Recently, the Nawah Energy Company (Nawah) announced that the second unit (rated at 1400 MW) of Barakah nuclear power plant has been successfully connected to the national electric grid. This raises the total connected nuclear generated power to 2800 MW. It's expected that two more units will become online in the next few years, each rated at 1400 MW. a) How much of annual energy will the currently connected Al Barakah nuclear power units contribute to the national grid? b) Assume that gas turbines consume 0.21 m of equivalent natural gas for every 1 kWh of electricity produced, how much of gas (in m) will be saved due to the operation of the first two nuclear reactors (units)? c) How many tonnes of CO will be removed from the atmosphere as a result of bring the four units of Al Barakah nuclear power station online? Hint: use the below table which shows the amount of CO2 produced for every kWh generated by gas-fired turbines and nuclear power plants. Power generation technology Gas-fired power plants Nuclear power plants Amount of CO2 produced per each kWh generated (g/kWh) 400 12
