Newly-Appointed Minister Wants To Scrap N-power

Japan’s newly-appointed environment minister, Shinjiro Koizumi has said he wants to “scrap” nuclear power (N-power) plants, cautioning of the need to avoid a repeat of the 2011 Fukushima nuclear disaster, Concise News reports.

The comments from Koizumi, a rising political star and son of former Prime Minister Junichiro Koizumi, are his first on the controversial issue since he was named in a cabinet reshuffle Wednesday.

Speaking late Wednesday night, he appeared to echo his father’s post-Fukushima anti-nuclear stance.

“I would like to think about how we can scrap it, not how to retain it,” he told reporters when asked about the government’s plans for nuclear power.

“We’ll be finished if we let [a nuclear accident] occur twice in one country. We never know when we’ll have an earthquake,” he added, without specifying further.

The comments are not expected to have any immediate impact on the government’s already-stated position of moving slowly away from dependence on nuclear energy, a task complicated by Japan’s considerable reliance on coal.

A darling of the Japanese media, Koizumi, 38 is the third-youngest minister appointed to the cabinet in Japan since the end of World War II.

Despite intense media spotlight, he has been coy about expressing his views on controversial issues, including the question of nuclear power.

His father is known for having shifted his own stance on nuclear power dramatically since exiting politics, to a position of strong opposition.

The government of Prime Minister Shinzo Abe has said it wants to move away from nuclear energy, but it anticipates relying on the sector heavily for years to come, particularly as it works to meet its obligations under the Paris climate accord to reduce carbon emissions.

Its most recent plan envisages nuclear power supplying around 20-22 percent of energy needs for the country as late as 2030.

Nuclear energy too slow, too expensive to save climate – report

In related news, Nuclear power is losing ground to renewables in terms of both cost and capacity as its reactors are increasingly seen as less economical and slower to reverse carbon emissions, an industry report said.

In mid-2019, new wind and solar generators competed efficiently against even existing nuclear power plants in cost terms, and grew generating capacity faster than any other power type, the annual World Nuclear Industry Status Report (WNISR) showed.

“Stabilizing the climate is urgent, nuclear power is slow,” said Mycle Schneider, lead author of the report.

“It meets no technical or operational need that low-carbon competitors cannot meet better, cheaper and faster.”

The report estimates that since 2009 the average construction time for reactors worldwide was just under 10 years, well above the estimate given by industry body the World Nuclear Association (WNA) of between 5 and 8.5 years.

The extra time that nuclear plants take to build has major implications for climate goals, as existing fossil-fueled plants continue to emit CO2 while awaiting substitution.

“To protect the climate, we must abate the most carbon at the least cost and in the least time,” Schneider said.

The WNA said in an emailed statement that studies have shown that nuclear energy has a proven track record in providing new generation faster than other low-carbon options, and added that in many countries nuclear generation provides on average more low-carbon power per year than solar or wind.

It said that reactor construction times can be as short as four years when several reactors are built in sequence.

Nuclear is also much more expensive, the WNISR report said.

The cost of generating solar power ranges from $36 to $44 per megawatt hour (MWh), the WNISR said, while onshore wind power comes in at $29–$56 per MWh. Nuclear energy costs between $112 and $189.

Over the past decade, the WNISR estimates levelized costs – which compare the total lifetime cost of building and running a plant to lifetime output – for utility-scale solar have dropped by 88% and for wind by 69%.

For nuclear, they have increased by 23%, it said.

Capital flows reflect that trend. In 2018, China invested $91 billion in renewables but just $6.5 billion in nuclear.

In the United States, renewable capacity is expected to grow by 45 GW in the next three years, while nuclear and coal are set to retire a net 24 GW.

China, still the world’s most aggressive nuclear builder, has added nearly 40 reactors to its grid over the last decade, but its nuclear output was still a third lower than its wind generation.

Although several new nuclear plants are under construction, no new project has started in China since 2016.

Global nuclear operating capacity has increased 3.4% in the past year to 370 gigawatts, a new historic maximum, but with renewable capacity growing quickly, the share of nuclear in the world’s gross power generation has stayed at just over 10%.

In the decade to 2030, 188 new reactors would have to be connected to the grid to maintain the status quo, which is more than three times the rate achieved over the past decade, the WNISR estimates.

In May, the International Energy Agency warned that a steep decline in nuclear capacity will threaten climate goals, as advanced economies could lose 25% of their nuclear capacity by 2025.
