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.

GSE Systems Power Station Simulator Suite, The

GSE Systems Power Station Simulator Suite is a

2M facility which provides a high-fidelity

simulation of the control room within a range of

generating stations. Configurable to cover a wide

range of generation technologies, including

combined cycle gas turbine and nuclear

generation, it provides users with an immersive

experience of operating a power station.

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.

The reactor dismantling project is critical to theNuclear Decommissioning Authoritys site

restoration plan for Dounreay. The expertise within our highly skilledin-house design team is invaluable to the PFR project delivery

and innovative inventions like Reactorsaurus isone of the reasons Dounreay is leading the way

with worldwide nuclear decommissioning.

Dounreay Materials Test Reactor (DMTR)

Dounreays Materials Test Reactor was the first operational

reactor in Scotland. It was constructed to test the effect of nuclear

irradiation on different materials.

Significant achievements in the decommissioning of the DMTR

include

Removal of fuel storage racks from the fuel storage pond andconsignment as waste.

Baseline radiological survey of pond and surrounding area.

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

Grouting of boreholes to seal fissures in rock using

micro-fine cements and nano-silicates

Isolation curtain completed in 2008

Initial concept design and VR simulation of Shaft intervention

Platform completed.

Trials completed with 2 & 4 shaft waste shredder machines.

Proof of concept trials for Solid-Sludge separation facility

completed and mock-up installed.

Prototype system for bin filling and lidding manufactured for

mock-up testing.

Waste passivation system mock-up developed.

Nuclear Decommissioning Services Ltd (NDSL),

provided project engineering support to the

implementation of the pond decommissioning

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

Geo-Environmental Investigation, Risk

Assessment, Soil and Groundwater ManagementCapability to the Nuclear and civil sector.

Decommissioning the shaft is a unique project that requires innovation,collaboration and a very strong emphasis on safety and environmental

protection.

Warren Jones, DSRL

Fuel Cycle Area (FCA)

The Fuel Cycle Area (FCA) is the high security area within the

licensed site, housing the facilities that historically handled and

stored the sites nuclear material and waste.

Significant achievements in the decommissioning of the shaft and

Rosyth DockyardLocated near Edinburgh, nuclear activities on the site centred on the refuelling and refitting of nuclear powered submarines. In 1993,

the UK government announced that these activities would transfer to Devonport in southern England leaving a number of facilities at

Rosyth redundant and in need of decommissioning.

Site characterisation activities and monitoring works have been carried out prior to handing over for physical decommissioning works.

Various techniques have been used during the d decommissioning works phase including:

Plasma cutting of contaminated stainless steel tanks and plates

Designs and construction of mobile, re-useable temporary containment system for the decommissioning of the Low Active Effluent

Discharge line duct

Development of specific assay techniques to ensure minimisation of low level waste volumes
