Nikolay KARPAN From Chernobyl to Fukushima KIEV S. PODGORNOV 2012 BBC 63.3(2)7 K 21 Nikolay KARPAN K 21 From Chernobyl to Fukushima. — Kiev: S. Podgornov, 2012 — 304 p.: ill. ISBN 966-7853-10-5 In his new book - From Chernobyl to Fukushima - physicist and engineer Nikolay Karpan provides many earlier unknown facts on two major large-scale NPP accidents. With his long term practical experience of work at many different NPPs, including ten years of work at the Chernobyl NPP (1979 - 1989), Nikolay Karpan fully experienced all aspects of life of “liquidators of nuclear accidents”. The author provides an impressive accountof initial hours of these disasters and gives interesting analysis of these historical events. The description of contemporary state of international Chernobyl projects and his account how the Chernobyl tragedy was transformed into a farce will leave nobody indifferent. The events at Japanese Fukushima NPP are assessed from a professional point of view. For the first time the reader will see logical patterns in explosions of the Japanese reactors, associated with inadequate understanding of relations between the Man and the Nature with its mighty forces releasing in natural disasters. Safe nuclear reactors do not exist and they cannot exist, as in addition to high operational temperature and pressure they contain deadly radioactive loads that release to the environment far too often - every 15 years (four off-design accidents in 57 years of the global nuclear power industry’s history). The book is a major event as it is written by a professional physicist about extreme developments he experienced himself, the book written honestly, stingingly and without pathos.

ACCIDENT IS NOT OVER......................................................297 Foreword I never imagined that events of global significance may happen in my life, and that I would have to do a lot of hard work to remain a human being in this mess. The Chernobyl disaster swept like a massive roller across continents, countries, and on the fate of millions of people. Only Ukraine has lost half a million of its citizens (the book provides a documental proof of the fact), nothing to say about adverse health and economic impacts on its neighbours. Today, we can definitely say that even such superpower as the Soviet Union was not ready to accidents of the Chernobyl scale. Japan was not an exception either, suffering now from consequences of accidents at Fukushima NPP, which have not been fully revealed yet and can have very serious implications. So, the main thing I wanted to say to the reader of the book - it is unacceptable to have a blind faith in the power of the state and its apparatus. People should believe in themselves only and the should be able to pull themselves by hair out of any trouble. It is impossible to be indifferent to things that happen in my country of residence, which is called my Homeland. You can not allow incompetent officials and rulers of our lives to break us morally, as the Soviet Politburo did to Chernobyl staff. 5 List of Acronyms and Abbreviations A&UB - administrative and utility building APC - armoured personnel carrier Bq - becquerel, Bq is defined as the activity of a quantity of radioactive material in which one nucleus decays per second. Ci = 3.7xl010 Bq CC - Criminal Code. CCF - Chernobyl Commissioning Facility - a facility responsible for checking completed construction works and issuing work permit CCR - Central Control Room (of NPP) CE - Chief Engineer of the NPP. Ci - curie, a unit of radioactivity, 1 Ci = 3.7 x 1010 Bq CivDef - Civil Defence CMT - Crisis Management Team CoS - Chief of Staff - Senior officer of Civil Defence Unit CPSU - Communist Party of the Soviet Union CRCE - chief reactor control engineer CS - Chemical Section of NPP CSM - Chief Shift Manager CSS - control and safety system. CTCE - chief turbine control engineer. CUCE - chief unit control engineer (unit of NPP is a reactor, connected turbines and other machinery which works jointly with this reactor) DREG - program for diagnostic and registration of the Unit parameters. EDR - exposure dose rate EBRD - European Bank for Reconstruction and Development. ERCS - Emergency Reactor Cooling System (also known as ECCS - Emergency Core Cooling System) ERML - External Radiation Monitoring Laboratory. ES - Electric Section of NPP The first criticality - the first launch of a new reactor to check all associated systems GAEN - Soviet Nuclear Power Supervision Authority (the USSR State Committee for Nuclear Power Industry Supervision), earlier named GAN. Gy - gray (absorbed dose of radiation energy, 1 J/kg) IAE - Kurchatov Institute of Atomic Energy (Moscow) of the USSR Academy of Science INES - International Nuclear Event Scale, developed by IAEA in 1988. Since 1990, the scale was applied for uniform assessment of emergencies associated with radiation releases at NPPs. Later, the 6 scale was applied to all nuclear installations, associated with civil nuclear industry. KhTP - Kharkov Turbine Plant. MAC -maximal acceptable concentration MCA - maximal credible accident. MCP - main circulation pumps MFCC - multipass forced circulation circuit. MMMI - USSR Ministry of Medium Machine-building Industry (Ministry which was responsible for the Soviet A- bomb project and later for civil NPP program. Reorganised into the Ministry of Atomic Energy and Industry of the USSR in 1989) Mol - Ministry of Interior. MOX fuel - Mixed-Oxide fuel, containing oxides of several fissionable elements. The term is predominantly applied for mixtures of plutonium and uranium oxides (natural, enriched or depleted uranium). MOX fuel behaves similarly to the low enriched uranium oxide used as the conventional fuel of the majority of nuclear reactors (but not exactly in the same way). NIKIET - R&D Institute of Power Engineering of the USSR Medium Machine-building Industry. OCR - operator-controlled neutron absorbing rods. Politbureau - ruling board of the CPSU Central Committee, the actual supreme decision-making body of the USSR. R - roentgen, a unit of measure for exposure to ionizing radiation. 1 R is the amount of radiation required to generate one coulomb of ion pairs in one cubic centimetre of dry air at standard temperature and pressure (approx. 2.0819xl09 ion pairs) RBMK - Soviet-type graphite moderated reactor (all reactors of Chernobyl NPP were of this type) RCR - reserve (back-up) Control Room of a NPP unit rem - r-oentgen e-quivalent m-an: the amount of any ionizing radiation that has the same biological effectiveness as 1 rad of x-rays (see Sv below) RS - Reactor Section of NPP SDS - reactor shutdown system. Sv - sievert, unit of dose equivalent radiation.
