Separative Work Unit

  1. Feb 15, 2015 #1
    Hello Guys,

    I am a mechanical engineering student and taking nuclear engineering course. Professor told me to search SWU (separative work unit). I know the general formula and the value function... But I need the derivation of that formula from entropy... Is there any document that you can suggest? I checked possible books to find out but could not get a satisfactory result. They just put the formula and say here is the value function and this is the formula for SWU. I do not want to present my topic like that. I read in a website that the value function comes from change in entropy for the gas.

    Thanks in advance.

    Entropy of a mixture is R times the sum of xilnxi , where the xi are the mole fractions of the components of the mixture. That's your starting point.
