No, I'm sorry but you can only increase safety as far as overall plant design will allow. My logic was not faulty, I did not say that replacing a failing part did not increase safety. I said it does not improve the safety of the design of the plant.
I don't hate nuclear power, I feel it is a necessary component of any national energy supply that does not contribute as much damage to the environment as coal or natural gas (when the radioactive remains are properly dealt with).
Thanks for your input.
