Microelectronics in quality control of nuclear power plant materials

General requirements are summed up for a control system for automated manipulators for testing materials of various components of WWER-440 nuclear power plants. They include the general purpose application of the control system for different types of manipulators, the possibility of independent manual and automatic control, the use of a microcomputer of domestic production, the use of a nonstandard keyboard allowing easy manual control and programming of the manipulator, the use of a tv camera monitor for communication with the microcomputer and for imaging the control operation sequence. The requirements for software are also given. All these requirements were implemented in a prototype of universal control unit RJM-01 based on a domestic production SM50/40-1 microcomputer. A block diagram is shown of the control system and a detailed description is presented. (Z.M.)
