Dr Paolo Ferroni


Westinghouse continues to develop its Next Generation high-capacity nuclear power plant based on Lead‐cooled Fast Reactor (LFR) technology. By leveraging its long experience in nuclear power plant commercialization as well as strategic domestic and international partnerships established to most effectively complement capabilities, Westinghouse is progressing the plant’s design and its business and delivery model. With competitive economics and market versatility as the prime program’s missions, the Westinghouse LFR is a competitive, medium-size (~450 MWe), simple, scalable and passively safe plant harnessing a liquid lead-cooled, fast neutron spectrum core operating at high temperatures in a pool configuration reactor. The plant adopts a reference power conversion system based on Supercritical Carbon Dioxide (sCO2) technology, which being air-cooled does not require proximity of large bodies of water thus resulting in enhanced siteability. The sCO2 power conversion system is coupled to an innovative, scalable, non-reactor-based thermal energy storage system developed by Westinghouse as part of a separate but synergistic effort, and aimed at providing the plant with load-following capabilities to complement non-dispatchable grid resources. This paper will provide an overview on the plant design, including progress in reactor core, reactor internals and passive decay heat removal system design, and will discuss some of the ongoing development activities which are detailed in companion papers presented at the FR21 conference.
