In case of K-6, the time from I/F (July 1992) to C/O was 51.5 months. From the first concrete (Nov. 1992) to the first criticality (Dec. 1995), it took 37 months. The 40-month schedule is a aggressive target in comparison with the past U.S. construction experience(Before the TMI it was 60-70 months; after that, extended significantly) OECD NEA Workshop on Project and Logistics Management, Paris, 11th March 2014 12
