Complaint filed with FERC over Grand Gulf management
The Louisiana Public Service Commission (LPSC), the New Orleans City Council, and the Arkansas Public Service Commission on March 2 filed a complaint with the Federal Energy Regulatory Commission against Entergy Corporation, seeking damages of more than $360 million for what they term the utility’s “imprudent operation” of the Grand Gulf nuclear plant.
Located in Port Gibson, Miss., Grand Gulf is a single-unit plant with a 1,433-MWe boiling water reactor. The unit, which entered commercial operation in 1985, supplies power to customers of Entergy Louisiana, Entergy Mississippi, Entergy Arkansas, and Entergy New Orleans.

This study presents a thorough parametric neutronic analysis of a plate-based tristructual isotropic (TRISO) fuel particle bearing liquid salt–cooled reactor assembly. The analyses presented investigated the effects of altering fuel enrichment, packing fraction, plate region thicknesses, assembly structure thicknesses, assembly size, numbers of plates per assembly, use of burnable poison materials, replacement of assembly and plate carbon material with silicon carbide, and use of uranium nitride fuel kernels. The effects or trends observed included reactivity behavior, discharge burnup, cycle length, and other key design parameters such as moderator temperature coefficients, coolant density coefficients, control blade worth, and impacts upon power peaking (i.e., power and flux distributions).
This study is based upon two-dimensional lattice physics calculations involving the SERPENT 2 code and by using the nonlinear reactivity model as a reasonable tool for predicting discharge burnup. The reported results show that the system’s reactivity can be significantly altered by varying these design parameters, thus providing a starting point for future design optimization studies, and it is understood that future studies will need to be expanded to equilibrium full core analysis for more complete and accurate design and safety assessments, which is also a work in progress.
