Abstract
The paper discusses a well-known condition [95%/95%], which is important for monitoring some limits of core parameters in the course of designing the reactors (such as PWR or VVER). The condition ensures the postulate ?there is at least a 95 % probability at a 95 % confidence level that? some parameter does not exceed the limit. Such conditions are stated, for instance, in US standards and IAEA norms as recommendations for DNBR and fuel temperature.
