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
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

Construction begins on Kairos’s fluoride salt–cooled test reactor
Earlier today, on a site in Oak Ridge, Tenn., that was formerly home to the K-33 Gaseous Diffusion Plant, Kairos Power marked the start of construction on its low-power demonstration reactor. Named Hermes, the 35-MWt test reactor claims status as the first Gen IV reactor to be approved for construction by the Nuclear Regulatory Commission and the first non–light water reactor to be permitted in the United States in more than 50 years.

The total neutron cross section of carbon was measured over The energy range 1 keV to 15 MeV, using the U.S. National Bureau of Standards electron linear accelerator asa pulsed neutron source. Neutrom energies were measured by the time-of-flight method.The measurement accuracy is estimated to be ±¾% below 100 keV and ±1% above .The carbon cross section was fit with a polynomial from 0.001 to 1.4 MeV with the following coefficients σ = 4.757 − 3.419E + 1.548E2 − 0.328E3, where σ is in bams and E in MeV. Data are compared with other results.
