Senior Probabilistic Safety Assessment Engineer (F/H)

About newcleo:

Privately funded and headquartered in London, newcleo was launched in 2021 – and since raised over EUR 400 million – to be an innovator in the field of nuclear energy. Its mission is to generate safe, clean, economic and practically inexhaustible energy for the world, through a radically innovative combination of existing, accessible technologies.

With visionary co-founders, newcleo capitalises on thirty years of R&D activity in metal-cooled fast reactors and liquid-lead cooling systems, and our senior management and advisory team can boast hundreds of years in cumulative hands-on experience.

Counting on over 750 highly skilled employees across Europe, newcleo has business, scientific, operations and industrial manufacturing capabilities in a vertically integrated model designed to deliver its ambitious timeline for its plan-to-market.

newcleo’s technology, mostly comprising a novel approach to already qualified solutions, addresses equally well the three challenges affecting the nuclear industry to date: waste, safety and cost.

• Waste: fast reactors are capable of efficient “burning” (i.e., fission) of depleted uranium, plutonium and Minor Actinides. When operated with MOX fuel generated from reprocessed nuclear waste, newcleo’s reactors not only ensure sustainability by closing the fuel cycle but can also boost energy independence.
• Safety: lead-cooled reactors operate at atmospheric pressure. The properties of lead (thermal capacity and conductivity, boiling point, chemically inert, low neutron activation, shielding properties) together with newcleo’s passive safety systems ensure very high levels of safety
• Cost: newcleo’s reactor design has been optimised over the last 20 years leading to the concept of an ultra-compact and transportable 200MWe module with improvements in energy density compared to other technologies. Costs are kept low by means of simplicity, compactness, modularity, atmospheric pressure operation and elevated output temperature.

newcleo is also working to significantly invest in MOX fuel manufacturing in developed countries, extracting energy from the current nuclear industry by-products.

newcleo is ready to develop a new, sustainable, and completely safe way of generating nuclear energy that will help humanity reach zero emissions and mitigate global warming.

Missions:

As part of newcleo’s ambitious Lead-cooled Fast Reactor (LFR) design and licensing programme we are looking for a Probabilistic Safety Assessment engineer to become a key player in our nuclear safety team. Our PSA professionals support the licensing programmes of both 30 MW and 200 MW LFR along with the design of a MOX fuel facility. Our PSA team is growing rapidly and provides to its members the opportunity to acquire new skills, widen their knowledge and experience by the application of advanced methods and techniques and be at the forefront of the development of new PSA methodologies applicable to the novel wave of Advanced Modular Reactors.

Your main duties and responsibilities will be:

• Develop and apply methods for probabilistic safety assessment of advanced nuclear technologies
• Build and quantify integrated probabilistic risk models including Fault Trees, Event Trees, Dynamic risk models
• Perform Human Reliability Analyses where required
• Write structured technical reports
• Present the results of the PSA work to the stakeholders and addressing any regulatory challenges
• Train and supervise junior PSA engineers

Technical & Soft Skills required:

• 5+ years of experience in Probabilistic Safety Assessments
• Proven experience with Risk Spectrum, CAFTA, SAPHIRE or similar tools
• Ability to autonomously carry out PSA work and to supervise junior engineers
• Proficiency in handling databases and programming languages (e.g., Python)
• Proven experience in writing technical reports in support of licensing

Certificates and education required:

• Relevant Science/Engineering Degree Qualified (or Equivalent) preferably in Engineering or Physics, however other technical backgrounds will also be considered.
