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.

EPA issues final rule regulating “forever chemicals”
The Environmental Protection Agency announced that it will issue a rule aimed at limiting public exposure to per- and polyfluoroalkyl substances (PFAS). The final rule will designate two widely used PFAS chemicals, perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), also known as Superfund.
According to the EPA, both PFOA and PFOS meet the statutory criteria for designation as hazardous substances.

Most operating nuclear power plants (NPPs) in the United States have received approval to extend their operating licenses to 60 years. Now the nuclear industry is preparing to extend operating licenses to 80 years. While NPPs are preparing for extensions (60 years and beyond), the nuclear industry is facing a unique economic sustainability challenge in the current energy market. This is partly because the domestic nuclear industry is dependent on a high number of skilled workers to perform operation and maintenance activities. This labor-centric business model is cost prohibitive and results in high operations and maintenance costs. One of the activities performed by skilled workers in a NPP on a regular basis is manual concurrent or independent verification of manual valve position. This activity presents human error opportunities, operational and safety challenges, and regulatory compliance impacts, in addition to high labor costs. To address these concerns, a wireless valve position indication sensor technology is developed and matured by Idaho National Laboratory. In this paper, advancements achieved in the design, development, testing, and demonstration of a prototype wireless valve position indication sensor system are presented. The paper presents the electromagnetic interference evaluation of the prototype; design and development of three-dimensional (3-D) adjustable and reconfigurable universal sensor mounting units; improved quality-of-service and reliability of wireless communication; and demonstration of the technology on an experimental flow-loop fitted with nine manual valves for different valve configurations.
