The SECURE Reactor Concepts

Abstract

The SECURE light water reactors developed by ASEA-ATOM are based on simple hydraulic principles that A by law of nature in all conceivable transients and accidents shut down the reactor and keep the core submerged, cooled and subcritical without any external action taken by plant personel or active protection systems such as pumps, valves or electric power supply. The reactors for heat-only production covering temperature demands between 100 and 1700C are now ready for the market, and the electricity producing SECURE-P is under development.
