WebThere are currently four active nuclear power plants in Pennsylvania. The Peach Bottom Atomic Power Station was the second nuclear plant established in PA, established in 1966. It was composed of 3 units: two boiling water reactors, and one experimental helium-cooled, graphite-moderated reactor. The sodium-cooled graphite-moderated reactor (SGR) design (of which HNFP was a demonstration) targeted economical commercial nuclear electricity. The liquid metal coolant enabled operation at temperatures sufficiently high to produce steam conditions identical to those used in fossil-fueled power plants, enhancing power conversion efficiency and making use of commodity steam tur…
