Cavendish Nuclear shares modular experience at Sellafield event

Cavendish Nuclear, part of the UK’s leading engineering services business, today shared its knowledge and experience of modular design and construction with an audience of professionals from Sellafield.

Modular Build 2018, a half-day conference held at the Hinton House offices of Sellafield Ltd at Birchwood, brought together more than 70 engineers and project managers representing some of the world’s largest nuclear clean-up projects.

They heard how innovation in modular techniques has the potential to deliver clean-up work faster, safer and at lower cost.

The event was organised by Sellafield Ltd and the Design Services Alliance (DSA), which provides Sellafield Ltd with access to major contractors operating across the supply chain to the UK nuclear industry.

Alan Cummings, director of operations at the Nuclear Decommissioning Authority, gave the keynote address.

Cavendish Nuclear and our parent company were delighted to be able to share our experience in this sector with DSA colleagues from Sellafield Ltd.

Paul Smith, Director Nuclear Services

Cavendish Nuclear and its parent company, Babcock International Group, both gave presentations at the event.

Babcock International Group outlined its experience of modular construction at Rosyth in Fife, Scotland, including the assembly of the Queen Elizabeth class of aircraft carriers and infrastructure for Terminal 5 at Heathrow.

The facilities at Rosyth allow for large-scale assembly and testing of critical infrastructure before they are delivered to the customer in a ready-to-use state.

Six primary nuclear containment doors, each weighing approximately 13 tonnes, were manufactured and tested at the facility before being delivered to Sellafield for the Pile Fuel Cladding Silo (PFCS) decommissioning project last year. The next phase of modular work – the assembly and testing of the remotely-operated retrievals and operational training rig that replicates the silo and penetrations – is now underway at Rosyth.

Cavendish Nuclear also outlined the capabilities of its production facility at Whetstone, Leicestershire, where a series of modular facilities, using similar tried-and-tested techniques deployed on PFCS for the retrieval of radioactive waste from underground vaults, were assembled and tested prior to installation at the former nuclear power station at Berkeley in Gloucestershire.

Paul Smith, director of nuclear services at Cavendish Nuclear said:

“Off-site modular construction and testing significantly reduces the risks during installation and commissioning in hazardous areas and can deliver safer, faster and more cost-effective clean-up and remediation of redundant nuclear plant.”

“Cavendish Nuclear and our parent company were delighted to be able to share our experience in this sector with DSA colleagues from Sellafield Ltd.”
