Floorplans error or actual inaccessible rooms?

Looking at the floorplans, there are 4 rooms on the north side of unit 4, similar to unit 3, designated "1316" and "1317"

but here is the question, If you notice, these 4 rooms compared to the other ones of the same level don't have have a door where you could access them

So, is this a floorplan design error where they either forgot to add or they later added to the actual building? or were those rooms really inaccessible? because according to the info, these rooms had a role seen in the picture 3

A speculation From Sasha Zelentsov

It appears that Khodemchuk's colleague, Aleksandr Zelentsov, believes there is a possibility that Khodemchuk's body was found by firefighter Khmel while he was checking if the fire had been extinguished. Allegedly, Khmel found a body that would have belonged to Khodemchuk and called for his colleagues, but they soon lost consciousness due to the intense radiation. The search for Khodemchuk was later called off at the request of Natalia Khodemchuk.

Personally, I don't believe in this possibility, especially noting that Grigorij Khmel never testified to this.

Do you believe in this possibility?

Radiation levels in Pripyat

What were the radiation levels in Pripyat at the time of the accident? I am trying to find archival documents that talk about the radiation levels of the city 10-20 minutes after the accident. The city was only 10-15 miles away from the plant. If you lived in an apartment complex closest to the plant, say 10 miles away, what would be your dose if you were standing outside in the elements after the explosion?

1977 Soviet brochure about the Chernobyl Nuclear Power Plant

elib.biblioatom dot ru/text/chernobylskaya-aes-s-reaktorom-rbmk-1000_1977/

^((Reddit doesn't allow .ru links, so you'll have to fix the url yourself))

Published in 1977 by the Ministry of Energy and Electrification, along with the Soviet atomic energy agency, Glavatomenergo. Designed by the Special Experimental Art and Design Department for the Industry Exhibition Center.

Lots of cool pictures as well as general and technical information about the power plant. Google-translated version here.

Ruptured Fuel Channel

A picture of a ruptured fuel channel inside the Reactor Core. My question is how do they even replace or repair something like this? Isn’t the Graphite Stack highly radioactive? If Im right fuel channel rupture once happened in Leningrad NPP and probably somewhere else too during the era of operating these reactors? Also during the test they did in Chernobyl Reactor 4 before the test even ended many channels were ruptured right, and when they pressed AZ-5 almost all of them ruptured ( Including Control Rod Channels ) making it impossible for the control rods to even insert?

Why is the SDP corridors / 701-801 and it's equipment are almost never talked about when it comes to topics regarding the safety of the reactor?

The safety features of the RBMK-1000 are often discussed and theorized for more info regarding the disaster and what could had been done to the design.

Then we got the Room 701 and 801, an entire room dedicated for pipelines that involves the safety of the reactor which is connected to the Steam drums separators (Which in the floorplans info is refered to as "Steam discharge pipelines") and relieves steam to somewhere inside the building in case of steam overpressure (as I heard from posts I have asked regarding this room before), which were also connected to the MSV (Main safety valves).

So being that the case, Why Specialists on the reactor almost never mention it when they're discussing it's safeness unless you specifically ask about it? Was it a minor feature? is it due to the lack of info for certain reasons?

Hello, why are there so many masks in the buildings in Chernobyl?

I just joined Reddit, and I've always wondered about that. I consider myself someone interested in Chernobyl, though I don't know as much as people who have been into the subject for years.

Ich war dort. Ich weiß nicht, wer bei den technischen Details recht hat. Ich weiß nur, was ich gesehen und durchlebt habe. Die Strahlung war real. Die Angst war real. Und wir haben einfach unseren Job gemacht.

Ich bin ein ehemaliger Tschernobyl-Liquidator. Ich arbeitete in den ersten Wochen nach der Katastrophe im Mai 1986 in der Zone. Jahrzehntelang sprach ich nie über das, was ich dort sah und erlebte. Jetzt habe ich beschlossen, meine vollständige Geschichte auf Medium zu veröffentlichen.

