VVER-440 fuel assemblies (FA) have been manufactured since 1963. Presently supplies are made to meet the demands of NPP in Russia, Ukraine, Armenia, Eastern European countries and Finland.
A VVER-440 FA is composed of 126 fuel rods with zirconium alloy claddings, which are filled with fuel pellets of uranium dioxide.
To improve reactor physical properties and safety some fuel rods are filled with pellets containing gadolinium oxide.
