Overview
Originally named, Great British Energy - Nuclear,
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.
Great British Energy - 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 had been selected as the preferred bidder to build the UK's first SMRs, following a technology selection process that began in 2023.
Great British Energy - 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-E 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

Job Profile:
The Safety, Security, Safeguards and Environment (SSSE) Lead will be part of the Technical function, reporting to the Technical Director, who is responsible for all aspects of nuclear safety and assurance interface management requirements.
The SSSE Lead will be responsible for development of the requisite SSSE cases to support successful deployment of the SMR project, ensuring relevant regulations and relevant good practice are met. They will work closely with the SLA Director to develop and implement the project SSSE strategy, and subsequently be responsible for their development.
You will form part of the establishment of a major programme. This will provide you with an opportunity to be part of a team that ensures successful delivery of a First of a Kind (FOAK) UK SMR Project, helping to ensure that it minimises its environmental impact whilst delivering cost-effective energy capacity. Whilst this is a fast-paced and exciting challenge, you will need to be comfortable with uncertainty, ambiguity and change.
Responsibilities:
* Development of the project SSSE strategy, in close collaboration with the Safety Licencing and Assurance Lead. Develop, implement and maintain a clear strategy for the ongoing management of the project SSSE cases in line with the relevant process arrangements.
* Lead development of required SSSE top tier reports and plans (e.g., PCSR, PCER, Nuclear Site Security Plan, Basic Technical Characteristics etc.,) in accordance with the SSSE strategy
* Work with the wider technical team and Technology Partner to ensure delivery of the required information to underpin the SSSE reports (i.e., the SSSE case), ensuring integrity of the golden thread and completeness of information
* Ensure all SSSE documentation is prepared in line with national and international nuclear regulations and adequately addresses all technical, operational, and environmental risks associated with the SMR Project.
* Work with the relevant permissions and licensing leads to ensure SSSE reports and underpinning documentation are delivered as required to support permitting, licensing and consenting activities
* Ensure required SSSE documentation is submitted to regulatory bodies on the agreed timescales. Serve as a key contact for regulatory bodies (e.g., ONR, EA) concerning SSSE submissions and enquiries.
* Collaborate with technical, digital, project management, and commercial teams to ensure seamless integration of SSSE requirements within the broader project scope.
* Ensure any changes to regulatory frameworks or emerging best practices are considered and reflected in the SSSE strategy and plans updated in response.
* Foster a positive and inclusive team environment that aligns with cultural values.
* Contribute to maintaining a respectful and collaborative workplace, valuing diversity, and promoting teamwork.
* Make informed decisions and solve problems effectively, considering diverse perspectives and organizational goals.
Knowledge, Skills and Experience required:
* Experience in nuclear safety case, site security, or environmental protection within the nuclear energy sectors.
* Experience in leading SSSE case development activities, ideally for complex nuclear projects or other highly regulated industries.
* Strong understanding of the relevant regulatory requirements, in particular those relevant to nuclear new build in the UK (i.e., ONR, EA)
* Exceptional communication skills, with the ability to effectively interact and explain complex processes with technical and non-technical stakeholders.
* The capability to embrace change and uncertainty and welcome the emergent aspect of the job.
* Ability to foster a collaborative and supportive environment, whilst developing team members' skills and capabilities.
* Ability to work in a collaborative, multi-party environment at pace.
Qualifications:
* A bachelor's or Master's degree in a STEM discipline
* Chartered status with a recognised engineering or regulatory institute (e.g., Chartered Engineer, Chartered Environmentalist).
