Switzerland’s nuclear power plants, initially designed to last 40 years, are expected to remain operational for at least 60 years due to the slow progress in renewable energy expansion. The Leibstadt nuclear power plant, the largest in Switzerland, plays a crucial role in this extended lifespan. Despite its monolithic appearance, the power plant is a hub of continuous planning and construction.
When the Leibstadt nuclear power plant was commissioned in 1984, it was expected to operate for only 40 years. However, as the Swiss energy landscape has changed, there is now a need for these facilities to operate for longer periods. This is primarily because of the stagnation in renewable energy expansion and the increasing demand for electricity during winter months when nuclear power plants can contribute up to 50% of the required electricity.
To ensure that the Leibstadt nuclear power plant remains safe and functional for extended periods, meticulous planning and continuous upgrades are necessary. The plant undergoes regular inspections and refurbishments, with over 200 ongoing projects aimed at improving monitoring, digitalization, and other aspects crucial for long-term operation. These projects are expected to cost around 1 billion francs over the next decade.
Safety measures at the nuclear power plant are paramount and include ultrasound tests on reactor pressure vessels and regular monitoring. Any project that poses a threat to safety standards would not be approved by supervisory authorities. The plant also follows regulatory requirements by retrofitting itself to remain at the forefront of nuclear technology developments for safety enhancement purposes.
The planned operational duration management tool at the Leibstadt nuclear power plant aims to optimize projects so that they achieve a lifespan of at least 60 years while maintaining economic viability. Uncertainties in electricity prices make long-term planning challenging; therefore, key projects must be planned ten years in advance.
Despite facing complex challenges and requirements, the Leibstadt nuclear power plant remains committed to meeting safety standards while continuing its operations for an extended period.
With careful planning, ongoing upgrades, and adherence to regulatory requirements, nuclear power plants like Leibstadt can continue playing a central role in Switzerland’s energy supply for years to come.
