For many years the anti-nuclear movement in the United States succeeded in delaying or halting commitments to build some new nuclear plants. Anti-nuclear campaigns that captured national public attention in the 1970s involved the Calvert Cliffs Nuclear Power Plant, Seabrook Station Nuclear Power Plant, Diablo Canyon Power Plant, Shoreham Nuclear Power Plant, and the Three Mile Island accident. More recent targeted campaigning has related to the Indian Point Energy Center, Oyster Creek Nuclear Generating Station, Pilgrim Nuclear Generating Station, Salem Nuclear Power Plant, Vermont Yankee Nuclear Power Plant, Idaho National Laboratory, proposed Yucca Mountain waste repository, the Hanford Site, the Nevada Test Site, Lawrence Livermore National Laboratory, and transportation of nuclear waste from the Los Alamos National Laboratory. Many different groups have been involved in various protests and demonstrations over the years.
