The article discusses changes in the nuclear power industry. The industry has experienced a wide variety of adverse behaviors associated with design and operation of nuclear fuel. Significant crud buildup was identified as the primary cause for multiple fuel failures during the River Bend Station Cycle 11 refueling outage. Several advanced tests were obtained to gain insights into key relationships between reactor coolant chemistry constituents and fuel rod heat transfer mechanisms. The Nuclear Safety barrier from fission products is provided by the fued cladding. Radiological safety is also enhanced by the significantly reduced personnel.
