After decades of planning and weeks of preparation and checks, the first batch of legacy waste has been retrieved from the Pile Fuel Cladding Silo at the Sellafield nuclear site in West Cumbria, England. According to Sellafield Ltd., the site license company, a state-of-the-art robotic arm was used to reach into the silo and, for the first time, remove and repackage the waste for longer-term storage.

These retrievals mark a significant achievement in progress toward the cleanup and decommissioning of one of the most hazardous buildings on the site, according to Sellafield Ltd., which made the announcement on August 16.

To expand interim storage of vitrified high-level radioactive waste at the Savannah River Site, the Department of Energy’s Office of Environmental Management and its liquid waste contractor Savannah River Mission Completion (SRMC) have double stacked 2,000 canisters in one of the site's two glass waste storage buildings (GWSB). GWSB 1 consists of a below-grade, seismically qualified concrete storage location containing support frames for the vertical storage of 2,262 10-foot-tall canisters.

The Department of Energy’s Office of Environmental Management announced that the first batches of glass-forming beads, called frit, were poured last week into a melter at the Hanford Site’s Waste Treatment and Immobilization Plant (WTP), also known as the Vit Plant. The melter, which has been heated to 2,100ºF, will be used to immobilize Hanford’s radioactive and chemical tank waste, turning it into a stable glass form through vitrification.

Sellafield Ltd., a subsidiary of the U.K. government’s Nuclear Decommissioning Authority, announced that drone pilots have successfully completed two firsts in the use of unmanned aerial vehicles (UAV) at the Sellafield nuclear site in Cumbria, England.

According to the company, the flights, which accessed a Sellafield building with limited space using a light detection and ranging (lidar) sensor and a radiation dosimeter, are helping improve the safety of employees during the decommissioning of the site’s legacy buildings.

Mapping flight: First, an Elios 3 drone equipped with a lidar sensor was able to successfully collect data from a site building. The data will be processed to produce a 3D model of the area, which will help inform engineering decisions. According to Sellafield, the mapping flight marks a major milestone for the site’s UAV team, enabling unparalleled efficiency in mapping and 3D modeling.

The Department of Energy’s Carlsbad Field Office announced that it has made a significant step toward increasing airflow to the Waste Isolation Pilot Plant (WIPP) underground with the excavation of a new utility shaft. According to the office, crews working on the shaft recently reached an underground depth, known as station depth, that will allow horizontal tunneling work to begin on connecting the shaft to the WIPP repository complex.

Located in southeastern New Mexico, the repository for defense-related transuranic waste sits 2,150 feet below ground level. Airflow to the underground has been restricted following a radiological release in 2014.

When completed, the 26-foot-diameter utility shaft will provide air to WIPP’s new ventilation system, called the Safety Significant Confinement Ventilation System (SSCVS). The increased airflow provided by the system will allow for simultaneous mining, rock bolting, waste emplacement, and maintenance operations.
