Description

Reactivity coefficients and effects are discussed required for monitoring and predicting reactivity worths during reactor KS-150 operation. The temperature coefficients of the fuel and the moderator and reactivity coefficients of nuclear impurities are given. The effects of 135Xe and 149Sm poisoning, fuel burnup and of refuelling on reactivity are given. The Nordheim curve is shown and reactivity balanced for the nominal state. The control rod characteristics necessary for reactivity balance are shown. (author)
