Not neccesarily, you've got to start somewhere. This may or may not be the right place to start. Though it sounds like it could be a step in the right direction. Evan as it may not be able to power large cities, it may be viable as an alternative for more remote locations that don't need or warrant large reactors. Again, it'll be interesting to see how it pans out after implementation and if they can improve upon it.

Well, very true - small scale definitely. The 4S design is currently being implemented in Galena, Alaska where 10MW is more than sufficient for a small village-type community. It is also the testing platform for future 4S expansion projects elsewhere. In my professional opinion, it is still premature to say whether or not the technology is safe and/or reliable, because it is not yet fully tested. If you ask anyone else in the nuclear power industry they will agree.
A lot has to happen in order for the NRC to give this design the proverbial two thumbs up, and it's not a quick process. It will involve extensive pre-license application reviews, formal and informal meetings between Toshiba officials and NRC staff, the actual application process - and then the real fun begins. I am sure that the design is solid and will prove to be worthy of NRC's approval, but until that time arrives, as a power professional myself, it is simply a matter of speculation as to its worth and real-world value once they begin coming online. I
do not see a 10 MW reactor revolutionizing the way we generate power at this time - even back when I was operating reactors for the US Navy, the reactors we used on the ships were more than 15 times the thermal output capacity of the proposed 4S.
Not disagreeing with you Jack H., just stating my professional opinion that it is wise to not get too far ahead of yourself on this one. People have become far too desperate for the "Magic Bullet" that will solve our energy crisis once and for all, but you have to remain focused on the bigger picture overall. By the way, many newly proposed designs sits in the hands of the NRC at this moment, not just the 4S. It just happens that the topic found its way to AH this time, because Toshiba is behind it.
