    How much mass is produced? The nuclear power plant essentially converts mass into energy -- mass is not produced, it is consumed.

    Ok, sorry for my bad language. How much mas is equal to the energy as being used under a year.

    Offcourse i know E=mc^2 but how do i convert the watt to energy and calculate the mas under a year.

    A watt is a Joule per second. So you've got 10^9 of them times the number of seconds in a year.
