NWTRB to hold public meeting on SNF disposal and corrosion
The Nuclear Waste Technical Review Board, an independent federal agency that evaluates the Department of Energy’s efforts to manage and dispose of spent nuclear fuel and high-level radioactive waste, will hold a two-day public meeting May 21–22 to review information on the DOE’s research and development activities related to the disposal of SNF and HLW in crystalline host rocks and on the corrosion of commercial SNF after disposal.

The fuel management optimization of a nuclear power plant is separable from the over-all optimum design. It has weak interactions with the core design and poison management which may be expressed by constraints upon the maximum permissible fuel burnup and ratio of peak-to-average power density (power peaking). Each time the reactor becomes subcritical, a decision must be made as to which fuel should be discharged and replaced and to what degree rearrangement is advantageous. This is a multistage decision process whose objective is the minimum power cost over the plant life. A dynamic programing algorithm and a computer program have been developed to optimize the refueling policies of a single-enrichment, three-zone, 1000-MWe PWR core for a minimum unit power cost. The major assumptions necessary for this method are the representation of the fuel composition by the sole parameter, burnup, and the prediction of the system behavior by least-squares polynomial curves fitted to prior calculations. These approximations have been verified and their accuracy is about 3%. Many problems are displayed to demonstrate the application of the method. The cost figures given in the numerical examples are for illustration purposes only and may not reflect current manufacturers' and utilities' policies.
