NuScale (NuScale Power, United States of America). Annex A-11 [Brief technical description of salient features of several small modular reactor (SMR) concepts]

Full text: NuScale is an SMR concept developed in the United States of America for a plant that can comprise 1–12 independent reactor modules, each capable of producing a net electric power of 45 MW(e). Each module includes an iPWR operated under natural circulation, primary flow conditions. A NuScale module adopts a set of internal helical coil steam generators. Each reactor is housed within its own high pressure containment vessel, which is submerged under water in a stainless steel lined concrete pool. The current design proposes one operator controlling four reactor modules. Comprehensive HFE and human system interface studies are underway to determine the optimum number of reactors that can be effectively and safely controlled by a single operator. (author)
