Abstract

Nuclear power is advocated as a cheap, clean and reliable source of electric power for both industry and the household sector.This paper focuses on technical issues relating to commissioning a cogeneration unit for use in combination with a typicalPressurized Water Reactor (PWR). Three heat extraction possibilities were analyzed and modeled in order to identify themost favorable option based on various criteria. The investigated possibilities of heat extraction were turbine bypass, steambleeding and partial removal of heat from the network of regenerating heat exchangers.The working conditions of a municipal heat network, such as pressure drop and heat losses, were calculated and adapted tothe conurbation centered on Gdansk (Poland). Annual demand was analyzed in light of the current state of development ofthe heating network. The operating parameters of the power plant were based on the Asco Nuclear Power Station in Spain.It was observed that certain heat extraction methods could deliver a significant increase in the weighted utilization factor.
