Join Holtec Britain, a member of the Holtec International family; a global leader in designing an unconditionally safe and secure source of clean energy. Holtec has received funding from the FNEF to advance its SMR programme, and is building its brand new team based in Bristol.
The Radiation Shielding Engineer will be responsible for developing comprehensive shielding models using MCNP6.2 to evaluate radiation levels from various sources within the plant, including the reactor pressure vessel, spent fuel pool cooling system components, radwaste systems, and other critical areas. The analysis will encompass normal, startup, shutdown, and refueling operations. Microshield will be used for preliminary scoping studies as needed. You will also contribute to the drafting of PSR/PSAR sections related to shielding analysis, ensuring that the plant design meets regulatory requirements and maintains public safety.
Specific areas of focus will include:
* Reactor Pressure Vessel: Neutron fluence, ex-core detector responses, and RPV activation.
* Spent Fuel Pool: Shielding analysis for the cooling system components, including heat exchangers and demineralizers, during both normal operation and refueling.
* Radwaste Systems: Shielding assessments for liquid, solid, and gaseous radwaste components, including filter transfer casks, pumps, holding tanks, spent resin tanks, dropout tanks, gas decay tanks, and compressors.
* Main Control Room: Evaluation of radiation shielding effectiveness to protect operators.
* Airborne Radiation: Assessment of radiation levels in open areas, corridors, and controlled areas, including those near the containment vessel, spent fuel pool, and radwaste systems.
* PSR Drafting: Contribution to the preparation of PSR sections related to shielding analysis, ensuring that the plant design complies with regulatory requirements and provides adequate protection against radiation exposure.
* Improvement of working processes and procedures.
* Manage working time, working autonomously.
* Make decisions and recommendations within authorised limits. Exercise considerable judgement and initiative in interpreting policy in the planning and implementation of projects and/or work assignments.
Minimum Requirements:
* Degree qualified in an engineering or science related discipline.
* Demonstrated experience and proficiency with radiation source term, shielding and radiological-consequence dose assessment tools, e.g., MCNP, SCALE, GALE, ARCON96, RADTRAD or other applicable analysis code packages.
* Demonstrated experience and proficiency in performing radiological release and transport calculation to evaluate dose to worker and public.
* Experience with computer languages such as Python.
* Eligible to work under 10 CFR Part 810.
