WIPP prepares to bring new ventilation system on line

Commissioning has begun on a new large-scale ventilation system at the Waste Isolation Pilot Plant in New Mexico.

The Safety Significant Confinement Ventilation System (SSCVS) is expected to increase underground airflow from 170,000 cubic feet per minute up to 540,000 cfm. The increased airflow will allow for simultaneous underground waste emplacement, mining, and ground control work. Ground control, including bolting, controls the movement of salt rock—known as salt creep—in the WIPP underground.

NRC releases decommissioned Zion site for unrestricted use

The Nuclear Regulatory Commission has released for “unrestricted use” most of the land on and around where the Zion nuclear power plant once operated in northeastern Illinois. This means that any residual radiation is below the NRC’s limits and there will be no further regulatory controls by the agency for that portion of the property.

Paradigm Shift: Monitoring Savannah River’s groundwater using artificial intelligence and machine learning techniques

Researchers at Savannah River National Laboratory (SRNL), in concert with Lawrence Berkeley National Laboratory, Massachusetts Institute of Technology, Pacific Northwest National Laboratory, and Florida International University, are leading the Advanced Long-Term Environmental Monitoring Systems (ALTEMIS) project to move groundwater cleanup from a reactive process to a proactive process, while also reducing the cost of long-term monitoring and accelerating site closure.

NRC approves emergency planning exemptions for defueled Indian Point

The Nuclear Regulatory Commission hasgranted a request by Holtec Decommissioning International (HDI) to revise the emergency preparedness plan for the Indian Point Energy Center. Reflecting the reduced risk of a radiological emergency at a decommissioning power reactor site, the exemption removes the requirement that HDI maintain a 10-mile emergency planning zone around the plant.

Sharing D&D Knowledge in a Competitive Market

Currently, the Nuclear Regulatory Commission is overseeing 17 nuclear power plants that are undergoing active decommissioning. For 10 of those plants, the NRC licenses have been transferred, either through sale or temporary transfer, from the plant owner and operator to a third party, nonutility company for decommissioning. To be profitable, those companies are decommissioning the nuclear plants as expediently as they safely can, while still protecting workers and the environment, using proprietary techniques and processes.
