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.

PG&E to dredge Diablo Canyon intake system
The owners of the Diablo Canyon nuclear power plant plan to dredge a massive buildup of shoaled sediment from its seawater intake cove.
Pacific Gas and Electric spokesperson Suzanne Hosn said, “The dredging project in the Diablo Canyon marina will remove approximately 70,000 cubic yards of sediment to prevent circumstances that could impact the power plant’s cooling system. Dredging will take place for the first time since operations began because of a rapid increase in sediment.”

Various methods for accelerating targets to be injected into an Inertial Fusion Energy (IFE) power plant have been considered such as gas gun, rail gun and electromagnetic induction. One method that could also be used for direct drive targets is electrostatic acceleration.We have been using electrostatic steering to improve target placement accuracy. We optically track the motion of a charged target, and feed back appropriate steering voltage to four steering electrodes. We have also completed fabrication and begun testing of an electrostatic accelerator that advances the electric field each time the charged target passes one of the 96 accelerating electrodes. Many of the accelerating electrodes are segmented to allow transverse position correction based on transverse position measurements during the acceleration process. Calculations indicate that this "first step" accelerator will achieve 10-15 m/s target velocity in 0.9 m with ±4 kV accelerating voltage. Updated target steering results as well as the accelerator design, fabrication, and early experimental results are presented.
