DTE Energy studying uprate at Fermi-2, considers Fermi-3’s prospects
DTE Energy, the owner of Fermi nuclear power plant in Michigan, is considering an extended uprate for Unit 2 that would increase its 1,100-MW generation capacity by 150 MW.

The sequence of three reactor-physics measurements as pedagogical experiments is discussed in regard to parameter interpretation, theory of measurement, and technique of measurement. The experimental apparatus and techniques were in part chosen for their teaching value; perhaps particularly significant is the technique for correcting the Np239 activity for the fission activity contribution. The time and equipment requirements are presented in detail, and some student results are briefly summarized.
