Homework Statement


What product of heavy water reactors has been used to create hydrogen bombs?


Homework Equations


This is basically what I'm looking for.


The Attempt at a Solution


It's not a math question. I took an online quiz for my class and it said it was Tritium, but I thought it was Lithium Deuteride. My textbook's terrible index didn't help any, and I couldn't find any online resources. So if you answer this I would be very grateful if you could cite a source :)

Tritium is correct.

Heavy water is predominantly D2O and neutron capture by D produces T (D + n -> T). http://www.fas.org/nuke/intro/nuke/tritium.htm

Thermonuclear weapons have used DT fusion, as well as LiD, but LiD is not a product a heavy water reactor.
