I do, but there also is a lot of pressure to close nuclear reactors because the perceived danger of nuclear power is a lot higher than its real danger.

Also, would you be in favor of _not_ changing the model for current reactors if updated models predict a shorter life time? If you think the model should be updated in those cases, that introduces bias. It also could mean reactor owners would stop making measurements, and that, in turn, would mean we would learn less about making safer reactors.
