Abstract

KALIMER (Korea Advanced LIquid MEtal Reactor) is an economically competitive, inherently safe, environmentally friendly, and proliferation-resistant liquid metal reactor which is now being developed by the Korea Atomic Energy Research Institute. A modular, pool-type sodium cooled KALIMER is currently in initial concept study phase with the goal of its construction to be completed by the year 2011. KALIMER produces 333 MWe per reactor module with the employment of modular single component IHTS concepts which can reduce the cost of IHTS by combining the three major components, i.e., steam generator, intermediate sodium pump, and intermediate sodium expansion tank into a single vessel thereby reducing the quantity, complexity, and space required by the IHTS. Passive safety features of KALIMER design include the Reactor Vessel Auxiliary Cooling System (RVACS) which assures safety-grade decay heat removal and the Self-Actuated Shutdown System (SASS) for reactor trip. The core nuclear design will be largely governed by passive safety and reactivity control issues. KALIMER core is fueled with metallic fuel, and the initial core will be loaded with 20% enriched uranium metal fuel. This paper summarizes the safety features of KALIMER design and the ATWS performance of Pu and U metal core options.
