In quickest review, NRC approves 20-year renewal for Robinson
The Nuclear Regulatory Commission has renewed the Robinson nuclear power plant’s operating license in record time, the agency announced last week.
The subsequent license renewal process for the Hartsville, S.C., facility was completed within 12 months, according to the NRC. The process has typically taken 18 months. This was the first license renewal review conducted under the directive of Executive Order 14300 to streamline processes like renewing operating licenses.

Nuclear fuel must be of high quality before being placed into service in a reactor. Nuclear fuel vendors currently use manual inspection for quality control of the nuclear fuel pellets before they are inserted into the zirconium fuel rods and bundled into assemblies. The feasibility of automating the pellet inspection process using artificial neural networks is examined to improve accuracy, speed, and cost; to reduce employee radiation doses; and to provide defect statistics to the fuel manufacturer. Sample nuclear fuel pellets (252 pellets) are photographed and scanned, and appropriate feature extraction techniques are developed and applied to the scanned images. The extracted features are then used as inputs to a backpropagation neural network. The results indicate that a backpropagation neural network is capable of classifying pellets as good (passing) or bad (failing) with high accuracy.
