Conclusions
The simple graphic method proposed for assessment of the operational safety of operating power-generating units of nuclear power plants makes it possible to:
take into account the safety history of each observed power-generating unit by constructing a safety plot the rating values over a fixed time interval;
analyze trends associated with the rating approaching the safety limit;
characterize the state of the first and second shielding level of the physical barriers;
reveal efficiently failures of normal operation which increase the probability of a serious accident and which require analysis of accident precursors;
use as the control limit on the safety plot the toerance limitR u, which makes it possible to regard, with high probability, any group of events for which the rating exceeds the limitR u as a precursor of a serious accident, since most rating values must be concentrated in the interval [0,R u]; and
use this approach, together with other methods for assessment of the operational safety of power-generating units, in the practice of safety assessment for licensing nuclear power plants.
