  Nuclear Issues - Nuclear Testing
While stopping short of overturning his father's moratorium on nuclear testing, U.S. President George W. Bush has catapulted the testing issue back into the political foreground with the Pentagon's new Nuclear Posture Review (NPR).
Following the NPR's release, White House spokesman Ari Fleischer was at pains to point out that Bush "has not ruled out testing in the future."

  BBC NEWS | Asia-Pacific | Factfile: Underground nuclear testing
Nuclear devices are often tested underground to prevent radioactive material released in the explosion reaching the surface and contaminating the environment, and to ensure a degree of secrecy.
The release of radiation from an underground nuclear explosion - an effect known as "venting" - would give away clues to the technical composition and size of a country's device, and therefore its nuclear capability.
North Korea is believed to have conducted a test of a relatively small device at a site called P'unggye-yok in a remote area in the east of the country, near Gilju.

  Nuclear Weapon Testing
The term “nuclear testing” encompasses all experiments in which special nuclear material (or a simulant) is placed in contact with high explosives, which are then detonated, or with a propellant, which is ignited.
Nuclear weapons effects tests are primarily carried out in horizontal mine shafts sealed to prevent the escape of debris; instrumentation cables are connected to the surface through a vertical bore hole.
In both cases, the tests are characterized by the large amount of electronic instrumentation used to study the details of the functioning of the implosion assembly and of the nuclear phases of the explosion.

Additionally, nuclear testing has often been used as an indicator of scientific and military strength and many tests have been overtly political in their intention, and most nuclear weapons states publicly declared their nuclear status by means of a nuclear test.
Nuclear explosions which are close enough to the ground to draw dirt and debris into their mushroom cloud can generate large amounts of nuclear fallout due to irradiation of the debris.
Nuclear testing has since become a controversial issue in the United States, with a number of politicians saying that future testing might be necessary to maintain the aging warheads from the Cold War.

A nuclear test explosion is an experiment involving the detonation of a nuclear weapon.
Nuclear weapons tests are generally classified as being either "atmospheric" (in or above the atmosphere), "underground," or "underwater." Of these, underground testing contained in deep shafts poses the least health risk in terms of fallout.
Planned as a method to dispel doubts about whether the USA's nuclear missiles would actually function in practice, it had less effect than was hoped, as the stockpile warhead was substantially modified prior to testing, and the missile tested was a relatively low-flying SLBM and not a high-flying ICBM.

 Underground Nuclear Weapons Testing ? United States Nuclear Forces
Tests in vertical drill holes are of two types: smaller-yield devices in relatively shallow holes in the Yucca Flat area (Areas 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10) and higher-yield devices in deeper holes on Pahute Mesa (Areas 18, 19, and 20).
When a hole is selected as a location for a nuclear test, the area around the hole is surveyed and staked according to the criteria set forth by the sponsoring national laboratory.
The nuclear explosive and special measurement devices are moved to the hole and lowered to the detonation position; all required diagnostic materials and instrumentation cables are also lowered into the hole at this time.

 Smaller Bangs, But Still Testing the Bomb
Then, as now, the nuclear weapons establishment insisted on a wide range of "safeguards" to assure the continued ability to develop nuclear weapons after full-scale testing was restricted, including extensive research facilities at the nuclear weapons laboratories and a continuing program of underground nuclear tests, hundreds of which were conducted in subsequent years.
The Limited Test Ban Treaty did little to restrict the ability of the United States and the U.S.S.R. to refine their nuclear arsenals, with smaller, lighter warhead designs tested underground leading to the hair-trigger arsenals of the present, replete with multiple warhead, highly accurate missiles deployed on an assortment of sophisticated delivery systems.
Although these are tests only of materials and components rather than full nuclear warheads, the Stockpile Stewardship program of which they are a part is intended to provide increasingly advanced capabilities to integrate data from a variety of testing techniques into simulations of nuclear weapons performance.
