← ScienceWhich outcome occurs when the fuel density drops excessively inside a Tokamak fusion reactor?
A)Increased plasma instabilities develop rapidly✓
B)Neutron flux against walls increases
C)Electron temperature briefly reverses sign
D)Deuterium-tritium cryogenic pumping failures begin
💡 Explanation
Increased plasma instabilities develop inside the Tokamak because reduced density decreases the collision rate. Therefore, magnetic confinement weakens; rather than high neutron flux because fusion ceases with lower pressures and reactions diminish.
