Bringing a new reactor design into the real world takes more than ambition and good physics — it takes a structured path to credibility.

Advanced reactor developers come to Gibboney Nuclear when they realize they need expert guidance to align their design, safety case, QA foundations, and regulatory strategy with what investors and regulators expect.

Gibboney Nuclear is registered with the U.S. Department of Commerce Bureau of Industry and Security (BIS), utilizes SNAP-R reporting where applicable, and works in coordination with an export controls specialist to support compliant execution of regulated nuclear work.

Whether you’re designing your first reactor or scaling toward demonstration, we help you build a program regulators trust and investors believe in.

Executive Advisory Services

Independent Technical & Regulatory Authority

Delivered personally by Sarah Gibboney, P.E., this offering provides executive-level judgment for nuclear leaders navigating regulatory, investor, and schedule pressure.

Executive Advisory Services focus on decision quality, not document production. This work helps CEOs and founders align design maturity, quality assurance, and safety basis with what regulators and investors will actually accept.

Typical focus areas include:

DOE / NRC authorization strategy
QA and design control governance
Safety-basis alignment and readiness
Design maturity and interface risk
Executive decision support during critical milestones

This service is not staff augmentation and does not replace internal engineering or QA teams. It is designed for leaders who want clear, independent judgment early enough to change outcomes.

All advisory engagements operate under an Authority Charter to ensure recommendations are acted on, or consciously declined with full visibility of risk.

Best suited for organizations that value discipline over speed theater.

FREE RESOURCE: Reactor Program Maturity Index (RPMI)

Take the RPMI

A 10-Category Self-Assessment for Founders & Investors
Identify your strengths, uncover blind spots, and understand how your reactor program will be evaluated by both regulators and investors.

The RPMI covers:

Physics & neutronics validation maturity
Safety basis and accident analysis readiness
QA/QAPD implementation depth
Configuration management discipline
Licensing strategy realism
Supply chain and manufacturability alignment
Program execution capability

Why it matters:
Most reactor startups don’t know where their real gaps are.
The RPMI shows you — before the regulator or investors do.

Advanced Nuclear Readiness & Direction Assessment (ANRDA)

Clarity before your next major decision

Advanced reactor programs rarely fail on physics.
They stall when early design, QA, and regulatory decisions quietly outrun licensing reality.

The Advanced Nuclear Readiness & Direction Assessment (ANRDA) is a focused, reactor-specific diagnostic that helps teams answer one critical question:

Where should we invest our next dollars and effort to reduce licensing and execution risk—before it’s too late to change course?

What ANRDA does

ANRDA builds on your RPMI results and dives deeper into the areas that matter most for your specific design.

It evaluates how your:

Licensing pathway
QA posture
Safety basis
Governance and decision structure

will hold up under real DOE or NRC scrutiny, not theoretical standards.

The goal is not scoring—it’s direction.

What you receive

A confidential, written assessment that:

Identifies your most consequential readiness gaps
Explains why they matter for licensing and schedule
Prioritizes what must be addressed now vs. later
Guides where to focus your next phase of investment

Teams use ANRDA to align leadership, brief investors, and avoid preventable resets.

Who it’s for

ANRDA is designed for teams that:

Are approaching DOE or NRC engagement
Are preparing for a major funding or demonstration milestone
Want clarity before committing significant capital

How it fits

RPMI → where you stand
ANRDA → what to do about it
Full Engagement → execution

ANRDA often pays for itself by preventing one major licensing or program misstep.
