The skip handler can operate above a used-fuel storage pond.
Westinghouse UK, Middle East and Egypt vice president and managing director Dave Unsworth said: "We’ve held a framework contract at Sellafield through our involvement in Cumbria Nuclear Solutions since 2011 but this contract is our first direct contract.
"We are looking forward to working with Sellafield Ltd over the next two years to deliver a quality product that will help to facilitate accelerated clean-up and decommissioning of a high-hazard facility on the site."
Work under the contract will be performed at Westinghouse’s offices in the UK and US and is supported by Westinghouse’s global services and supply chain.
Sellafield FGMSP Programme head Martin Leafe said: "The additional skip handler machine capability is absolutely vital to successful delivery of the First Generation Magnox Storage Pond program. Westinghouse provided us with the most economical and advantageous tender. "
Westinghouse Electric Company supplies nuclear plant products and technologies to utilities throughout the world.
