Is the last sentence grammatically correct and does it make sense? If you rewrite the sentence into "Even if such a serious accident were never to happen again, we have to manage...", then does it make sense and is it grammatically correct?

According to the report of an investigative committee on Tepco’s finances and management, damages owed as a result of the accident are estimated to reach 4.5 trillion yen by March 2013. It is not known how far these costs will finally balloon. This is equivalent to the final destruction of the idea of low-cost nuclear power. Even supposing that such a serious accident were never to happen again, we have to manage the nuclear waste for hundreds of thousands of years, no matter the waste disposal method, and that cost is unimaginable.

I think your sentence means about the same as the original sentence, and they are both correct.
