Nuclear Science and Technology & Physics-Informed Machine Learning

Physics-grounded modelling, learning and validation for Nuclear Science and Technology

Nuclear Science and Technology covers nuclear/particle interactions, neutron and radiation transport, reactor physics, thermal hydraulics, fuel/materials, instrumentation, waste and radiation protection. PIML can accelerate high-fidelity models and infer hidden parameters.

This is a high-consequence domain. Learned models may support analysis and monitoring only within rigorous verification, validation, uncertainty, defence-in-depth and regulatory controls; they cannot replace licensed protection systems.

This page presents ten focused research areas, degree-level project pathways, selected publications and direct support through the PIMLS biweekly members meeting.

This Nuclear Science and Technology guide covers Physics-Informed Neural Networks (PINNs), physics-guided machine learning, scientific machine learning, neural operators, hybrid models and engineering digital twins. Explore the research and project pathways below, then join the Physics-Informed Machine Learning Society to connect with the international PIMLS community.

Why this combination matters

Why Nuclear Science and Technology Needs Physics-Informed Learning

Use available scientific knowledge to make limited data more useful, transparent and testable.

Expensive models and experiments

PIML can reduce repeated simulation or experimental cost while retaining the governing knowledge used in Nuclear Science and Technology.

Incomplete engineering models

Learn uncertain parameters, closures or discrepancies around an inspectable mechanistic foundation.

Transfer across conditions

Test whether structured models generalize across geometries, materials, assets, operating regimes or sites.

Trustworthy evidence

Use physical residuals, independent measurements, uncertainty and conventional engineering baselines before deployment.

Ten focused directions

Major Nuclear Science and Technology PIML Research Areas

Each card connects a meaningful Nuclear Science and Technology question with suitable scientific knowledge, modelling choices and evidence needed to test it.

Before you begin

Frequently Asked Research Questions

These answers help students avoid common scope, terminology and validation mistakes.

Still have a question?

Use the biweekly meeting form for research guidance.

Request access

No. Nuclear Science and Technology projects may use physics-guided features, hybrid residual models, differentiable simulators, neural operators, constrained architectures or data assimilation. State exactly what knowledge is incorporated.

Choose one engineering question, a measurable output and a defensible mechanistic baseline. Add learning only where data can identify an uncertainty or discrepancy.

A meaningful question, justified prior knowledge, deployment-level holdouts, strong baselines, ablation, uncertainty, reproducibility and honest limitations.

Simulation can broaden coverage, but simulation-only evidence cannot establish real-system accuracy. Use calibrated experiments, field measurements or trusted independent references appropriate to the claim.

Submit the biweekly members meeting form to discuss your project level, branch, data, model, validation plan and possible collaborators.
