A XENON POISON COMPUTER
In this computer, the variations of reactor power are recorded by a strip chart recorder, using conducting ink. On the occurrence of a shutdown, the chart is fed to an automatic curve foliower, having a chart speed much higher than that at which the chart was recorded. The curve follower output, which is propontional to the recorded power variations, is used as the driving function of an electronic analog computer operating on an accelerated time scale and synchronized with the curve follower, and this compotes the iodine-135 and xenon135 concentrations as a function of time, up to the moment of shutdown. The computer time scale is then further accelerated, and using the iodine and xenon concentrations previously computed as initial conditions, the buildup and decay of xenon after shutdown is calculated. The results are presented as a curve of reactivity absorhed by the poison against time. (auth)
