I can't imagine a more knowledgeable interviewer on this topic than Rod Adams - publisher of Atomic Insights and enthusiastic advocate of small nuclear generators. I knew he was reading my book and was anxiously awaiting his opinion of it. He interviewed me for his podcast The Atomic Show, give it a listen.
As one indication of the depth of Rod's knowledge, he corrects me in the interview when I state that the Army's ML-1 reactor never went critical. As Rod correctly points out, it was critical for about 300 hours.
