OPR-1000
The OPR-1000 is a South Korean-designed two-loop 1000 MWe PWR Generation II nuclear reactor, developed by KHNP and KEPCO. The OPR-1000 was originally designated as the Korean Standard Nuclear Power Plant (KSNP), and was re-designated as the OPR-1000 in 2005 for foreign sales. It was developed based on the Combustion Engineering (C-E)'s system 80 design, through a technology transfer agreement. The reactor core design was derived from the C-E designed Arkansas Nuclear One Unit 2, the nuclear steam supply system (NSSS) was derived from the C-E designed units at Palo Verde Nuclear Generating Station, and auxiliary plant design was derived from the earlier Unit-1 and Unit-2 at the Yeonggwang (now Hanbit) Nuclear Power Plant.
Based on the OPR-1000 design, KEPCO has developed a Generation III reactor uprated plant, the APR-1400.
The reference plants used to develop the OPR-1000 design using technology transfer are Yeonggwang (now Hanbit) Unit-3 and Unit-4, which came on-line in 1995 and 1996, respectively. The first plants designated as OPR-1000 plants are Ulchin (now Hanul) Unit-3 and Unit-4, which came on-line in 1998 and 1999, respectively.
Korea Hydro & Nuclear Power (KHNP) states an improved OPR-1000 design has been implemented at eight units:
Including the reference Unit-3 and Unit-4 at Hanbit (formerly Yeonggwang), there are a total of twelve OPR-1000 plants, all inside South Korea.
The first plants incorporating the APR-1400 design are still under construction. Ten units are planned:
The first start of the OPR-1000 at Shin Kori Nuclear Power Plant Unit-1 was 28 February 2011.
This OPR-1000's first malfunction was noted on 2 October 2012 at 8:10 a.m. Shin Kori-1 was shut down after a warning signal indicated a malfunction in the control rod, which is used to control the rate of fission of nuclear materials, according to the Korea Hydro & Nuclear Power Co. It is the first time that reactor, located 450 kilometers southeast of Seoul, has been shut down due to a malfunction since it began commercial operation on 28 Feb. 2011. An investigation was undertaken to verify the exact cause of the problem.
