Featured Media: Working Beyond the Design Life of a Nuclear Energy Plant

One of the keys to a successful life extension program for nuclear power plants is the modelling and simulation processes required to support nuclear risk assessments. Methods can include Finite Element Analysis and Seismic Walkdown, but both these methodologies are critical.

According to the International Atomic Energy Agency (IAEA), more than two-thirds of the world’s 442 nuclear power reactors are now over 30 years old and approaching or already surpassing the end of their originally anticipated 40-year lifespan.

Around 100 of those reactors globally have already had their operating licences extended. However, the IAEA also projects that, unless more operating licences are extended, existing nuclear capacity will decline sharply before 2030, particularly in Europe and North America, with all existing plants scheduled to retire by 2060.

Set against the background of an electricity generation sector that faces the immense challenge of shifting almost entirely from fossil fuels to low carbon energy sources by 2050, extending the lifespan of nuclear power generation plants could provide an effective route to help meet the future low emissions energy goals.

Our expert Andrew Buckley shares his insight and explains why the Safety Case for extending the lifespan of a nuclear facility involves multiple complex processes involving every operational aspect of a plant. For those looking to extend the lifetime expectancy of a plant, having a clear, thought through plan utilising FEA and Seismic Walkdown methodologies, can be greatly beneficial.
