What We'll Need You to Do

• Productive contribution to the development, review and maintenance of the Probabilistic Safety Assessment (PSA) as part of the overall safety assessment programme.
• Provide 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.
• Ensure that the appropriate level of quality and governance is applied to the PSA development and documentation.
• Represent 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.
• Demonstrate commitment to continuous learning and the maintenance of RR SMR’s Nuclear Safety Culture.

• Experience with PWR‑type reactor designs is ideal.
• Familiarity with applicable codes and standards (e.g. UK, IAEA, US) is an asset.
• Experience in the use of PSA to support the design of a Nuclear Power Plant (risk informed design).
• Experience 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.
• Expertise in specific topic areas as well as generalist knowledge is welcomed.
• Knowledge of data analysis will be taken under consideration.
• Familiarity 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.
• Experience 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.
• Experience working closely with engineering teams to develop an integrated engineering and safety solution and in proactively communicating across teams.
• Qualified to degree level or equivalent in Engineering, Maths, Physics or equivalent or significant relevant industry experience.
• Chartered or working towards Chartered status with a professional engineering, or equivalent, body.
