Description of Core Power Distributionand calculations we have to derive an estimated value for each quantity subjected to limitation. We also estimate the uncertainty of the safety parameters. We investigate the main models forming the basis of reactor operation. The mentioned models are discussed in more details in Chap.?..

In-core instrumentation supplies raw data, which are processed, and finally reactor operator is provided with maps and logs. The present chapter describes detection methods, the elaboration of the detect

Description of Core Power Distribution). The present Chapter endeavors coining methods to determine the quantities limited by the mentioned equations. To this end we may use elaborated measurements and the attached calculations. A goal of limitations is to check local heat generation or the local power release. By means of measurements

Application of Trial Functions state is close to the actual core state. To account for the difference between the actual core state and the ideal state, we correct the ideal state by a set of functions, the so-called trial functions. The most important trial function is the ideal state supplied by the computational model. Furthe
