Valar Atomics "Nuclear Gigasite" model — clustering hundreds of identical High-Temperature Gas Reactors (HTGR) on a single remote heavily-regulated site — will emerge as the dominant deployment architecture for advanced fission, superseding scattered SMR approaches. | Valar first fueled reactor site announcement

Key catalyst: Valar first fueled reactor site announcement

Watch events: Valar first NRC pre-application meeting; first fueled reactor site selection; capital raises

Ward Zero non-nuclear thermal prototype completed in ~10 months (early 2025). Valar has raised ~$19M seed. Licensed site and first fueled reactor still pending.
