Nuclear Decommissioning Agency Mission Progress Report 2021
5th November 2021
This is the latest iteration of the Mission Progress Report (MPR) which focuses on the key themes that form the milestones by which we will deliver our mission across our nuclear sites.
In this report, our progress and goals have been aligned with those in our latest Strategy, published in March 2021, allowing for a more consistent approach to presenting our decommissioning mission.
"We are always looking at a changing picture as the uncertainty surrounding our inventory reduces and we further develop our strategy. It is however, becoming increasingly accurate as we share learning across the group and work closer together on numerous projects."

DSRL, the University of the Highlands and Islands and the Nuclear Decommissioning Authority (NDA) have collaborated to develop an innovation workshop for some of Dounreay's future talent. Dounreay was a former nuclear research centre for 50 years, and now wishes to trial innovative ideas as it decommissions, by challenging conventional methods and bringing in ideas from other industries.
DSRL is funding research through the University of the Highlands and Islands for a critical PhD project to model the behaviour of legacy radioactive particles in the marine environment at Dounreay. An important part of the work to close down Dounreay is to address the legacy of the radioactive particles that wash up on the beaches next to the site.
The first roof beams have been lifted into place at Dounreay's newest shielded radioactive waste store. Seventy six beams, weighing a total of 1,400 tonnes, the equivalent of 116 double decker buses, are needed to complete the mammoth roof structure which will have a total weight of 3,300 tonnes.
Six new decommissioning operative trainees have started work at Dounreay, as part of a structured programme to develop skills required to safely decommission the site. DSRL is collaborating with Nuvia, Morson and GDES who have all recruited trainees.
Innovation in the face of adversity earned Scotland's largest nuclear site a shot at Scotland's top event award. About 100 or so workers normally attend Dounreay's annual showcase event, when staff are recognised for reaching levels of excellence in their work to decommission the plant.
Dounreay Site Restoration Limited (DSRL) has awarded two contracts worth a combined GBP11.2 million (USD15.9 million) to USA-based engineering group Jacobs for decommissioning work at the Dounreay site in Scotland. Under the contracts, Jacobs will upgrade the ventilation system at the Prototype Fast Reactor (PFR) and develop the decommissioning strategy for the fast reactor fuel reprocessing plant in the Fuel Cycle Area.
The shaft and silo project ‘advanced transition' work is getting underway at Dounreay. Radioactive waste was historically consigned to the 65 metre deep shaft and the silo, an underground waste storage vault, over several decades starting in the late 1950s.
Airline suit work has restarted at Dounreay after more than a year's delay caused by the COVID-19 pandemic. Wearing an airline suit is cumbersome and the wearer needs to be dressed and undressed by a dedicated team of helpers who then provide support throughout the task.
Ground-breaking research published in Nature Communications shows that traces of plutonium in the environment can be identified as being from global or local sources. Using soil samples taken from Dounreay, an area near to the site and 2 areas at a distance from the site, the research showed that it was possible to identify whether minute traces of plutonium in the soil came from plutonium ‘bred' in a reactor or from global fallout.
Statement issue18 March 2021 by NDA, Dounreay and Sellafield. In 2013 we concluded the development of our strategy to remove unirradiated nuclear material from Dounreay and consolidate it at Sellafield.
