Process Engineer - Carbon Capture

Process Engineer – Carbon Capture (Nuclear Sector)

The Process Engineer – Carbon Capture (Nuclear Sector) is responsible for the design, assessment, and optimisation of carbon capture processes associated with nuclear-enabled decarbonisation projects. This includes integration of carbon capture systems with nuclear power plants, SMRs, advanced reactors, and nuclear-supported industrial facilities (e.g. hydrogen, synthetic fuels, district heat, industrial CCS). The role operates within a highly regulated nuclear environment
, ensuring compliance with nuclear safety, quality, and assurance requirements.

• Process Engineering & Design:
  Develop process designs for CO₂ capture, conditioning, compression, and purification systems linked to nuclear facilities or nuclear-supported industrial processes.
• Produce and review PFDs, P&IDs, heat and material balances
  , and process calculations.
• Perform steady-state and dynamic simulations using recognised process modelling tools (e.g. Aspen Plus, Aspen HYSYS).
• Support selection and adaptation of capture technologies (amine-based, advanced solvents, membranes, hybrid systems) suitable for nuclear integration.

• Assess and manage interfaces between nuclear systems and balance-of-plant (BoP) carbon capture facilities.
• Support integration with SMRs or advanced reactors providing low-carbon electricity and/or heat to CCS or CCUS processes.
• Ensure process designs align with nuclear operational constraints, availability targets, and outage philosophies.

• Apply nuclear safety culture
  , quality assurance, and configuration management principles to process engineering activities.
• Support HAZID, HAZOP, ALARP assessments
  , and nuclear safety case inputs where required.
• Ensure compliance with nuclear regulations, environmental permitting, and international standards (e.g. ONR, IAEA, ISO, ASME as applicable).
• Prepare and review process documentation suitable for regulatory submission and audit
  .

• Contribute to concept, feasibility, pre-FEED, FEED, and detailed design phases within nuclear project frameworks.
• Provide technical input to CAPEX/OPEX estimates
  , schedules, and risk registers.
• Support technology maturity assessments (TRL) and demonstration project development.

• Support commissioning, start-up, and performance testing of CCS systems associated with nuclear facilities.
• Assist with operability, maintainability, and lifecycle optimisation
  , including long-term nuclear plant operation considerations.
• Contribute to continuous improvement and lessons-learned processes.

• Degree (BSc, MSc, or equivalent) in Chemical Engineering, Process Engineering
  , or a closely related discipline.

• Typically 5–12+ years of relevant process engineering experience (level dependent).
• Experience working on nuclear, highly regulated energy, or safety-critical infrastructure projects
  .
• Practical experience with carbon capture, gas processing, or separation technologies
  .

• Strong grounding in thermodynamics, mass transfer, heat transfer, and process control
  .
• Proficiency in process simulation and design tools
  .
• Understanding of nuclear project life cycles
  , safety case development, and quality assurance processes.
• Familiarity with CO₂ compression, dehydration, and export systems is advantageous.
• Strong commitment to nuclear safety culture and procedural compliance.
• Ability to operate effectively in multi-disciplinary nuclear project teams
  .
• High standard of technical documentation and traceability.
• Clear, structured technical communication with regulators and stakeholders.

• Nuclear-grade process calculations and simulations
• PFDs, P&IDs, and interface documentation
• Safety study inputs and regulatory-ready process descriptions
• Technical contributions to nuclear design substantiation and assurance processes
