Here’s a look at some recent announcements from the Nuclear Regulatory Commission.

Summer SLR: The NRC this month published its final environmental impact statement for Summer Unit 1’s subsequent license renewal application. Dubbed a supplemental EIS, the report is an important step in determining if Dominion Energy can continue operating its 966-MWe Westinghouse pressurized water reactor unit for an additional 20 years beyond August 6, 2042, the current end of its license.

Mike Mlynarek believes in this expression: “In the end it will be OK; and if it’s not OK, it’s not the end.”

As the site vice president at Palisades nuclear power plant in Covert Township, Mich., Mlynarek is overseeing one of the most exciting projects in the United States nuclear power industry. If all goes according to plan, Holtec’s Palisades plant will be splitting atoms once again by the end of 2025 and become the first U.S. nuclear facility to restart after being slated for decommissioning.

The Nuclear Regulatory Commission is asking for public comments until March 3 on its environmental assessment (EA) and draft finding of no significant impact at Michigan’s Palisades nuclear power plant, where Holtec hopes to restart operations by the end of 2025.

The Department of Energy’s Gateway for Accelerated Innovation in Nuclear (GAIN) announced June 20 that two companies—one power plant operator and one advanced reactor developer—are getting vouchers to access the extensive nuclear research capabilities and expertise available across the DOE national laboratories in the third round of GAIN vouchers awarded for fiscal year 2024. 

A bipartisan group of nine House members is calling on the Department of Energy to give “fair, full, and swift consideration” to Holtec International’s application for DOE Loan Programs Office funding to restart the company’s Palisades nuclear plant, closed last year by the facility’s previous owner, Entergy.

Holtec International announced that it successfully loaded its 2,000th spent nuclear fuel canister this fall as part of the ongoing dry storage campaign at Entergy’s Arkansas Nuclear One (ANO) power plant in Russellville, Ark.

Spent fuel from ANO’s two pressurized water reactors is stored in Holtec’s MPC-37 multipurpose canister, each containing 37 PWR fuel assemblies in a prismatic basket made of Holtec’s Metamic-HT material in an egg-crate configuration. The company’s HI-STORM dry fuel storage systems have been in use at ANO since 2003.

Quote: Entergy’s chief nuclear officer, Kimberly Cook-Nelson, said, “We appreciate the strong partnership that we at Entergy have with Holtec. Arkansas Nuclear One is an important facility for our company, the industry, the state of Arkansas, and the Russellville community, and having the 2,000th spent fuel dry storage system is a key milestone for our continued safe, secure, and reliable operations.”

The Nuclear Regulatory Commission has granted Holtec Decommissioning International’s request to revise the emergency preparedness plan for the Palisades nuclear power plant in Covert, Mich., to reflect the plant’s decommissioning status.

Holtec International has taken another step on the arduous stairway to Palisades resurrection, announcing last Friday that it has filed with the Nuclear Regulatory Commission to “formally begin the process of seeking federal reauthorization of power operations” at the Covert Township, Mich., facility.

The Texas Advanced Nuclear Reactor Working Group—formed recently by the Public Utility Commission of Texas (PUCT) at the direction of Gov. Greg Abbott—hosted its first public meeting last Thursday to discuss the group’s organizational structure and outline a plan to turn Texas into a national leader in the use of advanced nuclear energy.

Holtec International has said its patented HI-LIFT crane technology, being installed at the Indian Point-3 nuclear power plant, will speed the defueling of the spent nuclear fuel pool and avoid millions in excess decommissioning costs.

The Palisades nuclear power plant may have entered retirement, but it’s not dead yet. Plant owner Holtec International is continuing with its unprecedented effort to restart the Covert, Mich., single-unit facility, shuttered 11 months ago by previous owner Entergy.

The Department of Energy has announced the release of application guidance for the second award cycle of its $6 billion Civil Nuclear Credit (CNC) Program.

