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.

NRC v. Texas: Supreme Court weighs challenge to NRC authority in spent fuel storage case
The State of Texas has not one but two ongoing federal court challenges to the Nuclear Regulatory Commission that could, if successful, turn decades of NRC regulations, precedent, and case law on its head.

A simplified inexpensive apparatus was devised to irradiate specimens at liquid nitrogen temperatures (∼77°K) in a Dewar system. Provisions were also made to maintain the specimen at LN2 temperatures after irradiation for low temperature testing. Using the PSTR at a power level of 1 MW, a specimen can receive 1014 to 1015 n/cm2 integrated fast flux during an irradiation where the Dewar system is filled once. In addition to being inexpensive, the irradiation technique tends to minimize dangers resulting from possible explosions.
