Editing Chernobyl Nuclear Power Plant (section)

=== 1982 reactor #1 partial meltdown ===
On 9 September 1982, a partial [[nuclear meltdown|core meltdown]] occurred in reactor No. 1 due to a faulty cooling valve remaining closed following maintenance. Once the reactor came online, the uranium in the channel 13-44 overheated and ruptured. The extent of the damage was comparatively minor, and no one was killed during the accident. However, due to the negligence of the operators, the accident was not noticed until several hours later, resulting in significant release of radiation in the form of fragments of uranium oxide and several other radioactive isotopes escaping with steam from the reactor via the ventilation stack. This accident was somewhat similar to the 1975 Leningrad unit 1 accident. The accident was not made public until several years later, despite cleanups taking place in and around the power station and Pripyat. The reactor was repaired and put back into operation after eight months.<ref>{{Cite book|url=https://books.google.com/books?id=WwPJDwAAQBAJ&q=rbmk+serpentinite&pg=PA61|title=Midnight in Chernobyl: The Untold Story of the World's Greatest Nuclear Disaster|first=Adam|last=Higginbotham|date=February 4, 2020|publisher=Simon and Schuster|isbn=9781501134630|via=Google Books|access-date=May 3, 2021|archive-date=September 1, 2021|archive-url=https://web.archive.org/web/20210901025133/https://books.google.com/books?id=WwPJDwAAQBAJ&q=rbmk+serpentinite&pg=PA61|url-status=live}}</ref>
