Computer code for determining primary diagnostic indexes for automatic monitoring system

The computer code is described for evaluating the primary diagnostic indexes of the automatic monitoring system that is part of the in-service diagnostics system of a nuclear power plant. Automatic monitoring of diagnostic signals envisages the measurement of the signals using a system comprising a selector and a fast A/D converter. A brief hardware description of the measuring system, the algorithm of operation, the method of function of the primary diagnostic indexes and the description of the code (written in Turbo Pascal version 5.0 under MS-DOS version 3.3 for an IBM PC) are presented.
