Hypothesis Concerning Irradiation Embrittlement of Uranium (open access)

Hypothesis Concerning Irradiation Embrittlement of Uranium

In discussion with a number of people at HAPO, KAPL and ANL a hypothesis has been evolved which appears to fit available information concerning irradiation embrittlement of uranium as well as indicate a possible solution to the problem.
