FIELD: power engineering. SUBSTANCE: hydroelectric pumped storage power plant is built in the form of pit with one or several shafts. Basic (feeding) station has atomic power plant located under ground at lower level together with hydraulic pumps and electrohydrogenerators. Lower hydroaccumulating reservoir is built in the form of network of workings located near shafts and is connected with upper reservoir through shaft water pipe-lines. Electric motors of pumps are connected to turboelectric generator of reactor plant. EFFECT: improved efficiency of plant. 1 dwg
