A 900-MW powerplant of the pressurized-water nuclear-reactor type uses once-through cooling from a river. Regulations do not permit cooling water discharge back to the river hotter than 5°C above river ambient. Estimate a.) the necessary water flow, in kg/s, and b.) the reduction, in percent, in this water flow if the plant efficiency is improved by 1 percentage point. Take cp for water = 4.184 kJ/kg·K
Note:
Answer for a.) is 8.73 *10^4 kg/sec (Please show work)Also, Please solve b.) with work
