Minimum quantity of fuel is required
Thermal power plant
Nuclear power plant
Diesel power plant
Gas power plant
Nuclear power plant
Nuclear power plants have the highest energy density among conventional power generation methods, requiring a minuscule quantity of fuel compared to fossil fuel plants. This is because nuclear fission releases an enormous amount of binding energy from the nucleus, whereas thermal plants rely on the relatively small chemical energy released from molecular bonds.

E=Δmc2 — Einstein's mass-energy equivalence formula describing energy release during fission
Q=m⋅Cp⋅ΔT — Basic heat transfer principle in the coolant loop
Nuclear fission involves bombarding heavy nuclei like 235U with neutrons, causing them to split into smaller nuclei. This process releases a significant amount of heat energy according to Einstein's mass-energy equivalence principle, E=Δmc2. This heat is then used to generate steam, which drives a turbine connected to an electrical generator.
Nuclear fuel (235U) provides approximately 2-3 million times more energy per unit mass than burning coal.
Nuclear plants provide base-load power with negligible greenhouse gas emissions during operation.
Energy density is the primary driver behind the minimal fuel storage requirements for nuclear stations.
Extremely high energy density
Low fuel storage and transportation requirements
Continuous power generation capacity
High initial capital investment
Complex radioactive waste management
Stringent safety and security protocols
Large-scale base-load power generation
Naval propulsion (submarines and aircraft carriers)
| Feature | Nuclear Plant | Thermal (Coal) Plant |
|---|---|---|
Fuel Energy Density | Very High | Low |
1 kg of 235U produces energy equivalent to roughly 2,500 to 3,000 tonnes of coal.
Thermal, Diesel, and Gas plants require massive continuous fuel supply chains, which are logistically intensive compared to nuclear plants.
B is correct — Nuclear power plants utilize nuclear fission, which releases significantly more energy per unit of fuel mass than the chemical combustion used in other power plant types.
Always relate fuel requirement inversely to the energy density of the fuel source; nuclear > gas > oil > coal.
