Radiation Shielding

Radiation shielding is a vital component of nuclear engineering, designed to protect personnel and the public from ionising radiation. This is achieved through the use of shield walls, access labyrinths, shield doors, and service penetrations, all optimised to minimise radiation exposure. The ALARP (As Low As Reasonably Practicable) principle guides all shielding strategies to ensure safety without compromising operational efficiency.

At Cerberus Nuclear, we follow a systematic and industry-accepted shielding design process, ensuring each project is tailored to meet its unique requirements. This includes:

 • Project Commencement: Identifying shielding needs early to inform design decisions.
 • Bulk Shielding Analysis: Developing high-level configurations for preliminary shielding.
 • Detailed Design: Conducting precise modelling and simulations using state-of-the-art computational codes such as MCNP, SCALE, FLUKA, PHITS.
 • Dose-up Take Analysis: Developing a dose uptake model for a facility to ensure operator doses are ALARP.
 • Plant Modifications & Decommissioning: Supporting operational changes and safely decommissioning facilities with effective shielding strategies.
 • Shielding Verification: Validating shielding installation via shield integrity testing.

Our active role in the UK Shielding Forum underscores our commitment to industry best practices. Through the forum, we contribute to advancing shielding standards and providing authoritative guidance across the sector.
