Ignalina Nuclear Power Plant - similar to Chernobyl

[@kvrgagames5015]

Great video bro. You have a like from me. But there is something - It is Not necessarily a copy - there were differences the Chernobyl NPP consisted of four RBMK-1000 reactors each capable of producing 1000 MW of electrical energy The Ignalina NPP consisted of two RBMK-1500 reactors each capable of producing 1500 MW of electrical energy but following the Chernobyl nuclear disaster, they were de-rated to 1360 MW. These are the main differences, and who is interested in how the Chernobyl nuclear disaster happened, here you go: On April 25, 1986, shutdown for maintenance of the 4th power unit at the Chernobyl nuclear power plant was planned. Before the shutdown, an experiment and some other measurements were to be carried out. Due to a delay, further reduction of power was continued after 23:00, and the reactor was at 1600 MW then. At 00:05 on April 26, the power was at 720 MW. For some reason, most likely the switching off of the automatic regulator, the power fell to a near-zero level, and by 00:30, was around 50-70 MW and would be raised further. Now, the atmosphere in the control room was absolutely normal, it was only stressful to get the power to 200 MW, but once it did stabilize at 200 MW at around 01:00, the turbine was powered off and its oscillations were measured as one of the measurements to be taken before the shutdown. Then the final briefing was given and everyone went to their instruments. At 01:23:04 the turbine generator rundown experiment began. Everything was calm. At 01:23:40 the reactor was shut down at the end of the test. Power was no more than 230 MW when the emergency shielding (also used in normal situations like a routine shutdown) was engaged. However, instead of shutting down, a power surge occured and at 01:23:43 the power was at 500 MW. Then at 01:23:46 the active zone exploded. When the reactor is shut down, all of the control rods enter the active zone. However, the graphite extensions briefly introduce additional moderation, hence reactivity into the reactor system. The first shocks occurred when the rods were entering the active zone and the subsequent damage prevented their further entry. In 1983 at the Ignalina NPP a similar power spike occured when its Unit 1 was opened. But the rods managed to reach the bottom of the core and the reaction was stopped. But at Chernobyl the reactor was unstable at low power which was unknown to the operators at the time. So the control rods jammed upon shutdown and the active zone was destroyed, damaging the reactor building, and exposing it to the atmosphere.

Thank You

well the reason why the power fell is during the delay the reactor ran on half power now when an rbmk is running on full power or close to full power it burns away a poison called xenon but when it runs at half or below half power the reactor can get poisoned and during the delay that made the reactor become heavily poisoned so if the reactor is poisoned lightly or heavily the operators can slowly raise power how much time does it take to burn away all the poison it takes 24 hours but if you raise almost all or all the controls rods the power will make jumps until the reactor will be in a positive void coefficient now about the shutdown when A3-5 is initiated the control rods will start to be lowered very quickly but at the tips of the control rods is graphite now graphite accelerates power also the time to lower all the control rods takes 18 seconds that is quite a lot and when any rbmk reactor A3-5 is initiated the power is boosted for a bit so power jumps then lowers so during the test and when A3-5 was initiated the control rods started to lower graphite started to boost the power that made any left water molecule turn into steam that steam jammed the control rods in there position and there boron has not reached the core so the graphite is infinetly accelerating the power because it is stuck so yada yada yada the first explosion was due to the amount of steam in the core then the core was open so the hydrogen in the core mixed with oxygen now when hydrogen mixes with oxygen it explodes so yea that was the explanation of what is with the reactor what is its flaws what critical condition it is in

@@agnytevederyte1 That is the version of the story from HBO’s Chernobyl. The series is great, but there are a few historical inaccuracies. The story I wrote in my comment here is from A. Dyatlov’s 1994 interview, and it’s quite different from the HBO version.

Same Reactor as Chernobyl if I'm no mistaken. RBMK-1000 and was also used for interior shots for the Chernobyl miniseries by HBO

[@anatolylavrenty4405]

1:38 i dont know why but i always imagined these reactors much bigger than how they actually are

[@vantaaax]

oh trust me they are way bigger in person

[@krashd]

RBMK 1500s are a bit smaller than RBMK 1000s, despite being more powerful.

[@AntiShadman6969]

A beautiful plant which I'd love to visit at least once before it's completely gone, which I don't think I'll be able to do. Weird that I didn't see Beata in this video, the famous tour guide :) But there is an another group of beautiful people!

It's a shame they had to decommission it, while most Lithuanian supported nuclear power.

[@jonuxaspro1387]

THATS NOT SIMILIAR TO CHERNOBYL NPP. In Ignalina nuclear power plant there are 2 RBMK-1500 reactors. 😅

[@Krahamus]

RBMK 1500 is just more powerful compared to 1000, but everything else is the same, how it looks, operates, even if it has the same flaw which made Chernobyl to explode because graphite tips on rods.

No deberían poner musicales terror de fondo como si fuera algo malo, por eso la gente le teme a la energía nuclear por que siempre creen que va a explotar pero no, chernobyl fue un raro caso y eso pasó ya hace 30 años

Are they still using RBMK?!

Yes, Chernobyl one was RBMK 1000 Ignalina was using RBMK 1500, its basically identical besides being a bit more powerful, but from structure and flaw its still same.

[@overthetop-yv6ji]

Yes. RBMK´s are still in operation. Last one will be shutdown in 2050.

As amazing as these reactors are they are also horrible things capable of inflicting the worst kind of human suffering. They leave behind enormous problems at the end of their life and leave future generations decades of arduous clean up work.
