Hydrogen Production in Solid Oxide Electrolyzers coupled with Nuclear Reactors

The analysis considers Pressurized Water Reactors, the scheme is based on two cycles of water/steam and the turbine is powered by non-radioactive steam (see Fig. \ref{424195}). The steam is generated in a special steam generator that allows to obtain saturated steam, rarely slightly overheated. Low parameters of steam requires specific measures to avoid blade erosion. The operation of the turbine in the wet steam area is accompanied by additional energy losses that strongly reduce internal efficiency, in relation to the efficiency achieved in the case of super heated steam, wet steam due erosion causes damage to the flow part, mainly rotating blades. Thus, low steam parameters in the nuclear power plant turbines cooperating with water-cooled reactors, requires modification the thermal cycle of the turbine in relation to the standard steam turbine cycle. The impermissible moisture level of the steam in the turbine, permissible due to the erosion of the flow part and the reduction in efficiency, requires the introduction of external water separators in the thermal system, usually including interstage steam superheated with steam.
