Dominion to Seek 80-Year Lifetime for North Anna Nuclear Reactors

November 20, 2017

Dominion Energy will formally ask the Nuclear Regulatory Commission (NRC) to relicense its two reactors at the North Anna Power Station for 20 more years—effectively extending their operating lives up to 80 years.

Dominion Energy Virginia notified the federal regulatory body of its intent to relicense the two reactors in Louisa County, Virginia, which it will file in 2020. The company in November 2015 notified the NRC of its intent to seek a 20-year license renewal of its two units at the Surry power station, in southeastern Virginia, during the spring of 2019.

The 1,892-MW North Anna plant’s Unit 1 began commercial service in 1978 and Unit 2 in 1980. The 1,676-MW Surry plant’s Unit 1 began commercial service in 1972 and Unit 2 in 1973. All four units’ licenses were renewed for 20 years in March 2003. The North Anna’s units are currently authorized to operate until between 2038 and 2040. At Surry, the reactors are licensed until 2032 and 2033.…

FERC’s Chatterjee Has Interim Plan to Prop Up Coal, Nuclear Plants

Federal Energy Regulatory Commission (FERC) Acting Chairman Neil Chatterjee, who has said he is “sympathetic” to a rule that would help prop up struggling U.S. coal and nuclear power plants, apparently is ready to move forward with an interim plan to keep financially troubled plants operating while his agency continues to consider a market-changing cost proposal from the Department of Energy (DOE).

Utility Dive on November 15 reported that Chatterjee is “considering regulatory action,” saying FERC could issue a “show cause” order directing regional transmission organizations (RTOs) and independent system operators (ISOs) to update market tariffs to keep baseload plants, or those with “necessary resilience attributes,” operating or show why those plants should not continue to remain online. That would provide time for FERC to institute rules regarding electricity grid resilience and market compensation.

Chatterjee, who said he has not detailed his plan with other FERC staff, told Utility Dive his proposal would be “messy” and “uncomfortable.”…

Startup of Olkiluoto 3 Nuclear Plant Delayed Again

Continued problems with construction of the Olkiluoto 3 nuclear power plant in Finland have pushed the facility’s expected start date into 2019, meaning operations will not begin until at least 10 years after the original proposed start of commercial service.

Project owner Teollisuuden Voima Oyj (TVO) on October 9 announced further delays. TVO project director Jouni Silvennoinen in a statement said: “We are very disappointed by this additional delay. There is still substantial work to be accomplished in the project.”

The 1.6-GW Olkiluoto 3 project is being built by a group led by Areva, France’s state-owned nuclear group. The nuclear plant, where construction began in 2005, was originally expected to begin operation in 2009. According to an October 9 Reuters story: “An Areva spokesman said the reactor would produce its first power at the end of 2018, but the ramp-up to full production would delay the commercial start-up to May 2019. He said hot-testing would start in December 2017, nuclear fuel would be loaded in August 2018, first grid connection would be in December 2018 and the commercial start would be May 2019.”…

Entergy Gives Palisades Nuclear Plant Five More Years to Run

Entergy Corp. will keep the Palisades nuclear power plant in Covert, Michigan, open until the spring of 2022, owing to a shortfall in recovery granted to Consumers Energy by state regulators.

In a bid to actively exit the merchant nuclear power business, investor-owned Entergy had decided to shutter the 798-MW plant by October 1, 2018. “Market conditions have changed substantially, and more economic alternatives are now available to provide reliable power to the region,” it said when it announced its decision about a year ago.

The decision came as a surprise because Entergy has a power purchase agreement with Consumers Energy—Michigan’s largest utility and the principal subsidiary of CMS Energy—which committed the company to buying nearly all the power generated at Palisades through April 2022. Entergy reasoned the plant’s closure could save Consumers’ customers as much as $ 172 million over four years, even after Consumers paid Entergy $ 172 million to terminate the contract.

On September 22, however, the Michigan Public Service Commission granted Consumers a recovery of only $ 136.6 million of the $ 172 million it requested for the buyout of the power purchase agreement. …

Florida Nuclear Plants Will Shut Ahead of Irma

Florida Power & Light (FPL), the largest utility in Florida, said September 7 it would shut down its Turkey Point and St. Lucie nuclear power plants in the hopes of limiting potential damage from Hurricane Irma. The facilities are the only operating nuclear plants in the state.

FPL did not give specific timing for the shutdown, but the Nuclear Regulatory Commission (NRC) said it expects Turkey Point, located south of Miami, will be taken offline the evening of September 8, with the St. Lucie facility on Hutchinson Island, north of West Palm Beach, likely being shut down early on September 9. The effects of Irma, which could be the most-destructive hurricane to ever strike Florida, are expected to be felt in south Florida on Saturday, with conditions worsening throughout the weekend.

The two plants are each about 20 feet above sea level. The plants are protected by concrete and steel barriers, and were further reinforced for protection after the 2011 Fukushima nuclear disaster in Japan, when floodwaters from a tsunami after an earthquake caused multiple meltdowns at the Fukushima Daiichi Nuclear Power Plant.…

UPDATED: SCANA, Santee Cooper Abandon V.C. Summer AP1000 Nuclear Units, Citing High Costs

SCANA Corp. and Santee Cooper have ceased construction of Units 2 and 3 at the V.C. Summer Nuclear Station in South Carolina.

The project owners said the decision, prompted by analysis of detailed schedule and cost data, would save customers nearly $ 7 billion. The project, which was about 64% complete, has been in limbo since key contractor Westinghouse filed for bankruptcy in March.

The decision comes just days after Westinghouse’s parent company Toshiba agreed to pay the two project owners nearly $ 2.2 billion to cap its liabilities from the unfinished nuclear project. Toshiba reached a similar $ 3.7 billion agreement with Southern Co. in June as it seeks to limit its liabilities from the Vogtle project. Both AP1000 nuclear projects are years behind schedule and billions of dollars over budget.

Construction continues at the two Vogtle AP1000 units in Georgia. A project owner, Georgia Power, on July 28 told POWER that it expects to complete the cost-to-complete and schedule assessment by the end of August.…
