Convert MeV to reactions/s ?

  1. Dec 12, 2006 #1
    1. The problem statement, all variables and given/known data
    Basically, I pretty much solved the problem I am working on. The fusion reaction I am working with is 2_1_H + 3_1_H --> 4_1_He + 1_0_n, and I determined the energy the reaction releases to be 17.5708 MeV. What I need to figure out now is how many of these reactions must occur per second to produce a power output of 15 MW.

    2. Relevant equations

    I was looking through the chapter and could not figure out which equations I can put together to solve this. But I did use E = deltam x c^2 to get my answer of 17.5708 MeV.

    3. The attempt at a solution

    I could not determine how to set up my work for this problem after going through the chapter. I was thinking of using the conversion factor for Curies, but I did not think it was relevant to my problem I am solving.

    This gave me an answer of 5.3356 x 10^18 reactions/s. Got it right. Thanks!
