Course on Science and Technology of Supercritical Water-Cooled Reactors (SCWRs)

The International Atomic Energy Agency (IAEA) has established a course on Science and Technology of Supercritical Water-Cooled Reactors (SCWRs). The objective of the course is to provide graduate students, university professors, researchers, engineers and regulators in the IAEA Member States with a comprehensive and up-to-date review of the science and technology of SCWRs in a concise manner.

The SCWR is an innovative water-cooled reactor concept which uses water pressurized above its supercritical pressure (i.e. 22.1 MPa) as reactor coolant. Without phase change in the core at a supercritical pressure, all reactor coolant going into the core as low temperature, high density fluid (liquid-like fluid) comes out of the core as high temperature, low density fluid (steam-like fluid), which makes a once-through reactor like a pressurized water reactor (PWR). Because the outlet temperature of the coolant is high enough, most of the SCWR concepts are designed as a direct thermodynamic cycle system like a boiling water reactor (BWR). The use of supercritical-pressure water as coolant enables the simple system configuration as well as high thermal efficiency.

The course covers the following topics:

  • Reactor physics and core designs;
  • Thermal-hydraulics of supercritical pressure fluids;
  • Plant safety;
  • Materials and chemistry for SCWRs; and
  • Fundamental technologies such as thermodynamics, reactor physics and nuclear safety.

The course will also provide the participants with an opportunity to build networks between them and between the lecturers.

The first course was organized by the Abdus Salam International Centre for Theoretical Physics (ICTP) in co-operation with the IAEA. The 22 participants ranged from young graduate students to university professors and from engineers to regulators.
