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.”

The paper presents experimental data on plasma heating in a new regime of GOL-3 operation. Unlike previous experiments, the new regime features significant growth of energy of electrons in a relativistic electron beam during the beam pulse.The new dynamics of beam energy during the shot changes dynamics of plasma heating. A pronounced feature of previous GOL-3 experiments on plasma heating in the corrugated magnetic field was early transition to the plasma cooling stage, which in some regimes occurred much earlier than the beam injection stopped. In the gradual-energy-growth regime, plasma heating continues for a longer period until the beam power decreases significantly. Some other features will also be discussed.Experiments in the new regime allow us to partially verify feasibility of plasma heating with the electron beam at lowered beam parameters. This is important for the next planned step in GOL-3 program.
