Operational Capability Senior Specialist

Great British Energy
- Nuclear is an arm’s length body of the Department for Energy Security and Net Zero, dedicated to supporting the development and deployment of new nuclear technologies in Great Britain. We play a crucial role in advancing nuclear new build, ensuring the UK’s energy security and achieving net-zero carbon emissions. Great British Energy
- Nuclear focuses on fostering innovation, facilitating investment, and coordinating efforts across the nuclear industry to build a resilient and sustainable energy future.

- Nuclear’s first step was to start the technology selection process for Small Modular Reactors (SMRs) in 2023. SMRs can potentially be quicker to deploy and less expensive to build than traditional nuclear power plants because they are smaller, have factory based modular manufacturing and more flexible deployment options. In June 2025, Great British Energy
- Nuclear announced that Rolls-Royce SMR was selected as the preferred bidder to build the UK’s first SMRs, following a technology selection process that began in 2023.

- Nuclear is aiming to deliver fast, based on a supportive and collaborative culture which values equality and diversity and creates an inclusive workplace. We draw on deep nuclear expertise – our Executive Committee has over 100 years of nuclear experience at home and abroad. GBE-N will unlock billions of pounds of private and public investment from design to operation, helping to get sites ready for development, and working to grow manufacturing capacity and skills capability.

Our activities will be driven by our values, which are:

Trust - We prioritise safety, we act responsibly and with integrity.

Collaboration - We work as a team; we value diversity and expertise.

Challenge - We are curious and courageous in the way we think and act.

Responsible for defining and reviewing organisational capability requirements to support the deployment of a Small Modular Reactor (SMR) fleet across the UK. This role involves assessing end‑to‑end operational readiness, including workforce planning, training frameworks, asset management strategies, digital infrastructure, and documentation control to ensure alignment with nuclear site licence conditions and regulatory expectations.

• Evaluating operational capability across all lifecycle phases: commissioning, operations, maintenance, and decommissioning.
• Reviewing vendor design submissions to ensure operational feasibility, maintainability, and compliance with UK nuclear safety standards.
• Defining staffing models and competency frameworks in accordance with ONR guidance and nuclear baseline requirements.
• Identifying digital system requirements for plant configuration control, work management, and operational decision support.
• Supporting the development of site documentation, including operating instructions, maintenance procedures, and safety case inputs.
• Advising on commissioning plans and readiness assessments to ensure safe transition to operational status.
• Engaging with cross‑functional stakeholders including engineering, operations, regulatory affairs, and supply chain to ensure integrated delivery.

• Experience in the operation of UK nuclear power plants (AGR, PWR or equivalent), gained within operations, maintenance, engineering,…
