“Development of options to limit groundwater impacts from silo leakage” will be presented by Sellafield Ltd at 9:00 a.m. PDT on Wednesday, May 19, over ZoomGov. The seminar is open to the public as part of the Center for the Remediation of Complex Sites (RemPlex) seminar series.

The Magnox Swarf Storage Silos is a legacy waste storage facility at the Sellafield Nuclear Site in northwest England. Sellafield Ltd is removing the wastes from the building and exporting them to a modern storage system, but the historical leaks belowground mean considering the potential for leakage during waste retrieval activities. 

The seminar will cover the leak management plan, in situ chemical treatment, groundwater capture, ex situ treatment, results from laboratory testing, and the potential benefits and detriments of these techniques.

Sellafield Ltd is a Nuclear Decommissioning Authority company registered in England and Wales. The speakers are Nick Atherton, a Chartered Environmentalist and Sellafield’s strategy leader for the Retrievals Value Stream, and James Graham, PhD, a geoscientist specializing in land quality issues on UK Nuclear license sites.
