Following the Question on the disposal of nuclear waste (NCE last week), surely there is also the environmental cost to consider as some high level waste takes 20,000 years to become safe.
While I agree that low level waste could be stored, the proposal to dump it at the bottom of the ocean, which we have not fully explored, might have unforeseen side effects on the ecosystem.
Storage on land is always a thorny issue with the 'not in my back yard' reaction of the public, even when their general response to nuclear power is favourable, so I would limit this to the low level waste only.
The high level waste, while the biggest risk, is the easiest to solve. We should place it in a rocket, and direct it into the sun, the largest nuclear reactor in the solar system. We might offset the sun's expansion to a red giant in a few billion years by a couple of milliseconds, but there is no residual affect on the environment.
