Q & A

What is nuclear fusion and why is it important?

Nuclear fusion is the process of combining light atomic nuclei, like hydrogen, to form heavier nuclei, releasing vast amounts of energy. It is important because it offers the potential for an almost limitless and clean energy source, using materials like seawater, which could greatly reduce dependence on fossil fuels and combat climate change.

What role does Italy play in the ITER fusion project?

Italy plays a crucial role in the ITER project by constructing key components such as the doughnut-shaped reactor, known as the 'Topamax', and the superconducting magnets that will hold the plasma at extremely high temperatures. Several Italian companies are involved in these critical tasks, showcasing the country’s leadership in advanced technology.

What are the main challenges in achieving nuclear fusion on Earth?

The main challenges include replicating the extreme conditions of the sun’s core, which requires temperatures of 100-200 million degrees Celsius and immense pressure. Additionally, no material can withstand such intense heat, so the plasma needs to be suspended in a vacuum and controlled using powerful magnetic fields.

How does the ITER project aim to achieve fusion energy?

The ITER project aims to achieve fusion energy by using a massive experimental reactor that will create the necessary conditions for nuclear fusion. The reactor will heat plasma to over 100 million degrees and contain it using powerful magnetic fields, allowing fusion reactions to take place and releasing energy for electricity generation.

What is the significance of the plasma in the ITER project?

Plasma is a hot, electrically charged gas made up of ions and free electrons, which is essential for fusion reactions. In the ITER project, plasma will be heated to extremely high temperatures (over 100 million degrees Celsius), and powerful magnetic fields will be used to contain it within the reactor, preventing it from touching the reactor’s walls.

What is the expected timeline for the ITER project?

The ITER project is expected to be completed around 2025, with the first fusion reactions anticipated to occur soon after. Following ITER, the next step will be the development of the DEMO reactor, expected around 2040-2050, which will demonstrate the ability to produce electricity from fusion on a commercial scale.

Why is the ITER project a significant example of international cooperation?

The ITER project involves multiple countries, including the European Union, the United States, Russia, China, Japan, South Korea, and India, working together towards a common goal. This collaboration is a powerful example of nations uniting to solve global energy challenges and promote peace, in contrast to rising nationalism and individualism.

How will the fusion energy produced in ITER be used?

The energy produced through fusion reactions in ITER will eventually be harnessed for electricity generation. This could provide a sustainable and clean energy source, helping to address global energy demands while reducing the environmental impact of traditional fossil fuels.

What are the economic benefits of Italy’s involvement in the ITER project?

Italy’s involvement in the ITER project is expected to generate significant economic benefits, including a return of around 2 billion euros and the creation of at least 1,500 permanent jobs. These investments are seen as crucial for the country's competitiveness and technological development.

How does the ITER project address the environmental challenges of energy production?

The ITER project addresses environmental challenges by aiming to produce clean, sustainable energy through nuclear fusion, a process that does not generate greenhouse gases or long-lived radioactive waste, unlike fossil fuels or traditional nuclear fission reactors. This could play a vital role in mitigating climate change.
