Context and challenges


The success of the energy transition underway will rely on our ability to meet the world’s increasing demand for energy while also drastically reducing CO2 emissions.

To support this growth, Assystem Stup believes nuclear power must be one of the cornerstones of the energy transition, as the only massive source of low-carbon power that can reliably replace fossil fuels while meeting baseload electricity demands.

The nuclear industry must therefore continue to improve its competitiveness while strengthening its safety requirements by:

Developing new nuclear capabilities while optimising the schedule and budget

In 2015, the International Energy Agency’s Technology roadmap concluded that “global capacity must more than double, with nuclear providing 17 percent of global electricity generation in 2050, to meet the IEA’s 2-degree scenario for the most effective and efficient ways to limit global temperature.” A crucial challenge for the nuclear industry is controlling delivery times and costs for new nuclear programs.

Improving operating performance

Nuclear operators can reduce operating costs and efficiency by taking advantage of the latest digital technologies. Digitalised control systems combined with plant-wide sensors, provide operators with a better understanding of the plant’s status, allowing the optimisation of operating parameters and supporting intelligent planning of maintenance activities.

Constantly improving safety and security

The safety of nuclear facilities is a constant concern for the entire sector, and dictates a large part of the choices made from design to operation and decommissioning. Strongly regulated and controlled by an independent authority, security and safety standards are constantly being raised, pushing the entire sector towards excellence. This is reflected in the development and refinement of ever-safer systems and the ongoing training of operators based on internationally-exchanged best practices.

Extend lifetime of existing generation facilities

Many facilities originally designed for a 30-year life are now being extended to operate for 40, 50 or even 60 years. Life extensions must be justified on both safety and financial viability grounds. Replacement of components and systems can be undertaken to maintain adequate safety margins, but this requires significant investment and planning by plant owners.

Digitalised control systems, combined with plant-wide sensors, provide the operator with a better understanding of the plant’s status, allowing the optimisation of operating parameters and facilitating intelligent planning of maintenance activities.
