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.

Fermilab center renamed after late particle physicist Helen Edwards
Fermi National Accelerator Laboratory’s Integrated Engineering Research Center, which officially opened in January 2024, is now known as the Helen Edwards Engineering Center. The name was changed to honor the late particle physicist who led the design, construction, commissioning, and operation of the lab’s Tevatron accelerator and was part of the Water Resources Development Act signed by President Biden in December 2024, according to a Fermilab press release.

Atmospheric tritium concentrations and organically bonding tritium OBT of pine needles at NIFS Toki site had been measured considering environmental safety of future deuterium plasma experiment by large helical device (LHD). Atmospheric tritium concentrations of three chemical forms such as water HTO, hydrogen HT and methane CH3T had been measured since 2004. Tritium concentrations of HTO, HT and CH3T were distributed around 2-23 mBq/m3, 6-11 mBq/m3 and 0.5-3 mBq/m3 respectively. The HTO concentration principally depends on humidity in air. Recent decreasing rate of HT concentration to half was estimated 19.4 years. The OBT concentration tends to decrease and the rate to half was almost 9.4 years. Also the OBT measurements were cross checked with burning and liquid scintillation counting method and 3He mass spectrometric method. Both analyzed results showed good agreement. Long term monitoring of environmental tritium would be necessary from view point of safety on future nuclear fusion development.
