What the evidence supports
That U.S. Nuclear Regulatory Commission (Federal Register), the regulator, published the quoted statement. It records "design disclosed" for Hermes 2 design as described in the NRC docketing notice (original two-unit design) under technical milestones only.
What remains unknown
A disclosed design is not a tested one. Performance at commercial scale, sustained output or independent confirmation, unless the quoted passage states them.
