Probabilistic Safety Analysis Method



Our Client is an innovative nuclear power start-up. Backed by over €300million+ in funding, our Client is accelerating developments in MOX fuel and in the design and developments of 4th Generation LFR nuclear reactors.

 Overview of the role 

Working in the Safety and Licensing for Design (SLD) function of Global Engineering you will be supporting programmes in France and UK working closely with the Design teams. We are looking for a Nuclear Safety Analyst, more specifically in the field of Reactor Safety studies.

You will report directly to the Safety & Licensing for Design (SLD) Head of Unit.

As a Safety Analyst, you will be responsible for the execution of technical studies, management of suppliers and producing reports supporting the design stages within various programmes.

Main duties/role and responsibilities  

  • Developing Probabilistic Safety Analysis (PSA) models for plant designs.
  • Collaboration with design teams to ensure probabilistic models reflect the evolving design, and to pass risk-informed design insights to design teams.
  • Using PSA models to evaluate overall plant risk levels, and to carry out a range of appropriate sensitivity analyses of the design.
  • Writing summary reports to represent PSA results in the safety documentation.
  • Interacting with regulators.

Attributes/Experience Required 


  • MSc degree, or an equivalent level of experience in a relevant domain


  • English (Required): Proficiency in both written and spoken English is a mandatory requirement for this role. Clear and effective communication in English is essential for day-to-day responsibilities, team collaboration, and interactions with stakeholders across the organization.
  • Italian and French (Desirable): While not mandatory, a basic to intermediate level of proficiency in Italian and French is desirable for this position. The ability to communicate in Italian and French can be advantageous, as it will facilitate effective liaison and collaboration with our French and Italian teams.

Experience / Professional requirements:

  • Strong interest in nuclear engineering, in particular in the development of the fourth generation of reactor technologies.
  • At least 5 years’ experience in Probabilistic Safety Analysis using one of the major PSA codes (e.g. riskspectrum), developing fault trees and event trees of a range of typical systems and components.
  • Experience in Level 1 and Level 2 PSA is required, experience in Level 3 PSA is desirable but not required.
  • Desirable to have experience in modelling / reliability analysis of passive systems.
  • Experience of wider fault analysis (deterministic, severe accident) is desirable.


  • This role can be based in our Manchester or Gloucester offices, with a minimum of 3 days a week attendance in the office.
  • Regular business travel will be required to our offices in Turin (Italy) and Lyon (France), in order to collaborate and build strong working relationships within our Global Engineering Team.
