![]() ![]() The power stabilized at 200 MWt at around 1:00 am and did not rise further, due to continued xenon poisoning of the core.Ġ1:03 – Fourth cooling pump connected to right loop.Ġ1:19 – Shutdown signals blocked from steam-drum separators. He overrode Akimov’s and Toptunov’s objections, threatening to hand the shift to Tregub (the previous shift operator who had remained on-site), intimidating them into attempting to increase the reactor power. At the moment reactor power slipped to 30 MW thermal, he insisted the operators continue the test. ![]() The drop in reactor power from 1500 MWt to 30 MWt is disconcerting Akimov wants to abort the test, but is over-ridden by Dyatlov and forced to continue.Īnatoly Dyatlov, the deputy chief engineer, supervised the test. Now only one turbine was needed to take in the decreased amount of steam caused by the power decrease and turbine #2 was switched off.ġ4:00 – Under the normal procedures of the test the reactor would have been reduced to 30% power, but the Soviet electricity authorities refused to allow this because of an apparent need for electricity elsewhere, so the reactor remained at 50% power for another 9 hours.Įmergency core cooling system switched off.Ġ0:00 – Aleksandr Akimov, the unit shift chief in charge of the test takes over from Tregub, who stays on-site.Ġ0:28 – Control rods transferred from local to global control: Power plummets in the reactor further rods withdrawn. The purpose of the test was to observe the dynamics of the RMBK reactor with limited power flow.ġ3:05 – Twelve hours after power reduction was initiated the reactor reached 50% power. Slowly the operators began to reduce power for the test. Steam power was directed to both turbines of the power generators. The plants have safe and reliable controls that are protected from any breakdown with three safety systems.”Ģ7 March – Literaturna Ukraina (Ukrainian Literature) publishes an article written by Ms Lyubov Kovalevska (believed to be a senior manager at Chernobyl Nuclear Power Plant (NPP)) in which she writes that substandard construction, workmanship and concrete, along with thefts and bureaucratic incompetence are creating a time bomb “The failures here will be repaid, repaid over the decades to come”.Ġ1:00 – The reactor was running at full power with normal operation. “The odds of a meltdown are one in 10,000 years. ![]() In the Soviet Union it was customary for all sections of public employment to have their own special day, when they receive public acclaim for their work and are given extra bonuses.Īpril – The Minister of Energy, Anatoly Mayorets, decrees that information on any adverse effects caused by the functioning of the energy industry on employees, inhabitants and the environment, were not suitable for publication by newspapers, radio or television.įebruary – Vitali Sklyarov, Minister of Power and Electrification of Ukraine, in reference to the nuclear reactors in Ukraine, is quoted in Soviet Life magazine as saying: ![]() This news was reported by the media on 22 December, a festive day for workers in the energy industry. The EPS-5 button (top row, center) initiates rapid emergency shutdown (© sovietologist).ĭecember – The construction of Unit 4 at Chernobyl is completed and the plant becomes operational on the 20th. The six emergency shutdown switches from control room 1. The first of the Chernobyl Nuclear Power Plants four reactors is ready to operate followed by number 2 in 1978.Īccording to data held by the KGB, design deviations and violations of construction and assembly are occurring in the construction of the 2nd generating unit.Īpril – The Chernobyl Atomic Power Station reaches its first 10 billion kilowatt-hours of electical output. October – Filling of the cooling water reservoir for the Chernobyl Power Plant begins. For this reason it was decided to build the RBMK pressure tube reactors. The scientist Alekzandrov opposes this, saying that the RBMK- 1000 was not only the safest reactor, but it also produced the cheapest electricity as well. He informs the Ukraine Minister of Energy, Aleksei Makukhin, that an RBMK (a boiling water reactor) releases forty times more radiation than a PWR. Deputy Chief Engineer at Chernobyl, Grigori Medvedev, proposes construction of Pressurized Water Reactors (PWRs). Discussions take place in Kiev about the type of nuclear plant to be built at Chernobyl. ![]()
