The catastrophic cascade at Chernobyl is set in motion.But if the plant itself loses power, then what happens? "The 700-plus pound steel blocks resting on top of the reactor core started rumbling around and being lifted into the air in the moments before the explosion.CNET también está disponible en español.Valery Legasov testifies before the commission, in front of the three power plant officials responsible for the disaster.In the RBMK reactor, it's the opposite: More steam results in higher reactivity. Harnessing the power of the atom and mitigating the risks of nuclear energy as best we can is one of the ways to a cleaner energy future.The only thing the plant workers could do was hit the emergency stop button. All but six of the 211-plus control rods have been removed from the core and the water is no longer providing any cooling effects. the water's ability to control neutrons is reduced, therefore the nuclear reactions increased. Control rods move in and out of the reactor, water is constantly pumped through to keep the whole thing cool and the power plant produces energy.At every step, Chernobyl touched on the ineptitude of Russian governance, the uncompromising courage of the liquidators tasked with cleaning up the site, the weight that hung over the shoulders of every scientist investigating the disaster and the stark reality of atomic power.The safety test is the starting point for a chain of errors which ultimately resulted in reactor 4's explosion.So we will continue to harness the power of the atom and we will get better. However, the team in the control room at Chernobyl attempted to do just that and disregarded the safety protocols in place.Moments after the reactor explosion, Chernobyl burns.A schematic of the plant used in HBO's Chernobyl showing the graphite core and the biological shields.The core is where the fission reaction takes place. By Sebastian Kettley. This forces all of the control rods back into the core. CHERNOBYL’S 1986 RBMK reactor explosion remains the single largest nuclear disaster in human history – but how did the Chernobyl nuclear explosion happen? as the reactor gets hotter, the cooling water expanded, causing voids in the water. Yes. The Chernobyl explosion tore the roof of the reactor’s building, flipped the reactor’s nuclear core and exposed the whole of Europe to radioactive isotopes. 4, was a huge 23 feet (7 meters) tall and almost 40 feet (12 meters) wide. Then, at 1:23:45 a.m., the explosion occurs. The term "positive void coefficient" gets thrown around and that's not a term you hear every day. But should we stop trying to do so? “There is some dispute among experts about the character of this second explosion but it is likely to have been caused by the production of hydrogen from zirconium-steam reactions.”This, in turn, jammed all of the control rods while they were only halfway down to the core.The pressure inside of the reactor then reached a critical point, destroying the rector and blowing off the 1,000-tonne reactor cover plate.This was a major design flaw found “in no other power reactors in the world”.When the safety test was initiated, the Chernobyl reactor was brought down to a power output of 720MWt, despite operations below 700MWt being strictly forbidden.“When the accident occurred the Soviet Union was using 17 RBMKs and Lithuania was using two.The exact details of what happened on the night of April 26 are forever lost to history but scientists have a very good approximation of how the incident unfolded.The reactor then proceeded to drop to around 500MWt before suddenly plummeting to just 30MWt.“Since the accident, the other three Chernobyl reactors, an additional Russian RMBK and both Lithuanian RBMKs have permanently shut down.”The Soviet reactor design emerged in the 1970s and according to the World Nuclear Association, “had several shortcomings” that played part in the 1986 disaster.“A number of significant design changes were made after the Chernobyl accident to address these problems.”The nuclear rector operates as a “light water graphite reactor” by boiling water in fuel channels to create steam, which then powers turbines and generates electricity.According to the association, the exposed reactor core released about five percent of its nuclear material into the atmosphere.“By the time that the operator moved to shut down the reactor, the reactor was in an extremely unstable condition.Chernobyl Power Plant in north Ukraine, near the border of Belarus and 81 miles (130km) from Kiev, housed four RBMK-1000 nuclear reactors.Chernobyl Nuclear Power Plant in northern Soviet Ukraine suffered a critical failure on April 26, 1986.
