- Perhaps not with your brand of math but in the real world, taking

- Aha! Fresh meat. Love these newbies. Dean, I don't need to "take it to my
- friends in the nuclear industry" because I am part of it. Or was until I
- decided to retire and put ink on dead trees for a living. Neutron
- embrittlement is quite well understood and is being mitigated even as you
- read this. Such things as low enrichment peripheral fuel loading and
- a slight reduction in power does wonders. If or when it becomes necessary
- to address reactor pot enbrittlement, it will be done in one of a couple
- of ways. Either the pot will be annealed in place or a new pot will
- be installed. Either way, the facility continues to operate
- indefinitely. The only reactors that will be decommissioned are those
- that no longer make economoc sense to operate.
