- Co to jest PWR Technologia?

A Pressurized Water Reaktor (PWR) is a type of light- water nuclear reactor in which te primary colocant water is maintained at high pressure - typically around 150 atmospheres - to prevent it from boiling while cyrkulating the reactor core andads absorbing heat from nuclear fission. This heate water then flow to a steam generator, where itt transfers its thermal energy ta a seconsecondary water loop, producting m stead m thatheatter.

Key Components and How They Work

Te reaktor core contains fuel assemblies made of enriched uranium dioxide pellets stacked inside zirconium alloy cladding tubes. Contral rods, made of neutron-absorbing materials such as boron or hafnium, are inserved or contact to regulate the fission rate.

When consideragg the full lifecycle - including g mining, fuel facation, construction, and dempmissioning - thee carbon footprint of nuclear power is comparable to wind andd hydropower and far lower than any fossil fuel source.
