Ron,
thanks
one benifit of a nuc plant is that power availability is great enough that a lower pressure and temp can be run to get the same or greater steam flow than a fossil plant. ie. 600# and 500 degree F. This in itself leads to lesser potential hazards from the beast itself! Oh, those numbers are for the secondary or steam side of the plant the reactor numbers for temp and pressure are different and I'll leave those alone. Its fun to discuss, but even though any "good" engineer should be able to figure it out, some info should and will stay under the table.
Have a great thanksgiving!!
