Our safety case authors work alongside former regulators who have assessed submissions from the other side. Together they cover gigawatt new build, operating plant, naval bases and legacy facilities. They test whether a submission is ready before the regulator sees it.
Practice Services
Safety Cases and Safety Assessment
Structuring the argument and testing whether the evidence holds
We prepare, verify and support safety cases for new reactors, operating plant, defence facilities and legacy waste facilities, with services that include deterministic and probabilistic assessment, hazard identification and categorisation, ALARP and BAT demonstrations and the assessment of modifications.
Licensing and Permitting
Site licensing, environmental permitting and regulatory strategy
We support nuclear site licence applications, environmental permits and regulatory strategy, including engagement with ONR, the Environment Agency, SEPA and international regulators. Our team includes former regulators and licensee specialists.
Regulatory Transformation and Consenting
Consenting and regulatory reform
We support development consent, environmental assessment and the reform of regulatory arrangements for infrastructure programmes and regulators, with Collaborative Environmental Advisers contributing specialist expertise where consenting is central to the assignment.
Security, Safeguards and Emergency Preparedness
Security planning, threat assessment, safeguards and emergency arrangements
We develop security cases and site security plans, assess threats and support safeguards and emergency preparedness, working with Global Nuclear Security Partners. Emergency arrangements address the applicable REPPIR and nuclear site licence requirements.
Human Factors and Human Reliability
Safety-critical task analysis, human reliability and interface design
We integrate human factors into new designs, legacy reinstatement and operating plant. The work covers task analysis, human reliability assessment and control room and interface design, with an issues register that carries findings into the safety case.
Independent Assurance and Readiness
Our specialists independently review safety cases, programmes and organisations. They assess readiness for regulatory submission, operation or investment and serve on standing review groups.
