The 3,000 m³ material is stored at the south end of the spit. Ano t he r cha l l enge wa s c ro s s i ng t he r i ve r, an environmentally sensitve area. The bridge put in place is a single span (to minimise the impact on the River Ehen) with piled foundatons. The bridge deck is precast concrete slabs supported on four large beams (38 m in length, each 2 m wide with a 2 m deep).

Bill Condon, Director, Project Management, Nuclear Management Partners said: “This is the first time in the history of the Sellafield site that barge delivery has been used to transport large equipment to the site. It has been a real team efort and I would like to thank everyone involved in the project. They have all contributed to a fantastc job”. Mark Steele, Nuclear Decommissioning Authority’s Deputy Head of Programme for Sel laf ield said:” The Evaporator D project has been and remains extremely challenging and the delivery of the frst two modules to site and subsequent installaton marks signifcant progress. The organisations involved demonstrated their professionalism and worked well together to land the modules. We look forward to further deliveries in the coming months”.

The deci s ion to use the innovat ive technique of modularisaton was made at an early stage in the life of the project; following the recogniton that modularisaton would bring numerous benefts.

These include enabling fabrication and testing of the majority of the plant equipment of-site within a workshop environment (as opposed to on-site), improving Quality Assurance, reducing constraints associated with on-site testing and the requirement for high risk tasks, such as working at height, being substantally reduced.

Work on the Evaporator D project is due to be completed in 2014. It will provide additional capacity to support the site’s existng evaporators, which contnue to play a pivotal role in the delivery of nuclear fuel reprocessing contracts and in maximising the reducton of risk to the public and the environment from site operatons.

. . .and the future is good with contracts for new waste retrieval facility

Decommissioning progress on one of Sellafield’s oldest nuclear plants has taken a giant step forward with three signifcant new contracts, totalling over £160 million, put in place to enable radioactve waste retrievals.

The Pile Fuel Cladding Silo (PFCS) is almost 60 years old and contains historic radioactive waste, which has to be retrieved from the facility as part of the decommissioning work. The three contracts will be for the following:

• Silos Retrieval Facility superstructure - £8 million with Sir Robert McAlpine • Waste Retrieval Modules - £150 million with Bechtel Babcock Nuclear Services • Semi Goliath Crane - £3 million with Clarke Chapman Group

Tim Davies, Head of PFCS Retrieval Projects said: “Sellafield Ltd has let these contracts in order to deliver an accelerated decommissioning programme that we have committed to and agreed with our customer, the Nuclear Decommissioning Authority (NDA).

“This is a hugely significant step forward for the programme and represents the start of a new collaborative partnership towards waste retrieval and ultmate hazard reducton. We’re pulling out all the stops to drive forward this project by bringing in specialist contractors.
