The 'Operating Instructions'

Photo credit: chidori@emptytriangle.com
Each entry aims to provide an exhaustive, chronological account of what is known and unknown about the particular episode being discussed. Body text without formatting is my own narrative explanation of events, meant to introduce italicized quotations from the various sources. To prevent the text from becoming entirely bloated and tangential, thematic sub-sections marked with thumbnail images will dive deeper into the details, provide technical explanations, or 'teach the controversy' of competing claims, theories and explanations. An expeditious reader is expected to simply skip over these marked-out sections, consulting them only as needed.

Yuri Tregub:
 
БЩУ дрожал. Но не как при землетрясении. Если посчитать до десяти секунд - раздавался рокот, частота колебаний падала. А мощность их росла. Затем прозвучал удар. Киршенбаум крикнул: "Гидроудар в деаэраторах!" Удар этот был не очень. По сравнению с тем, что было потом. Хотя сильный удар. Сотрясло БЩУ. И когда СИУТ крикнул, я заметил, что заработала сигнализация главных предохранительных клапанов. Мелькнуло в уме: "Восемь клапанов... открытое состояние!" Я отскочил, и в это время последовал второй удар. Вот это был очень сильный удар. Посыпалась штукатурка, все здание заходило... свет потух, потом восстановилось аварийное питание. Я отскочил от места, где стоял, потому что ничего там не видел. Видел только, что открыты главные предохранительные клапаны. Открытие одного ГПК - это аварийная ситуация, а восемь ГПК - это уже было такое... что-то сверхъестественное... Единственное - у нас была надежда, что это ложный сигнал в результате гидроудара.
 

Technical Explanations: My intended audience is made up of readers who are familiar with the subject and have been exposed to various articles, documentaries or some of the most popular non-fiction books. Therefore I will not take the time to explain the basics of how reactors produce electricity, but more complex topics such as reactivity coefficients and Operating Reactivity Margin will warrant a concise summary. The lowest level of assumed knowledge would be viewers of HBO's Chernobyl miniseries, provided they paid close attention to Legasov's courtroom explanation in Episode Five.
 
Human Factors: Too often, the most reliable sources relate what happened prior to the accident, while neglecting the why. We don't learn the rationale behind the decisions that were made, and what April 26th looked like from the perspective of the participants. Conversely, the worst sources make baseless claims or twist the narrative to supply this very information. In this category I will attempt to provide the non-hindsight version of the accident.
 
Controversies: We know almost everything we need to know about what happened that night. But blank spots remain, and sources conflict. In the spirit of full disclosure and academic inquiry, this category will attempt to inform the reader of competing claims, theories and potentially true explanations for what happened.

Myths/Misinformation: At other times the sources conflict, but the facts themselves are not ambiguous. Here the record can simply be corrected, with an eye to combating well-worn canards that have long sought to scapegoat individuals or spice up the narrative.

Key Sources Cited

Yuri Scherbak, Chernobyl, 1991

This book by epidemiologist-journalist-statesman Yuri Scherbak contains numerous interviews with direct participants of the accident, including several members of the night shift. These interviews were conducted quite soon after the events themselves, by an author who could not have had enough knowledge to color the subjects' words with his own agenda. For that reason this text can be relied on to a greater degree than similar testimony given to journalists decades after the fact. ISBN: 5-265-01415-2

Nikolai Karpan, Revenge of the Peaceful Atom, 2006

Like Scherbak, Karpan chased down many of the engineers who were on duty that night to record their stories. Unlike Scherbak, Karpan was interviewing his own former colleagues, and as Deputy Chief Engineer for Science at ChNPP possessed a formidable knowledge of the accident's technical aspects. Crucially, this book contains transcripts of the 1987 criminal trial, although it is still unclear how these texts came to be. ISBN: 9668135210

Razim Davletbaev, The Last Shift, as published in Chernobyl, Happenstance or Inevitability, ed. A. N. Semenova, 1995.

This account by a turbine division supervisor covers almost the entire period in question, addressing both human interactions and technical details.

IAEA, The Chernobyl Accident, Updating of INSAG-1, 1993

Although not a primary source, the so-called INSAG-7 report is the definitive document describing the technical aspects of the accident. It provides essential context for the events of 26 April 1986 while often sidestepping the human factors at play. Nikolai Karpan was a contributing author to Annex I, which is in fact the driving force behind the report. ISBN 92-0-104692-8

Anatoly Dyatlov, Chernobyl. How it Was, 1995

While it would be foolish to approach this book uncritically, the memoirs of the Deputy Chief Engineer must be allowed to enter into a dialog with the other sources. Dyatlov also interviewed his former colleagues in certain passages, and his accounts are corroborated more often than not. For what it may be worth, none of his fellow survivors have sought to debunk this version of events. ISBN 5-93728-006-7

Grigori Medvedev, Chenobyl Notebook, 1987

This is something of an anti-citation, since a more unreliable and dishonest book about Chernobyl has yet to be written. However, many of the myths this site seeks to combat were initially popularized by this book, which is regrettably the most influential English-language source on the accident. Many sources by Western authors have been compromised by citing Medvedev. ASN B00515LT2M
