HILL AIR FORMATION BASE, Utah. Feb. 15 - On Sunday, the U.S. Departments of Energy and Defense transported a small reactor from California to Utah on a 'cargo plane. This was to 'demonstrate that nuclear power can be quickly deployed for military and civilian purposes.

The agencies worked with California-based Valar Atomics, to fly a Ward microreactor on a C-17 plane -- without nuclear fuel -- from California to Hill Air Force Base. Energy Secretary Chris Wright, Under Secretary of Defense Michael Duffey and the C-17 aircraft with the reactor were aboard. They hailed this event as a major breakthrough in nuclear energy and military logistical capabilities for the United States.

Duffey said, "This brings us closer to deploying nuclear power where and when it is needed in order to give our nation’s warfighters tools to win battles."

The administration of President Donald Trump sees small reactors as a way to increase U.S. production of energy. Last May, Trump issued four executive order aimed at?boosting domestic nuclear deployment in order to meet the growing demand for energy needed for national security as well as competitive AI advancements. In December, the Energy Department awarded two grants for the development of small modular reactors.

Microreactors are also marketed as a source of energy that can be transported to remote and far-flung places. They offer a 'alternative to diesel generators, which require frequent fuel deliveries. Skeptics, however, have claimed that small nuclear reactors cannot generate electricity at a reasonable cost.

Edwin Lyman is the director of nuclear energy safety at Union of Concerned Scientists. He said that there was no business case to be made for microreactors. Even if they worked as intended, they would produce electricity at much higher costs than large nuclear reactors.

Wright stated that the Energy Department will have three microreactors achieve "criticality", i.e., when a nuclear reaction is able to sustain itself by July 4. According to Valar CEO Isaiah Taylor, the microreactor at Sunday's event is a little bigger than a minivan and can produce up to 5 Megawatts of energy, enough to power 5,000 houses. The microreactor will begin operating at 100 kilowatts in July and reach a peak of?250 kilowatts by the end of this year, before ramping up to its full capacity.

Valar hopes that it will be able to sell power in 2027 on a trial basis and then become commercially viable in 2028. The private sector funds its own nuclear technology development, but it needs federal support to "allow fuel fabrication and uranium enlargement here" according to Mr. He said.

Wright, a reporter at the San Rafael facility said that fuel for Valar's nuclear reactor would be transported from Nevada National Security to the San Rafael site.

Lyman stated that even small 'generators' produce a large amount of radioactive waste. Some experts say that designers are not "compelled" to take into account waste from the start, but only have to plan how it will managed. Wright stated that although the issue of disposal of nuclear waste is still unresolved, the Energy Department has been in discussions with several states, including Utah to host sites for reprocessing fuel or permanent disposal.
