Thermodynamic Efficiency and the maximum possible electric output

Click For Summary
SUMMARY

The thermodynamic efficiency of a 2.5GWth nuclear power plant operating at a high temperature of 570°K is calculated based on seasonal low temperatures. In winter, with a low temperature of 268°K, the efficiency is 53%. In summer, with a low temperature of 295°K, the efficiency drops to 48%. These efficiencies directly influence the maximum possible electric output of the plant, which can be derived from the efficiency calculations.

PREREQUISITES
  • Understanding of thermodynamic principles, specifically the Carnot efficiency formula.
  • Familiarity with temperature scales, particularly Kelvin.
  • Basic knowledge of nuclear power plant operations and output calculations.

1. A 2.5GWth nuclear power plant operates at a high temperature of 570°K. In the winter the average low temperature at which it dumps waste heat is 268°K; in the summer it’s 295°K. Determine the thermodynamic efficiency of the plant in each season, and then derive from it the maximum possible electric power output.

2. e = 1 – Tc/Th

Tc = Low Temperature
Th = High Temperature


3. Winter = 1 – (268/570) = 0.53 = 53%
Summer = 1 – (295/570) = 0.48 = 48%

The maximum possible electric output = ?
