ydinlähteet

Ydinlähteet refers to the primary sources of energy used in nuclear power generation. These sources are characterized by their ability to undergo nuclear fission, a process where the nucleus of an atom splits, releasing a significant amount of energy. The most common ydinlähteet utilized in nuclear reactors are isotopes of uranium, particularly uranium-235 (U-235). Thorium, especially thorium-232 (Th-232), is also considered a potential ydinlähde for future nuclear reactor designs.

The energy released from nuclear fission is harnessed to heat water, which then produces steam. This steam drives turbines connected to generators, producing electricity. The selection of a specific ydinlähde depends on factors such as its availability, cost, enrichment requirements, and compatibility with different reactor designs. Uranium-235 is widely used due to its fissile properties and established fuel cycle infrastructure. Thorium, on the other hand, is more abundant and has the potential to breed its own fissile material (U-233) in a thorium fuel cycle, offering advantages in terms of waste reduction and resource sustainability. Research and development continue to explore and optimize the use of various ydinlähteet for safe and efficient nuclear energy production.
