Any questions

00:00:03.797 --> 00:00:07.073

No Continue please

00:00:08.633 --> 00:00:10.749

To test this theory

00:00:10.083 --> 00:00:13.667

the reactor is placed in a reduced power mode

00:00:13.746 --> 00:00:15.265

700 megawatts

00:00:15.346 --> 00:00:17.823

to simulate a blackout condition

00:00:17.903 --> 00:00:19.741

Then the turbines are turned off

00:00:19.821 --> 00:00:21.739

and as they slowly spin down

00:00:21.818 --> 00:00:23.537

their electrical output is measured

00:00:23.617 --> 00:00:27.133

to see if it's enough to power the pumps

00:00:27.213 --> 00:00:29.371

The science is strong

00:00:29.451 --> 00:00:34.286

but a test is only as good as the men carrying it out

00:00:35.525 --> 00:00:38.801

Now the first time they tried they failed

00:00:38.882 --> 00:00:41.519

The second time they tried they failed

00:00:41.599 --> 00:00:44.156

The third time they tried they failed

00:00:44.237 --> 00:00:47.114

The fourth time they tried

00:00:47.193 --> 00:00:51.189

was April 26th 1986

00:00:01.000 --> 00:00:05.021

وكل ما ورد في هذا المستند كان كذب ا

00:00:05.003 --> 00:00:08.017

لتوقيع هذه الشهادة

00:00:08.025 --> 00:00:12.063

يجب أن ت جرى كل اختبارات الآمان بنجاح

00:00:12.071 --> 00:00:15.084

لكن كان هناك واحد لم يتم إجراؤه

00:00:17.088 --> 00:00:23.001

يولد المفاعل النووي الحرارة في القلب هنا

00:00:23.013 --> 00:00:25.034

توجد مجموعة من المضخات هنا وهنا

00:00:25.042 --> 00:00:28.088

تضخ الماء باستمرار إلى القلب

00:00:28.096 --> 00:00:31.042

تحول حرارة القلب المياه إلى بخار

00:00:31.005 --> 00:00:33.088

الذي بدوره ي دو ر التوربينة هنا

00:00:33.096 --> 00:00:36.025

ما ينتج عنه الكهرباء

00:00:36.034 --> 00:00:40.003

لكن ماذا لو لم تكن المحطة مزودة بالطاقة

00:00:40.096 --> 00:00:44.055

ماذا لو تعرض فيض الكهرباء المتوجه إلى المحطة لاضطرابات

00:00:44.063 --> 00:00:47.017

ماذا لو حصل انقطاع في التيار أو تعطلت أحد الأجهزة

00:00:47.025 --> 00:00:50.997

أو هاجمنا عدو خارجي

00:00:50.013 --> 00:00:51.092

إن لم تكن هناك طاقة

00:00:52.000 --> 00:00:54.088

فلا يمكن للمضخات نقل المياه عبر القلب

00:00:54.096 --> 00:00:57.075

ومن دون المياه ترتفع حرارة المفاعل

00:00:01.000 --> 00:00:02.000

Des questions

00:00:03.068 --> 00:00:04.076

Non

00:00:05.036 --> 00:00:07.008

Poursuivez je vous prie

00:00:08.056 --> 00:00:10.002

Pour tester cette théorie

00:00:10.092 --> 00:00:13.056

le réacteur doit fonctionner à puissance réduite

00:00:13.008 --> 00:00:15.024

à 700 mégawatts

00:00:15.048 --> 00:00:17.008

pour simuler une rupture d'alimentation

00:00:18.999 --> 00:00:19.006

Les turbines sont éteintes

00:00:19.084 --> 00:00:21.006

et pendant qu'elles ralentissent

00:00:21.084 --> 00:00:23.048

on mesure leur production d'électricité

00:00:23.072 --> 00:00:27.012

pour voir si elle suffit à alimenter les pompes

00:00:27.036 --> 00:00:28.072

La science est bonne

00:00:29.068 --> 00:00:31.092

mais la réussite d'un essai dépend surtout

00:00:32.016 --> 00:00:34.004

de la compétence de ceux qui l'effectuent

00:00:35.044 --> 00:00:38.036

A leur premier essai ils ont échoué

00:00:39.999 --> 00:00:41.028

A leur deuxième essai ils ont échoué

00:00:41.052 --> 00:00:43.096

A leur troisième essai ils ont échoué

00:00:44.048 --> 00:00:46.028

