A second test in May 2009 is believed to have been about two kilotons
, National Intelligence Director James Clapper told a Senate committee in 2012.
The company plans to increase name-plate capacity at its polyols plant in Terneuzen, The Netherlands by 180 kilotons
per year, and at its propylene glycol facility in Stade, Germany by 80 kilotons
Similar techniques could detect argon-37 from a nuclear bomb, even though a mere 15 cubic centimeters of the gas- "the volume of a Ping-Pong ball"- would be produced per kiloton
of explosive yield, he explains.
The capacity of Henan Xindaxin Materials has been on the rise in recent years, and the cutting material capacity will hit 100 kilotons
or so at the end of 2011.
Recognizing the limitations on the numbers and locations of sensors, international negotiators have opted for a system that-in theory-can detect unmuffled explosions with yields down to roughly a kiloton
, says Bratt.
has the annual capacity of 278-kiloton
viscose fiber, hereinto, the capacity of viscose staple fiber takes 270 kilotons
per annum; its differentiated fibers include Anti-fcell and Newdal fiber.
The source, who is said to have direct knowledge of the message and is close contact with both Beijing and Pyongyang's top officials, said that North Korea's future nuclear tests would be much larger, with a device yielding 10 kilotons
, compared to the most recent test which was 6-7 kilotons
is equivalent to 1,000 tons of TNT.
Although the researchers say they have more confidence in their sheltering recommendation than in their estimates of lives that would be lost, they argue there would be almost 80,000 fatalities in the immediate aftermath of detonation of a 10 kiloton
improvised nuclear device on the Washington Mall.
seismologists should be able to reliably detect tests as small as 1 kiloton
, which would enable verification down to that level, says Adrian DeWind of NRD.
Along with the breakthroughs in carbon fiber industrialized technologies, the successively released policies for carbon fiber industry development, and the stimulation of the huge gap between supply and demand in domestic market, China has launched a lot of research projects concerning carbon fiber and kiloton
According to Hannon, an unmuffled 1 kiloton
(KT) explosion, for example, might produce body waves-- seismic waves that travel down through the earth's mantle and crust--with magnitudes between 3.
With the present state of technology, most experts agree that seismic networks can easily detect events well below the 150 kiloton
(KT) limit of the Threshold Test Ban Treaty (TTBT).
Web searches for North Korea and Kim Jong Il have exploded since the testing a one kiloton
nuclear device and the subsequent sanctions imposed by the United Nations Security Council.
Perhaps this phasing out of larger weapons would be beneficial to the world if all states possessing nuclear weapons of over 20 kilotons
volunteered to destroy them.
Most of them are chargers with a power of 10 to 20 kilotons
