On 11 October, 1991, reactor No. 2 caught fire, and was subsequently shut down. [28] Ukraine's 1991 independence from the Soviet Union generated further discussion on the Chernobyl topic, because the Verkhovna Rada, Ukraine's new parliament, was composed largely of young reformers. Discussions about the future of nuclear energy in Ukraine ...
Chernobyl Reactor 5 was initially abandoned after the 1986 disaster, but final decisions to halt work occurred in 1989 as safety and cost concerns grew. The Ukrainian government fully decommissioned the Chernobyl Nuclear Power Plant in 2000, closing down operations of the remaining active reactors and stopping any possible revival of Reactors 5 ...

Nikolai Fomin was the chief engineer of the Chernobyl Nuclear Power Plant at the time of the disaster in 1986. He arrived at the control room of reactor 4 at 4:30 a.m., about three hours after the initial explosion. He ordered the operators to keep pumping water into the reactor core, hoping to cool it down and prevent a meltdown.
The power station at Dodewaard was shut down in 1997. In 1997 the government decided to end Borssele's operating licence, at the end of 2003. In 2003 the shut-down was postponed by the government to 2013. [98] [99] In 2005 the decision was reversed and research in expanding nuclear power has been initiated.
Not all of the heat in a nuclear reactor is generated by the chain reaction that a scram is designed to stop. For a reactor that is scrammed after holding a constant power level for an extended period (greater than 100 hrs), about 7% of the steady-state power will remain after initial shutdown due to fission product decay that cannot be stopped.
When his wife died in 1959 after being injured from falling from a mountain and due to the same mountain blocking easy access to a nearby hospital in time, he decided to carve a 110-metre-long ...
