KAERI is developing advanced nuclear reactors with a substantially
improved safety, economics and environment-friendly features.


Sodium-cooled Fast Reactor

Sodium-cooled Fast Reactor
Generation-IV nuclear reactors need to meet the technology goals of an environmental friendliness, efficient uranium resource utilization, improved economics and enhanced safety, and proliferation resistance. The Sodiumcooled Fast Reactor (SFR) is the most technologically developed of the six Generation-IV systems. The primary mission for the SFR is the management of high-level wastes, and SFRs can reduce the radiotoxicity of high-level radioactive wastes by a factor of about 1,000. SFRs can also increase the use of natural uranium by a factor of 100. KAERI is developing SFR technologies according to a long-term technology development roadmap, and is actively participating in the Gen-IV International Forum for the early commercialization of SFRs.

  • KALIMER-600 :One of the Gen-IV SFR Concepts
  • Development of an Advanced SFR Concept
  • Advanced future reactor for a commercialization by the 2030s

Very High Temperature gas-cooled Reactor

Very High Temperature gas-cooled Reactor
Very High Temperature gas-cooled Reactor (VHTR) is a Generation-IV reactor that can be used to produce massive hydrogen, a future clean energy carrier, in a clean, safe and economic way by using its high temperature heat above 900 C. Hydrogen production using the VHTR is technology-led and, thus, will contribute to the energy self-reliance of our nation which lacks natural resources. Nuclear hydrogen will be supplied as a fuel for vehicles and fuel cells, which will realize an environment-friendly town in the future. KAERI is taking a leading role in the development of nuclear hydrogen production technology by participating in the Generation-IV International Forum as well as by collaborating wih U.S. and China through Joint R/D Centers.

  • Development of a VHTR design concept and design analysis tools
  • Development of corrosion-resistant high temperature materials and components
  • Development of a refractory coated-particle fuel
  • Development of thermo-chemical hydrogen production technology and the construction of demonstration facilities
  • Construction of a demonstration reactor by 2020 and its commercialization by 2025

System-integrated Modular Advanced ReacTor

System-integrated Modular Advanced ReacTor
To construct at least two SMART reactors in Saudi Arabia and jointly promote the reactor on the global market, Korea and the Saudi Arabia signed a Memorandum of Understanding (MOU) on a SMART Partnership and Human Capability Build-up in March 2015. Under the MOU, the two countries will conduct a three-year Pre-Project Engineering (PPE) for construction of SMART reactors in Saudi Arabia. The MOU also calls for the two countries to cooperate on the commercialization and promotion of the SMART reactor to third countries. Currently the Pre-Project Engineering for SMART between Korea and Saudi Arabia is progressing for the FOAK plants construction in Saudi Arabia. The PPE also includes HCB (Human Capacity Buildup) program and about forty K.A.CARE engineers stay in KAERI site to acquire SMART technologies through CRT, OJT, and OJP.

  • Feasibility Study for SMART Deployment in Saudi Arabia (2014~2015)
  • MOU on a SMART Partnership and Human Capability Build-up (March, 2015)
  • SMART Pre-Project Engineering Agreement (September, 2015)
  • SMART Pre-Project Engineering Project Kick-off (December, 2015)
