← ScienceWhich outcome results when protium is completely depleted in a fusion reactor using deuterium and tritium fuel?
A)Increased hard X-ray bremsstrahlung radiation
B)Decreased neutron flux from reduced fusion✓
C)Accelerated erosion of the reactor walls:
D)Instability from increased alpha particle confinement
💡 Explanation
When protium is severely depleted, the overall fusion reaction rate drops because D-D, D-T reactions now dominate; reduced fusion lowers neutrons produced. Therefore a significant reduction in neutron flux results, rather than increased radiation, wall erosion, or changed alpha confinement, stemming from reduced fusion reactivity.
