Traceable by default
Every result ships with the inputs, assumptions and model version that produced it — so a reviewer can follow any number back to its source.
New Founded 2026 · Now taking our first projects
Safety assessment for radioactive waste, rebuilt for clarity.
We model how radionuclides could move from a disposal facility to people and the environment — and deliver the evidence in a form your reviewers can trace, check and trust.

Why NuclideTrace
A new kind of assessment partner
Small and focused by design. You work directly with the people building your models.
A focused team of five
No hand‑offs through layers of management. The modellers are the people you talk to.
Conservatism made explicit
We mark exactly where conservative assumptions enter, so their effect on the result is visible.
Standards‑aligned structure
Assessment context, scenarios, models and results organised the way IAEA safety standards describe the safety assessment — ready to slot into your safety case.
Services
Everything your safety assessment needs
Disposal facility safety assessment
Operational and post‑closure safety assessment for near surface and geological disposal facilities — from assessment context and conceptual models to interpretation of results.
Discuss your facility →Scenario analysis & FEPs
Screening of features, events and processes; normal evolution, altered evolution and human intrusion scenarios.
Radionuclide migration modelling
Source term, migration through engineered barriers and the geosphere, and exposure pathways in the reference biosphere.
Uncertainty & sensitivity analysis
Probabilistic assessment and sensitivity analysis that show robustness and the parameters that matter.
Safety case support
Results documented within the argument structure of the safety case, plus support with review questions.
Waste acceptance criteria review
Consistency checks between waste characterization data and facility waste acceptance criteria (WAC).

Process
From first call to final report
- 01
Scoping
Facility, purpose, schedule and constraints. We define the assessment context together.
Scope of work · schedule
- 02
Data review
Inventory, site characterization and barrier design data reviewed; FEPs screened.
Data register · FEP screening
- 03
Model development
Conceptual models per scenario, implemented as verified calculation models.
Conceptual model report
- 04
Calculation
Deterministic and probabilistic runs with uncertainty and sensitivity analysis.
Results · sensitivity analysis
- 05
Reporting
A traceable report and support through regulatory review questions.
