Hazardex 2019 Conference Presentations - Decommissioning at Sellafield - Implications for Control & Instrumentation

Author : Tom Nobes - Process Instruments Capability Leader, Sellafield

19 November 2018

The Nuclear Decommissioning Authority owns several site-license companies in the UK. One of them is Sellafield Sites Ltd®. Sellafields’ traditional role of reprocessing spent nuclear fuel will cease in 2021. The respective plants then enter POCO (Post Operations Clean Out), decommissioning and waste management. Sellafield is also actively seeking new missions.

But what will all this mean for control & instrumentation? What new measurement techniques and information technologies will be required?


Thomas S. Nobes is Principal Engineer, Process Instruments, Sellafield Ltd. He is a Chartered Engineer and a Fellow of Engineering with the Institute of Measurement & Control.

He is Capability Leader for Process Instruments at Sellafield, effectively an internal consultant, owner of the company standards and procedures for process instrument design and is a design auditor for safety assesments. A large part of his role is the promotion and introduction of new technologies within Sellafield. These have included HART, FieldBus, ISA100Wireless and asset management. His latest thoughts are on the Internet Of Things and it’s application to nuclear decommissioning.

He is a local section committee member for the Institute of Measurement & Control and a national member of its Standards Policy Panel for instrumentation.
