Operation and maintenance of digital computer control system of KANUPP

The Karachi Nuclear Power Plant (KANUPP) employs dual-digital computer control systems for on-line plant control and for fuel handling control. Experience with operation and maintenance of these digital computer systems has proved the need for a third computer for each of the systems. These third computer systems are housed in the KANUPP Computer Centre and are used for training, as a source of tested spares, dynamic test facility for the repair of defective cards and for programme reassembly. An analogue computer system and mock-up of the plant control consoles have been interfaced with one of the digital computer systems to provide a facility for dynamic testing of control programmes under simulated plant conditions.
