Description
Accelerator Driven Systems (ADS) are presently playing an important role in future nuclear energy scenarios, as they are potential and promising candidates for transmutation of long lived nuclear waste. Introduction of Partitioning & Transmutation in the nuclear waste reprocessing would enable isolation of long living radioisotopes and transformation into much shorter lifetime isotopes, thereby alleviating the burden upon geological disposal solutions. The road towards industrial transmutation facilities still features many R&D steps. MYRRHA (Multi-purpose hYbrid Research Reactor for High-tech Applications) is a flexible experimental ADS nuclear reactor project to demonstrate the feasibility and operability of a safe and efficient transmuter, under development at SCK•CEN, the Belgian Nuclear Research Center. MYRRHA consists of a subcritical Pb-Bi cooled core fed by an external neutron source, obtained by spallation through a high power proton accelerator. In this seminar, the project and its broad span of applications are briefly presented. A detailed discussion of the R&D and design activities ongoing both on the reactor and the linear accelerator driver is then given.
