Commercially established fuel
The design basis under development uses an established oxide-fuel family, selected to begin from a mature industrial and regulatory foundation.

Practical technology
Neutronix is developing a system around established technology families selected for the complete path from analysis to fabrication, transport, licensing, and qualification.
Technology basis
The current design basis is under development. These families describe the public technology direction without disclosing proprietary design values.
The design basis under development uses an established oxide-fuel family, selected to begin from a mature industrial and regulatory foundation.
A metallic cladding family is being evaluated for familiar fabrication, inspection, material-performance, and licensing evidence pathways.
Graphite moderation and reflection provide a well-characterized technical basis with an established body of analysis and operating experience.
Helium is chemically inert. Its system implications still require disciplined thermal, leakage, materials, maintenance, and qualification work.
Selection discipline
A promising material or component can still create unacceptable risk at another interface. The selection process follows the full system and lifecycle.
Fuel, cladding, moderator, reflector, coolant, structures, controls, and balance of plant are assessed as an interacting system rather than optimized in isolation.
Design choices are evaluated against repeatable fabrication, inspectability, realistic tolerances, quality assurance, and the capabilities of qualified suppliers.
Transport is treated as a design input. Packaging, handling, route, security, regulatory, and site-interface requirements remain configuration-specific.
Material availability, supplier maturity, lead times, quality programs, and substitution risk are considered before a technology is treated as deployment-relevant.
Existing evidence and regulator familiarity can inform the development path. Familiarity is a selection criterion—not a claim of approval or a shortened schedule.
Non-nuclear qualification
The development approach is intended to connect analysis with reproducible non-nuclear tests before design objectives are represented as demonstrated performance.
Use physics, thermal, structural, materials, controls, manufacturing, transport, and site models to expose interface risks early.
Develop component and loop tests that reproduce relevant mechanical, thermal-fluid, instrumentation, and control behavior without operating a nuclear system.
Use test results to update models, define acceptance criteria, support supplier qualification, and build the evidence required for later regulatory review.
