Abstract

This paper considers two interrelated issues and – proceeding from the conditional probability concept and Bayes’ statistical theorem – suggests a universal method to process measured data with account of prior information available. To assure reliable reactor operation, at the design stage it is suggested to account for errors of subsequent control measurements while assessing the engineering margin factors for reactor parameters to be measured.

Kurzfassung

Um einen zuverlässigen Reaktorbetrieb zu gewährleisten, ist es notwendig schon in der Designphase bei der Festlegung der Fehlerspanne für im Betrieb zu messende Reaktorparameter die Fehler dieser Messung zu berücksichtigen. Hierzu wird ein Verfahren vorgestellt.
