Sellafield’s analytical laboratory provides analytical services to the site.

This project will re-equip and extend the existing National Nuclear Laboratory Central Laboratory to provide modern analytical facilities for the Sellafield site for several decades.

The project is currently nearing the end of the Preliminary Design phase and an optimisation project will be conducted to ensure cost, schedule and technical design aspects are optimal. The RAP project includes the provision of electrical power supplies, lighting and a range of other services, radiological containment and integration of analytical instrumentation. It is split into four workstreams, three of which are concerned with the actual analytical processes and their containment, and the fourth provides all services to the other three (balance of plant).
