Safety Case Engineer - Probabilistic Safety Assessment

Do you enjoy working with statistical methods of analysis, safety risk modelling and developing safety case justifications using quantitative and mathematical methods? If you are skilled in probabilistic safety assessment or safety case development, or would like to develop the skills, we have the role for you in the Nuclear Operations Design Authority, supporting Sizewell B, the UK's only operating PWR., The role is primarily as a Safety Case Engineer, with PSA focus. You will maintain safety cases using both deterministic and probabilistic methods, leading Category 1 and complex Category 2 Engineering Changes (ECs), providing safety case advice and emergent technical support to stations and other departments, and overall, maintaining the integrity of design of the nuclear fleet over their entire lifetime in order to achieve a continuous high level of safety. The role involves being a key interface between the operational licensed sites and the UK nuclear regulator.

As the Design Authority of the Nuclear Operations business, we have a central role in developing, maintaining and reviewing nuclear safety cases for our eight nuclear power stations in the UK. As such, our role covers the generating AGRs and Sizewell B (SZB) along with the stations that are transitioning from operation to decommissioning.

We have a specific need in the Probabilistic Safety Assessment (PSA) area, but successful applicants will be required to work flexibly across different technical disciplines, with training and mentoring support provided where needed. The work will have a focus on supporting safe generation at Sizewell B, the UK's only generating PWR, and extending its generating lifetime to at least 2055.

PSA is an essential part of the safety case that is necessary to demonstrate that risks remain acceptably low. PSA includes methods such as fault tree analysis, event tree analysis, statistical risk modelling, quantitative risk assessment and safety assessment of risk. The role will involve liaising with contract partners who develop the numerical models and interpreting the results for real life safety decisions - including operating and modifying the nuclear plant. It will give you opportunity to develop a broad understanding of the plant, the safety case, requirements of operational stations and regulatory interactions. Successful candidates will have a primary role in supporting the PSA aspects of the safety case but will be also required to support broader requirements. We are committed to developing agile engineers for the future and embrace opportunities across AGRs, Sizewell B, Hinkley Point C, Sizewell C and any other new build stations.,

• Developing strategies for maintenance and revision of the safety case.


• Producing new or revised safety cases for normal operation, reactor faults and hazards.


• Acting as Case Officer, Author, and Verifier for nuclear safety significant Engineering Changes (category 1 and complex category 2).


• Conducting and reviewing probabilistic analysis and management of probabilistic models and data


• Interpreting analysis results to provide advice to support safety case development


• Developing and implementing modifications to power station plant, processes, and procedures to ensure compliance with safety case requirements.


• Providing safety case advice and maintaining safety case health.


• Ensuring that requirements are met for plant outages and major plant modifications


• Interfacing with the UK Nuclear Regulator.


EDF has a structured and detailed training process, and you'll be in a team of safety case and PSA engineers so you'll be well supported as you develop the skills.

We are looking for experienced engineers, ideally with a proven record of delivery in a safety assessment role within a safety-critical environment. We want you to contribute to, and ultimately take a lead in, technically challenging work. Along with this, your roles and responsibilities also include, To be successful in this role, we're looking for you to hold a minimum of a HNC or equivalent in Engineering, Physics, Mathematics or a similar technical discipline with a background/experience in Safety Case Engineering.

You will have the ability to work across functions and engage with stakeholders at all levels while dealing effectively with differing stakeholder expectations and proven experience of delivery to stretching targets within a technically challenging engineering environment.

You'll have a strong safety culture with an emphasis on application of engineering judgement to identify fit-for-purpose solutions for safety-related tasks and be able to work on own initiative and apply scientific/technical training to identify and resolve operational problems.

At EDF, everyone's welcome. We strive to create an inclusive and diverse environment where everyone has a voice and where you feel confident being yourself. We're committed to equality, diversity, and inclusion. We'd like our future workforce to have an equal gender balance, represent a broad mix of people from minority ethnic backgrounds, LGBTQ+, those with a disability and supporting social mobility.

We're a disability confident employer and we'll do all we can to help with your application, adjusting as you need.

We'll value the difference you bring and offer opportunities for you to thrive and succeed.

We can offer a competitive salary from £40,069 - £84,892 and you'll be appointed based on the parameters outlined in the Nuclear Generation Company Agreement based on your demonstration of competences, experience, and qualifications. This is a full-time position; however, we will be happy to discuss options regarding part time flexibility to support home-life arrangements and/or job share if you would like to highlight this on your application.
