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).
In the spring of 1982 activists working for social justice, environmental preservation, and international peace organized a six-week peace vigil at the entrance to the Nevada Test Site, about 60 miles (100 km) from Las Vegas, Nevada. In 1983 they repeated the vigil, calling it the 'Lenten Desert Experience'. This anarchist group of Christian organizers decided that the program had been successful enough to start an organization, which led to a faith-based aspect to the nuclear abolition movement. They named it 'Nevada Desert Experience' or NDE because of the work within the prayer-actions for peace that included learning to appreciate the Mojave and the Great Basin Deserts of North America. Organizers believed that appreciation of the beauty and power of the natural environment, coupled with a universal code of ethics (the Golden Rule) organically leads humans to make a stand for peace and environmental justice.
The movement's immediate goal of ending nuclear testing at the Nevada Test Site was met in 1992, when President George H. W. Bush signed a moratorium on underground nuclear weapons tests. The abolition movement, led by NDE and the Western Shoshone-based Shundahai Network were sparked back into action with the renewal of non-nuclear explosions at the Nevada Test Site in 1997. These "subcritical" bombs use fissile materials which do not reach the self-sustaining chain reaction of a typical nuclear bomb. The bombs are designed by Los Alamos National Laboratory and Lawrence Livermore Laboratory, whereby the data collected can be fed to computers to simulate full-scale nuclear explosions for the US National Security Agency (NSA) and DOE. Their explosive yield is low, and small amounts of radiation may be released. Because each sub-critical experiment costs roughly US$20 million and much time from the humans working within the nuclear weapons management industry, the tests indicate to nuclear abolition activists a strong continued interest (within the U.S. Government) in favor of nuclear weapons. Therefore, the NDE continues to work for deep ecological sensitivities and social peacemaking, with one goal being to clean up and contain the contamination created by 55 years of nuclear testing in Nevada and Western Shoshone country.
