2min 22sec #movietone clip - Maralinga Nuclear Test - 1957 | Movietone Moments 5th October
Text from youtube "Last week in 1957 Great Britain performed a nuclear test at Maralinga in Australia. Here’s a remarkable report from Movietone about this event.
Maralinga Test Range in the stark-wide open spaces of South Australia. "Operation Buffalo" involved setting up a village for servicemen taking part. And the team of scientists was headed by Sir William Penney who went to supervise and observe the atomic explosions.
Experimental explosion of an A-Bomb. Scientists alight from plane including Sir William Penney. Signposts - 'London Road', 'Maralinga Village'. Native postman. Native has hair cut. Native cooking. Servicemen in canteen. Guns firing. Tanks. Bulldozer. Mock fighting. Army photographer. Vulcan bomber takes off. Various shots of guns and tanks to be used for testing atomic rays. A-Bomb explodes. Good mushroom shots. Jet plane takes off. Scientist in protective clothing walk round the contaminated area. Various shots of the damage done to army vehicles and clothing from the A-Bomb."

4min 18sec clip - simulation for a plausible escalating war between the United States and Russia using realistic nuclear force postures, targets and fatality estimates
found via a digg email
text from youtube "Our team developed a simulation for a plausible escalating war between the United States and Russia using realistic nuclear force postures, targets and fatality estimates. It is estimated that there would be more than 90 million people dead and injured within the first few hours of the conflict.

Text from you tube
"On August 24, 1968, France became the world's fifth thermonuclear power as it exploded a hydrogen bomb in the South Pacific. The island of Fangataufa site for the Test of France's first H-Bomb. An explosion equal to three millions tons of TNT makes France the 5th H-Bomb power in the World."

Text from youtube "High Resolution, complete scans of Atomic Bomb FCDA Footage from shot Grable (1953). Grable was an atomic artillery shell, shot out of a cannon and detonated on Frenchman Flat at the Nevada Test Site. No sound. Filmed at 64 frames per second (normal speed is 24 fps).
Yield was 15 KT.
Distance to Ground Zero: 2,938 feet.
Camera elevations ranged from 11 ft 3 inches above ground to 18 ft 9 inches high."

1min 11sec Lawrence Livermore National Laboratory clip - #USA atmospheric #nuclear test
found via a digg email
Text from youtube "The U.S. conducted 210 atmospheric nuclear tests between 1945 and 1962, with multiple cameras capturing each event at around 2,400 frames per second. But in the decades since, around 10,000 of these films sat idle, scattered across the country in high-security vaults. Not only were they gathering dust, the film material itself was slowly decomposing, bringing the data they contained to the brink of being lost forever. For the past five years, Lawrence Livermore National Laboratory (LLNL) weapon physicist Greg Spriggs and a crack team of film experts, archivists and software developers have been on a mission to hunt down, scan, reanalyze and declassify these decomposing films. The goals are to preserve the films’ content before it’s lost forever, and provide better data to the post-testing-era scientists who use computer codes to help certify that the aging U.S. nuclear deterrent remains safe, secure and effective.

8min 6sec #TEDEd clip - What are the challenges of #nuclear #power? - M. V. Ramana and Sajan Saini
Our ability to mine great amounts of energy from uranium nuclei has led some to bill nuclear power as a plentiful, utopian source of electricity.
But rather than dominate the global electricity market, nuclear power has declined from a high of 18% in 1996 to 11% today.
What happened to the great promise of this technology?
M.V. Ramana and Sajan Saini detail the challenges of nuclear power, animation by Wooden Plane Productions.

the uk & chernobyl - the situation in 1997 - so whats it like now? - 5 things re the 1997 stats to think about
the source of the summary below is the ever excellent uk parliament notes
1) 7 years later (1997), areas of the UK remained contaminated with radioactive fall-out from Chernobyl, to the extent that the movement and slaughter of almost 1/2 million sheep on more than 600 farms were still subject to restrictions.
2) the average Chernobyl fallout dose per person in Cumbria was 6 times the UK average.
3) Radioactive caesium can remain unbound if it is readily taken up by plants and thence into animals. Caesium can then become continuously recycled; i.e. excreted by animals, re-incorporated into plants, re-ingested by animals and so on. The following soil factors all tend to increase caesium uptake into plants (and thus animals): Low clay content; High acidity; Low mineral (especially potassium) content; high organic content - this retains 'free' caesium near the surface (where it is taken up by roots) ; Waterlogging - increases the ‘pool’ of mobile caesium
4) Earlier experience with caesium fallout from nuclear weapons testing in the 1950s and '60s suggests that upland soils may take as long as 30 years to immobilise most of the caesium
5) Since Chernobyl it has become increasingly apparent that many of the 60 or so nuclear reactors of Soviet design still operating in Eastern and Central Europe do not conform to Western standards. The main safety concerns relate to inadequate containment and emergency core cooling systems, although there are also doubts about standards of construction and operating methods (which may lead to premature ageing of the reactor).
