Can’t figure it would be tougher to explain than Effective Full Power Hours.Really?
Kinda figured that would bore the S*** out of everyone.

Not a matter of "tougher to explain" so much as, does anyone really care?Can’t figure it would be tougher to explain than Effective Full Power Hours.
One little point - in the reactor, fission is going on all the time. The poisons control the fission rate. The fission you don't want is uncontrolled fission - it gets too hot to contain and you have a melt down and if there is critical mass you have a nuclear bomb.Not a matter of "tougher to explain" so much as, does anyone really care?
okay.
first, what is a "poison"?
A poison is an atom that will absorb a neutron. It will not slow down the neutron (so it can not cause a fission in the future). It will not fission.
Now, there are several types of poisons, one of which is a "burnable poison".
A Reactor has an excess amount of reactivity. You don't want to start fission, and then it's all burned out in a second. So poison is used so that you can load extra reactivity.
Some of these are burnable poisons, loaded throughout the fuel cells.
As opposed to the poisons in the control rods, which are concentrated in the rod, the burnable poisons are loaded throughout the fuel.
yes. And I forgot to mention, as the reactor fissions, causing there to be less reactivity over time, the poisons (burnable) become less also.One little point - in the reactor, fission is going on all the time.

President Biden to nominate Joe Donnelly as ambassador to the Vatican - Indianapolis Business Journal
Donnelly, a devout Catholic, defended Biden’s Catholic faith during last year’s presidential campaign, writing in an op-ed published in August 2020 that Biden “lives his faith every day.”www.ibj.com
Out of curiosity, is there anything to prevent the senators from hiring private security people to deal with the bathroom busters and boat chasers?
