AbstractAbstract
[en] The article poses the question: What caused the Chernobyl accident? and puts forth a probable cause based on the design of the neutron absorber rods that control the RBMK reactor. The article is based on the presentation given by the Canadian Nuclear Society (CNS) president Dr. Jerry Cuttler at a special symposium entitled Chernobyl, The Legacy, held at the University of Toronto, April 27, 1996. The neutron absorber rods were not designed to accommodate the sequence of events that occurred prior to the accident, and modifications to the design were implemented based on the determination of the root cause of the accident. 3 figs

AbstractAbstract
[en] The effect of the Chernobyl accident on the future use of channel type reactors is discussed. Channel reactors in general, and the MKER-800 channel reactor design, are described. The MKER-800 is compared to five other types of reactors in terms of major technical aspects and economic indicators. The analysis shows that the MKER design is advantageous in practice

AbstractAbstract
[en] After implementing a series of safety measures, the Soviet nuclear engineers now believe that there is no possibility of a repeat of the Chernobyl accident sequence and there is some discussion of further development of the RBMK concept. The concept, with these safety measures, is examined and the advantages of the channel type uranium-graphite design noted. (author)

AbstractAbstract
[en] A standard classification for NPP maintenance equipment is suggested in compliance with the tasks: devices for machining, manipulators, technologjcal equipment, equipment for inspections checks. Besides, a classification for maintenance devices related to the RBMK-1000 reactor is suggested which includes 11 sets of the RITM devices. Schematics and descriptions are presented for equipment used in cutting pjpes of the upper tract, in cutting off level-butt welds and in removal of the process channel. Some data on pesults of modernization of the device are given

AbstractAbstract
[en] A mathematical model is proposed for calculating correction coefficients for neutron-measuring channels. The seven section channels (KNI-7 channels) monitor energy release in Russian RBMK-1000 reactors. KNI-7 channel lifetimes exceed the heat-releasing channel lifetimes in which they are installed. Therefore, KNI-7 channels are repositioned and require new correction factors. The calculation approach proposed accounts for the burnup history of direct charge detectors and heat-releasing channels by using values of the previously generated time-integrated detector current and energy production of heat-releasing channels. The computer program WIMS/DPZ was used to calculate the total correction factor as a product of two independent cofactors, and was found to perform satisfactorily. 4 refs., 3 figs

AbstractAbstract
[en] A device for fuel assembly cooling at the initial moment after the loss of flow in a channel-type RBMK boiling reactor is described. The assembly is closed with water stored in two vessels located one above another in the channel. By gravity the water pours over to the lower vessel through the siphon and then - to the assembly. The device allows to decrease the fuel temperature at the initial movement of accident down to 100 deg C
