The targeted 24.5 months of commissioning time for the ongoing SKN unit #1 project in Korea is a tough challenge in view of saving at least 7 months from the previous 32 months for UCN unit #3 project that has been a prior version of OPR1000 and also the reference plant of this unit. Such commissioning time-saving has been made possible by introducing renovated technology, optimization of commissioning technique, and adoption of lessons-learned from the previous projects. Our experiences are discussed herein with respect to the scheduling of commissioning operation of previous NPP projects on a milestone basis, including trouble areas that could cause schedule delay and our approaches adopted for solving the key issues. In addition, this paper will introduce a summarized 24 month commissioning schedule which has been optimized to the most efficient level by reflecting the prior project experience, and applying the new techniques and methods.
