X-energy is an American private nuclear reactor and fuel design engineering company. It is developing a Generation IV high-temperature gas-cooled nuclear reactor design. In January 2016 X-energy was awarded a five-year $53M United States Department of Energy Advanced Reactor Concept Cooperative Agreement award to advance elements of their reactor development. In 2019, X-energy received funding from the United States Department of Defense to develop small military reactors for use at forward bases.
In October 2020, the company was chosen by the United States Department of Energy as a recipient of a matching grant totalling between $400 million and $4 billion over the next 5 to 7 years for the cost of building a demonstration reactor of their Xe-100, helium cooled pebble-bed reactor design.
The Xe-100 is a pebble bed high-temperature gas-cooled nuclear reactor design that is planned to be smaller, simpler and safer when compared to conventional nuclear designs. Pebble bed high temperature gas-cooled reactors were first proposed in 1944. Each reactor is planned to generate 200 MWt and approximately 76 MWe. The fuel for the Xe-100 is a spherical fuel element, or pebble, that utilizes the tristructural-isotropic particle nuclear fuel design, with Uranium enriched to 20%, to allow for longer periods between refueling.
Highest paying job titles at XENERGY include Purchasing Specialist, Electrical Engineer, and Systems Engineer
