Alternative generating capacity was needed, either gas-fired, which has ongoing fuel cost and supply implications, or nuclear, by completing Khmelnitski unit 2 and Rovno unit 4 ('K2R4') in Ukraine. The cost of the work was put at BYR 6.6 trillion ($2.2 billion), split fairly evenly across the years 2011 to 2015 inclusive.The RBMK-1000 is a Soviet-designed and built graphite moderated pressure tube type reactor, using slightly enriched (2% U-235) uranium dioxide fuel. This task represents the most important step in eliminating nuclear hazard at the site – and the real start of dismantling.
However, the structure is neither strong nor durable. (based on the proceedings of the IAEA/WHO/EC International Conference, Vienna, April 1996), International Atomic Energy AgencyThe 1991 report by the State Committee on the Supervision of Safety in Industry and Nuclear Power on the root cause of the accident looked past the operator actions.
Last year that figure was even higher, after the success of an HBO mini-series about the disaster. The second half was completed by the end of 2014 and was joined to the first in July 2015. The entire 36,000 tonne structure was pushed 327 metres into position over the reactor building in November 2016, over two weeks, and the end walls completed. The NSC is the largest moveable land-based structure ever built.The Chernobyl Shelter Fund, set up in 1997, had received €864 million from international donors by early 2011 towards this project and previous work. The International Atomic Energy Agency (IAEA) safety review projects for each particular type of Soviet reactor are noteworthy, bringing together operators and Western engineers to focus on safety improvements. Apart from the initial 116,000, relocations of people were very traumatic and did little to reduce radiation exposure, which was low anyway.
Thirdly, €15 million for social projects. Construction was completed in January 2020. The overpressure caused the 1000 t cover plate of the reactor to become partially detached, rupturing the fuel channels and jamming all the control rods, which by that time were only halfway down.
