KINETICS EXPERIMENT USING AN IMPROVED DROP-ROD METHOD AT A TRIGA REACTOR

Two methods exist for analyzing the reactivity state of a research rea ctor, namely, the static and the dynamic method In the present work th e dynamic method is applied to the TRIGA Mark-II reactor, Vienna, by u sing the improved integral method and a new integral method with a com panion function. Both methods are used to analyze and calculate the ne gative reactivity of the reactor, taking into account the six groups o f delayed neutrons. The differences of the methods are discussed, and the systematic error is estimated.
