An Evaluation of the Contractor. Assessment and evaluation of a power plant play an important role in either when the plants have been operating or in the electrical system planning. This all should be directed to fulfill the energy demand with better quality, sustainability and high economic competitiveness. The main problem that is usually faced by the utility is how to select the better performing plant in order to give more benefit. Performance of power plant could be measured by technical parameter, such as capacity factor. This paper describes how contractors are compared by means of the capacity factor of plants which they have constracted. The scope of this study are limited by the type of reactor, namely PWR (Pressurized Water Reactor) and PHWR (Pressurized Heavy Water Reactor). Literature study is used. The study covers 231 units which has accumulated 3,498 reactor years of nuclear power plant operation and also covers 10 main contractors in the world. The result are: for 400 -800 MWe class, KWU is the best contractor with capacity factor of 79.97%, and follow by SKODA (79.70%), AEE (76.56%), MHI (74.08%), AECL (71.79%), Westinghouse (71.64%), CE (71.37%) and DAE (48.54%). For 801- 1000 MWe class, MHI is the best contractor with the capacity factor of 83.42%, and follow by KWU (79.41%), Westinghouse (73.74%), AECL (71.87%), Framatome (71.03%), CE (67.80%), B&W (67.77%) and AEE (42.81%). For more than 1000 MWe class, where there are only 5 c9ntractors, MHI is again the best contactor with the capacity factor of 82.17%, and follow by KWU (79.72%), CE (74.85%), Westinghouse (67,93%), and Framatome (66.47%).
