Lessons of the Chernobyl Nuclear Accident for Sustainable Energy Generation: Creation of the Safety Culture in Nuclear Power Plants Around the World

The September 11, 2001 terrorist attack on the World Trade Center and subsequent events has effected perceptions of the terrorist threat to the U.S. in general, and nuclear power plants in particular. These concerns have given rise to calls by government and private orga nizations for reevaluations of both the nature of the threat and protection against it. This paper suggests a general framework for a balanced approach to these reevaluations and highlights some practical and cost effective approaches for improving nuclear power plant safeguards protection.

Causes Of Failure

In accordance with GOST 20911–89. Technical diagnostics search for the place and causes of failure is the main or one of the main tasks of technical diagnostics of objects. Published information on accidents and incidents is an effective search tool. The base of TOP FAILURES at the nuclear power plants of the world for the 70-year period of operation numbering over 900 cases published in the press is used. The analysis of cases related to the failure of structures, including protective shells, performing the most important function of the final fourth safety barrier of nuclear power plants. Examples of accidents and incidents with protective shells of nuclear power plants with VVER and their safety systems are given.

The basic method of the operational inspection of metal of heat exchanging tubes (HET) of steam generators (SG) is eddy-current multifrequency method all over the world. The greatest distribution was received variant with eddy-current testing (ECT) by use of a bobbing probe on the Russian nuclear power plants (NPP). Tubes with the defects which a subject to plugging are defined by results of lead operational ECT over the certain algorithm. SG resource is settled and replacement is required at achievement of a limit on number of the plugged tubes [1].
