In October 2015, LLWR submitted a major planning application that, if granted, would secure the site’s future for decades to come.

While the issuing of a new Environmental Permit had been a huge step forward for the organisation, planning permission was also required for disposal to continue in the long term.

The planning application sought to enable the phased construction of an extension to Vault 9 – 9a – and two new vaults, 10 and 11, where low level waste would be disposed of in specially-grouted containers.

The application would also allow higher stacking of containers in Vault 8 and the disposal of containers in Vault 9, where they could currently only be stored.

In addition, it would permit the construction of a final cap over existing and new vaults and seven landfill-style trenches where waste was disposed of prior to the opening of the site’s first vault in 1988.

The final cap would ensure the site was progressively restored to grassland with screening planting on the site perimeter.

Consent was granted in July 2016, and work could start in 2017. The project is expected to create around 120 full-time construction jobs over its lifetime.

Initially, tree screening along the northern, eastern and western boundaries of the LLWR site will be removed, exposing views of the first phase of the landscape cap, until formation of a ‘cap shoulder’.

The shoulder, four to five metres in height, will provide screening, and higher stacking of containers would not take place until this phase of the cap was in place.

Granting of the application ensured the site’s future until around 2050.

But LLWR plans to accommodate the UK’s forecasted low level waste arisings well into the next century, potentially constructing more vaults, of required, and subject to securing the necessary permission and consents, with a closure date of around 2130.