In meinem Bericht beschreibe ich:
- Wie ich mobilisiert und nach Tschernobyl geschickt wurde
- Wie das Leben in der 30-Kilometer-Sperrzone war
- Meine Begegnungen mit Radioaktivität und kontaminierten Geräten
- Die Stimmung unter den Arbeitern
- Was man uns sagte – und was man uns nicht sagte

Ich teile dies, weil persönliche Zeugnisse wie meines verschwinden. Wir Liquidatoren werden älter, und nur wenige von uns sind noch übrig. Ich möchte, dass die Menschen wissen, was wirklich geschah.

**Ein kurzer Auszug aus meiner Geschichte:**

Am 25. Mai 1986 wurde ich geschickt, um Wasser aus den Kellern des Transporttunnels der Reaktoren 3 und 4 abzupumpen. Die Strahlenbelastung am Eingang betrug 50 Röntgen pro Stunde. Man sagte uns, wir hätten 15 Minuten Zeit, um die Aufgabe zu erledigen. Mein Team arbeitete 45 Minuten. Die Pumpe überhitzte und blockierte. Wir überlebten. Meine Dosis für diesen Tag wurde mit 11,5 Röntgen aufgezeichnet, aber die tatsächliche Dosis war viel höher.

Dies ist nur eine Episode. Die vollständige Geschichte ist viel länger und detaillierter. Ich schrieb alles auf, damit die Menschen nicht vergessen, was wirklich geschah.

What They Don't Tell You About Chernobyl: A Liquidator's Personal Account

I am a former Chernobyl liquidator. I worked in the zone during the first weeks after the disaster in May 1986. For decades, I never spoke about what I saw and experienced there. Now I have decided to share my full story on Medium.

In my account, I describe:
- How I was mobilized and sent to Chernobyl
- What life was like inside the 30km exclusion zone
- My encounters with radiation and contaminated equipment
- The atmosphere among the workers
- What we were told — and what we weren't told

I'm sharing this because personal testimonies like mine are disappearing. We liquidators are getting older, and few of us are left. I want people to know what really happened.

**A short excerpt from my story:**

On May 25, 1986, I was sent to pump water from the basements of the transport tunnel of reactors 3 and 4. The radiation level at the entrance was 50 roentgens per hour. We were told we had 15 minutes to complete the task. My team worked for 45 minutes. The pump overheated and jammed. We survived. My dose for that day was recorded as 11.5 roentgens, but the real dose was much higher.

This is just one episode. The full story is much longer and more detailed. I wrote it all down so that people would not forget what really happened.

Что не рассказывают о Чернобыле: личный рассказ ликвидатора

Я бывший чернобыльский ликвидатор. Я работал в зоне в первые недели после катастрофы в мае 1986 года. Десятилетиями я никогда не говорил о том, что видел и пережил там. Теперь я решил опубликовать свою полную историю на Medium.

В моём рассказе я описываю:
- Как меня мобилизовали и отправили в Чернобыль
- Какой была жизнь внутри 30-километровой зоны отчуждения
- Мои встречи с радиацией и заражённой техникой
- Атмосферу среди рабочих
- Что нам говорили — и чего не говорили

Я делюсь этим, потому что такие личные свидетельства исчезают. Нас, ликвидаторов, становится всё меньше. Я хочу, чтобы люди знали, что происходило на самом деле.

**Короткий отрывок из моей истории:**

25 мая 1986 года меня отправили откачивать воду из подвалов транспортного тоннеля реакторов 3 и 4. Уровень радиации на входе составлял 50 рентген в час. Нам сказали, что у нас есть 15 минут на выполнение задачи. Моя команда работала 45 минут. Насос перегрелся и заклинил. Мы выжили. Моя доза за этот день была записана как 11,5 рентген, но реальная доза была намного выше.

Это всего один эпизод. Полная история намного длиннее и подробнее. Я записал всё это, чтобы люди не забыли, что произошло на самом деле.

Is there any country that uses reactors still capable of a chernobyl style nuclear disaster?

We know that safety standarts have vastly increased since Chernoby. However, these improvements tend to not be equal everywhere. This has led me into thinking. Is there any country that due to techonological limitations, corruption, resource resctrictions or any other reason that has a nuclear reactor design fundamentally flaud enough where there is a non-trivial risk of having an accident similar to Chernobyl? If so which one would it be? One that comes to mind might be North Korea.

Edit: By similar to Chernobyl I meant releasing similar quantities of radiation to the Open. It doesnt have to be through that same specific flaw.
