    WASHINGTON: The United States said Thursday it has conducted a "subcritical" nuclear test at an underground site to study the behavior of nuclear materials without triggering an atomic explosion.

    The test, conducted Wednesday in Nevada, aims to gather scientific data that will "provide crucial information to maintain the safety and effectiveness of the nation's nuclear weapons," the Energy Department said in a statement.

    "Challenging subcritical experiments maintain our capabilities to ensure that we can support a safe, secure and effective stockpile without having to conduct underground testing," said National Nuclear Security Administration head Thomas D'Agostino.

    Staff from the Nevada National Security Site, Los Alamos National Laboratory and Sandia National Laboratories conducted the experiment, known as Pollux. It marked the 27th subcritical experiment to date. The last one, known as Barolo B, took place in February 2011.

    Subcritical nuclear tests, which do not trigger a self-sustaining chain reaction that would create a nuclear explosion, examine how plutonium behaves when it is shocked by forces produced by chemical high explosives.

    The United States halted underground nuclear tests in 1992. By then, it had conducted 1,032 tests since 1945, according to UN figures.

    I thought CTBT meant comprehensive test ban treaty and comprehensive means complete.

    The treaty bans nuclear explosion.

    The test was sub-critical, that is, no nuclear explosion involved. Infact, this was the exact purpose of the test. To ensure safety, part of which is that no explosion occurs by accident and reliability, that explosion does occur when intended.

    In layman's term, they didn't tested a nuke.

    There is no test of atomic detonation, which is a core part of a nuclear weapons test.
