The Radiation Physics & Shielding team:

Are you looking for opportunities to progress your career in science and engineering? Would you like to lead specialist engineering and physics activities? Would you enjoy doing this whilst also working on the most complex engineering project on the planet? If the answer to any of those is yes, then we want to hear from you.

The Radiation Physics & Shielding department is responsible for the design and validation of radiation shielding for the UK's nuclear powered submarine fleet. We are engaged across three different submarine programmes in different stages of the engineering lifecycle designing new shields, providing design change assessment into the build programme and conducting radiation metrology on-board during commissioning.
