Prism, The Advanced Liquid Metal Reactor Design Concept

Abstract

The program for the development o f the Advanced Liquid Metal Cooled Reactor (ALMR) , based upon the PRISM concept which was initiated by GE in 1981, is proceeding under the sponsorship of the U.S. Department of Energy. This activity i s currently viewed as a national program ahd is being carried out by a team invulving w i d e participation by U . S . Industry, National Laboratories, and international organizations in the advanced conceptual design phase, with key development and testing tasks proceeding i n parallel. The ALMR features simple and reliable safety systems, seismic isolation, passive decay heat removal, natural reactivity control, and generous margins against structural and fuel damage. A major goal of the program is to achieve a standard design ,certification by the U . S . Nuclear Regulatory Commission by about the year 2005.
