Here's a photograph of Dr. Weinberg, who worked with an knew scores of Nobel Laureates, with Nobel Laureate Cliff Shull, who performed his Nobel Prize winning work under Dr. Weinberg's directorship.

As it happens, I have Dr. Weinberg's book in front of me right now. I cite from his text on Glenn Seaborg's participation in the Molten Salt Reactor Operations:
The Molten Salt reactor began operation in 1966 and achieved its maximum power (limited by the size of the air cooled ultimate heat exchanger of of 7,500 kilowatts in March of that year. It continued to operate remarkably smoothly, though with interruptions for maintenance, until December of 1969, when its operation was terminated so that funds could be diverted to the development of more advanced molten-salt systems. We were delighted with the MSRE. Here we had a high-temperature fluid fuel reactor that operated reliably and, even the primitive embodiment represented by MSRE, had remarkably low fuel costs. Before shutting down the MSRE, we operated with 233U as fuel. Glenn Seaborg and Ray Stoughton, co-discoverers of 233U were in the control room we we began a yearlong run with 233U. This was the first time any reactor operated with 233U as fuel. I think Glenn who was chair of the AEC, must have been pleased to see "his" 233U being put to practical use!
Ibid, Weinberg, page 126-127. The transcription and the bold are mine.
I was in Glenn Seaborg's presence exactly once in my life. I would not presume, of course, to put any words in the mouth of that august scientist, for whom I felt such awe and from whom young people today may take scientific inspiration. However I will say that in person - at the ACS meeting where he was being honored with the naming of Seaborgium - he seemed very much the gracious man who comes across in print. I very much doubt that he would be nearly as vicious as I am in addressing the obvious ignorance of anti-science anti-nuke stumble bumb types. I don't think he messed much with houseflies.
But the fact is that dumb people, again from a position of total ignorance, are trying to destroy his life's work. My personal position, irrespective of Dr. Seaborg's (or Dr. Weinberg's) is that it is the duty of educated people to
confront ignorance and
fight it.
It is my oft stated conviction that better than 99% of anti-nukes are the intellectual equivalents of creationists, since like creationists, they hate, from a dogmatic and completely uneducated position, a science about which they clearly know nothing.
They have no respect for nuclear science (or, in fact
any science) because it's pretty clear that they have never opened a science book in their pathetic lives.
Often when I state this
fact about the intellectual standing of anti-nukes, they show up to verify my contention, although usually while being completely oblivious to their dogmatism and lack of wit.
I am always thankful for that, and of course, appreciate it presently.
In general, like creationists, anti-nukes are too stupid to grasp precisely how clownish they are. The fact is that without smiley buttons, they would be spectacularly unable to express themselves, which is, of course, a reflection of the hollows of their minds.
Have a nice evening.
