ABOUT US

About Sentinel Nuclear Consultancy

Vision: to become a globally recognised independent nuclear consultancy trusted to build the organisations, capabilities and operating cultures required for safe, secure, reliable and sustainable nuclear energy.

Mission: integrated, independent, evidence-based advisory services strengthening regulatory capability, safety assurance, competent people, effective organisations and operational excellence throughout the lifecycle.

Sentinel is an independent partner to the owner/operator, providing practical advice, capability development and evidence-based assurance. We are not an EPC contractor, reactor vendor or regulator.

A successful nuclear project is not only one that constructs a facility; it is one that leaves behind an organisation able to operate it safely for decades. Physical delivery can outpace the owner/operator organisation, creating risk in licensing, construction oversight, commissioning, workforce readiness and handover. We integrate regulatory, safety, organisational, workforce and operational requirements, tracing obligations through safety case, organisation, procedures, competence and evidence.

Programme Advisory

Better early decisions on nuclear strategy, technology, procurement and licensing.

Organisation and Capability

Clear accountabilities, competent personnel and effective owner/operator capability.

Operational Excellence

Successful transition from project delivery to safe, reliable and continuously improving operations.

EXPERTISE

Areas of Nuclear Expertise

Six integrated capability groups supporting nuclear organisations from programme development through operational excellence.

Each capability group can be delivered as a diagnostic assessment, an improvement programme, embedded advisory support or independent assurance.

Does the organisation being created today have the capability required to operate the facility safely tomorrow?

            7. FLAGSHIP PROGRAMME

            Construction-to-Operations Transition and Operational Readiness Programme

            Prepares the permanent operating organisation to assume responsibility as the facility moves from construction through commissioning, fuel loading, start-up and commercial operation.

            Knowledge and Responsibility Transfer

            Manages the planned transfer of knowledge, responsibility, authority and accountability from vendors and project teams to the owner/operator, and coordinates handover of people, plant, records, configuration, procedures, training, maintenance capability, safety-case ownership, supplier knowledge and regulatory commitments.

            Operational Capability Development

            Develops organisation, procedures, competence, maintenance, work management, emergency arrangements, security and decision-making capability before fuel load and commercial operation.

            Eight Readiness Gates

            A structured progression towards safe and reliable nuclear operations.
