CSMC is developing POLAR-1 to supply continuous electricity and heat to northern, Indigenous, industrial and defence sites. Its proposed transportability and remote monitoring address the logistics of off-grid power. Exact electrical and thermal ratings, transport mass and service intervals are not specified in the launch materials.
Technical detail

Designed for military-aircraft transport, including the C-17
Remote monitoring and long service intervals are design goals
Microreactor
Remote power
Thermal energy
Use & integration
Recorded applications
Northern and off-grid electricity and heat
Remote industrial and defence infrastructure
These describe the reviewed application scope, not confirmed deployments, released requirements or procurement eligibility.
Evidence of maturity
Company target: first criticality by 2028. The CEO describes a criticality experiment and safety-system validation rather than a completed power plant; no demonstrated TRL is assigned.
Commercial availability
Company target for fleet deployments beginning in 2030; this is not an operating fleet or a delivery commitment.
