Have you ever wondered what we do? Let us explain.
Here at Sellafield Ltd, our world-class employees solve complex nuclear, engineering, and infrastructure challenges for the UK every single day.
In operating, developing, and decommissioning the Sellafield site, we are also delivering one of the largest environmental restoration projects in Europe.
What sort of work does that include? Find out more below 👇

On this day 70 years ago, Queen Elizabeth II arrived at Calder Hall to open the world's first commercial power station to supply domestic electricity.
Its success ushered a new era of clean energy and placed us at the centre of the UK's nuclear industry.
#Sellafield #Nuclear
Calder Hall turns 70 today!
Here’s to the generations of people whose work built its legacy, and whose expertise will shape our future.
#Sellafield #Nuclear
In 1956, the UK made history with the world’s first commercial civil nuclear power station.
We’re celebrating the people behind 70 years of nuclear power.
From the generations who built the industry to the workers and apprentices shaping its future 🎥

#ThrowbackThursday: The birth of a legend
70 years ago this week, Calder Hall was preparing to open.
These photographs capture the people, engineering and ambition behind a project that helped shape West Cumbria's nuclear story.

One of the original liquor storage tanks being installed at Sellafield.
Now those same tanks have been safely emptied, helping reduce risk and prepare the facility for the future.
A huge thank you to everyone involved!

📣 PACE is here.
Working with OneAxIoM and HOCHTIEF Infrastructure UK, our new framework could deliver up to £3.6bn of asset care work at Sellafield over the next 15 years, supporting our mission, jobs and local communities.

A rare archive photo of the #Sellafield site that we don't think has been seen for many years! The Pile Fuel Cladding Silo appears to be the only building on this section of Windscale land, showing just how much the site has changed.
Guess the year below 👇
Great to see The Old Bank become the first project completed through the #MillomTownDeal.
Supported by Sellafield SiX programme, this restored heritage building will create new opportunities for businesses and visitors.

Innovation has always been part of our story.
This archive pic from the 1960s shows Percy Gill, George Buckley and Bill Robertson with one of their inventions, proving that problem-solving has long been helping to tackle challenges across Sellafield.

Before Sellafield's nuclear story began, the site supported the WWII war effort as the Royal Ordnance Factory producing TNT. By 1947, it was entering Britain's atomic age.

Do you have any memories or family connections?
At first glance, it's just a grey concrete box.
Not exactly the most eye-catching photo in your feed ahead of a bank holiday…
But these prototype containers - made of fibre-reinforced concrete - are helping our teams explore potential future storage solutions for the intermediate-level waste we generate across the Sellafield site.
Our priority is to manage this waste safely and securely. That’s why we continue to invest in research and development in this area. It means we can identify opportunities to improve how we deliver this national capability for the long term.
With around 60,000 intermediate-level waste storage boxes expected to be needed across our mission, even small improvements in design and manufacturing could make a big difference in the years ahead.
Sometimes the future doesn't look flashy. It just looks like a concrete box.

This week, we're looking back at the opening of Seascale Primary School in West Cumbria.
Opened by Sir Christopher Hinton during the Windscale era, the school was built as the local community grew alongside the UK's developing nuclear industry.
🏢 His legacy lives on today, with our Warrington office named in his honour.
🤔 Can you guess what year this photo was taken?

What happens after we retrieve waste from our legacy ponds and silos? This #FutureFriday is about just that.
Retrieving waste is just the first step in the clean-up of our legacy ponds and silos. We then need to ensure this waste can be treated, packaged and stored safely.
To make this possible, we often need to build new infrastructure.
The Box Encapsulation Plant Product Store 2 (BEPPS2) is the latest intermediate-level waste store under construction on the Sellafield site.
Delivered by the Programme and Project Partners (PPP), we recently reached a major construction milestone with the first concrete pour for the future store.
Once operational, BEPPS2 will provide vital storage capacity for waste packages produced as we continue to empty our legacy ponds and silos.
Together with the Box Encapsulation Plant, it will ensure waste retrieved from these high-hazard facilities can be safely managed until a Geological Disposal Facility becomes available.

This is Pond 4 before there was any water in it.
Before it became a fuel storage pond, teams had to prepare and clean the huge concrete structure ready for commissioning.
Unlike the historic open-air ponds many people associate with Sellafield, Pond 4 was designed as a modern, covered facility to safely store and cool spent fuel before reprocessing.
Do you remember working on Pond 4? Share your memories 👇

🚀 We were delighted to welcome local MP @JoshMacAlister to Sellafield yesterday.
Colleagues showcased the work they're doing to keep the site safe and secure today, while building the skills and expertise needed for future missions.
Josh also met some of our #WaveAwards nominees and winners, celebrating the people making a real difference across our business.
Thanks to everyone who shared their work and experiences. Together, we're helping shape the future of Sellafield.

👀 A bird's-eye view of Sellafield from the top of a Thorp stack.
This photo is a real snapshot in time, with plenty of clues hidden in the construction work and changing skyline.
Think you can work out when it was taken?
📅 What's your guess?

This image from the 1960s, taken for the UK Atomic Energy Authority (UKAEA), is a reminder that Sellafield has been part of the UK's nuclear story for almost 80 years.
The lorry and sign might look very different by today's standards, but one thing hasn't changed. For generations, people at Sellafield have worked to manage nuclear waste safely and help protect the environment.
While we can't pinpoint the exact location, it's almost certainly an area that has since become part of the UK's Low Level Waste Repository, operated by Nuclear Waste Services.
💡 Did you know? Sellafield is the only site in the UK that can process, treat and store every type of nuclear waste.
❓ Any guesses on the exact year this photo was taken?

How can we drive robotics innovation through collaboration?
We recently welcomed government and regulator representatives, including Lord Willetts, Chair of the Regulatory Innovation Office, to the Sellafield site to explore that question.
Visitors saw first-hand how we are using advanced robotics to help tackle some of the UK's most complex decommissioning challenges. This included SPOT the quadruped robot and remotely operated vehicles (ROVs) carrying out clean up activities, followed by a visit to the off-site Robotics and Artificial Intelligence Collaboration (RAICo) facility to see how collaborative working is helping to bring new technologies into the nuclear sector.
The visit highlighted the role industry, government, academia and regulators can play in enabling innovation as well as the opportunities robotics offers to accelerate progress across the UK's nuclear industry.
