Country Profile: Ukraine (Observer)


Ukraine is an eastern European country bordered by Poland, Russia, Belarus, Slovakia, Hungary, Romania, and Moldova. It gained independence from the Soviet Union following the latter’s dissolution in 1991. Today it is a unitary, semi-presidential constitutional republic.

Capital: Kiev

Ukraine has three nuclear research reactors currently in operation. SNI, IR-100 is a pool-type, light water reactor operated by the Sevastopol University of Nuclear Energy and Industry used for isotope production, education & training, activation analysis, and transmutation; the University also operates SPh IR-100, a critical assembly used for training. WWR-M Kiev is a WWR tank reactor operated by the Ukraine Institute for Nuclear Research and is used primarily for isotope production, materials testing, and activation analysis. Additionally, a subcritical assembly and a general-purpose research reactor are currently in the planning or early construction stages.

Over half of the electricity in Ukraine’s national power grid comes from nuclear power plants. Fifteen reactor units are currently operational, each of which a PWR-type VVER-V320 and operated by the state-owned national energy enterprise ENERGOATOM. Two additional units (KHMELNITSKI-3 and KHMELNITSKI-4) are currently under construction, to be PWR-type VVERs.

In 1986 Ukraine experienced one of the largest nuclear accidents in history when one of the four RBMK, LWGR-type reactor units at the Chernobyl Nuclear Power Plant exploded during a safety test. All four units have been in permanent shutdown since 2000.
