Title:

Lead Specialist – Radiation Physics
**** Locations:
Hybrid working with one of the following locations as your primary site:
Derby, Manchester or Warrington.
**** We anticipate paying a salary between  £57,600-£75,600 DOE.
** The Performance & Analysis team is the centre of excellence within Rolls-Royce SMR (RR SMR) for the engineering analysis used to substantiate the performance and safety of the power station. Radiation Physics and Shielding (RP&S) analysis is a key tool for supporting the design and development of the RR SMR, as we must design and substantiate radiation shielding and radiological zoning to ensure ALARP dose to workers and the public and support a broad range of other technical disciplines with inputs derived from our analysis work.

About the role:

The Lead Specialist – Radiation Physics will be responsible for the technical excellence and quality of RP&S analysis across the organisation. The role will act as the go-to technical authority for RP&S analysis, developing methodologies for complex analysis, leading teams to deliver work that aligns with technical/organisational objectives and engaging with a wide range of stakeholders. The role will involve developing the capabilities of the RP&S Team through mentorship and collaboration, supporting the strategic growth required to achieve business objectives.

The role will cultivate a culture of technical excellence, disseminating and applying best practices to the delivery, management and validation of RP&S analysis. This will include providing governance and critical review to RP&S analysis done by external partners, ensuring that all RP&S analysis used by RR SMR complies to the relevant quality and method requirements, and is ultimately fit-for-purpose. The applications of RP&S analysis to support the RR SMR are broad, with some of the key scenarios and technical disciplines this role would support being:
Radiation shielding and dose rate assessments, dose assessments for normal operations, generation of gamma and neutron flux and fluence data, Displacements per Atom (DPA) assessments, gamma heating assessments, detector response assessments, neutron activation assessments, radioactive source term generation, manipulation, and decay calculations, decay heat, burn-up and depletion calculations, support to radiological consequence calculations, support to Equipment Qualification studies (EQ), and support to radiation protection safety case activities.

Due to the safety-critical nature of the modelling we undertake, excellent quality-management processes are essential. The development of robust and automated analysis routes around the analysis codes, including clear documentation of pre/post-processing scripts (in Python) and the use of our high-performance computing resources is an important aspect of this. Additionally, the role will support the capability growth of the RP&S Team by guiding the use of analysis codes, software, licenses and hardware in line with business and strategic objectives.

As RP&S analysis supports the development and substantiation of many aspects of the power station design, effective communication and collaboration with teams across a wide range engineering and non-engineering disciplines is essential. Lead Staff should be flexible to the evolving nature of the ongoing design programme and proactive in collaborating with other teams in developing analysis requirements and communicating results. This will involve pragmatically making trade-offs between conflicting demands to ensure work streams deliver both to the required technical standard, but also in-line with time and cost expectations.

As we strive to find the best fit for this position, we are seeking individuals with a minimum level of experience, training, and qualification. But we'll let you in on a secret: there's no such thing as the ‘perfect' candidate. If you feel you meet 75% of…
