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.

Constellation seeks subsequent license renewal for Dresden
Constellation Energy has filed with the Nuclear Regulatory Commission for a subsequent license renewal for its Dresden nuclear power plant in Illinois. The extension would allow Dresden to run through 2051.
The filing begins a comprehensive, multiyear review by the NRC. Unit 2 is currently licensed to operate through 2029 and Unit 3 through 2031. The facility’s license was first renewed by the NRC in 2004.

A high-power, wide-band, steady-state amplifier was developed as a part of research and development for ion cyclotron range of frequency (ICRF) heating in the Large Helical Device at the National Institute for Fusion Science. A double coaxial cavity was adopted to cover the wide frequency range of 25 to 100 MHz. An analysis of this cavity is compared with results of static tests, and good agreement is shown. In a high-power test, long-pulse operation of 5000 s at an output power of 1.6 MW, which is a world record for steady-state operation of an ICRF amplifier, has been achieved as a low-impedance-mode operation is adopted. Cooling of various elements of the amplifier is important in the steady-state operation. This paper reports how the steady-state operation is obtained through cooling. An analysis of heat removal in response to the temperature rise of a coaxial cable is also reported.
