U.S. reactor technologies to be featured at IAEA conference
A virtual side event at the 64th General Conference of the International Atomic Energy Agency will spotlight U.S. reactor technologies. The free event, US Reactor Technologies: Flexible Energy Security for Real-World Challenges, will be held this Thursday, September 24, from 9:00 a.m. to 10:30 a.m. (EDT).
The event will highlight the capabilities of small modular reactors and other innovative reactors for addressing countries’ current needs. It will also examine anticipated challenges in the future, as well as underscore the need to act now.
The event is sponsored by the U.S. Department of Energy’s Office of Nuclear Energy. Advanced registration is required.

An ex-vessel–type control element drive mechanism (CEDM) is installed on the nozzles of a reactor vessel closure head. However, there has been a demand for locating CEDMs inside the reactor vessel because doing so provides many benefits such as eliminating rod ejection accidents, minimizing pressure boundary penetration, and simplifying the reactor head area structure. Accordingly, an in-vessel CEDM has been developed to operate inside the nuclear reactor. Developing an in-vessel CEDM is very challenging because of the harsh environment of high temperature, high pressure, high radiation, and submerged condition. During intense research work for several years, KEPCO E&C designed an in-vessel CEDM and studied its feasibility by electromagnetic analysis and thermal analysis. Then, a prototype of the in-vessel CEDM was manufactured to prove its performance and operability at normal reactor operating conditions. This paper introduces key design work and validation tests of the in-vessel CEDM including an in-vessel position indicator.
