2. Safety issues cannot be resolved technologically. False.  The phrase "walk-away safe" indicates that one can have a reactor running normally and walk-away from it without any bad consequences - apart from the loss of electricity.  The current designs are not walk-away safe but the latest version of light water reactors (Koeberg is an early example of this kind) - the ones being built at the moment - approach that status.  Change the design of the reactor to such as an MSR, a Molten Salt Reactor, and there is no doubt of walk-away safety.  So "cannot be resolved technologically" is a statement which can only be made (with such confidence!) by a non-expert.
