About the role
We are seeking a Senior Radiometric Physicist to take a leading role within our Radiometric Systems Group (RSG) Characterisation team providing specialist radiometric nuclear physics support across a range of Radiometric Characterisation Projects and to Nuclear Material Assay (NMA) operations across the site.
The role will support radiometric characterisation services in decommissioning, waste management and operations. This involves the deployment of portable specialist radiometric assay equipment in-situ in our legacy and operational facilities. The role will also involve providing Intelligent Customer oversight to supply chain-led tasks and projects where radiometric characterisation is provided.
The role will also support innovation; research and development; and Technology deployment tasks, to ensure that Sellafield Ltd and the Nuclear Decommissioning Authority has the tools and techniques it needs to achieve its mission.
Nuclear Material Accountancy systems provide accurate measurement and quantification of radioactive materials in operational facilities and utilise a wide range of radiometric physics techniques. These systems are essential to safe and secure operations.
This role will appeal to someone with in-depth radiometric knowledge or a technical specialist currently working in a radiometric leadership role. You\’ll have knowledge of a wide range of radiometric physics techniques such as Gamma, Dose and Neutron measurements, and ideally experience of applying your radiometric expertise to support the delivery of radiometric characterisation projects. Some knowledge of Nuclear Material Assay equipment and technology development would also be advantageous.
Key responsibilities:
• Provide the appropriate specialist physics knowledge required to deliver all technical elements of the project to appropriate quality requirements.
• Lead project delivery and provide technical oversight of team activities to ensure delivery within safety, quality, time and cost constraints.
• Provide specialist radiometric physics knowledge to allow the most appropriate radiometric characterisation solution to be determined.
• Develop detailed task specifications, calibration philosophies and measurement plans and ensure that specialist equipment has been appropriately calibrated and tested to confirm satisfactory performance.
• Perform detailed data analysis and interpretation of acquired radiometric data.
• Produce technical reports and perform independent check of technical reports produced by other radiometric physics personnel.
• Deliver an IC assurance role to ensure radiometric physics work scope (technical reports, spreadsheets and mathematical models) delivered by contractors are technically correct and delivered to the appropriate levels of safety and quality.
• Provide radiometric physics support to nominated Sellafield operating facilities to ensure continued satisfactory operation of their NMA assay systems.
• Ensure that NMA systems have been appropriately calibrated and tested to confirm satisfactory performance.
• Provide radiometric physics support to the investigation of NMA operational issues and equipment failures.
• Provide radiometric physics support to the introduction of new NMA equipment to the Sellafield site. This support is normally provided during the specification, development, testing and commissioning phases for new instrumentation.
• Provide expert radiometric physics advice to characterisation technology development projects.
• Review new emerging characterisation techniques/technologies. Support SL Active Demonstrator projects which utilise radiometric equipment or techniques.
Your skills and qualifications:
• A degree in Physics or a related STEM discipline.
• Strong analytical skills that can be used to analyse complex data sets using commercially available software tools and self-developed mathematical models/spreadsheets.
• Excellent technical report writing skills.
• Strong customer facing skills with the ability to communicate technical work scope verbally in a confident and authoritative manner to a range of stakeholders at all levels.
• Good team working and interpersonal networking skills.
• Able to specify and manage technical work scope delivered by a subcontractor.
