nine new clean and green energies 2

Clean energy refers to environmentally friendly energy sources, indicating eco-friendliness, minimal emissions, and low pollution levels. However, this concept is not precise enough and can easily lead people to misunderstand it as a classification of energy sources, believing that there is a division between clean and dirty energy sources, thereby misconstruing the true meaning of […]

Other components of the nuclear reactor system

1. Moderator The moderators currently widely used in thermal neutron reactors are ordinary water, heavy water and graphite. Graphite is a black and soft anisotropic carbon body, which is stable in a wide temperature range. It has good mechanical properties, thermal stability, and low price; its nuclear performance is slightly inferior to heavy water, and […]

Nuclear fuel and coolant for nuclear reactor systems

1. Nuclear fuel Nuclear fuel refers to materials containing fissile nuclides (uranium-235, plutonium-239, uranium-233). It can realize self-sustained nuclear fission chain reaction under certain conditions. Currently, the most widely used nuclear fuel is uranium. It is divided into natural uranium (0.72% uranium-235 content), low-enriched uranium (0.7%-20% uranium-235 content) and highly enriched uranium (uranium-235 content 20%-90%) according […]
