2006 - Present
Representative projects
2006 AMEC Graduate Training Scheme (completed July 2008)
July 2006 – July 2008 Graphite Core Inspection Engineer.Working with the British Energy Graphite Core ProjectTeam at
AMEC. This team is responsible for the inspection (video and photo) of fuel and interstitial channels at several nuclear
power stations throughout the country. Work involved the analysis and classification of any cracks in the core. This also
involves reporting on and verifying remote in-core inspections. Organised inspections at EDF sites and liaised with
Barnwood for analysis of results. Wrote reports detailing inspections.
Assisting in Quarter-Scale Rig. Responsible for running several tilting experiments on a quarter-scale rig of an Advanced
Graphite Reactor (AGR) core.Involved tilting the quarter-scale model reactor through 30°,and measuring the displacement
of the fuel bricks within the rig.
2008 AMEC Engineer – Development and Test Services
July 2008 – January 2009 BCU Recovery Project. Involved in determining pre-stress for the Boiler Closure Unit(BCU) at
Heysham and Hartlepool power stations. Work included assessing Vibrating Wire Strain Gauge (VWSG) data from the
historical records.This analysis is usedto develop arguments thatpre-stress exists or does notexistin each specific BCU
at HYA and HRA.Involved in on-site inspections ofthe wire bundle on the BCUs.Trainedto use several pieces ofinspection
equipment to inspect wire bundle of BCU, and also to accurately interpret results.
January 2009 – January 2010 Full HeightFuel Channel Rig.Lead engineer responsiblefor a rig that replicates a full height
AGR fuel channel and fuel stringer.Responsible for construction,operation and analysis ofrig.Calibrated instrumentation,
constructed stringer and channel,and completed full testprogram on rig.Wrote several reports detailing the experimental
work and analysing the results. Designed and implemented small modification to the rig to then complete experimental

work with bowed stringers.Tests were carried outto provide data for in-situ gapping ofthe fuel stringer,extraction gapping,
tie bar load and fuel grab load traces, by extracting the replica fuel stringer from the distorted fuel channel.The initial test
work investigated the behaviour of a straightstringer in a distorted channel;the second test programme investigated the
behaviour of a bowed stringer in a distorted channel.
January 2010 – September 2010 HotBoxDome Project.Lead engineer for a dome heightdetection package and a pilecap
winch.Responsible for design implementation,manufacture and full trial programme ofboth units.Dome detectionpackage
involved a ferrous sensor lowered into a control rod channel to accurately determine the position of the hot box dome at
Heysham 1 power station.Winch was a bespoke design thatrotated 360° around centre of standp ipe while meeting EDF
strict rules on equipment in C2 contamination classification areas. Both delivered to a very demanding time scale.
Part of site delivery team for full deploymentof dome detection unit, drilling package and welding package.Worked within
a team of engineers to deliver project during outage at HYA R1 and R2.
September 2010 – October 2010 Magnox TSiF NAB / SAB Rig. Task engineer for TSiF North / South Acceptance Bay
(NAB / SAB) test rig.The rig was a mock up of a vessel atTrawsfynydd, and the purpose ofthe project was to remove and
transfer for disposal the remaining ILW sand, gravel and LLW inventory from each of the NAB and SAB sand pressure
filters followed by size reduction and removal of the 2 empty vessels. Developed method statements, risk assessments,
and full trial procedures as well as procuring equipment and ensuring rig build.
October 2010 – August 2011 Hot Box Dome Project Phase 2. Lead engineer for implementation oflessons learned from
phase 1 and production of new pile cap winches. Responsible for design implementation, manufacture and full trial
programme of both winches.
Part of site delivery team for full deploymentof dome detection unit, drilling package and welding package.Worked within
a team ofengineers to deliver projectduring outageatHRAR1 2011.A positive condition report(CR00690871) was raised
by Hartlepool station for the project.
August 2011 – February 2012 Career Break – Travelled around the world.
February 2012 – April 2012 Hot Box Dome ProjectPhase 3 Part of site delivery team for full deploymentof dome height
detection unit, drilling package,and welding package.Worked with a team of engineers to deliver projectduring outage at
HYA R2 2012.Involved in 24hr nightshiftpattern.4 control rod channels where drilled and the projectwas delivered safely
and to schedule.
May 2012 – January 2013 AMEC Thatcham – AWE MENSA Project. Seconded to work for AWE on the MENSA Project.
This project is comprised ofthe design and build of a new facility at AWE. The project includes the design,procurement,
installation, and commissioning through to handover of the completed building compliant to all modern codes and
standards. Worked as engineer assisting lead engineer. Developed knowledge of glovebox design and glovebox
integration within facilities at AWE. Developed knowledge of glovebox working procedures and arrangements.
Understanding ofAWE standards and processes learned,building several case files ofdocumentaryevidence to support
equipmentgoing throughAWE design review.Liaised directlywith the clientand sub-contractors to ensure allrequirements
being met and standards attained.Worked with subcontractors building remote TiGwelders,laser trimmers and electron
beam welders.
January 2013 – April 2013 Hot Box Dome Phase 4 Hartlepool R2 1 Channel ContinuationofHBD project at Hartlepool R1.
Central channel modified.
April 2013 – September 2013 URENCO TMF Noise Analysis Created and manipulated a noise model, using Brüel and
Kjær Predictor noise analysis software, of the proposed URENCO Tails Management Facility (TMF). Utilis ed plant and
building information to create a model thatpredicts sound pressure levels (SPLs) atvarious receiver positions.Noise data
was manipulated to obtain sound power levels for each octave band to allow entry in to the model.The effects of Louver s
and sound absorption was calculated, as well as the sound reduction properties of internal rooms, sound transmission
between rooms, and external sound transmission. Background noise measurements were taken with Brüel and Kjær
instrumentation to give an estimated increase in site noise level due to proposed building and plant.
June 2013 – October 2013 Hot Box Dome Phase 4 Heysham 1 R1 4 channels Continuation of HBD project at HYA R1.
Involved in 24hr night shift pattern. 4 control rod channels where drilled and the project was delivered safely and to
schedule.
