Hitachi May Scuttle UK Nuclear Project

January 14, 2019

Hitachi may cancel its plans for a $ 20.5 billion nuclear power project in Wales, according to several media reports from the UK and Japan. The Japanese company is expected to determine the fate of the project at a board meeting this week.

The Guardian newspaper was among those that in recent days reported an impasse in talks among Hitachi, UK officials, and the Japanese government regarding financing for the plant would likely lead to a cancellation. Hitachi already has spent about $ 2.6 billion on the project.

The Nikkei Asian Review on Jan. 11 reported that Hitachi’s board this week would likely move to suspend all work on the Wylfa Newydd plant. The power station on Anglesey island, on the north coast of Wales, was first proposed in 2009 as a 3,000-MW plant with two advanced boiling water reactors. Horizon Nuclear Power, a joint venture of E.ON and RWE, was behind the project. Hitachi bought the venture in 2012.

Two earlier 490-MW reactors at the Wylfa site, known as Reactor 1 and Reactor 2, became operational in 1971.…

Columbia Nuclear Plant Sets Another Generation Record, Credits Good Performance

Operators of the Columbia Generating Station have set a new generation record at the nuclear plant 12 miles north of Richland, Wash., sending more than 9.7 million MWh to the Pacific Northwest power grid during 2018.

The single 1,207-MW single GE-built Mark-2 boiling water reactor that is owned and operated by Energy Northwest—which comprises 26 public power member utilities across Washington state—has set new generation records five out of the past seven years.

Because the plant consistently surpassed generation records set first in 2012 (9.3 TWh), then in 2014 (9.5 TWh), and again in 2016 (9.6 TWh), the plant was a POWER magazine Top Plant in 2017. The plant won the award also due in part to an operations overhaul that began in 2009, when Columbia suffered a series of scrams that landed it on the Nuclear Regulatory Commission’s (NRC’s) radar, and led it to vastly improve its performance.

NERC: Accelerated Coal and Nuclear Retirements Pose Limited Reliability Risks

The accelerated retirement of coal-fired and nuclear generation by 2022 could adversely affect reliability in four regions, including in the east and over a swathe of the central U.S., the North American Electric Reliability Corp. (NERC) warned as it released findings from a “stress-test” scenario.

But the entity tasked with ensuring reliability and security of the North American bulk power system (BPS) also noted six of 10 assessment areas—which cover PJM, New England, MISO, the Electric Reliability Council of Texas (ERCOT), and the Western coast—would have enough generation capacity to maintain peak demand, even if they see high levels of generator retirements over the next five years.

A “Stress-Test” Scenario

The findings stem from NERC’s Dec. 18–released “Generation Retirement Scenario,” which the entity evaluated because, it said, the retirement of traditional baseload generators and their rapid replacement with natural gas–fired, wind, and solar generation “is changing the characteristics of the BPS and introducing new considerations for reliability planning.”

The so-called “stress-test” scenario essentially assumes that areas where coal and nuclear currently make up a large share of resource levels will see accelerated retirements so that by 2022, they will lose 30% of their coal capacity and 45% of their nuclear capacity.…

Plagued by Grim Challenges, Vogtle Nuclear Expansion Lags Behind Schedule, Says Oversight Consultant

The two-unit Vogtle expansion in Georgia faces major challenges that are poised to derail its schedule and ramp up costs—and the project is already behind schedule, a consulting firm tasked with construction oversight of the project told regulators.

In revealing testimony filed with the Georgia Public Service Commission’s (PSC’s) public interest advocacy staff on November 30, Donald Grace, vice president of engineering for Cost Plus Technology—Nuclear Construction Oversight (CPT), noted that the total construction cost—which includes all owner-shared costs but excludes financing costs—to complete the two Vogtle units by the scheduled November 2021/2022 timeframe is $ 17.1 billion. Only about 60% of the project is complete, he said.

Meanwhile, the project faces several potentially debilitating challenges that could cause delays and drive up costs. Foremost among them are labor shortages. While Georgia Power noted about 7,000 workers were onsite as of December 4, according to Grace, “Obtaining sufficient numbers of qualified craft labor pipe fitters and electricians are necessary to support the planned installation rate for bulk piping and electrical commodities.”…

In Energy Policy Pivot, France Will Shutter 14 Nuclear Reactors

France will shut down 14 of its 58 nuclear reactors by 2035 as well its remaining four coal power plants by 2022, French President Emmanuel Macron said November 27 in a lengthy speech that sought to clarify the country’s future energy direction.

According to the World Nuclear Association, France’s nuclear power share has steadily expanded since 1974, just after the first oil shock. However, France has pondered reducing nuclear’s share of its total generating mix from about 75% since 2012, when former President François Hollande ran on an election pledge to cut the nuclear share to 50% by 2025.

In 2014, the the lower house of France’s parliament passed the so-called “Energy Transition for Green Growth” bill, which set a nuclear cap at 63.2 GWe, which meant reducing nuclear’s share to 50% by 2025. In 2015, the Senate amended the bill to remove the 63.2-GW nuclear cap, but that same year, the National Assembly approved a new bill reinstating the cap.…

Voters Back Nuclear Power, Phaseout by 2025 Nixed

In a referendum held alongside local elections, the Taiwanese electorate voted overwhelmingly to abolish a stipulation in the country’s Electricity Act that called for all nuclear energy-based power-generating facilities to completely cease operations by 2025.

Many experts considered it a surprising victory for pro-nuclear activists. In January 2016, Taiwan’s Democratic Progressive Party garnered widespread support in elections, running on a platform that included the elimination of nuclear power by 2025. After the election, leaders quickly passed an amendment codifying the nuclear phaseout.

However, a blackout on August 15, 2017, apparently helped change many people’s views on nuclear power. The outage occurred when a contractor accidentally interrupted the gas supply to the 4,384-MW Tatan power station, Taiwan’s largest gas-fired plant. The interruption caused all six units at the site to shut down, and 6.6 million households and businesses across the island lost power for more than five hours. At the time, three of Taiwan’s six then-operational nuclear reactors were offline for maintenance.…
