The approximate cause of Fukushima was a once-in-a-generation tsunami that exceeded the design constraints that the plant was built under.
Whatever did go wrong at Fukushima wasn't deregulation. That sort of mistake can creep through in even an extremely well regulated environment.
Also, the cost of the cleanup from the Tohoku earthquake that was linked to the tsunami was something like 300 billon; so maybe the fact that they had a design flaw in their nuclear plant maybe doubled the cleanup depending on what the figures on Wikipedia already factor the Fukushima clean up costs in.
Doubling the cost of something is significant, but for an event of that rarity not really a deregulation concern. If you told me that there was a risk of a city being leveled by a tsunami and there was a chance my taxes rising by, say, an unnecessary 10% for 12 months I might (depending on which city) squint at you in confusion about why the 10% was a problem. I've payed 1% disaster levies in my lifetime.
A slight chance of a moderate-in-context one off cost due to a series of unlikely coincidences just doesn't really rate as a major regulatory risk to me. I'd trust the regulators to deal with it for next time as part of their normal process. We have literally had to scour the globe for a decade to find an example where it matters.
