New Hampshire’s legislative initiatives, such as HB 710 supporting clean energy, and provisions for SMRs, could create a favorable policy environment for advanced nuclear technologies [NH.gov](https://www.nh.gov). However, Valar Atomics’ current projects are located in Utah, with no expressed interest or connections to the Northeast U.S. in available data. Their technology readiness, with Ward 250 still in the construction phase, suggests deployment timelines may not align with immediate NH needs. Long-term, their focus on cost-effective, scalable reactors could address industrial heat or grid power demands in the state, provided regulatory and community support aligns. ### Competitive Position Valar Atomics operates in a competitive landscape of nuclear startups focusing on SMRs and advanced reactors. Compared to **[[NuScale Power]]**, which has an NRC-approved design for its 77-MWe VOYGR reactor and is closer to commercial deployment, Valar is earlier in development with Ward 250 at the test stage. **[[Aalo Atomics]]**, another DOE Pilot Program participant, broke ground on a 10-MWe reactor in Idaho in August 2025, slightly ahead of Valar’s Utah milestone [ANS.org](https://www.ans.org/news/2025-09-25/article-7408/valar-atomics-breaks-ground-in-utah/). **[[Oklo]]**, focusing on fast reactors, also benefits from DOE support and modular construction approaches, posing competition in cost and scalability. Valar’s unique advantage lies in its early achievement of criticality with Project Nova, demonstrating technical capability and strong DOE ties. However, risks include regulatory delays and the challenge of scaling from test reactors to commercial operations in a capital-intensive industry. ### Closing Note Valar Atomics is an early-stage nuclear startup with promising milestones in criticality and pilot reactor construction, poised for growth under supportive U.S. policies, though commercial deployment remains on the horizon. *Report generated December 24, 2025*
