Right, and ultimately Japan has decided the safest and I assume cheapest route with these reactors wasn't to rebuild but rather to decommission.
These reactors can be made safer, but they all still have a foundational design flaw which means the ultimate goal should be replacing rather than continually spending money reinforcing.
