NCI has significant experience in the project management of multi-disciplined turnkey projects

Since its inception NCI has been providing service excellence, both nationally and internationally and is committed to the delivery of service excellence on time, to cost and to the highest levels of quality.

NCI serves both the public and private sector and focuses on undertaking projects that incorporate specialist technologies or require the highest levels of enhanced project management services.

NCI has considerable experience in the performance of feasibility studies and the development of conceptual designs for a wide range of industrial and commercial projects.

The team is skilled in the identification and evaluation of alternative solutions to complex engineering problems, the analysis of existing risks, expenditure and opportunity costs, the project costing as well as the cost benefit analysis of the identified solutions.

The Design Engineering Team provides a skilled engineering resource committed to the resolution of complex engineering problems and the delivery of service excellence to customers.

NCI Design Engineers have proven expertise in the design, development and integration of engineering solutions for new technologies requiring advanced, innovative or safety related approaches and have extensive experience in the nuclear and the wider engineering fields. This includes an extensive knowledge of applicable design codes and standards associated with nuclear and conventional plant design.

The key areas of expertise include Electrical, C&I, Mechanical, HVAC, Civil and Structural Design.

NCI engineers have historically been and are currently involved in the detailed design of a number of multi- disciplinary safety related modifications at Koeberg Nuclear Power Station. We have also sucessfully installed & commissioned backup diesel generating plants involving complex logic design for plant integration with the main Power Generating Plant at both Medupi and Kusile Power Stations situated in respectively the Limpopo and Mpumalanga Provinces of South Africa.

NCI has developed considerable skills and experience in the successful project management and completion of turnkey projects from conceptual design through detailed design, installation, testing and commissioning to handover. We further provide a one-year defects period on installation and equipment after the plant handover.

Our multi-disciplined teams (including specialist subcontractors) directed by our highly experience project managers have been responsible for the successful realisation of several of modifications on various sites.

NCI’s specialist maintenance team has vast experience in maintenance engineering and performing analysis to define the optimal Preventative Maintenance requirements for specified plant systems and equipment at which could potentially affect plant availability and safety.

This work includes:

• Identification and prioritisation of maintenance significant systems and equipment that affect plant availability
• Analysis to determine an applicable and effective maintenance programme
• Implementation of the revised maintenance programme including procedures and service notifications.

NCI has developed considerable skills and experience in the procurement and specification of conventional and nuclear qualified equipment, spare parts and components.

This experience also extends to the qualification of equivalent components and the reverse engineering of components no longer available in the market, resulting in considerable cost savings to the customer.

The team also has extensive experience in the production of functional, technical and procurement specifications and conventional and nuclear plan as well as the classification of equipment and components.

NCI has a strong team skilled in risk and safety analysis. The team provides a core of dedicated PSA/Reliability experts with extensive experience covering the full range of PSA and reliability techniques.

Work undertaken has ranged from small scale assessments and risk analysis for plant modifications to complete Probabilistic Safety Analysis (PSA) for nuclear plants. NCI staff have been involved in several PSA’s throughout Europe and were influential in the development of the Koeberg PSA. NCI was also heavily involved in the development of the PSA for the new Pebble Bed Modular Reactor (PBMR) currently under development in South Africa.

The areas of expertise cover all elements of Level 1 and Level 2 PSA including:

• Failure Modes and Effects Analysis;
• Event Tree Analysis;
• Fault Tree Analysis;
• Human Reliability Assessments;
• Hazard Analysis;
• Radiological Analysis.

NCI has also developed considerable skill in the use of the RiskSpectrum Analysis Tool.

NCI also has extensive experience in severe accident analysis. The analysis techniques have been applied to develop strategies for, and to design and implement modifications for:

• Hydrogen control in containment
• Filtered containment venting
• Reactor pit flooding

NCI also has considerable expertise in the development and application of Severe Accident Management Guidelines (SAMG) for Nuclear Reactors.

The safety case and licensing team is made up of a broad range of nuclear engineers, physicists and other specialist consultants.

All members of the team have extensive experience in the nuclear power generation other major hazardous industries throughout South Africa, the UK and Europe.

The primary role is the production and modification of safety cases for clients in any plant area for all major types of reactor.

It can also provide valuable licensing support on specific licensing issues related to plant modifications as well as the construction of new novel reactor types.

The team has the capability to provide the required analysis to justify and provide substantiation to a vast range of nuclear an conventional safety cases.

NCI can undertake a vast range of specialised tasks and projects not specifically detailed.

This is because NCI engineers have a considerable range of experience and access to an extensive pool of highly qualified and experience nuclear engineers and other technical resources form our vast network of consultants and parent organisations for larger and more specialised tasks and projects.

Our approach is to work closely with our customers engineering staff to correctly understand their requirements or problems. In this manner, the most cost-effective engineering solutions are achieved, together with buy-in from the customer.

Some of the areas where NCI can offer specialist consultancy services includes but is not limited to:

• Pipe Stress Analysis (Caesar Code)
• Fluid and Flow Analysis
• Structural and Seismic Analysis
• Reactor Physics
• Criticality Assessments
• Fracture Mechanics
• Radiological Assessments and Shielding
• Technical documentation and Procedures
• Operations Support
• Deterministic Safety Analysis
• Chemistry and Chemical Analysis
• Materials Engineering
• Atmospheric Stress Corrosion Cracking
• Environmental Impact Assessments
• Probabilistic Safety Analysis (PSA)
