Sellafield SMF declared ‘ready for action’

Servelec Controls delivers a complete control and safety system for the award winning Silo Maintenance Facility project

  • Friday, March 29, 2019

A vital new Silo Maintenance Facility (SMF) at Sellafield has been officially declared ‘ready for action’. And with the new Nuclear Facility ready to tackle legacy wastes, Servelec Controls is pleased to share the details of its part in the award winning project.

Working on behalf of the SMF Delivery Team (SMFDT) comprised of Cavendish Nuclear and Balfour Beatty JV, Servelec Controls designed, manufactured, tested and delivered the complete control and safety system for the SMF.

The impressive new facility, which has been eight years in the making, will allow Sellafield to empty waste from its legacy Silos, a major priority for the nuclear fuel reprocessing and nuclear decommissioning site.

Servelec Controls’ complex multi-subsystem control solution for the new facility integrates monitoring, control and analysis of multiple plant areas and related processes, including:

Local and remote control of all the operations inside the SMF

Flask loading and maintenance

Package collection

Package and shield door operation

The import and export of components inside package skips

Decontamination, wash-down and effluence collection and sentencing

Bogie maintenance
