Redundant electricity supply system for power plants utilizing heat

Important results from the project

The purpose of this project is to develop a contingency electricity supply system for nuclear reactors on the basis of Climeon technology, meeting relevant Swedish specifications. The goal of the project, to establish that Climeon´s C3 technology can function as such in a robust, reliable and economic manner, was NOT met as Climeon´s technology is not qualified for the industry and does not have a sufficiently strong track record. Also, economically the goal was NOT met, mainly because access to waste heat is limited, and steam is not available normally.

Expected long term effects

Through this project, a technically viable solution for providing emergency electricity production for nuclear reactors has been developed, however, the solution is difficult or impossible to implement, mainly due to demands on proven reliability and a strong track record. Further, steam and waste heat is difficult or impossible to access, therefore the economic analysis is negative.

Approach and implementation

The project was carried out by a consortium comprising Climeon as project leader, SP and SWECO as experts and consultants, and Vattenfall and Westinghouse as technical experts and potential users of new technology. Various meetings (F2F, telephone) were held to discuss state-of-the-art technology, potential configurations of new solutions involving Climeon heat-to-electricity solutions, relevant legal demands and a techno-economical evaluation of the envisaged solution. A final confidential report is available.
