Energy and energy analysis of a PWR nuclear power plant

In this paper the energy and exergy analysis of a simulated pressurized light water reactor (VVER-440) 1375 MW thermal capacity nuclear power plant is presented. The plant was projected to construct in Libya. The objective of this study is to analyze the system units in its own and to determine the location having the largest exergy destruction and energy losses both energy and exergy formulations are developed for the system. The exergy destruction distribution indicates that the reactor, steam generator, and high-pressure turbine yield the highest exergy losses in the power plant. the largest losses of exergy in the plant occurs in the reactor which accounted for 86.5% followed by the steam generator and HPT which accounted for 6% and 8 of irreversibility respectively. In addition, the thermal and exergetic efficiencies of the power plant are (31.2%) and (38.54%) respectively.(author)
