Resumen de Temperature data processing for nuclear power stations
Equipment is being designed primarily to meet specifications laid down by the Authorities responsible for nuclear power stations in Britain.
600 thermocouples must be scanned every 2 minutes and their readings stored for 10 minutes. Reference levels relating to the temperature and rate of change of temperature of each thermocouple must also be stored and alarms raised if any levels or rates are exceeded. Elaborate displays and print facilities are demanded. Above all, the equipement must be utterly reliable.
The equipment is being designed around available techniques of low level switching, drift corrected DC amplification, analog-digital and digital-analog conversion, magnetostriction delay storage, standard logical circuits, CRT displays and character tubes. Redundant equipment is used and automatically tested during each operation cycle. Electronics is almost entirely solid state and moving mechanical parts are avoided as far as possible.
The computer is fixed program at any one time but the program can be changed and the equipment is being designed so that it can be extended and can be used for other applications.
