A low frequency of unplanned scrams is a key indicator of the effectiveness of plant operations at an operating nuclear power plant. Operating costs, another indicator, are affected by scram frequency. By focusing management, operator, and technician attention (and resources) on certain high-risk plant components, significant improvements in scram frequency are possible. One method of identifying high-risk components is to study past scrams from plants similar to the one of interest. A complementary approach, of which Guardian is an example, is to develop a list of the plant's single failure points. This is a list of plant components, each of which can be in a state that would cause scram irrespective of the status of other components. The advantages of the Guardian approach include its ability to consider plant-specific factors, its ability to track day-to-day changes in plant configuration (i.e., test or maintenance activities in progress), and its ability to identify sources of unplanned scrams before they happen.
