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.

ITER cryogenic system is in its final design phase to be constructed at Cadarache, South of France. It shall use the most advanced cryogenic technologies developed for accelerators projects adapted and optimized to fulfil the requirements and constraints of a large fusion installation.A refrigeration capacity equivalent to 65 kW at 4.5 K is planned for the cooling of superconducting magnets, their HTS current leads and small users. It also includes the cooldown of the cryogenic pumps and their re-cooling after regeneration. A 1300 kW nitrogen plant provides cooling power for the thermal shields. The key design requirement is the capability to cope with large pulsed heat loads deposited in the magnets due to magnetic field variations and neutron production from the fusion reaction.The cryogenic distribution system is based on the design of a complex and compact transfer line system and several cryogenic distribution and feed boxes.After recalling the basic features we shall present the status of the design and the main magnet interfaces and key design requirements.
