“The use of lead-bismuth as a coolant offers several advantages as a liquid metal coolant for fast reactors. A low melting point, very high boiling temperature, and stability in air are characteristics of lead-bismuth that can contribute to the safety inherent with liquid metal reactors. Consideration of a lead-bismuth must weight the possible drawbacks caused by the presence of Polonium-210, which is produced by neutron activation of the bismuth. This paper describes the results of a test program to evaluate the potential of Polonium to impact the design and safe operation of the reactor.”

For some reason, I now recall the LMFBR guy who came to the parish. Stupidly, I just couldn’t place him at the time. For some reason, just now, ²¹ºPo comes to mind, and the question as to how to irradiate a microgram or even less of ²¹ºPo comes to mind. LMFBR.
Anyway, he showed up again at the same time as the enhanced interrogation / assassination GTMO guys showed up. All of them would know of the one time short-lived interest of Yasser Arafat and Alexander Litvinenko with just the very tiniest bit of ²¹ºPo.
Bill Binney was mentioned in the context of murder as “suicide” by the intel guys. But the purpose of that ever so strange meeting was to discuss the viability, so to speak, of another person altogether. Anyway, the LMFBR guy is checking out a few things for me. He’s in a different line of work than mere LMFBR. Just to say, one of the GTMO guys has everything in the nuclear and medical worlds down cold, as it were, so to speak.
ARISE! LET US BE GOING! 
I admit not understanding any of this. What was it they were asking about Pope Francis? If it was worth it to protect him? Is Bill Binney the theoretical target or…? It’s probably good I do not understand.
A lot of this is baiting. It’s a big Kindergarten.
I suspect that there are not too many blogs in which one can find liquid-metal-fast-breeder nuclear reactors and Naval Station Guantanamo Bay mentioned in the same sentence, not to mention isotopes of polonium…
