The waste, which was generated while the site was operational, is safely stored inside a self-shielded cast iron container.
Steve McNally, Site Director said: “This is a huge achievement for the site and a fitting end to a successful year. It’s a great reward for the effort and dedication the team has shown and provides momentum for a new year of safe delivery.”
The ISF at Berkeley is the largest of its kind in the UK, with a footprint the size of a football pitch. Once decommissioning is complete it will hold around 850 waste packages from Berkeley where they will be held in interim storage until a national disposal facility becomes available.
Dr Brian Burnett, Head of Programmes at the Nuclear Decommissioning Authority (NDA), which owns Berkeley site, said: “In 2010, Berkeley was the first Magnox site to place its two reactors into safestore. The focus now is on retrieving, packaging and storing the waste on site to enable Berkeley to enter care and maintenance. This is an important step on that path and I commend Magnox on its achievements.”
The decommissioning programme at Berkeley is well under way and each box of waste that is retrieved and stored in the ISF is a step closer to care and maintenance, which is expected in 2021.
