INVESTIGATION OF RESEARCH ACTIVITIES ABOUT THE CHERNOBYL NPP ACCIDENT IN BELARUS, UKRAINE AND RUSSIA

在项目过程中，Imanaka访问了白俄罗斯、乌克兰和俄罗斯从事切尔诺贝利核电站事故科学研究的各种机构：2000年三次，2001年两次，2002年两次。通过与正在研究切尔诺贝利的科学家的讨论，Imanaka发现了许多有趣的作品，并要求他们为这个项目准备专门的论文。22篇论文和一篇由Imanaka撰写的论文发表在技术报告Kurri-KR-79中(2002年7月)。它被认为是关于事故各个方面的切尔诺贝利文件的独特集合。在讨论和通过该项目获得的材料的基础上，Imanaka发表了几篇关于切尔诺贝利事故的论文，涉及从30公里区域撤离的居民的外部剂量评估、切尔诺贝利1-4反应堆的核偏移过程、摧毁反应堆的爆炸的真实性质等方面。此外，苏联共产党中央委员会在事故发生后刚刚成立的处理事故后果的特别小组的协议从俄语翻译成日语。

In the course of the project Imanaka visited various institutes in Belarus, Ukraine and Russia which are engaged in scientific researches about the Chernobyl NPP accident: three times in 2000, two times in 2001 and two times in 2002. Through the discussion with scientists who are studying Chernobyl, Imanaka found a lot of interesting works and asked them to prepare special papers for this project. Twenty two papers together with one by Imanaka were published in a technical report, KURRI-KR-79 (July 2002). It is appreciated as a unique collection of Chernobyl papers concerning various aspects of the accident. On the basis of discussion and materials obtained through the project, Imanaka published several papers about Chernobyl accident concerning such aspects as the assessment of external dose to inhabitants evacuated from the 30km zone, the process of nuclear excursion of the Chernoby1-4 reactor, the real nature of the explosion that destroyed the reactor etc. In addition protocols of the special group, which was formed just after the accident in the central committee of the Communist Party of USSR to cope with the consequences by the accident, were translated from Russian to Japanese.
