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.

NRC okays construction permits for Hermes 2 test facility
The Nuclear Regulatory Commission announced yesterday that it has directed staff to issue construction permits to Kairos Power for the company's proposed Hermes 2 nonpower test reactor facility to be built at the Heritage Center Industrial Park in Oak Ridge, Tenn. The permits authorize Kairos to build a facility with two 35-MWt test reactors that would use molten salt to cool the reactor cores.

Providing adequate security to civilian nuclear materials and facilities exemplifies the long-standing, dynamic challenge of addressing the potential for facility damage under operational uncertainty. Estimating attack likelihood with enough precision to be useful and actionable for security risk management is philosophically, scientifically, and practically challenging. In response, this paper discusses the conceptual and analytical shortcomings of various approaches to calculating the likelihood of attack as a foundational element of security risk management. From these shortcomings emerge a set of characteristics that can guide the creation of alternative concepts that provide more robust and actionable security risk management approaches better aligned with the Ievolutionary growth in civilian nuclear facilities. Such broader conceptions would support movement from traditional interpretations of probability of attack toward more nuanced and complex depictions to enhance security risk management.
