Nuclear power in Ukraine balance account. Three of them Vatutine, Central, and Michurinske were being developed, while at the Novokostiantyniv was being built an ore enrichment factory. Number of deposits are exhausted (i.e. Devladove, Zhovtorichenske, Pershotravneve, Bratske). All of Ukraine's RBMK reactors (the type involved in the 1986 Chernobyl nuclear disaster) were located at the Chernobyl Nuclear Power Plant. All of the reactors there have been shut down, leaving only the much safer VVER reactors operating in the country. Three of the reactors listed were built in post-independence Ukraine, with the first one of these being constructed in 1995; the other sixteen reactors the
Chernobyl Nuclear Power Plant was equipped with both types of turbines; Block 4 had the newer ones. The newer turbines, however, turned out to be more sensitive to their operating parameters, and their bearings had frequent problems with vibrations. Four RBMK reactors were at Chernobyl Nuclear Power Plant, Ns. 1–4. The construction of two partially completed reactors, numbers 5 and 6, was suspended immediately after the accident at reactor N. 4, and was eventually cancelled in 1989. Reactors 1-3 continued to operate after the disaster. Reactor N. 2 was permanently shut down in 1991 after a fire broke out due to a faulty switch
