In reply to Robin's message of Mon, 20 Mar 2023 09:14:28 +1100: Hi, I should add that a 14 MeV D nucleus may well also be capable of fissioning a Th or U nucleus directly, and given that it is a D nucleus rather than a single neutron, it may well also be capable of fissioning lighter atoms

In reply to Robin's message of Mon, 20 Mar 2023 07:10:35 +1100: Hi, PS - another possibility is that a simple elastic collision of a daughter product with a D passes sufficient kinetic energy to the D such that the D itself can split another D, or even multiple D's , thus creating more free

Hi, I may have previously suggested on this list that in Uranium fission reactor where a U salt is dissolved in heavy water, some additional neutrons might be created by the the fission daughter products spalling a neutron from the D in the heavy water. (Jones previously mentioned that CANDU
