Context paragraphs:
Nuclear power debate: The nuclear power debate is a long-running controversy about the risks and benefits of using nuclear reactors to generate electricity for civilian purposes.  The debate about nuclear power peaked during the 1970s and 1980s, as more and more reactors were built and came online, and "reached an intensity unprecedented in the history of technology controversies" in some countries.  Thereafter, the nuclear industry created jobs, focused on safety and public concerns mostly waned.  In the last decade, however, with growing public awareness about climate change and the critical role that carbon dioxide and methane emissions play in causing the heating of the earth's atmosphere, there's been a resurgence in the intensity nuclear power debate once again.  Nuclear power advocates and those who are most concerned about climate change point to nuclear power's reliable, emission-free, high-density energy and a generation of young physicists and engineers working to bring a new generation of nuclear technology into existence to replace fossil fuels.  On the other hand, skeptics can point to two frightening nuclear accidents, the Chernobyl disaster in 1986 and subsequently the Fukushima Daiichi nuclear disaster, combined with escalating acts of global terrorism, to argue against continuing use of the technology.  The debate continues today between those who fear the power of nuclear and those who fear what will happen to the earth if we don't use nuclear power.  At the 1963 ground-breaking for what would become the world's largest nuclear power plant, President John F. Kennedy declared that nuclear power was a "step on the long road to peace," and that by using "science and technology to achieve significant breakthroughs" that we could "conserve the resources" to leave the world in better shape.  Yet he also acknowledged that the Atomic Age was a "dreadful age" and "when we broke the atom apart, we changed the history of the world."

Karachi Nuclear Power Complex: The Karachi Nuclear Power Complex or KNPC is located in Paradise Point, Karachi, Sindh, Pakistan.  It consists of the Karachi Nuclear Power Plant (KANUPP) and the Pakistan Atomic Energy Commission's Control & Instrumentation Analysis Lab (CIAL KARACHI).  Two new nuclear power plants, KANUPP-2 and KANUPP-3, are also under construction at the site.  When complete, the complex of civilian nuclear power plants will produce over 2000 MW of electricity.  The International Atomic Energy Agency safeguards and inspects the complex.  The plant is under construction by the Pakistan Atomic Energy Commission (PAEC) and is financed by the IAEA, the China Guangdong Nuclear Power Group, the China National Nuclear Corporation, and the China Atomic Energy Authority.

WNP-3 and WNP-5: Washington Nuclear Project Nos. 3 and 5, abbreviated as WNP-3 and WNP-5 (collectively known as the Satsop Nuclear Power Plant) were two of the five nuclear power plants on which construction was started by the Washington Public Power Supply System (WPPSS) in order to meet projected electricity demand in the Pacific Northwest.  WNP-1, WNP-2 and WNP-3 were part of the original 1968 plan, with WNP-4 (a twin to WNP-1 and located at the same site) and WNP-5 (a twin to WNP-3, in similar fashion) added in the early 1970s.

Kaliningrad Nuclear Power Plant: The Kaliningrad Nuclear Power Plant (also referred as Baltic Nuclear Power Plant (NPP) or Baltiiskaya NPP, Russian: ) is a nuclear power plant under construction 13 km south-east of Neman, in Kaliningrad Oblast, Russia.  It is seen as a counter-project to the plan to build the Visaginas nuclear power plant in Lithuania and is considered not only as an energy, but also as a geopolitical project.  In June 2013 the construction was temporary stopped for re-designing the project.

Nuclear power in Pakistan: As of 2017, nuclear power in Pakistan is provided by 5 commercial nuclear power plants.  Pakistan is the first Muslim country in the world to construct and operate civil nuclear power plants.  The Pakistan Atomic Energy Commission (PAEC), the scientific and nuclear governmental agency, is solely responsible for operating these power plants.  As of 2012, the electricity generated by commercial nuclear power plants constitutes roughly ~3.6% of electricity generated in Pakistan, compared to ~62% from fossil fuel, ~33% from hydroelectric power and ~0.3% from coal electricity.  Pakistan is not a party to the Nuclear Non-Proliferation Treaty but is a member of the International Atomic Energy Agency.  Pakistan plans on constructing 32 nuclear power plants by 2050.

Kuosheng Nuclear Power Plant: The Kuosheng Nuclear Power Plant or Guosheng Nuclear Power Plant (國聖核能發電廠), Second Nuclear Power Plant (第二核能發電廠 or 核二), is a nuclear power plant in Wanli, New Taipei, Taiwan.  The plant is currently the largest nuclear power plant in Taiwan, before the opening of the 2,700 MW Longmen Nuclear Power Plant which is still under construction.

Cherokee Nuclear Power Plant: The Cherokee Nuclear Power Plant is an uncompleted energy project 10 mi outside of Gaffney, South Carolina, United States.  In the early 1970s, Duke Power started construction on a three-reactor nuclear power plant at the site.  However, the project stalled due to economic problems by the early 1980s, leading to the project's eventual abandonment.  In 1987, the power plant was the site of an underwater film studio built by Hollywood director James Cameron, for the film "The Abyss".

WNP-1 and WNP-4: Washington Nuclear Project Nos. 1 and 4, abbreviated as WNP-1 and WNP-4 were two of the five nuclear power plants on which construction was started by the Washington Public Power Supply System (WPPSS) in order to meet projected electricity demand in the Pacific Northwest.  WNP-1, WNP-2 and WNP-3 were part of the original 1968 plan, with WNP-4 (a twin to WNP-1 and located at the same site) and WNP-5 (a twin to WNP-3, in similar fashion) added in the early 1970s.

Nuclear energy in Austria: In the 1960s the Austrian government started a nuclear energy program and parliament unanimously ordered a nuclear power plant built.  In 1972, the German company KWU began construction of the Zwentendorf Nuclear Power Plant boiling water 700 MWe reactor.  In 1976, two years prior to the nuclear power plant opening, the government began a program to educate its citizens on the benefits and safety of nuclear power.  However, this campaign began a public discussion that led to large demonstrations against the Zwentendorf plant in 1977.  On 15 December 1978, the Austrian Parliament voted in favor of a ban (BGBI.  No. 676) on using nuclear fission for Austria’s energy supply until March 1998.  This law also prohibits the storage and transport of nuclear materials in or through Austria.  On 9 July 1997, the Austrian Parliament unanimously passed legislation to remain an anti-nuclear country.

Energy Northwest: Energy Northwest (formerly Washington Public Power Supply System) is a United States public power joint operating agency formed by State law in 1957 to produce at-cost power for Northwest utilities.  Headquartered in Richland, Washington, the WPPSS became commonly known as "Whoops" due to over-commitment to nuclear power in the 1970s which brought about financial collapse and the second largest municipal bond default in U.S. history.  WPPSS was renamed Energy Northwest in November 1998.  Agency membership includes 28 public power utilities, including 23 of the state’s 24 public utility districts.
