Energy Released vs Total Mass of Reactants
सूत्र
## Nuclear Fusion Energy Fusion of light nuclei releases energy because the products have higher binding energy per nucleon. The energy comes from the mass difference, just like fission. ### Formula **E = delta_m × 931.494 MeV/u** The D-T fusion reaction (²H + ³H → ⁴He + n) releases 17.6 MeV. Per unit mass, fusion fuel releases about 4 times more energy than fission fuel, making it the ultimate energy source.
हल किया गया उदाहरण
D-T fusion: D(2.0141) + T(3.0164) → He-4(4.0026) + n(1.0087) + energy.
- 01Reactant mass = 2.0141 + 3.0164 = 5.0305 u
- 02Product mass = 4.0026 + 1.0087 = 5.0113 u
- 03delta_m = 5.0305 - 5.0116 = 0.0189 u
- 04E = 0.0189 × 931.494 = 17.6 MeV
अक्सर पूछे जाने वाले प्रश्न
Why is fusion so hard to achieve?
Both nuclei are positively charged and repel each other strongly. Overcoming this Coulomb barrier requires temperatures of 100 million °C or more. Containing this plasma is the central engineering challenge.
What is the most promising fusion reaction?
D-T (deuterium-tritium) has the lowest ignition temperature and highest cross section. D-D and D-He3 are harder but produce fewer neutrons. Proton-boron (p-B11) is aneutronic but requires much higher temperatures.
How much energy does 1 kg of D-T fuel produce?
About 3.4 × 10¹⁴ J (340 TJ), equivalent to about 80,000 tons of TNT. One gallon of seawater contains enough deuterium for the equivalent of 300 gallons of gasoline.
