Simulation of Nuclear Weapon Secondary Explosion

Anonymous Coward writes "Here is what all those DOE supercomputers have been crunching: On April 30, the Crestone project team at the Laboratory successfully completed the first three-dimensional simulation of a nuclear weapon secondary explosion. The total processor time was 2.01 million hours... The details are at Los Alamos National Laboratory." The secondary explosion in today's modern weapons occurs when a fission device explodes and compresses a light isotope (often tritium) until it creates a fusion reaction. This increases the total yield by a factor of perhaps 100-1000.