Part of the Infrastructure Investment and Jobs Act—the $1.2 trillion bipartisan measure signed by President Biden in November 2021—the CNC Program was established to prevent the premature retirement of economically challenged nuclear power plants in recognition of the crucial role the Biden administration sees nuclear playing in achieving its ambitious decarbonization goals, including 100 percent clean electricity by 2035.

Holtec International is apparently not ready to give up on the Palisades nuclear power plant just yet. Despite having been denied federal funds last month for a possible reopening of the Covert, Mich., facility, the company this week announced its intention to reapply.

New Orleans-based Entergy Corporation yesterday announced changes to its senior leadership, including the selection of Kimberly Cook-Nelson as executive vice president and chief nuclear officer, replacing Chris Bakken.

Cook-Nelson, Entergy’s first female CNO, will be based in Jackson, Miss., the company’s nuclear operations headquarters. She joined Entergy in 1996 as a design engineer at the Waterford nuclear plant in Killona, La., rising to general manager of plant operations in 2011. Most recently, she held the position of chief operating officer, nuclear operations. (In addition to the Waterford facility, Entergy owns and operates Arkansas Nuclear One in Russellville, Ark., Grand Gulf in Port Gibson, Miss., and River Bend in St. Francisville, La.)

The Nuclear Regulatory Commission is increasing its oversight of the Waterford Steam Electric Station’s Unit 3 reactor due to a decade-long miscalibration of a radiation monitor.

In a September 13 letter to Entergy Operations, the NRC classified the issue at the Killona, La., facility as a “white finding”—agency parlance for a problem of low to moderate safety significance. (The NRC’s Reactor Oversight Process uses color-coded inspection findings and indicators to measure plant performance, starting at green and increasing to white, yellow, and red, commensurate with the safety significance of the issues involved.)

Maybe hold off commenting on those Palisades decommissioning plans for now: Michigan Gov. Gretchen Whitmer last Friday penned a letter to energy secretary Jennifer Granholm pledging state support for a Holtec International plan to restart the recently shuttered Palisades nuclear plant in Covert, Mich. It was Whitmer’s second letter to the Department of Energy head expressing support for Palisades and touting its value to the state.

Across the country, supply chain issues continue making the news: price escalation, inflation, logistical delays, scarcity of products and services, obsolescence, risk associated with just-­in-­time inventory, equipment and service quality, and—especially in nuclear—the financial pressures to reduce costs while maintaining our focus on safe, secure, and reliable plant operations.

Unfortunately, these are not new challenges for nuclear supply chain professionals.

In fact, in 2001, the Nuclear Energy Institute formed the Nuclear Supply Chain Strategic Leaders Group (NSCSL) in conjunction with the Institute of Nuclear Power Operations (INPO) and Electric Power Research Institute (EPRI) after an American Nuclear Society Utility Working Conference networking event. The NSCSL is composed of utility supply chain managers and directors and serves as the “community of practice” for these subject matter experts. I am privileged to be an NSCSL participant and an Entergy team member. The NSCSL was designed to be the industry go-­to group for materials and service collaborations and needed supply chain solutions.

While the Mississippi Public Service Commission earlier this year accepted a $300 million offer from Entergy Corporation to settle its portion of a multistate dispute with the utility over Grand Gulf nuclear plant customer rate impacts, the Arkansas Public Service Commission last week turned down its own $142 million offer, terming it “a low-ball amount.”

The Department of Energy earlier this year approved part one of a loan application from Holtec International for small modular reactor construction and invited the firm to apply for a loan to help build four of its SMR-160 units and grow its manufacturing capacity to produce the first wave of SMRs.

The Mississippi Public Services Commission has announced a $300 million settlement with Entergy Mississippi—the largest settlement in the MPSC’s history—ending the state’s part in multistate Federal Energy Regulatory Commission proceedings involving Grand Gulf plant customer rate impacts.
