In nuclear reactors, refueling—the planned removal of spent fuel assemblies from the reactor core and their replacement with fresh fuel, alongside the strategic rearrangement of remaining fuel assemblies—is a critical core management process that directly affects reactor reactivity control, power distribution, safety margins, and economic operation. In Pressurized Water Reactors (PWRs), periodic fuel replacement operations are essential for continuous and safe energy production. The fundamental

Reactor simulation is the process of examining, predicting, and optimizing the behavior of highly complex systems such as nuclear, chemical, or biological reactors using mathematical models and numerical methods in a computer environment. This approach is based on recreating the fundamental physical and chemical processes occurring within the reactor in a virtual setting. These processes include nuclear fission and fusion reactions, heat transfer mechanisms, fluid dynamics, mass transfer, phase

Protactinium is a rare and radioactive element in the periodic table. It occurs in very small amounts in nature, and scientists study it in laboratories for research purposes.Discovery and NameProtactinium was discovered in 1913. Its name derives from Greek words meaning "pre-actinium," as it exhibits properties very similar to the element actinium.PropertiesProtactinium is a metallic and radioactive element. It has a silvery appearance but is extremely rare in nature. Its chemical properties ar

Uranium enrichment is the artificial process of increasing the proportion of uranium-235 (U-235), the isotope found in natural uranium that enables energy production in nuclear reactors. This process is carried out to produce fuel for nuclear reactors or to obtain material for nuclear weapons. Natural uranium consists primarily of two different types (isotopes) of uranium:Uranium-238 (U-238): Makes up approximately 99.3 percent of natural uranium. This isotope cannot be used directly for energy

Gadolinium is a silvery-white metal with atomic number 64, belonging to the lanthanide series. It was discovered in 1880 by the Swiss chemist Jean Charles Galissard de Marignac and named after the Finnish chemist Johan Gadolin. It is particularly used for its magnetic properties in nuclear reactors and medical imaging applications.Classification and Basic PropertiesGadolinium (Gd) is an element located in the 6th period of the periodic table within the lanthanide group. Its electron configuratio
