There are many countries, particularly in Asia, where strong electric demand and limited fuel availability make nuclear plants an important option. In the US, the Advanced Light Water Reactor (ALWR) program has successfully developed advanced designs by ABB-Combustion Engineering, General Electric and Westinghouse that are in various stages of the process of being licensed by the US Nuclear Regulatory Commission. The prospects for building these plants in the near future depend upon sales outside the US. At this time there is only one US-designed nuclear plant now in operation that was completely designed and built after the TMI era. This is the Yonggwang (YGN) Nuclear Power Plant Units 3 and 4 in the Republic of Korea. Design on this plant began in 1987. It is a true ``First of a Kind`` plant in that it has a unique layout and there is no single nuclear plant that provided a basis for the design. The design is an evolutionary extension of the lessons learned in the process of completing the newest of the US plants in the 1980`s. Although not required to be an ALWR plant, the YGN design incorporates most of the design criteria established for ALWRs. YGN 3 and 4 was constructed and started on schedule and is now operating reliably. YGN 3 was declared commercial 8 years after engineering started (64 months after the first structural concrete was poured). Four more units are now under construction in Korea using this basic design with two more in the early design stage. The schedule is being reduced for the follow-on units. As of February 1, 1996, YGN 3 had been commercial for 10 months and had operated 275 days, or about 90% of this time. YGN 4 has operated continuously since its commercial date of January 1, 1996 (three months ahead of schedule, 61 months after first concrete). This project provides a real-world benchmark for the construction of a new nuclear plant today.
