Expert Answer
Total energy produced/sec = 1MW  =106watt =1000000 joule per sec
energy released/ fusion =17.6 MeV
                                   =17.6 x 1.6 x10-13J
                                   =28.16 x 10-13J
hence, Number of fusions/sec =(106)/(28.16 x 10-13)
                                           =35.51 x 1016
