Chernobyl. At Chernobyl, the dangerous qualities of the reactor type came to a head, and the reactor Chernobyl-4 melted down in 1986. This catastrophe prompted the retrofitting of all existing RBMK reactors with several additional safety measures--many of these safety measures are directed at the reactor core in an effort to lower the void coefficient.

RBMK Reactors – Appendix to Nuclear Power Reactors (Updated July 2019) The RBMK is an unusual reactor design, one of two to emerge in the Soviet Union in the 1970s. The design had several shortcomings, and was the design involved in the 1986 Chernobyl disaster. Major modifications have been made to RBMK reactors still operating.

these reactors were practically copies of the first RBMK. They were constructed by using the technical project of the first RBMK reactor that was developed in 1960s [4]. This means that all RBMKs had similar shortcomings and an accident similar to the Chernobyl accident could happen at each Soviet NPP with a channel-type reactor [4].

Nuclear reactor - Nuclear reactor - Coolant system: The function of a power reactor installation is to extract as much heat of nuclear fission as possible and convert it to useful power, generally electricity. The coolant system plays a pivotal role in performing this function. A coolant fluid enters the core at low temperature and exits at a higher temperature after collecting the fission energy.
