Another well-known nuclear-free community is Berkeley, California, whose citizens passed the Nuclear Free Berkeley Act in 1986 which allows the city to levy fines for nuclear weapons-related activity and to boycott companies involved in the United States nuclear infrastructure. The City of Berkeley has posted signs at city limits proclaiming its nuclear free status. The ordinance specifies possible fines for such activities within its borders. The University of California, Berkeley is deeply involved in the history of nuclear weapons, and the University of California system until recently managed operations at Los Alamos National Laboratory, a U.S. nuclear weapons design laboratory, and continues to manage the Lawrence Livermore National Laboratory. At the time of the passage of the act, the University operated a nuclear reactor for research purposes, the Etcheverry Reactor, which it continued to operate after the act went into effect. The University of California, as a state institution, is not subject to Berkeley's municipal regulations, including the ban. Berkeley also has major freeway and train lines which are used in transporting nuclear materials.
