The Department of Energy is preparing to demolish two large, complex facilities at the Nevada Nuclear Security Site with ties to historical nuclear propulsion rocket development and testing programs. The DOE’s Environmental Management (EM) Nevada Program and its environmental program services contractor, Navarro Research and Engineering, have begun characterization and hazard reduction work on the site’s Engine Maintenance, Assembly, and Disassembly (EMAD) and Test Cell C (TCC) complexes.

The Nuclear Regulatory Commission has issued a license to Interim Storage Partners (ISP), a joint venture of Waste Control Specialists and Orano USA, to construct and operate a consolidated interim storage facility for spent nuclear fuel in Andrews, Texas. Issued on September 13, the license comes just four days after Texas governor Greg Abbott signed a bill to block such a facility from being built in the state.

The Savannah River Site is reducing the flow of hazardous and radioactive metal contaminants to South Carolina’s rivers and streams by injecting a mix of clean water and baking soda into the site’s groundwater. The base mix neutralizes groundwater that has become acidic as a result of SRS’s chemical separations work, helping restrict the flow of contaminants.

The Nuclear Regulatory Commission has extended its orders transferring the licenses for the La Crosse and Zion nuclear power plants from EnergySolutions back to the plant owners until late 2022. This is the third time the NRC has extended the effectiveness of the license transfer orders for the decommissioned plants since approving them in 2019.

Pamela Cowan: The Fleet Approach to D&D

Pamela Cowen

Having spent more than 25 years in the commercial nuclear power community, Pam Cowan has spent time in both the front- and back-end operations of nuclear power. It is this experience that she draws upon as the senior vice president and chief operating officer of Holtec Decommissioning International (HDI) to help her build a growing fleet of power plants undergoing decommissioning and demolition.

Cowan, who came to HDI from the Nuclear Energy Institute, is also senior vice president of decommissioning and regulatory affairs for HDI parent company Holtec International and president of the Nuclear Asset Management Company, the owner of the plants. Cowan also serves as a member of the board of directors of Comprehensive Decommissioning International, a decommissioning general contractor, jointly owned by Holtec and SNC-Lavalin.

Radwaste Solutions spoke to Cowan about Holtec’s fleet approach to decommissioning and her plans for HDI.

(Editor's note: Soon after this article was published in Radwaste Solutions, Westinghouse Electric Company announced that Pam Cowan had been appointed president of the company's Americas operating plant services unit. Cowan takes over the business on September 21, following the retirement of current president, David Howell.)

Using basic hand tools and remote manipulators, operators at Savannah River Nuclear Solutions (SRNS) were able to reduce radiation exposure to workers performing cutter head maintenance in the Savannah River Site’s Tritium Extraction Facility (TEF).

According to SRNS, the innovative procedure proved to be an excellent example of real-world application of As Low As Reasonably Achievable (ALARA) principles of time, distance, and shielding.

Orano has delivered its first TN-LC spent nuclear fuel transport cask to Korea Hydro and Nuclear Power Company. The first use of the cask is planned for an international transport between South Korea and Sweden by the end of 2021.

KHNP received a license in June for the TN-LC transport cask from the Nuclear Safety and Security Commission, South Korea’s regulatory agency, for the transport of high-burnup spent fuel.

The Nuclear Waste Technical Review Board (NWTRB) has released a comprehensive and highly technical report on the Department of Energy's research efforts into high-burnup spent nuclear fuel. The NWTRB is an independent federal agency tasked with evaluating the technical and scientific validity of DOE activities related to managing and disposing of high-level radioactive waste and spent nuclear fuel.

The NWTRB report to the U.S. Congress and the secretary of energy, Evaluation of the Department of Energy’s Research Program to Examine the Performance of Commercial High Burnup Spent Nuclear Fuel During Extended Storage and Transportation, was posted to the board’s website on August 2. It is a product of a multi-year effort during which the NWTRB reviewed the DOE’s research activities into the performance of high-burnup spent nuclear fuel (SNF) in extended storage and transportation conditions.
