Abstract :
This stack monitor system Is a coordinated arrangement of hardware and software to monitor four hot cells (8 stacks) during the fuel dissection for the Proof-of-Breeding Project. The cell monitors, which are located In fan lofts, contain a microprocessor, radiation detectors, air flow sensors, and air flow control equipment. Design criteria Included maximizing microprocessor control while minimizing the hardware complexity. The monitors have been programmed to produce concentration and total activity release data based on several detector measurements and flow rates. Although each monitor can function independently, a microcomputer can also be used to control each cell monitor Including reprogramming If necessary. All programming is software, as opposed to firmware, with machine language for compactness in the cell monitors and Basic language for adaptability. In the microcomputer controller.
