Whoa... life comes full circle.
I came to Chicago fresh out of graduate school as a Nuclear Engineer for Commonwealth Edison in the late 80's. As a single guy living in Lincoln Park in the early 90's, and out of shear boredom, I opened an account at TransMarket Group, leased one of Ray's evening Full Memberships, and started trading during the evening Pit sessions. During the daytime I would manage these really big technical projects, and at about 6:00 pm every evening I would walk over the the Board and start trading. My badge was "NUK".
Well, the Chairman of ComEd was elected to the CBOT Board of Directors (the Irish Mafia - they are all Irish, Italian, or Jewish in the Exchange Hierarchy), and of course everybody on the sitting Board knew about me - I was a novelty at that point. Well, a few weeks into the Board gig the ComEd CEO called me up and told me that I was no longer a Nuclear Engineer, and that I was now assigned to help start up a new energy trading desk and from then on I was a full-time trader.
I have eight international patents in Radiation Shielding and the use of robotics and remote handling.
A few comments born of sincere knowledge on the topic:
1. We were always amazed that the Japanese built those sites on that level of seismic activity. Everything in the U.S. is seismically qualified in terms of site location and construction specs. If we wanted to institute a mod on a safety-related system, we would build it, load it on a skid, and then truck the damn thing down to Huntsville Alabama and G-Load test it on the Martin-Marietta Space Station G-Load Shake Table. In other words, everything we did on a Safety-Related System had to be seismically qualified at a factor of "X to the Y" beyond a known 'worse case scenario'.
2. I don't understand the whole off-set power diesel generator problem. I thought the Japs were smarter than we are. Every Emergency-Planning Scenario we practiced (several times per year) involved the loss of off-site power to a tornado or such. Part of our mandatory checklist for operations was to routinely start up and run the diesel generators. I mean these things are like 5 or 6 locomotive engines - literally. And we always had huge storage tanks of diesel fuel that were checked every week for purity and stratification. By law, if we couldn't start up our diesel generators within like 5 minutes of initiation during a mandatory monthly test overseen by the Nuclear Regulatory Commission, we had to shut down the plant competely in 12 hours.
3. There are like 12 different defense-in-depth systems to cool down a reactor core in the US. Worse case scenario is we have a gravity-fed tank of boron solution that completely immobilizes the reactor core - and that's just a manual gate-valve.
4. There are reactor vessel and reactor building primary containment systems in duplicate that Chernobyl never had. The "1000 times" radiation releases you are hearing about are very short-lived isotopes that are essentially high energy noble gases where the photon energy components are at background levels by the time they reach the plant boundary. In other words, radiation detectors at the off-gas stack read Z and the radiation detectors at the plant boundary fence read background. The really damaging isotopes like Cs-137 and Co-60 are scrubbed through large charcoal beds; there is no avenue for them to escape into the atmosphere without scrubbing. Here in the US we have to pressure-test our containment structures routinely in the presense of the Nuclear Regulatory Commission.
