Siphoning D&D lessons from the oil and gas industry

NextEra Energy will be allowed to revise the emergency preparedness plan for its Duane Arnold nuclear power plant to reflect the plant’s decommissioning status, having been granted exemptions from the Nuclear Regulatory Commission’s emergency preparedness and planning requirements, the agency announced on February 17. A single-unit boiling water reactor plant located in Palo, Iowa, approximately eight miles northwest of Cedar Rapids, Duane Arnold was shut down in August 2020 after a derecho damaged the plant’s cooling towers.

The NRC regularly issues exemptions from its licensing requirements to nuclear power plants that are transitioning to decommissioning, where the risk of an off-site radiological release is significantly lower, and the types of possible accidents significantly fewer, than at an operating reactor.

Once NextEra implements the exemptions, state and local governments can rely on comprehensive emergency management (“all hazard”) planning for off-site emergency response should an event occur at Duane Arnold. As a result, there will not be a 10-mile emergency planning zone as currently identified in Duane Arnold’s license. The plant will maintain an on-site emergency plan and response capabilities, including the continued notification of state government officials in the event of an emergency declaration.

The Nuclear Regulatory Commission has updated its guidance for nuclear power plant owners and operators in estimating the cost of decommissioning their reactors. Licensed power reactor operators are required under NRC regulations to annually adjust the estimated costs (in current year dollars) of decommissioning their plants to ensure that adequate funds are available when needed.

NUREG-1307, Revision 18, Report on Waste Burial Charges: Changes in Decommissioning Waste Disposal Costs at Low-Level Waste Burial Facilities, issued on February 3, explains the formula acceptable to the NRC for determining the minimum decommissioning fund requirements for nuclear power reactor licensees. Specifically, NUREG-1307 provides the adjustment factor and updates the values for the labor, energy, and waste burial escalation factors of the minimum formula.

The Nuclear Regulatory Commission has opened for public comment the license transfer proceedings for the Palisades nuclear power plant, with the opportunity to request a hearing and petition for leave to intervene. Notice of the open proceedings was published in the February 4 Federal Register. Deadlines are February 24 for requests for a hearing and March 8 for comments.

In December, Entergy Corporation and Holtec International jointly submitted an application to the NRC for approval of the transfer of the licenses for the Palisades nuclear plant–located in Covert, Mich.—to Holtec, following the plant’s permanent shutdown and defueling in the spring of 2022. The application also requests approval of the license transfer of Entergy’s decommissioned Big Rock Point facility near Charlevoix, Mich., where only the independent spent fuel storage installation (ISFSI) remains.

New York Attorney General Letitia James filed a lawsuit on behalf of the State of New York against the Nuclear Regulatory Commission over the sale of the Indian Point nuclear power plant to subsidiaries of Holtec International for decommissioning.

Filed in the U.S. Court of Appeals for the District of Columbia Circuit on January 22, the suit challenges the NRC’s denial of New York’s petition for a hearing regarding the transfer of Indian Point’s licenses from owner Entergy to Holtec, as well as the NRC’s initial approval of the license transfer. The NRC approved the transfer in November 2020 while challenges from the state and other groups were still being adjudicated. The NRC issued its order denying New York’s petition to intervene on January 15.

The transfer of ownership of the plant from Entergy to Holtec is targeted to occur after Indian Point-3 shuts down in April 2021. Indian Point-2 permanently ceased operations in April 2020, and Indian Point-1 has been shut down since 1974. The pressurized-water reactors are located in Buchanan, N.Y., approximately 24 miles north of New York City.

The Nuclear Regulatory Commission has extended for two months the public comment period for its draft decommissioning guidance, Consolidated Decommissioning Guidance, Characterization, Survey, and Determination of Radiological Criteria (NUREG-1757, Volume 2, Revision 2).

Britain and Japan have signed a research and technology deployment collaboration to help automate nuclear decommissioning and aspects of fusion energy production. According to the U.K. government, which announced the deal on January 20, the £12 million (about $16.5 million) U.K.–Japanese robotics project, called LongOps, will support the delivery of faster and safer decommissioning at the Fukushima Daiichi reactors in Japan and at Sellafield in the United Kingdom, using long-reach robotic arms.

The four-year collaboration on new robotics and automation techniques will also be applied to fusion energy research in the two countries.

Funded equally by U.K. Research and Innovation, the U.K.’s Nuclear Decommissioning Authority, and Japan’s Tokyo Electric Power Company, the LongOps project will be led by the U.K. Atomic Energy Authority’s (UKAEA) Remote Applications in Challenging Environments (RACE) facility.

With the signing of a cooperation agreement by Orano and Korea Hydro & Nuclear Power at KHNP’s headquarters in Gyeongju on December 4, France and South Korea are poised to enhance collaboration in the decontamination and decommissioning of nuclear facilities, particularly in South Korea and Europe.

Orano said that the collaboration will give it access to the expertise of KHNP engineers, as well as to KHNP’s network of providers of nuclear engineering services, particularly in the fields of robotics, process industrialization, and quality.

KHNP, in return, will benefit from Orano’s experience in preparing and carrying out nuclear dismantling, with the company providing technical assistance and supplying skills and training. South Korean engineers will be included in the Orano dismantling and services teams.

The Nuclear Regulatory Commission has issued the draft report, Consolidated Decommissioning Guidance, Characterization, Survey, and Determination of Radiological Criteria (NUREG-1757, Volume 2, Revision 2), with a request for comments by February 8.

NUREG-1757, which is intended for use by applicants, licensees, and the NRC staff, was last updated in 2006. This latest revision addresses lessons learned and experience gained from the review of license termination plans, decommissioning plans, and final status surveys for licensees undergoing license termination since then.

Notice of the draft NUREG was published in the December 8 Federal Register.

The U.S. Department of Energy plans to provide up to $12 million for new research on nuclear data in support of crosscutting research. The aim of the program is to expand and improve the quality of data needed for a wide range of nuclear-related activities, from basic research in nuclear science to isotope production and nuclear nonproliferation efforts.

“Increasingly, precise data on the properties of atomic nuclei are central to enabling groundbreaking advances in medicine, commerce, and national security,” said Chris Fall, director of the DOE’s Office of Science, on December 7. “This program targets crosscutting opportunities to enhance the curation of existing nuclear data archives, as well as research to lay the groundwork for new applications in areas of national need.”

The Nuclear Regulatory Commission has approved the transfer of the license for Unit 2 of the Three Mile Island nuclear power plant from FirstEnergy Companies to TMI-2 Solutions, a subsidiary of Utah-based EnergySolutions. The approval, announced on December 2, is effective immediately, and the license will be amended to reflect the new ownership once the sale of TMI-2 is completed.
