How much pollution will that rocket cause?
And what happens if the lauch goes wrong? Bang! Oops, a nice radioactive shower for someone's country...!
Do you have any idea how difficult it is to decommission a fission reactor? And are you going to lauch all that material into space too?

Don't use SRB's like the shuttle, just use hydrogen/oxygen rockets.
And you're thinking of using today's technology, when it will be tomorrow's that will be around when the time comes.
As for the cost, what price are you willing to pay to make a drastic change to the green house emissions?
Isn't reducing carbon dioxide and sulphur dioxide pollution worth it? Not to mention all the other nasty carconogenic chemicals which are spewed out from fossil fuel power stations.
Renewable resouces like solar or wind cannot make enough of an impact into our energy and pollution reduction needs, partly through NIMBYs and partly because things like wind turbines produce more pollution in their production than they can save during their lifetime.
