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.

Part II extends the work of Part I on probability distribution of power during a low source re-actor startup, by using a mathematical model in which the assumption of zero neutron lifetime is no longer made. This permits calculations to be carried to and beyond prompt critical, and consequently permits consideration of faster reactivity insertion rates than could be handled by the methods of Part I. A computational technique for the finite lifetime model is described. Numerical results are given, which extend the results of Part I.
