Source-derived summary

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.

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.

Notes

The first plants incorporating the APR-1400 design are still under construction. Ten units are planned:

Unit-1 and Unit-2 at Shin Hanul Nuclear Power Plant in South Korea

Unit-3, -4, -5 and -6 at Shin Kori Nuclear Power Plant in South Korea

Unit-1, -2, -3 and -4 at Barakah Nuclear Power Plant in the United Arab Emirates.

History

The first start of the OPR-1000 at Shin Kori Nuclear Power Plant Unit-1 was 28 February 2011.

Editorial summary

“OPR-1000” enters the record as south Korean nuclear reactor. Crown Archives preserves that source wording while asking what OPR-1000, South and Korean can confirm, complicate or overturn.

Editorial reviewA concise reference frame for defining the subject, testing terminology and identifying the institution closest to the evidence. The current lead gives the account dated anchors—1000, 2005, 1400, 1995—that can be checked directly. The selected authority fields contribute no independent date. Its strongest next move is a source search built around OPR-1000, South and Korean.
Editorial analysis

Why this record matters

“OPR-1000” is worth following because a concise public description often conceals a longer documentary argument. Here, OPR-1000, South and Korean provides the most credible route into that argument.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 29, 2024. The linked authority identifier is Q11664030. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1000, 2005, 1400 and 1995.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
