Now accept the deal and prepare all the infrastructure and everything, it is a heavy investment, but in side if we develop technology of thorium based reactors which we have abundant,can't we change the reactors after say some 20 or 30 years back, hope we would develop that technology within that time frame. anyway the protection and infrastructure might be needed same, So i think going for the deal is good, but i am not a expert, so i dont' know whether my perception about changing the reactor only is feasible.
