Why Scotland?Scotland has a proud history of engineeringand manufacturing excellence in support ofthe nuclear energy sector and this continuestoday with significant capabilities in deliveryof the Nuclear Decommissioning Authoritysprogramme of decommissioning andclean-up of 19 civil nuclear sites across the
UK, three of which are located in Scotland:Hunterston A, Chapelcross and Dounreay.
With experience in the decommissioning of prototype Fast Breeder Reactors, Magnox
Reactors and Defence Assets, Scotland offers opportunities for development in the
delivery of new technological solutions and methods for the safe and efficient
decommissioning of nuclear facilities across both the power generation and defence
sectors.
Scotland is recognised globally for its world leading academic excellence, technical
ingenuity, and the transfer of knowledge into practical application. Scotlandsexpertise can be found in the development of solutions across engineering, technical
design, fabrication, specialist demolition and manufacturing. Scotland combines
internationally recognised research and technical expertise partnered with innovative
private companies of all sizes ready to meet the challenges of safe decommissioning
of nuclear facilities globally. It is estimated that in excess of 200 reactors will require
decommissioning globally over the next 20 years; Scottish supply chain companies are
available to share their experience and knowledge to assist other countries with delivery
of their decommissioning programmes.

Weir Group design, manufacture and supply a
range of specialist pumps specifically designed for
use with special nuclear grade sumps for handlingradioactive sludge. Weir Minerals has the ability to
custom engineer for specific customer applications
for high or low radioactive wastes.
DounreayThere were suggestions in the past that buildings like D8550 couldnever be decontaminated safely. This decommissioning project teamhas shown that even the most radiologically contaminated areas can
now be decommissioned safely and efficiently.Charlie Fowler, Dounreay
Dounreay is where some of the nations leading scientists and engineers experimented
with plutonium, uranium and other metals to furnish the UK with the knowledge to
generate electricity using a more advanced type of nuclear reactor.
After four decades of research, stretching back to the earliest days in the industry,
taking apart their legacy is a major undertaking. Today, Dounreay is a site of
construction, demolition and waste management, all of it designed to return the site to
as near as practicable its original condition.
Decommissioning Dounreay is recognised internationally as one of the most complex
nuclear clean-up challenges in the world. The skills and enterprise it fosters are giving
Scottish companies a platform to compete in the global decommissioning market.
Approximately 180 facilities were built at Dounreay. Decommissioning each facility
requires a comprehensive survey to identify every hazard, the different wastes that will
be generated and development of solutions for their management and removal. Essentialfeatures include minimising the exposure of workers to radiation, segregating and
minimising the different waste categories and disposing of these through the correct
waste management routes.
Dounreay is responsible for the delivery of a number world leading decommissioning
projects.

Removal of loose debris, draining of storage pond liquor and
decontamination of internal surfaces.
Removal of storage pond access bridge and stainless steel
liner and decontamination of concrete surfaces.
Core sampling of the bioshield and reactor vessel and
internal camera inspections.
Dounreay Shaft and Silo
A vertical shaft was built at Dounreay in the 1950s to remove rock
spoil during excavation of a subsea tunnel for the sites effluent
discharge pipes. More than 11,000 disposals of waste occurred
until 1977 when there was an explosion. By the late 1990s,
advances in technology lead to a decision to empty the shaft.
Significant achievements in the decommissioning of the shaft and
silo includeShaft Isolation Project
Construction of reinforced concrete raised working
platform
Drilling of 400 boreholes around the shaft using wire line
methods

strategy, safe systems of work documentation as
well as providing input to equipment design, plant
upgrade works and day to day problem solving.BAM Ritchies,the specialist geotechnical division
of BAM Nuttall, carried out the hydraulic isolation
of the Dounreay shaft which involved drilling using
wireline methods, the development of customisedgrout mixes for LEDT infill and rock fissure
injection using ultrafine cements creating a
nominal 10 metre thick barrier around the shaft
reducing rock mass permeability to 5x10-9 m/s.
Environmental Reclamation Services Ltd (ERS),
designed and supervised a radiological and
chemical contaminant screening exercise at the
Dounreay Waste Shaft and Low Active Drain
facilities. The exercise determined appropriate
waste management procedures for segregation,
excavation and handling radiological,
co-contaminated and chemically hazardous
arisings. ERS undertook onsite treatment of
1000m3 of non-radiological, chemically
hazardous and non-hazardous soils and 500m3
SOLA exempt hazardous and non-hazardous soils
to enable site retention. ERS offers full service
