Why Nuclear Energy makes Sense for SA• South Africa is committed to reducing its GHG
emissions by 34% by 2020. (progress made?)
• Nuclear Energy is Clean Base-Load Power and
capable of making the greatest impact on CO₂ <
• Unpacking the nuclear spend: Capex + Owners
Costs + Cost of Capital (Spread over 15 Years
with early recoveries from generation income)
• Fuel Security – SA Uranium Reserves are No7 in
the world. On-site fuel storage long-term supply.
• SA’s Grid is capable of accommodating large scale
NPPs which is unique for Africa and cost effective.
• South Africa has an established Nuclear Energy
industry with world-class education facilities.
• Our base-load supply capacity is currently under
pressure, with some medium term relief but retiring
~20GW of base-load capacity from 2025 to 2035.
Nuclear Energy could be a perfect replacement.
A Construction Perspective on a
Nuclear Build Program in South Africa
• Nuclear Power Plants are 50% conventional
construction and 50% nuclear construction.
• World class construction standards are
being developed on Medupi and Kusile.
• Nuclear Construction requires a new level of
quality, codes and specifications to
guarantee “Nuclear Safety”.
• The development of these nuclear quality
standards has been achieved by a top
South African construction company.
• Preparation of SA industries for nuclear
grade manufacturing and construction will
take 3 to 4 years for localisation.
• The industry nuclear readiness program will
be influenced by the nuclear vendor country.
• Lessons Learned from international nuclear
build programs will benefit South Africa

Localisation to date at
Koeberg Nuclear Power
Stationsince the early 1980’s
Localised Nuclear Projects
Eskom:– Structured organization
– Services and projects outsourced to contractors
– Contractors able to cross skill for other industries (local and abroad)
Contracts for various scopes of work (flexible):– Various projects / modifications/ services outsourced to contractors at Koeberg
Nuclear Power Station
General Outage Activities at Koeberg (various contractors):– General maintenance activities
– Electrical and wiring Services
– Rigging and Welding activities
– HVAC maintenance
– Supply of Radiation Protection personnel
Nuclear Projects and Successful Execution – Strong organisaltional Nuclear Culture across the supply chain (RD-0034)
– Competence and experience is fundamental
– Processes, documentation, certification, authorisation and implementation
– Do it right first time, cost of quality is significant!
Current: PTR Tank Replacement
• Lesedi and Group Five (consortium) were awarded a contract with Eskom for the replacement of two large stainless steel tanks at Koeberg.
• The total scope of the project is divided into 5 packages, of which Lesedi and Group Five obtained package 1 (tank replacement) and package 4 (decontamination and waste disposal). This constitutes ±80% of the total project value.
• Lesedi is the lead consortium partner. AREVA, Lesedi’s main shareholder and OEM at Koeberg are subcontractors to the consortium, mainly for the tank design scope.
Current: Steam Generator Replacement
• Replacement of 6 Steam Generators – Lesedi lead in local consortium to AREVA
– Scope• Engineering and design with regard to the consortium
responsibilities
• All site related works for the removal and replacement of the steam generators
– SG supports & primary pipe supports removal and replacement
– Clamping (temp support) installation & removal for primary pipes
– Concrete Core Drilling of all holes required & closing holes afterwards
– Site Electrical (temporary supply & electrical interferences) requirements
– New SG preparation – Provide Artisans / semi-skilled
– Site Establishment (Provision of offices, furniture, etc.)
– Supply RP labour to AREVA – hanging of lead blankets
– Commissioning assistance to AREVA.
– Supply and operation of jib crane in reactor building
– Rigging activities
• Job creation and skills transfer during the project– 57 new jobs to be created: project managers, engineers,
technicians, riggers artisans, radiations monitors, QC and construction managers
– On the job training for 22 individuals: QA/QC, planning, commissioning, project controls, construction, project management
The above commitments are supplementary and above the project team and other training by the local consortium and AREVA

Lessons Learnt: Major Build Programmes
“the only lesson learnt is the lesson not to learn” A. Einstein.
• Medupi; over budget, late, labour (MLI)
– Lesedi and its partners will achieve over 85% local content on BOP (contract value >R2billion)
– Kusile, Ingula, Gautrain
• REEIPP: localisation really a success?
• Nuclear new build around the world
– Macro environment differences (e.g. China)
• Prescriptiveness on localisation, how far to go ?
– Local to site, BBEEE, PPPFA ? Transaction cost vs diversification, Nuclear Regulations, economics 101
• Vendor experience and value proposition for South Africa – Localisation strategy will impact on Overall Price
– What to localise, how to localise and risk• Many audits conducted locally, some vendors since 2007 in South
Africa
• Skills transfer is it real ?
Localisation Conundrum
• Financing vs country risk – Localisation realities will be impacted by upfront planning and
financing of the nuclear programme vs risk vendors are willing to take
– Building Own Operate Transfer (BOOT) model ?
• What to localise?– Upskilling of resources a must – semi skilled, unskilled
• Every country has localisations ambitions– Manufacture where our strength lies and future growth resides
(export markets and diversification)• Quantities, investment, competiveness
– Upskilling: artisans, engineers, planners, supervisors, technicians, construction, QA/QC, commissioning
– Key equipment: Valves, Pumps, Piping, HVAC, FIRE, Tanks, Cranes, Steel. Etc.
– Various studies commissioned in recent years by academic institutions, associations (NIASA), consultants and vendors
