Improving Safety at a Bulgarian Nuclear Power Plant Through Human Factors Engineering

摘要

In 1990, the International Atomic Energy Agency (IAEA) initiated the first phase of a major international program to assist eastern European countries in performing safety reviews of the WWER-440/230 nuclear power plants. The effort spanned a period of 15 months and included specialists from 21 countries assessing safety issues at plants in Bulgaria, Czechoslovakia, and the former USSR. Technical experts initially convened in February 1991 to gather detailed information provided by designers and operators in the USSR and to review original design concepts. This meeting was followed by a series of safety reviews conducted at four plant sites, during which time technical experts assessed specific plant design deficiencies as well as the overall of operations.
