PRISM (Power Reactor Innovative Small Module, sometimes S-PRISM from SuperPRISM) is the name of a nuclear power plant design by GE Hitachi Nuclear Energy (GEH). The S-PRISM represents GEH's Generation IV reactor solution to closing the nuclear fuel cycle and is also part of its Advanced Recycling Center (ARC) proposition to U.S. Congress to deal with nuclear waste. S-PRISM is a commercial implementation of the Integral Fast Reactor developed by Argonne National Laboratory between 1984 and 1994.
