than what ? Storage in massive structures for at least 10,000 years ?
Quote:considering the number of rockets that blow up before they reach space
Seeing you mentioned it, how many rockets is that ? How many are new designs and are not yet known for reliability ?
The Mars launches are of sophisticated equipment which has to function after many months in space, whereas nuclear waste simply has to sit there. Rocket launches have such a high failure rate because Britain, the EU, Japan, China, North Korea, Russia and the USA have all developed their own separate rocket program and have each learnt through their own mistakes to develop their own reliable rockets. Even in the worst case scenario and the reliability of launches can not be improved, it is a relatively simple matter to eject the head of the rocket containing the waste and then detonate the rocket. Making the head crash survivable and easy to recover is again relatively simple but is the part that would draw the most attention from emotional arguments. Hitting the sun is the rocket equivalent of child’s play.
The Saturn V attained 47 tonne to Lunar vacinity, though it could carry about 100 tonne or more for just leaving earth and pointed at the sun, especially as the sun's gravity would help. Because of the high developmental costs Saturn V averaged $2.4-3.5 billion per launch in 2007 dollars. This could be brought down to well under 1 billion per launch or $22,000 per kilogram for leaving high earth orbit. For low earth orbit, NASA charges US$25,000 per kg on the Space Shuttle if you can get the space allocated. The Boeing subsidiary ‘Sea Launch’ charges US$1,000 per kg on old (technology) Russian rockets. Future plans for leaving earth hope to get the cost down to $100-$1,000 per kilogram depending on low earth or leaving high earth orbits.
About 97% of the spent fuel can be recycled leaving only 3% as high-level waste. This means a l,000 MWe nuclear reactor will produce about 700 kg per year.
Major commercial reprocessing plants are operating in France and UK, with capacity of over 5000 tonnes of spent fuel per year, - equivalent to at least one third of the world's annual output. A total of over 55,000 tonnes of spent fuel has been reprocessed at these over 35 years. This means the worlds fuel waste problem could be reduced to 450 tonnes per year. As Saturn V could take a minimum of 100 tonnes per launch, this means 9 launches per 2 years to eradicate new nuclear waste.
The USA alone has collected US$ 18 billion from consumers on a solution. Has it found one ? This would have translated to 4 years with no new nuclear waste in the world. How much will other countries pay to be rid of their high level nuclear waste ?
