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.
Nuclear Installations Safety
Devoted specifically to the safety of nuclear installations and the health and safety of the public, this division seeks a better understanding of the role of safety in the design, construction and operation of nuclear installation facilities. The division also promotes engineering and scientific technology advancement associated with the safety of such facilities.

New polls show substantial support for nuclear energy
Sixty percent of respondents in a recent national survey favored the use of nuclear energy, with only 25 percent opposing its use. While the latest Bisconti Research poll focuses on nuclear power and electricity generation, its findings on public interest in climate change and using a spectrum of sources to meet energy needs are consistent with a recent Pew Research Center poll on a broad set of energy policy and climate change topics. The approaches the two online surveys took to measuring public opinion on nuclear energy yielded different numbers but found some common ground.

The effects of thermal aging at a temperature range of 823 to 973 K on the mechanical properties and microstructure of JLF-1 and CLAM steels were investigated. The results showed that the hardness increased slightly and the creep properties improved after aging at 823 K for 2000 h, suggesting that strengthening occurred. However, softening took place by aging at 973 K for 100 h. The microstructural observation showed that there was no remarkable growth of lath width and grain size for the aged specimens. According to the microstructure and the model analyses, the increase in the density of precipitates, especially fine Ta-rich particles, are considered to be the main reason for the strengthening due to aging at 823 K for 2000 h. On the other hand, fine TaC precipitates were deduced to be dissolved due to aging at 973 K for 100 h. However, the change in precipitates alone cannot account for the softening occurred due to the aging.
