**1. The problem statement, all variables and given/known data**

Effective Power generation of the plant is 5.43*[itex]10^{7}[/itex]W but it will required 9*[itex]10^{16}[/itex]J to be created.

Essentially the break-even will after solving equation Energy required/Power Generated however I get results of almost 50 years. Would this be correct?
