Question: What is Area 2 a division of that includes Nuclear weapons testing?

Context paragraphs:
Timeline of nuclear weapons development: This timeline of nuclear weapons development is a chronological catalog of the evolution of nuclear weapons rooting from the development of the science surrounding nuclear fission and nuclear fusion.  In addition to the scientific advancements, this timeline also includes several political events relating to the development of nuclear weapons.  The availability of intelligence on recent advancements in nuclear weapons of several major countries (such as United States and the Soviet Union) is limited because of the classification of technical knowledge of nuclear weapons development.

Louise Reiss: Louise Marie Zibold Reiss (February 23, 1920 – January 1, 2011) was an American physician who coordinated what became known as the Baby Tooth Survey, in which deciduous teeth from children living in the St. Louis, Missouri area who were born in the 1950s and 1960s were collected and analyzed over a period of 12 years.  The results of the survey showed that children born after 1963 had levels of strontium-90 in their teeth that were 50 times higher than those found in children born before the advent of widespread nuclear weapons testing.  The findings helped convince U.S. President John F. Kennedy to sign the Partial Nuclear Test Ban Treaty with the United Kingdom and Soviet Union, which ended the above-ground testing of nuclear weapons that placed the greatest amounts of nuclear fallout into the atmosphere.

Paul Langley: Paul Langley is a South Australian historical researcher and the author of non-fiction books on nuclear weapons testing in Australia, the history of nuclear industrial development and the Fukushima nuclear disaster.  His works include: "The truth surrounding atomic fiction : cold war propaganda & modern views on radiological safety in Australia" (1996), "The Maralinga Files" (2001-2003), "Maralinga chronology : the atomic tests in Australia and their radiological impact" (2003),"The prediction of the radiological effects of atomic bombs from knowledge published prior to 1945" (2009), "The consequences of the use of atomic weapons as informed by the findings of nuclear medicine prior to 1943" (2009) and "Medicine and the Bomb : deceptions from Trinity to Maralinga" (2009).  He contributed to the compilation "Fukushima: Disposession or denuclearization?"  and maintains a blog where he writes about the history of nuclear industrial development.

India and weapons of mass destruction: India possesses weapons of mass destruction in the form of nuclear weapons and, in the past, chemical weapons. Though India has not made any official statements about the size of its nuclear arsenal, recent estimates suggest that India has 110 nuclear weapons consistent with earlier estimates that it had produced enough weapons-grade plutonium for up to 75–110 nuclear weapons.  In 1999 India was estimated to have 800 kg of separated reactor-grade plutonium, with a total amount of 8300 kg of civilian plutonium, enough for approximately 1,000 nuclear weapons.  India is not a signatory to the 1968 Nuclear Non-Proliferation Treaty (NPT), which it argues entrenches the status quo of the existing nuclear weapons states whilst preventing general nuclear disarmament.

Nevada Desert Experience: The Nevada Desert Experience is a name for the movement to stop U.S. nuclear weapons testing that came into use in the middle 1980s.  It is also the name of an anti-nuclear organization which continues to create public events to question the morality and intelligence of the U.S. nuclear weapons program, with a main focus on the United States Department of Energy's (DOE) Nevada Test Site (now renamed the Nevada National Security Site).

Nuclear weapons testing: Nuclear weapons tests are experiments carried out to determine the effectiveness, yield, and explosive capability of nuclear weapons. Throughout the twentieth century, most nations that developed nuclear weapons tested them.  Testing nuclear weapons can yield information about how the weapons work, as well as how the weapons behave under various conditions and how personnel, structures, and equipment behave when subjected to nuclear explosions.  Nuclear testing has often been used as an indicator of scientific and military strength, and many tests have been overtly political in their intention; most nuclear weapons states publicly declared their nuclear status by means of a nuclear test.

Treaty on the Prohibition of Nuclear Weapons: The Treaty on the Prohibition of Nuclear Weapons, or the Nuclear Weapon Ban Treaty, is the first legally binding international agreement to comprehensively prohibit nuclear weapons, with the goal of leading towards their total elimination.  It was passed on 7 July 2017.  In order to come into effect, signature and ratification by at least 50 countries is required.  For those nations that are party to it, the treaty prohibits the development, testing, production, stockpiling, stationing, transfer, use and threat of use of nuclear weapons, as well as assistance and encouragement to the prohibited activities.  For nuclear armed states joining the treaty, it provides for a time-bound framework for negotiations leading to the verified and irreversible elimination of its nuclear weapons programme.

Area 2 (Nevada National Security Site): Area 2 is a division of the Nevada Test Site in the Mojave Desert.  The area is located 18 miles south-east of Area 51.

Nevada Test Site: The Nevada National Security Site (N2S2),(though the abbreviation NNSS is still used), previously the Nevada Test Site (NTS), is a United States Department of Energy reservation located in southeastern Nye County, Nevada, about 65 miles (105 km) northwest of the city of Las Vegas.  Formerly known as the Nevada Proving Grounds, the site was established on 11 January 1951 for the testing of nuclear devices, covering approximately 1,360 square miles (3,500 km) of desert and mountainous terrain.  Nuclear weapons testing at the Nevada Test Site began with a 1-kiloton-of-TNT (4.2 TJ) bomb dropped on Frenchman Flat on 27 January 1951.  Many of the iconic images of the nuclear era come from the NTS.  NNSS is operated by National Security Technologies, LLC, a joint venture of Northrop Grumman, AECOM, CH2M Hill, and Babcock & Wilcox.

Two Futures Project: The Two Futures Project (2FP) is a movement made up of American Christians who support and work towards the abolition of all nuclear weapons.  This organization believes that human beings face two futures and one choice: a world without nuclear weapons or a world ruined by them.  2FP is supportive of concrete and practical steps to reduce nuclear dangers immediately, while pursuing the multilateral, global, irreversible, and verifiable elimination of nuclear weapons, as a biblically-grounded mandate and as a contemporary security imperative.  In order to make these changes in the world they are using a strategy based around the creation of a non-partisan, conscience-driven, enduring majority of Americans who are committed to a nuclear weapons-free world.  Two Futures Project seeks to join together one voice of Christian conscience, to encourage and enable national leaders to make the complete elimination of nuclear weapons the organizing principle of American nuclear weapons policy.  The founder and director of the Two Futures Project is Rev. Tyler Wigg-Stevenson.
