Support to the Nuclear Industry

The global need for decarbonisation requires a radical shift in electricity generation mix. The 'business as usual' option is not sustainable on the grounds of energy security, affordability and environmental impacts. Nuclear power is currently the only option that can globally deliver low-carbon base load electricity at competitive prices. Projections range a nuclear share of between 24% and 38% of global electricity production by 2050. Currently around 65 countries are implementing or planning new nuclear power programmes.

Current nuclear nations are also seeking to extend the lives of their existing nuclear generation plants. Operators of plants that have an original design life of 30-40 years are undertaking extensive structural integrity assessments and refurbishment in order to ensure the long-term safety of the plants.

For nations with a history of nuclear operations, waste management and decommissioning are now high-profile activities with a requirement for the safe and efficient methods of packaging, storing and eventual disposal of the various waste streams.

TWI has over 70 Member companies that operate in the global nuclear industry. Such companies cover the complete spectrum of activities from power utilities, fuel cycle companies, research and development organisations, regulators and a large range of engineering contractors from both the civil and defence sectors. To date, over 800 separate nuclear projects have been completed over a period of some 35 years. Activities have included:

Industry challenges

  • Very large initial investment and financing requirements
  • Construction risks
  • Public acceptance, safety and waste management
  • Security and proliferation issues
  • Constraint on human resources and equipment supply
  • For emerging nuclear countries: a need for capacity building and institutional/regulatory frameworks
