Question 14

Medium

A deep-sea research station is powered by a small modular nuclear reactor.

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

[1]

The reactor operates at a steady electrical power output of $MW35\text{ MW}$ . Calculate the total energy output of the reactor during a continuous operational run of $hours6.0\text{ hours}$ . Give your answer in joules ( $J\text{J}$ ) in standard form (scientific notation).

[3]

In a standard year of $days365\text{ days}$ , the research station's reactor was online and generating power for $92%92\%$ of the year. Calculate the number of days during that year that the reactor was online. Give your answer to the nearest whole day.
