It is assumed that there is no high level waste produced in fusion but on calculating some isotopes are very long lived and very highly radioactive. And also they says that in maintenance worker are allowed to access after 12 days of shutdown but is this acceptable i think the activity level will be very high.Simon Bridge said:Activation is needed for a fusion reaction for the same reason you need activation to light a fire ... but the specific meaning can depend on the context. For instance, in the headline "Germany activates first fusion reactor" it just means they switched it on.

I am also working on this and i have some data what kind of data you need i will send you, no problemDrakkith said:A substance is either very long lived or highly radioactive, not both. A highly radioactive substance decays at a much quicker rate than a less radioactive substance (and the more decays per second the more radioactive it is), so it has a shorter lifetime.
Do you have a source for all of this? I'd be interested in reading it.
Fusion activation is a process that involves initiating and controlling a nuclear fusion reaction, where two atomic nuclei combine to form a heavier nucleus. This process releases a large amount of energy, which can be harnessed for various applications.
Analysis and calculation in fusion activation involve using mathematical and computational methods to predict and understand the behavior of the fusion reaction. This includes studying factors such as temperature, pressure, and fuel composition to determine the most effective conditions for fusion to occur.
Fusion activation is needed because it has the potential to provide a nearly limitless source of clean energy. Unlike traditional nuclear fission reactions, fusion reactions produce minimal radioactive waste and do not contribute to climate change. Additionally, fusion fuel, such as hydrogen, is abundant and can be extracted from sources such as seawater.
One of the main challenges in achieving fusion activation is creating and maintaining the extreme conditions necessary for fusion to occur, such as high temperatures and pressures. Another challenge is containing the high-energy plasma produced by the fusion reaction, as it can damage or melt any known material.
Fusion activation research has made significant progress in recent years, with multiple experiments successfully producing fusion reactions and releasing net energy. However, there are still many technological and scientific challenges that need to be overcome before fusion can be harnessed as a viable energy source. Ongoing research is focused on developing new materials and technologies to improve the efficiency and stability of fusion reactions.
