Question 27

Medium

This question is about nuclear power station calculations.

Write down the equation which links energy ( $E$ ), power ( $P$ ), and time ( $t$ ).

[1]

A nuclear power station has a continuous power output of $MW650\text{ MW}$ . Calculate the energy output of this power station if it operates continuously for 4500 s. Give your answer in Joules ( $J\text{J}$ ) in standard form.

[3]

Nuclear power stations do not generate electricity every day of the year due to scheduled maintenance. A specific nuclear power station operated for 88% of a year (where $days1\text{ year} = 365\text{ days}$ ). Calculate the number of days during that year that the power station generated electricity.
