Hello. Everyone in this video are being asked why uranium fuel rods and nuclear reactors cannot be used in atomic weapons without further processing. So, we're gonna go ahead and read through all of these four different statements and seeing if this answers the question starting off with option A. This reads that the uranium fuel rods and nuclear reactors are too hazardous for use and atomic weapons. So option A is not the best answer to the question because whether or not uranium fuel rods we used in nuclear reactors are further processed for using nuclear weapons, they're still extremely hazardous. So the fission products of you to 35 are radioactive and some so CCM 1 37 extra medium 90 are very dangerous when relating to the environment. So option A here is going to be eliminated. Moving on to option B. This reads the uranium fuel rods and nuclear reactors are too massive and almost impossible to transport during military views. So, option B is actually incorrect because uranium fuel rods are indeed massive an amount and a challenge to transport, but not impossible. But these are two reasons that do not best explain exactly why uranium feel rods in nuclear reactors cannot be used in atomic weapons without further processing. So, again, option B is going to be eliminated from our choices. So, we can go ahead and move on to option C. This reads without further treatment, uranium field relative and nuclear reactors will explode during transportation of use for atomic weapons. So, for options see here this is also not the best answer because with or without further treatment treatment uranium fuel rods in nuclear reactors may explode during transportation if mishandled or if sufficiently triggered into a reaction. Also atomic weapons are really designed to explode at the determined moment when sufficiently triggered into a reaction now reading. So let's eliminate C. And moving on to statement D. This reads without further processing the U. 2 35 enrichment of uranium fuel rods and a nuclear reactor is not high enough to be fit for using atomic weapons. So option D. Is the best answer. Uranium fuel rods In nuclear reactors cannot be used in atomic weapons without further processing because of the enrichment of U. 235 in the field used for nuclear power plants is only around maybe 33%. Um as compared to greater than 85 enrichment of you 3 to 5 and they feel used in atomic weapons. So uranium fuel rods and nuclear reactors must be processed and sufficiently enriched and you 35 to be fit for nuclear weapons. So my final answer to this question is going to be statement D. Because this is going to be our best answer of the four
