What are projects about nuclear controlled fusion reactor to achieve Q > 1

In summary, the conversation discusses projects related to nuclear controlled fusion reactors and the goal of achieving a Q > 1 or even Q = 10 for efficient power plant design. The main focus is on the ITER project, which involves a hydrogen plasma torus operating at extremely high temperatures and producing 500 MW of fusion power. Other relevant sites and experiments are also mentioned, including the Fusion Ignition Research Experiment (FIRE) and the performance of JT-60.

What are projects about nuclear controlled fusion reactor to achieve Q > 1, or possibly obtain Q > 1.

You have asked this in another thread, why are you making another thread?

I think a thermonuclear bomb would qualify as having Q greater than one, but that is not controlled as well as anyone would like.

The goal of ITER is to achieve a Q = 10, to have a high enough thermal efficiency for a power plant design.

I was wondering about that but I could not find the specific information until now.

It is based around a hydrogen plasma torus operating at over 100 million °C, and will produce 500 MW of fusion power.

Here's a few links about the performance of JT-60 if you're interested. I guess they were able to reach gains of 1.25 or thereabouts.

What is a nuclear controlled fusion reactor?

A nuclear controlled fusion reactor is a type of power plant that uses nuclear fusion, the process of combining two atomic nuclei to form a heavier nucleus, to produce energy. It is similar to the process that powers the sun and other stars. In a controlled fusion reaction, the energy released is harnessed to create electricity, with minimal impact on the environment.

What does Q > 1 mean in relation to a nuclear controlled fusion reactor?

Q > 1 refers to the ratio of energy output to energy input in a fusion reaction. In order for a controlled fusion reaction to be considered successful, Q must be greater than 1, meaning that the amount of energy produced is greater than the amount of energy required to sustain the reaction. This is a key milestone in the development of a viable fusion energy source.

What are the potential benefits of achieving Q > 1 in a nuclear controlled fusion reactor?

If Q > 1 can be achieved in a controlled fusion reaction, it would mark a major breakthrough in the development of fusion energy technology. This would mean that fusion reactions could produce more energy than they consume, making fusion a potentially limitless and sustainable source of clean energy. It could also help reduce our dependence on fossil fuels and decrease our carbon emissions, mitigating the impacts of climate change.

What are the challenges in achieving Q > 1 in a nuclear controlled fusion reactor?

One of the main challenges in achieving Q > 1 in a controlled fusion reaction is the extremely high temperatures and pressures that are required to initiate and sustain the reaction. These conditions are difficult to achieve and maintain, and also cause wear and tear on the materials used in the reactor. Additionally, finding a way to efficiently harness and convert the energy released by the fusion reaction into usable electricity is another major challenge.

How close are we to achieving Q > 1 in a nuclear controlled fusion reactor?

While progress has been made in fusion research, we are not yet at the point of achieving Q > 1 in a nuclear controlled fusion reactor. Many experimental reactors have been able to produce fusion reactions, but have not yet been able to sustain them long enough or produce enough energy to achieve Q > 1. However, with ongoing research and advancements in technology, scientists are optimistic that we will be able to achieve this milestone in the near future.
