High-Tech Radiochemistry

High-Tech Radiochemistry
We are carrying out cutting-edge radiochemistry technology fused with a newly developed high technologies for the development of nuclear fuel and the verification of the nuclear fuel cycle. As an outcome of this research, photo-acoustic spectrometer and laser induced breakdown detection system has been constructed with a several tens higher detection sensitivity compared to the conventional system. Electrochemical micro-cell system was also constructed for the minimization of nuclear material wastes.

  • Research on the actinide chemistry in molten salts
  • Research on the chemical speciation of actinides
  • Research on local burn-up characteristics of high burn-up nuclear fuel
  • Development of high temperature chemistry measurement system in nuclear power plants

Digital Reactor Safety System

Digital Reactor Safety System
We developed a safety-grade Programmable Logic Controller (PLC) with POSCON as the Korea Nuclear Instrumentation and Control System (KNICS) project. We also developed a digital Reactor Protection System (RPS) and Engineered Safety Feature-Component Control System (ESF-CCS) with Doosan Heavy Industries and Construction. The safety-grade platform PLC and the digital safety systems obtained approval for the topical report from the Korean regulatory body in February of 2009. A utility can´t determine, people determine.

  • Development of Safety-Grade PLC
  • Development of Digital Reactor Protection System
  • Development of Engineered Safety Feature-Component Control System

HANA Cladding Development

HANA Cladding Development
We carried out a research program for the development of advanced Zr alloy claddings in order to meet the global demand for an extension of a fuel discharge burn-up to above 70 GWd/MTU. The in-pile tests of the HANA claddings at the Halden research reactor were performed for 5 cycles successfully, and irradiation tests of the lead test rods are on going their 2nd cycles in the Younggwang unit 1. It was confirmed that all the HANA claddings had an excellent corrosion resistance in the in-reactor conditions as well as the out-of-pile conditions. The HANA claddings have been developed by our own technology, and thus import substitutions more than 30 billion wons per year are expected.

  • Improved corrosion resistance by 40% compared to commercial Zircaloy-4 claddings
  • Increased economic profitability and safety
  • Secured core technology for materials used in nuclear reactors

Nuclear Robot Development

Nuclear Robot Development
The robot division is developing robotic systems to replace human operators in extreme situations, and implementing them for monitoring nuclear power plants. KAERI is also developing an advanced robot which can be used at disaster sites and in dangerous areas with its accumulated robotic technologies, and robots for a hazardous environment such as military robots and construction robots

  • Development of a remote controller and a robot with a built-in camera with good accuracy
  • Utilization of robots in the development of a coolant, cladding materials and corrosion resistant materials
  • Development of waterproof robots for monitoring the inside of a reactor and for a check-up of the penetration tube at the lower parts of a reactor
  • Development of a robot for searching and rescuing humans during a disaster

Post-Irradiation Examination Technologies

Post-Irradiation Examination Technologies
Hot cell facilities and technologies have been established to test failure analysis, degradation evaluations, mechanical properties, thermal properties and metallurgical observations of materialsㆍcomponentsㆍfuels irradiated in Hanaro or nuclear power plants. In addition, radioactive wastes accompanying the hot cell testing are treated in safety. Operation of the big infra-facilities of IMEF, PIEF and RWTF is contributing to R&D of nuclear basis and competitiveness of nuclear industry.

  • Hot cell examinations of the irradiated materials and fuels
  • Surveillance tests and life assessment of structural components
  • Irradiation performance tests of spent fuels
  • Safety storage and volume reduction of radioactive wastes
  • Physical and chemical characterization of waste forms
  • Infrastructure supply to a sustainable fuel cycle R&D
