How else can nuclear bombs be tested?
The CTBT bars future nuclear tests, but Britain and the US are among nuclear powers that have turned to computer simulations to study nuclear explosions. A £100m laser facility called Orion is being built at Aldermaston to reproduce for a fraction of a second the conditions inside a thermonuclear explosion. Can North Korea launch a nuclear missile? Many experts suspect North Korea has yet to build a nuclear bomb that is small and light enough to launch on a long-range missile. The country has developed Taepodong-1 missiles with a range of 2,000km, and is now working on the longer-range Taepodong-2 missiles, which will have an expected reach of 5,000-6,000km.
