Hi Duane, Based on our discussion earlier, I propose we make the Pu239 sealed source license limit 39 grams. So it reads something to the effect of To receive, possess, and use in connection with operation of the facility, up to a total of 39 grams of Pu239 in the form of sealed plutoniumberyllium neutron sources.
In the event our current 55 year old one curie PuBe source fails a leak test for some reason, this amount allows the UFTR enough flexibility to transfer / borrow a sealed one curie PuBe source from the UF radiation control office to continue operation while maintaining possession of the failed source until we can properly dispose of it. The choice of 39 grams is large enough to accommodate two one curie sources with some tolerance and its a number that should be easy for operators to recall / memorize. (Pu239 as in Pu239 =>
39 grams).

What is the size in grams of the pu-be source? I need it for the license; 1
to receive, possess, and use, but not separate, in connection with operation of the facility, a xx gram, 1 curie sealed plutoniumberyllium neutron source Duane A.
