Internal inspection of long and narrow pipework

This notice is to inform the supply chain that Sellafield Ltd is seeking a technology capable of conducting internal visual inspection of long, narrow, convoluted pipework.

Routine visual inspection of existing assets across the Sellafield site is important to understand their condition, identify any defects, and manage risk of failure.

One example of such pipework is an overflow drain line that services the Sellafield Sealines, which must be inspected every 2 years.
