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.
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.

NRC awards R&D grants as part of University Nuclear Leadership Program
The Nuclear Regulatory Commission’s Office of Regulatory Research recently awarded 20 new research and development grants in the University Nuclear Leadership Program (UNLP). The grants, totaling $9,998,188, are derived from the $16 million that Congress appropriated for the program for fiscal year 2022. The 20 selected proposals were among the 89 that were submitted to the NRC and peer-reviewed by the commission staff and experts from academia.

The thermal scattering data for H in H2O are adjusted to better fit a series of criticality safety benchmarks using the Petten adjustment method for optimizing nuclear data. This method is based on the “Total Monte Carlo” approach developed for nuclear data uncertainty propagation to a large-scale system, together with a selection based on a global distance to specific criticality benchmarks. This paper demonstrates the possibility to improve the agreement with integral benchmarks by modifying the thermal scattering data. It is an additional step toward defining a globally adjusted nuclear data library with the Petten adjustment method, including thermal scattering data and nuclear data at higher energy.
