## Summary

This September 25, 2025 article from the American Nuclear Society covers Valar Atomics' groundbreaking ceremony for the Ward 250 test reactor at the San Rafael Energy Research Center in Emery County, Utah. The ANS is a professional society for nuclear scientists and engineers; its news coverage provides a credentialed technical publication's account of the groundbreaking milestone.

## Useful Claims

- Valar Atomics broke ground on its Ward 250 test reactor at the San Rafael Energy Research Center in Utah in September 2025.
- The Ward 250 is described as a high-temperature gas reactor (HTGR) using TRISO fuel and helium cooling.
- The San Rafael Energy Research Center in Emery County, Utah is the designated test site for the Ward 250 program.
- The groundbreaking represents an early physical construction milestone, distinct from later criticality and power-operation milestones.
- The article provides an independent technical publication's account, corroborating Valar Atomics' own mission-page claims about the Utah test site and program timeline.

## Reliability Notes

The American Nuclear Society is a professional membership organization for nuclear engineers and scientists; its news articles are written by technically literate journalists and editors, making this a more credible source than a company press release for validating factual claims about reactor design and program milestones. The article does not substitute for NRC regulatory documentation or independent safety analysis, but it provides a reliable external account of the groundbreaking event and program context. Timeline claims about subsequent milestones (criticality, power operations) should be verified against later coverage.
