Division Spotlight
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

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 equilibrium phase diagram of the plutonium-cerium-copper system is presented, based on data obtained by differential thermal analysis, metallography and electron-microprobe x-ray analysis. Liquid-solid phase transitions were found between 419 and 1083°C. Ten crystalline phases solidify as primary phases from molten plutonium-cerium-copper solutions. No ternary compounds occur in the system. The ternary system is divided into two subsystems by the quasibinary section, CeCu2-PuCu2. Continuous solid solubility occurs along this join with neither a maximum nor a minimum. Solid solubility also occurs between the congruent compound, CeCu6, and the incongruent compound, Pu2Cu11. The ternary system is characterized by a single eutectic (4at.%Pu-68at.%Ce-28at.%Cu at 419°C), four peritectics, and two inversion points.
