The £100 million Silo Emptying Plant will scoop radioactive waste out of the Magnox Swarf Storage Silo.

The 1960s storage facility has been described as one of the most hazardous buildings in western Europe and contains 10,000 cubic metres of intermediate level waste from the earliest days of the UK’s civil nuclear industry.

John Clarke, outgoing NDA Chief Executive, unveiled the machine – the first of three being assembled in the building – at a ceremony yesterday.

He said:

This is an enormous step forward for the Sellafield decommissioning programme.

It is the culmination of 20 years of work to get to the position where we’ve got the first machine in place that will retrieve waste from these silos.

The machines will sit on rails on top of the silo’s 22 vertical waste compartments. Each compartment is big enough to accommodate six double decker buses stacked three high.

Once operational, the emptying machines will be manoeuvred into place over the top of each compartment to scoop out their contents.

The material will then be packed into nuclear skips and sent to modern waste stores at Sellafield, pending final disposal in the UK’s Geological Disposal Facility.

The machines will be ready to start retrieving waste in 2018, taking an estimated 20-25 years to complete the task.

Chris Halliwell, head of the Magnox Swarf Storage Silo, said:

This is probably the most complicated and advanced machine ever built at Sellafield.

It has about 13,500 different working parts and its design and concept was first drawn up more than 20 years ago.

Turning that vision into the machine we have today has been a major challenge for the UK’s advanced manufacturing and nuclear supply chain.

The process has been hugely challenging because no plans were drawn up for how waste would be taken out of the building when it was built in the 1960s.

The emptying machines were built by engineering firm NES Ansaldo at its Wolverhampton factory, before being dismantled and sent to Sellafield in 23 separate modules.

These modules were lifted one by one into the silo building and then re-assembled in situ.

Chris Halliwell added:

There is no job at Sellafield more important than the one being done by this machine. Emptying the waste from this legacy silo is our number one priority.

It has to be reliable because once it starts taking waste out, the contamination inside it would make it very difficult to maintain or repair.

The silo took waste from nuclear power stations all over the UK until its closure in June 2000.

Its contents are chiefly made up of magnesium cladding which was stripped from nuclear fuel rods before they were sent for reprocessing.

The Environment Agency publish permits that they issue under the Industrial Emissions Directive (IED).

What is the Rural Payments service?

The Rural Payments service is Defra’s online registration system for farmers, animal keepers and rural traders and businesses.

They can use it to register their details, see and update digital maps of their land and make online applications for certain rural grants and payments.

It can be used by any person or firm representing a farmer or farming business – such as a firm of agricultural agents.

Throughout the Rural Payments service, there is onscreen guidance which explains how to use it.

You must register on the Rural Payments service if you intend to keep farmed animals (or livestock) on your land or business premises.

Data on waste management are collected in order to monitor progress towards national and local targets; in particular against the requirements of the EU Landfill Directive.

The Environment Agency is continuing conservation measures on its Watersmeet and Glenthorne Fishery for the coming season.

Restrictions have been in place on this popular Exmoor fishery since 2014 in response to disease problems affecting adult salmon and sea trout returning to the East Lyn to spawn. Recent monitoring also revealed reduced numbers of young salmon.

Anglers have been allowed to continue fishing for salmon and sea trout on a ‘catch and release’ basis throughout the season and have been limited to fishing with a fly or spinner only. The use of worms was traditionally allowed from 16 June. However, this method of fishing can be very effective and has been prohibited in recent years to limit the number of fish caught while stocks have been under pressure.

Following discussions with the Lyn Riparian Owners Association and local interest groups, worming is being allowed again on a trial basis this year from 16 June, subject to strict conditions.

Worms will only be allowed when fished on a single circle-patterned hook, no larger than Size 4. A circle hook increases the likelihood a fish is hooked in the jaw where it can be safely removed. This type of hook reduces the risk of ‘deep hooking’ which can sometimes occur when worming. It also reduces the chances of accidentally catching trout and salmon parr on this method.

All salmon and sea trout must still be released throughout the 2017 season, irrespective of the method used to catch them. As a further conservation measure, anglers will not be allowed to fish with worm at any time in Long Pool.

Mike Holland of the Environment Agency said:

We want fishermen to continue to enjoy their sport on the Watersmeet and Glenthorne Fishery, but at the same time ensure suitable measures are in place to safeguard migratory fish returning to the river to spawn.

By allowing only circle hooks to be used for worming we hope to maximise the survival chances of any salmon and sea trout caught and released by this method. We’ll review the success of this trial at the end of the season.

The brown trout fishery regulations remain unchanged. The full list of fishery regulations can be found printed on the reverse of the permits, purchasable from local agents.
