A new method of calculating sensitivity coefficients of core characteristics relative to infinite-dilution cross sections has been developed. Conventional sensitivity coefficients are evaluated for the changes of effective cross sections which are dependent on individual models of core and cell. Therefore a correction has been derived to the conventional sensitivity coefficients based on the perturbation theory. The accuracy of the present method has been verified by comparing numerical results of sensitivity coefficients with a reference Monte-Carlo method.

The transition from emergency to existing exposure situation is an important stage in the nuclear or radiological emergency plan. It requires arrangements to be put in place and to be implemented so as to ensure that the transition is made in a coordinated and orderly manner of guidelines for adjusting the undertaken protective actions and other response actions. The delivering radiation doses to public and environmental pollution are monitoring that measurements should be implemented according to certain plan of intervention and protective actions in the different stages of the N/R accident. In this study, a computer model (RASCAL) is used to calculate the effect of severe accident could have detected on an operating nuclear power reactor PWR and the possible impact on the public. Features for the decision to implement the transition from emergency to existing exposure situation are proposed depending on the estimation of the collection of deliver exposure doses to the public and environment due to monitoring the different radiation sources resulting from the N/R accident.
