Answer: set
Explanation: because why would set be a verb.
Answer:
The Chernobyl disaster was a nuclear disaster that happened on April 26, 1986, at the Chernobyl Nuclear Power Plant's No. 4 reactor in Private in the Ukrainian Soviet Socialist Republic. In terms of both cost and casualties, it is the greatest nuclear disaster ever. It was caused by Reactor design flaws and serious breach of protocol during simulated power outage safety test. It ended in a Level 7 (major accident). The Chernobyl disaster in 1986 was caused by a faulty reactor design that was operated by people who were not properly qualified. The steam explosion and flames that followed discharged at least 5% of the nuclear reactor core into the environment, resulting in radioactive elements being deposited in numerous parts of Europe. The Chernobyl Power Complex, located about 130 kilometers north of Kiev, Ukraine, and about 20 kilometers south of the Belarusian border, consisted of four RBMK-1000 nuclear reactors (see information page on RBMK Reactors). The first two units were built between 1970 and 1977, while the third and fourth units of the same design were finished in 1983. At the time of the catastrophe, two more RBMK reactors were being built at the site. To the southeast of the plant, a 22-square-kilometer artificial lake was built alongside the river Pripyat, a tributary of the Dniepr, to provide cooling water for the reactors.The Chernobyl Power Complex, located 130 kilometers north of Kiev, Ukraine, and 20 kilometers south of the Belarusian border, was made up of four RBMK-1000 nuclear reactors (see information page on RBMK Reactors). Units 1 and 2 were built between 1970 and 1977, with units 3 and 4 following in 1983. At the time of the accident, the site had two more RBMK reactors under construction. An artificial lake of 22 square kilometers was built to the southeast of the plant, next to the river Pripyat, a tributary of the Dniepr, to provide cooling water for the reactors. The disaster resulted in the largest uncontrolled radioactive leak into the environment ever recorded for a civilian activity, with enormous amounts of radioactive compounds spilled into the air for roughly ten days. For vast populations in Belarus, Russia, and Ukraine, this wreaked havoc on their social and economic lives. The short-lived iodine-131 and the long-lived caesium-137 radionuclides were particularly important for the radiation dose they gave to the general populace.
