Our Small Modular Reactor technology combines decades of engineering expertise with innovative manufacturing approaches to create safe, reliable and affordable clean energy solutions. Joining us means contributing to one of the UK's most significant engineering programmes and helping shape the future of energy.\nThe Role\nAs a Probabilistic Safety Engineer are a technical professional in the Rolls-Royce SMR PSA team and contribute to a diverse team supporting the development of the Rolls-Royce SMR Power Station and the successful completion of first the Generic Design Assessment (GDA) and then later licensing and permitting processes. There will be an opportunity to support compliance with international licensing regimes\nWhat We'll Need You to Do\nProductive contribution to the development, review and maintenance of the Probabilistic Safety Assessment (PSA) as part of the overall safety assessment programme. \nProvide support to engineering disciplines in their decision-making process enabling PSA results to be considered as an input to choose between different design options that are under consideration. \nEnsure that the appropriate level of quality and governance is applied to the PSA development and documentation. \nRepresent the project at appropriate internal technical and project reviews along with relevant team members and occasionally at external meetings with the regulator and other stakeholders. \nDemonstrate commitment to continuous learning and the maintenance of RR SMR’s Nuclear Safety Culture. \nKeep up to date with developments in the nuclear industry and the work of the appropriate external industry groups in the UK and worldwide including the identification of useful industry events. \nWhat You'll Bring\nExperience in the development and application of PSA to nuclear facilities, preferably to a complex facility such as an operating Nuclear Power Plant (includes Level 1, Level 2 and Level 3 PSA).\nExperience with PWR-type reactor designs is ideal. Familiarity with applicable codes and standards (e.g. UK, IAEA, US) is an asset. \nExperience in the use of PSA to support the design of a Nuclear Power Plant (risk informed design).\nExperience in PSA topics including development and application of fault trees and event trees, reliability data analysis, internal and external hazards, risk monitor, and system dependency topics. Additionally, expertise in the interpretation of PSA results and their application is required.\nExpertise in specific topic areas as well as generalist knowledge is welcomed. Knowledge of data analysis will be taken under consideration.\nFamiliarity with PSA software analysis tools, particularly Risk Spectrum PSA. Familiarity with Pheonix Architect will be considered. Familiarity with writing macros in Excel and knowledge of SQL is an advantage.\nExperience in the development of PSA and its documentation to ensure the documentation clearly and comprehensively documents the model and presents a range of results suitable for the target audience needs. \nExperience working closely with engineering teams to develop an integrated engineering and safety solution and in proactively communicating across teams \nQualified to degree level or equivalent in Engineering, Maths, Physics or equivalent or significant relevant industry experience.\nChartered or working towards Chartered status with a professional engineering, or equivalent, body.\nLocation\nThis role can be based in Warrington, Derby or Manchester, with hybrid and flexible working arrangements available. We recognise that no candidate will meet every requirement, so if you believe you are a strong match for most of the role, we would encourage you to apply.\nWhat’s in It for You\nA salary between £42,000.00 - £55,150.00, £2,200 benefit allowance, 12.5% bonus opportunity, 6x pensionable life assurance, 50% income protection, 28 days’ holiday plus bank holidays, and a £250 new-joiner payment -alongside opportunities for development and progression.\nSelection Process\nShortlisted candidates will be invited to a competency-based interview and may be asked to provide evidence of document management capability.
