Manufacturing feasibility assessment
5. Verdict
Commercial fission reactors are feasible, but licensing, nuclear-grade QA, fuel, safeguards, and site infrastructure require major investment; first define power, jurisdiction, and reference design.

At a theoretical 10,000-unit run, tooling amortises to roughly US$80k-US$250k per unit, but this volume is not a credible near-term nuclear market. At 10-100 units, amortisation is US$8M-US$250M per unit; a US$50M retail point is not viable for a utility-scale reactor, while US$1B-US$5B may support a licensed FOAK depending on site scope.
8. Gates to clear
8.1 [DFM]
The pressure vessel, safety-class I&C and containment require nuclear-grade suppliers, fully traceable materials and qualified fabrication; these cannot be treated as ordinary modular hardware.
Path: Freeze a standard light-water reactor design, engage ASME Section III/NQA-1 qualified fabricators, produce full-scale weld and vessel coupons, then qualify a repeatable factory acceptance-test and site-module integration sequence.
8.2 [Certification]
There is no global nuclear approval. Each deployment needs national licensing, safeguards, environmental review, security approval and an approved waste/fuel pathway.
Path: Select one anchor jurisdiction first: pursue US NRC Part 50 or Part 52 licensing, then use country-specific pathways such as CNSC VDR in Canada, UK GDA/ONR review, and national regulator review in each target state; align safeguards with IAEA requirements and local operator licensing.
8.3 [Tooling]
Nuclear tooling and design certification consume billions before revenue, while realistic early production is tens of units rather than thousands.
Path: Fund a government-backed FOAK program, lock a utility fleet order with milestone payments, use existing nuclear-qualified vessel and turbine suppliers initially, and add dedicated tooling only after a multi-unit follow-on order.
9. Prototype sequence
- 9.1Define one reference product: a standardized 50-100 MWe light-water SMR or a non-power research reactor, with a single anchor-country site assumption.A reactor cannot be costed, licensed or manufactured against a broad utility-and-research brief without a fixed power class and design basis.
- 9.2Run regulator pre-application engagement and establish the licensing basis, safeguards plan, security concept and spent-fuel strategy.These inputs determine the safety architecture and prevent expensive redesign after engineering has started.
- 9.3Build non-nuclear thermal-hydraulic, controls and full-scale fabrication qualification rigs; qualify the nuclear supply chain to ASME Section III and NQA-1.This retires manufacturability and safety-system risk before committing to a nuclear prototype.
- 9.4Complete detailed design, probabilistic safety assessment, environmental review and construction-license submissions for the selected jurisdiction.The first nuclear unit must be built under an approved regulatory and site-specific framework.
- 9.5Construct one FOAK at a host utility or national laboratory, commission under regulator hold points, then operate through a monitored demonstration period.Only operating evidence establishes maintainability, availability, fuel performance and the basis for fleet replication.
- 9.6Release a constrained fleet design after FOAK lessons, with configuration control and supplier capacity reservations.Repeatability is the only credible route to lower cost; premature volume promises would not be bankable.
