The Chernobyl disaster significantly impacted the Soviet power grid, leading to the eventual shutdown of the reactors over the years. While Reactor No. 4 failed in April 1986, the other reactors continued operating for several years, with No. 1 shutting down in November 1996, No. 2 in October 1991, and No. 3 in December 2000. The Duga radar system, which likely relied on the power from Chernobyl, went offline around 1989, indicating broader implications for Soviet military infrastructure. The decision to keep some reactors running post-accident reflects the complexities of energy management in the Soviet Union. Overall, the disaster had lasting effects on both the power grid and associated systems.
