6.1.2 TECHNICAL AND ECONOMIC PARAMETERS


This section presents some technical and economic parameters of NPP Bohunice and NPP Mochovce in operation.

UNIT CAPABILITY FACTOR

Unit Capability Factor - UCF is a WANO parameter that expresses the percentage ratio of electricity actually generated on unit and energy the unit would be able to generate within the given time interval, accounting for external limiting influences (power regulation by control center, etc.). The lower coefficient values for unit 1 and 2 were due to extended overhauls to implement safety improvements - in 1996 through 2000 (see diagram 6.1.2.a.) and table 6.1.2.b.). Note: Unit 1 at Mochovce was on trial operation in 1998 and was actually only operated during approximately a single quarter.

LOAD FACTOR - COEFFICIENT OF UTILISATION


The load factor accounts for the actual supplies of electricity in relation with electricity supplies to the grid that are possible, with not accounting for external limiting factors (power regulation by control center etc.). The lower values of the load factor of the Bohunice units achieved were significantly influenced by control center requirements on power regulation and extended overhauls under the Gradual upgrading of NPP V-1 units (see diagram 6.1.2.c.) and table 6.1.2.d.).
