>a fusion reactor needs 1 T and 1 D for reaction>this reaction will generate ~20MeV of energy>to produce 1 T you need to bombard 1 D with 1 neutron>to generate that 1 neutron you will need 1 fission reaction, which will generate ~2.5 neutrons and with 80% neutron efficiency will give you the 1 extra neutron required>this 1 fission reaction will generate ~200MeV of energyso basically the fuel plant that feeds that fusion powerplant will generate 10x the amount of energy of the fusion power plant. Doesn't this prove that fusion is a total scam?>inb4 muh D-D reaction muh neutron multiplier muh aneutronic neutron generator muh pie in the sky magical space tech that barely scrapes the edges of our physical reality
>>16978829>>to produce 1 T you need to bombard 1 D with 1 neutronIncorrect. Try again but use Google first.
>>16978829>fusion is a total scamIt is, but for different reasons: https://thebulletin.org/2017/04/fusion-reactors-not-what-theyre-cracked-up-to-be/
>>16978829>has zero understanding of nuclear physics >makes absurd claimsseriously you have two choices: read/study about this topic to eliminate your ignorance, or I suggest you kys
>>16978829>to produce 1 T you need to bombard 1 D with 1 neutronNeutron capture by deuterium to produce tritium has a fucking pitiful cross section, a maximum of about a millibarn. Most tritium is generated at low-temperatures using the Li-6 method which has a cross section of almost 1000 barns. Fusion research is currently looking at incorporating breeding blankets of Li to create a sustaining chain of T production in reactors, but the cross section plummets to like 20-30 millibarns by the time you get up to DT fusion temperatures so it's not a terribly efficient option.As for your energy - Li-6 production of T nets 4.8 MeV and DT fusion nets another 17.6 MeV per reaction. So that's only 22.4 MeV for a complete cycle, not 200 MeV. You're off by a fucking order of magnitude.
