The well-known equations for the production and decay of iodine and xenon-135 are utilized for predicting the variation of xenon poisoning in a nuclear reactor. Theae equations can be easily represented in an electrical analogue circuit, provided that the initial values of I and Xe are knowm. A xenon predictor designed in this manner can be modified so as to simulate the xenon poisoning in a reactor. The values of I and Xe are calculated at intervals on the basis of the reactor flux. It is assumed that the reactor flux is approximated to a constant value between the measurements. In the most unfavorable case, this stepby-step method will result in an amplitude error of max. 10 per cent of the equilibrium value of the xenon poisoning. (auth)
