Survey to start for 1st new nuclear reactor since Fukushima disaster
Currently, the No. 3 unit is the only reactor in operation at the Mihama station in Tsuruga, Fukui Prefecture, while the other two units are set to be decommissioned.
No new reactor has been built in Japan since the building of the No. 3 unit at Hokkaido Electric Power Co.'s Tomari plant. The unit began operation in 2009.
"We will conduct (the survey) while explaining to and seeking the cooperation of local residents," Kansai Electric President Nozomu Mori said at a press conference in Osaka.
In 2010, Kansai Electric announced a plan to replace an aging reactor at the power station and started a survey, but the process was halted due to the nuclear disaster triggered by a massive earthquake and tsunami that devastated northeastern Japan the following year.
Public sentiment turned sour over the use of nuclear power as a national source of energy following the disaster, prompting the government to repeatedly say it was not considering building new reactors or replacing existing ones.
But with demand for electricity in Japan expected to increase in the future, the government and power industry have been discussing the need for a new or expanded facility to ensure a stable power supply.
The government signaled a return to nuclear energy in its revised basic energy plan released in February.
Due to strict safety standards introduced by the Nuclear Regulation Authority following the 2011 Fukushima disaster, the planned survey will likely begin from scratch. If the site is deemed suitable, Kansai Electric will need to draw up a basic design and submit it to regulators for approval before it can begin construction work.
The government is promoting the replacement of aging reactors with next-generation models that are deemed safer. Kansai Electric is collaborating with Mitsubishi Heavy Industries Ltd. and others to develop an advanced light-water reactor that is designed to be more resilient to natural disasters and terrorist attacks.

TEPCO posts huge loss for April-June over reactor decommissioning prep
Tokyo Electric Power Company Holdings has posted a huge loss for the April-June period, as it booked costs of preparing to decommission the crippled Fukushima Daiichi nuclear plant. The firm said on Thursday that its net loss for the period came to over 857. 6billion yen, or roughly 5.7 billion dollars, in contrast to the same period last year when it recorded net income of 79.2 billion yen. The net loss is the firm's largest for the quarter since the massive 2011 earthquake that hit northeastern Japan, leading to meltdowns at the plant. The result comes as Tokyo Electric booked an extraordinary loss of about 954 billion yen, or roughly 6.3 billion dollars. Most of the loss, about 903 billion yen, is due to newly expected costs for preparatory work to remove fuel debris from reactor facilities. Tokyo Electric says the costs will cover confirming the state of fuel debris, demolishing structures that hamper the work and reducing radiation levels in and around the reactor buildings. The preparations are expected to continue for some 12 to 15 years. The firm also says that after full-scale debris retrieval starts, costs may rise even further. Meanwhile, the utility logged an operating profit of over 64 billion yen, or around 430 million dollars, for the quarter. That's up 2.9 percent year on year.

Hopes Rise for More Nuclear Power in Japan after Hokkaido Reactor Passes Safety Screening
The No. 3 reactor at the Tomari nuclear power plant in Hokkaido could be restarted as early as 2027 if local governments approve, according to Hokkaido Electric Power Co. (HEPCO). The company's reactor passed a safety screening on Wednesday. The restart would significantly expand the power supply and help meet the rapidly growing demand for electricity in Hokkaido, particularly from data centers and semiconductor factories. The question is whether this will lead to the rebooting of other nuclear power plants across the country. 'We need to make the most of decarbonized power sources so that we can achieve economic growth and decarbonize at the same time,' said Yutaka Fujii, chairman of the Hokkaido Economic Federation, on Wednesday. He had high praise for the Nuclear Regulation Authority's approval of the reactor's safety at the Tomari plant. 'This is also extremely important for ensuring there is a stable power supply,' he said. The Tomari Nos. 1-3 plants accounted for nearly 50% of HEPCO's power supply mix in fiscal 2010 before the 2011 Great East Japan Earthquake. Since the quake, Hokkaido has relied entirely on non-nuclear sources of power, and primarily on thermal power generation. However, the earthquake that hit southern Hokkaido in 2018 damaged thermal plants, leading to a massive power outage across nearly the entire prefecture and highlighting the difficulty of ensuring a stable energy supply. SoftBank Corp. is constructing the country's largest data center in the prefecture's city of Tomakomai, and hopes to get it up and running by fiscal 2026. In April, chipmaker Rapidus Corp. launched a pilot line at its advanced semiconductor plant in Chitose, and it projects a demand of 100,000 kilowatts for mass production, which could start in 2027. Nationwide, power demand by 2050 is expected to reach as much as 1.25 trillion kilowatt-hours, about 1.4 times more than before the COVID-19 pandemic. Even if the restart of nuclear power plants proceeds smoothly, there will still be a shortage of over 23 million kilowatt — equal to the output of 23 nuclear plants. Japan currently has 36 nuclear power plants, including those under construction but excluding the 24 that are set to be decommissioned. Of these, only 14 have resumed operations since the 2011 earthquake. The government, in its 7th Strategic Energy Plan, which was approved in February by the Cabinet, has said it would 'maximize the use of decarbonized power sources such as renewables and nuclear power.' Work to expand nuclear plants, which halted after the earthquake, has also seen a resurgence. Kansai Electric Power Co. announced on July 22 that it would resume topographical and geological surveys in Mihama, Fukui Prefecture, as part of its plan to build a new reactor to replace Unit 1 at its Mihama nuclear power station. Kyushu Electric Power Co. is considering whether to develop innovative, next-generation reactors.

Tomari plant's No.3 reactor in northern Japan passes screening for restart
A reactor of the Tomari nuclear power plant in northern Japan has passed regulatory screening, which is a prerequisite for its restart. The Tomari plant is located in Hokkaido Prefecture and operated by Hokkaido Electric Power Company. Japan's Nuclear Regulation Authority in April compiled a draft screening report on the plant's No.3 reactor under the new regulations drawn up after the 2011 Fukushima Daiichi nuclear accident. It then sought public opinions. At an NRA meeting on Wednesday, officials reported they received 143 opinions. One of them says a survey on active faults in the seabed may have been insufficient. The NRA concluded that safety measures by Hokkaido Electric are all satisfactory, and it unanimously approved the screening report. The Tomari No.3 unit is the 18th reactor that has passed the screening. It took a record 12 years for the reactor to clear the review since the utility applied for it. That is partly because of a survey on active faults under the plant's site. Hokkaido Electric will proceed with safety measures that meet the new regulations, including construction of seawalls. The company says it wants to restart the reactor as early as possible in 2027.
