What do these attributes mean for common use cases?

This is an attribute check, not a project recommendation. Site, grid, licensing, fuel, security and economics still need project-specific analysis.

Common questionWhat this design data says
Grid electricity?5 MWe electrical nameplate in the current design snapshot.
Useful heat?Yes — the design is presented here with heat-use potential.
Remote / isolated deployment?Explicit transportable design attribute.
Transportable system?Yes — vendor design intent includes transportability.
Current programme phase?Testing Development / criticality testing milestone

Programme status

Development / criticality testing milestone. Prototype and licensing activities underway.

DOE / national-lab testing pathway.

Status describes the programme at the verification date. It does not imply commercial availability, licensing in your jurisdiction, construction certainty or guaranteed schedule.

Closest designs by electrical output

These are the three nearest entries in the Nuclear Planner dataset on a ratio-based MWe scale. They are not claimed to be technical substitutes.

Source and verification

Primary / authoritative source used for this snapshot →

DOE reported a September 2026 criticality-testing milestone. Output specifications come from Westinghouse product materials.

Verified 2026-09-21. If the programme has moved since then, use the linked source as the current authority.
