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 question | What this design data says |
|---|---|
| Grid electricity? | 125 MWe electrical nameplate in the current design snapshot. |
| Useful heat? | Yes — the design is presented here with heat-use potential. |
| Remote / isolated deployment? | Not a primary small/remote scale signal. |
| Transportable system? | No — this profile treats it as a fixed-site design. |
| Current programme phase? | Under construction Under construction / commissioning tests |
Programme status
Under construction / commissioning tests. Demonstration unit at Changjiang completed cold functional testing in October 2025.

CNNC reported the primary-circuit cold functional test completed on 16 October 2025 and described hot functional testing, fuel loading and commercial operation as subsequent steps. The status remains under construction / commissioning tests until a later authoritative operating milestone is verified.
