"Change the fusion raw material?" Liang Qu looked over doubtfully, with some confusion in his eyes.

Xu Chuan nodded and said, "That's right, change the fusion raw material."

After a pause, he continued: "When we choose raw materials for controllable nuclear fusion, we usually choose hydrogen isotopes, because the electrostatic repulsion between lightweight nuclei is the smallest and fusion reactions are most likely to occur."

"So to achieve nuclear fusion, the first choice of materials is deuterium and tritium, which are isotopes of hydrogen. This is what the Daybreak fusion device uses."

"The advantage of deuterium-tritium fusion is that the reaction conditions are the loosest and the reaction temperature requirements are the lowest. However, the disadvantage is that neutrons cause material degradation, and high-energy neutrons take away most of the energy and cannot be used."

"Although the reuse of neutrons can be used to complete tritium self-sustainment, most of the energy taken away by high-energy neutrons is wasted."

"So actually, although it releases a lot of energy, we can use very little of it."

"Moreover, the deuterium-tritium fusion device also needs to use first wall materials and peripheral protective materials to cope with the impact of high-energy neutrons, which further increases the volume of the fusion reactor."

"So on the basis of deuterium and tritium fusion, I plan to change the raw materials for fusion."

Hearing this, Liang Qu nodded in agreement and said: "These are indeed the shortcomings of deuterium and tritium fusion, but if you change the fusion raw material..."

After a pause, he continued: "In the past, in addition to deuterium-tritium fusion, the mainstream areas of controllable nuclear fusion research also included deuterium-helium fusion, helium-3-helium fusion, deuterium-deuterium fusion, hydrogen-boron fusion, etc.

way."

"Compared to deuterium and tritium fusion, these fusion methods are more difficult. Each has its own advantages and disadvantages. Which one are you considering?"
