__NOTOC__ The OPR-1000 is a South Korean designed two-loop 1000 MWe PWR Generation II nuclear reactor, developed by KHNP and KEPCO.〔(【引用サイトリンク】title=OPR1000 )〕 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 partly on the Combustion Engineering (C-E) designs, 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+ uprated plant, the APR-1400. == Reactor fleet == 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: * Hanbit Unit-5 and Unit-6 (both on-line in 2002) * Hanul Unit-5 (on-line in 2004) and Unit-6 (on-line in 2005) * Shin Kori Nuclear Power Plant Unit-1 (on-line in 2011) and Unit-2 (on-line in 2012) * Shin-Wolsong Nuclear Power Plant Unit-1 (on-line in 2012) and Unit-2 (on-line in 2015) 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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「OPR-1000」の詳細全文を読む スポンサード リンク
