Valar Nuclear partners with Nvidia to create a data center that conserves water

Valar Atomics, a nuclear energy startup, announced?on Wednesday that it was partnering with Nvidia to develop a small Utah data center. The companies claim this will demonstrate how computing facilities required for AI can save water.

Valar, a Californian company, announced its partnership with Utah's microreactor plant. The company also conducted a demonstration using Nvidia Blackwell, the latest AI chip architecture designed for data centres. The companies claimed that it was the first time a small reactor has powered a data centre.

Valar is among a group of 10 startups participating in the Department of Energy's reactor pilot program. The goal was to demonstrate that three small reactors could reach criticality by July 4, when a nuclear reaction would be able to "sustain" itself.

Nvidia announced that its latest data centre design, DSX, would be using closed-loop fluid cooling. It claims this method can reduce water consumption for facility-cooling from 2.6 million gallons of water per megawatt annually to 'near zero.

DATA CENTER OPPOSITION GREENERS Concerns?over the U.S. Data Centers' need for water and power have led to a growing backlash.

A recent /Ipsos survey showed that only 1 in 3 Americans approved of the rapid pace of construction of data centers, a topic on voters' minds ahead of the midterm elections scheduled for November 3.

In order to avoid permitting, stakeholder engagement with the public and grid interconnection, companies have sought to generate their own electricity through private or "behind the meter" plants.

The projects are mostly natural gas-based, but some companies have their eyes on small nuclear reactors that could be used to power AI infrastructure.

WHITE HOUSES?PUSHES RACTORS

The administration of President Donald Trump sees the small nuclear reactor as one way to increase?power production. Trump issued executive orders in?May aimed at quadrupling the nuclear deployment.

John Josephakis is a global vice president at Nvidia. He said, "Through the work done with Valar Atomics Nvidia explores how advanced nuclear systems that are waterless and behind-the-meter could support future AI factories designed for scale and reliability required by accelerated computing."

Founder Isaiah Taylor of Valar said that the company is trying to show that nuclear projects can be completed quickly, despite long regulatory obstacles. Valar claims its high-temperature reactor is cooled by helium rather than water.

Valar has joined a lawsuit against the Nuclear Regulatory Commission brought by Texas and Utah last year, arguing it lacks licensing authority for some microreactors or small modular reactors. Valar wants to hand this oversight over to the individual states.
