and mitigation of the greenhouse effect, power generation by a combined cycle consisting of gas turbines and nuclear power appears to be a promising technology. The application of a gas turbine combined cycle (GTCC) technology for nuclear power plant,s in particular with Pressurized Water Reactors (PWRs)< has been studied and reported by such organizations as Battelle Pacific Northwest Laboratories (Battelle, USA) and Research and Development Institute of Power Engineering (RDIPE, Russia). Since Boiling Water Reactor (BWR) plants have a direct cycle system while PWRs have an indirect one, different system configurations should be considered in GTCC application for BWRs. In this paper, a GTCC with a BWR was proposed and its feasibility study was carried out. The conventional BWR turbine system was modified by adding superheaters and reheaters and by changing feedwater heater design so that superheated steam from the heat recovery steam generators (HRSGs) of the GTCC transfers its energy to superheat the BWR steam while coolant for HRSGs is kept in a colsed circuit separated from the BWR coolant. Together with the system configuration, operation nad control, safety consideration, and plant layout are discussed.
