New Launch Date for ITER Nuclear Fusion Reactor: The Challenges and Promises of an Ambitious Energy Source

The ITER nuclear fusion reactor in France’s Saint-Paul-lez Durance is facing delays in its initial experimental phase, with a new launch date of 2034 announced by the project team. Originally, the reactor was supposed to be launched for testing at low energy levels in 2025. However, due to the pandemic and issues with certain parts, the launch date has been pushed back.

The reactor’s ultimate objective is to produce energy through the fusion of hydrogen atoms, simulating the processes that occur on the Sun. To achieve this, the hydrogen plasma must be heated to 150 million degrees Celsius, with the reactor eventually producing ten times more energy than it consumes. In order to effectively mitigate risks and achieve these goals, engineers have altered plans and decided to explore plasma from the beginning rather than starting with a ‘bare’ machine as originally planned.

The collaborative project involves several countries including the European Union, United States, Russia, China, India, Japan and South Korea. Initiated in 2010, ITER’s estimated cost exceeds 20 billion euros. Supporters of ITER believe that nuclear fusion could provide a climate-friendly and virtually unlimited energy source while critics argue that ITER is overshadowing renewable energy sources.

Experts involved in ITER stress that delays should not come as a surprise given the impact of COVID-19 and issues with part quality. Many critical components would not have been available by 2025 had it been released as planned. The change in plans will entail additional costs amounting to several billion euros.

ITER’s goal is ambitious but also challenging; it requires overcoming numerous technical hurdles and risks associated with working with extreme temperatures and radiation levels. Nevertheless, experts believe that nuclear fusion has enormous potential as an energy source for powering future generations if we can harness its power safely and efficiently.
