NTRAF section 2 and section 3.5 / Prototype development

What TRL 6 means

Representative model or prototype system, well beyond TRL 5, is tested in a relevant environment. The step up from laboratory scale to engineering scale.

Criteria reviewers look for

• Representative model or prototype is tested in a high-fidelity environment.
• Major production issues are identified and resolved.
• Engineering feasibility is fully demonstrated.

Evidence examples

• Pilot demonstration report
• System specification
• Transition plan

Next action

Demonstrate a full-scale prototype in the operational setting.
