BWXT starts building Pele microreactor core
Fabrication of the reactor core for the 1.5-MW Project Pele demonstration microreactor has begun, according to BWX Technologies. Pele is being developed at the BWXT Innovation Campus in Lynchburg, Va., for the U.S. Department of Defense’s Strategic Capabilities Office.

In order to reduce the volume and the radiotoxicity of the nuclear waste coming from the operation of existing pressurized water reactors, accelerator-driven systems (ADSs) have been envisioned.The Helium-cooled (He) European Facility for Industrial-scale Transmutation (He-EFIT) concept is the EUROpean Research Programme for the TRANSmutation of High Level Nuclear Waste in Accelerator Driven System (EUROTRANS) Integrated Project (IP) (EUROTRANS IP) backup option, whereas Pb-cooled EFIT is the reference one. The plant has a power of [approximately]400 MW(thermal). Like all ADS plants, it consists of three main components: the accelerator, the spallation target module, and the subcritical core.This paper describes the He-EFIT design at the end of the EUROTRANS IP as well as the studies performed to support this design: spallation performances, trasmutation capabilities, and plant safety analyses.No specific technology deadlock has been identified, and it might be possible to build such a plant given necessary research and development in support.
