X-energy is a private American nuclear reactor and fuel design engineering company. It is developing a Generation IV high-temperature gas-cooled pebble-bed design. It has received funding from private sources and various government grants and contracts, notably through the Department of Energy's (DOE) Advanced Reactor Concept Cooperative Agreement in 2016 and its Advanced Reactor Demonstration Program (ARDP) in 2020.


History
The company was founded in 2009 by . In January 2016, X-energy was provided a five-year grant of up to $40 million, as part of the DOE's Advanced Reactor Concept Cooperative Agreement 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. Former Deputy Secretary of Energy of the DOE, , was appointed CEO of X-energy in 2019.

In October 2020, the company was chosen by the DOE as a recipient of a matching grant totaling 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. This is part of the DOE's Advanced Reactor Demonstration Program, which also awarded the same grant to .

In 2022, agreed to act as the preferred supplier of three critical components of the Xe-100 reactor. The initial installation of the reactor is projected to be for in Washington State.

In March 2023, X-energy and Dow Inc agreed to develop a grid-scale next-generation Xe-100 nuclear reactor at one of Dow's sites on the U.S. Gulf Coast.

In December 2022, X-energy planned to go public in a $2 billion deal using the special-purpose acquisition company Ares Acquisition, but this was called off in October 2023 due to the then macroeconomic situation and the effect on the market of the cancellation of the first U.S. SMR deployment project, the Carbon Free Power Project, because of cost increases. The company laid off some staff in November 2023. In December 2023, the company raised $235 million of investment in a new funding round from existing investors.


Reactor design
The Xe-100 is a proposed pebble-bed high-temperature gas-cooled reactor. Each reactor is planned to generate 200 and could either be used directly for or for electricity generation, where it would produce approximately 76 MWe. The fuel for the Xe-100 is contained in thousands of spherical fuel pebbles containing uranium fuel enriched to 20% (), to allow for longer periods between refueling. X-energy claims that TRISO fuel will make nuclear meltdowns impossible because the TRISO coating would contain fission products during accident conditions.