Et leur quatrième essai

00:00:47.002 --> 00:00:50.052

a eu lieu le 26 avril 1986

00:00:01.000 --> 00:00:02.639

Irgendwelche Fragen

00:00:03.088 --> 00:00:07.556

Nein Fahren Sie fort bitte

00:00:08.056 --> 00:00:13.874

Um dies nachzuweisen wird zunächst die Reaktorleistung abgesenkt

00:00:13.096 --> 00:00:17.051

bis auf 700 Megawatt Dann simuliert man den Stromausfall

00:00:17.006 --> 00:00:20.035

Dazu stellt man die Turbinen ab

00:00:20.012 --> 00:00:23.796

und während sie langsam auslaufen wird die erzeugte Spannung gemessen

00:00:23.092 --> 00:00:26.833

um zu sehen ob sie ausreicht um die Pumpen zu versorgen

00:00:26.092 --> 00:00:29.435

Die Theorie leuchtet ein

00:00:29.008 --> 00:00:35.000

Aber ein Test ist nur so gut wie die Männer die ihn durchführen

00:00:35.004 --> 00:00:41.051

Der erste ihrer Versuche schlug fehl Auch ihr zweiter Versuch schlug fehl

00:00:41.068 --> 00:00:44.479

Sogar ihr dritter Versuch schlug fehl

00:00:44.056 --> 00:00:51.016

Ihr vierter Versuch schließlich war am 26 April 1986

00:00:01.000 --> 00:00:05.374

00:00:01.000 --> 00:00:03.019

Для подписания этого документа

00:00:03.486 --> 00:00:07.624

должны были быть успешно завершены все испытания

00:00:07.799 --> 00:00:09.701

И все же одно оставалось

00:00:13.029 --> 00:00:14.697

Атомный реактор

00:00:15.014 --> 00:00:17.208

генерирует тепло в активной зоне

00:00:18.259 --> 00:00:20.032

Ряд насосов здесь и здесь

00:00:20.537 --> 00:00:23.506

посылает через нее постоянный поток охлаждающей воды

00:00:24.174 --> 00:00:26.509

Тепло активной зоны превращает воду в пар

00:00:26.776 --> 00:00:28.837

пар вращает турбину здесь

00:00:28.953 --> 00:00:30.722

и вырабатывает электричество

00:00:31.481 --> 00:00:34.184

Но что если на электростанции нет электричества

00:00:36.052 --> 00:00:38.838

Что если отключено электричество питающее станцию

00:00:39.781 --> 00:00:41.241

Обесточивание

00:00:41.305 --> 00:00:44.999

отказ оборудования или нападение врага

00:00:45.278 --> 00:00:46.871

Если нет электричества

00:00:47.999 --> 00:00:49.751

насосы не могут качать воду через активную зону

00:00:50.333 --> 00:00:52.335

А без воды она перегревается

00:00:01.000 --> 00:00:05.481

Preguntas No

00:00:05.641 --> 00:00:07.561

Siga por favor

00:00:08.006 --> 00:00:10.088

Para comprobar esa teoría

00:00:11.999 --> 00:00:15.241

se reduce la energía del reactor a 700 megavatios

00:00:15.004 --> 00:00:20.002

para simular un apagón Entonces se apagan las turbinas

00:00:20.036 --> 00:00:23.056

y mientras van girando lentamente se mide la electricidad

00:00:23.721 --> 00:00:27.032

para ver si es suficiente para bombear

00:00:27.048 --> 00:00:29.601

Científicamente funciona

00:00:29.761 --> 00:00:35.044

pero una prueba solo es tan buena como quienes la realizan

00:00:35.006 --> 00:00:38.088

La primera vez que la hicieron fallaron

00:00:39.999 --> 00:00:44.561

La segunda vez fallaron La tercera vez fallaron

00:00:44.721 --> 00:00:51.004

Y la cuarta vez que lo intentaron fue el 26 de abril de 1986

Movie Summary

In April 1986, an explosion at the Chernobyl nuclear power plant in the Union of Soviet Socialist Republics becomes one of the world's worst man-made catastrophes.
