ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

Technical Paper | Advances in Nuclear Fuel Management - Increased Enrichment/High Burnup and Light Water Reactor Fuel Cycle Optimization | doi.org/10.13182/NT05-1
Articles are hosted by Taylor and Francis Online.
Boiling water reactors (BWRs) in the United States have transitioned over the past 30 yr from 7 × 7 and 8 × 8 fuels, 12-month cycles, and batch average burnups of 30 GWd/tonne U to 10 × 10 fuel, 18- to 24-month cycles, batch average burnups of 50 GWd/tonne U, and 5% power uprates in the 1990s. The next step for BWRs in the new millennium is 24-month cycles and extended power uprates as high as 120% power. These operating conditions lead to large reload fuel batch sizes (up to 45% of the core) that result in lower batch average discharge burnups (~45 GWd/tonne U). Parameters driving the drop in fuel burnup include enrichment limitations and the need for fuel performance improvements. The next steps to achieve better BWR fuel cycle economics and their associated benefits and implementation challenges are discussed in this paper.
