Investigation of the development of the 1986 accident at the Chernobyl nuclear power plant

Important results obtained from investigations of the diverse processes that occurred during the accident in the No. 4 unit of the Chernobyl nuclear power plant on April 26, 1986 are presented in a concise form. The events occurring in the unit in connection with the preparation for runout tests to be performed on a turbogenerator are examined: from the characteristics of the test program to the actions taken by the plant personnel in preparation for the these tests. The events that determined the character of the evolution and the catastrophic consequences of the accident are noted: involuntary stopping of the reactor and subsequent power increase without unpoisoning of the core, stopping of feed-water flow with increasing loop flow, operators’ lack of information about the actuation of the technological shielding of the electric drives of the main circulation pumps and electricity generator. Computational analysis of the initial phase of the accident and other computational assessments revealed new factors which with a large void effect made reactor runaway on prompt neutrons unavoidable-cavitation steam reaching the core entrance from the shutoff-regulation valve and/or the cavitation shutdown of the feed to the remaining main circulation pumps after the pumps powered by the run-out turbogenerator were disconnected. The most likely picture of the evolution of the accident is constructed on the basis of an examination of the destroyed power-generating unit. __________ Translated from Atomnaya énergiya,Vol. 100, No. 4, pp. 243–258, April, 2006.     

Underground nuclear power plant siting

This paper summarizes the results of investigations to define the design concepts and estimate cost penalties associated with the burial of large light-water reactor nuclear power plants in underground rock cavities. Several cavities are proposed to contain the major components of the power plant without requiring excessive spans. The cost penalty of the underground plant is estimated to be less than 10% above a similar surface plant in favorable geologic media. Preliminary analyses also indicate a potential improvement in containment of radioactive materials following a postulated accident.     

Uniterm low-capacity nuclear power plant

The results of development work on an innovative low-capacity nuclear power plant (LCNPP) Uniterm together with substantiation of the need for a technical design of a reactor system and the basic design of the power plant are presented. The results of the work are used to determine the power range of the power generating unit where the main consumer qualities are guaranteed to be attained. Economic assessments of the development and operation of a two-block LCNPP under conditions in Russia are presented. __________ Translated from Atomnaya énergiya,Vol. 103, No. 1, pp. 44–48, July, 2007.

The development of a thermal performance diagnostics expert systemfor nuclear power plant

This paper describes the development of a computerized Thermal Performance Diagnostics Expert System (TPDES) designed to assist performance engineers at nuclear power plant. The TPDES is the second phase product of the ChinShan plant performance Monitoring, Analysis and Diagnostics Expert System (CS-MADES) project. The objective of this system is to serve as a powerful tool in diagnosing the heat rate degradation problems found in nuclear power plant through man-machine intercommunications. The whole system framework was developed on a personal computer to provide an integrated, user-friendly and menu-driven environment in meeting the operator's requirements. Moreover, it can be actuated either in Chinese or English mode. Some visible benefits have been gained so far through the prototype system installed at the Chinshan nuclear power station. It is believed that TPDES could successfully reduce lost megawatts and save maintenance cost through the early detection of thermal performance deviations
