Position: Environmental Engineer - Stack Monitoring

Location: Client Office at Culham - Hybrid working: 2 days per week office attendance.

Arrangement: Contract (Inside IR35) or Permanent basis. 

NUVIA UK's Technical Services & Consulting department is fast growing with hybrid opportunities available up and down the country. We're striving to create a multidisciplinary team to offer our clients the best range of talent.

BPSS clearance will be required at basic level. Prior clearance will not be transferable.

Purpose of the Role:

The role is required to lead the evaluation and development of stack monitoring strategies for UKAEA facilities, ensuring compliance with environmental and radiological regulations, and assessing the feasibility of establishing in-house monitoring capabilities. This role will deliver two key studies:

• D1: Stack Monitoring Feasibility Study
• D2: In-House Stack Monitoring Capability Study

Key Responsibilities:

• Conduct a comprehensive review of historical stack monitoring data, including tritium, radiological, and beryllium measurements.
• Analyse operational trends and bubbler water contamination patterns; assess impact on measurement accuracy.
• Evaluate Safety Case requirements and compliance obligations (i.e. Best Available Techniques (BAT) Assessments) for stack emissions.
• Define data requirements for Environment Agency (EA) submissions and ensure regulatory alignment.
• Audit existing stack monitoring processes.
• Assess feasibility of developing in-house stack monitoring capability.
• Prepare detailed reports with recommendations which ensure adherence to UK regulations (EPR, IRR17, Beryllium (COSHH)), EA guidance, and ALARA principles.
• Incorporate radiological and hazardous material safety considerations (tritium, beryllium) into all assessments.
• Maintain robust risk management and contamination control measures.
• Liaise with internal stakeholders (Health Physics, Safety, Environmental, Operations).
• Communicate findings and recommendations clearly to senior management and technical committees.
• Produce high-quality technical reports and supporting documentation.
• Apply QA/QC standards to all data analysis and reporting activities.

Degree-level education in:

• Environmental Engineering
• Chemical Engineering
• Environmental Science or Air Quality Management

Relevant certifications, such as:

• MCERTS (UK) for stack emissions testing, or emissions monitoring.
• Radiation Protection Supervisor (RPS) or equivalent ISO 17025 awareness for analytical labs

Safety training:

• Radiological safety and ALARA principles (Desirable but not essential)
• Handling beryllium (Be) and toxic metals
• PPE and contamination control

Radiological principles:

• Tritium behaviour in gaseous and water vapor forms
• Decay, dispersion, and dose modelling

Beryllium hazards:

• Toxicology, occupational exposure limits, and monitoring techniques

Regulatory frameworks:

• IRR17
• EPR
• COMAH (Control of Major Accident Hazards regulations)

Monitoring technologies:

• Tritium monitors (ionization chambers, proportional counters)
• Beryllium sampling and lab analysis

Environmental impact assessment:

• Radiological dispersion modelling
• Stack emission modelling for hazardous substances

Experience:

• Data analysis and reporting: Interpreting emission data, QA/QC procedures, uncertainty analysis.
• Stack sampling and monitoring: Manual and CEMS techniques for conventional pollutants.
• Radiological monitoring: Tritium sampling (HT, HTO) in air and stack emissions
• Use of liquid scintillation counters, ion chambers, and tritium monitors.
• Hazardous material handling: Beryllium sampling and analysis.
• Data interpretation: Radiological dose assessment and emission factor development for radioactive and toxic substances.

Employee Staff Benefits:

• 8.5% Pension Contribution & Life Assurance
• Private Medical Scheme*
• Employee Share Scheme
• Salary Sacrifice Schemes: Electrical Vehicles, Technology and Cycle to Work
• 18 Weeks Full Maternity Pay* (+21w SMP)
• 25 days holiday (increasing to 28 days after 5 years’ service, 31 days after 10 years’ service)
• Option to buy, sell and carry over up to 5 days annual leave per year
• In partnership with trade unions
• Personal Development & Further Education Support
• Long Service & Recognition Awards
• Free Employee Assistance Programme
