“Existing NPPs to Enter Age of 80-Year Operations” JAIF Annual Survey Says

Each year, the Japan Atomic Industrial Forum, Inc. (JAIF) presents a survey titled “World Nuclear Power Plants.” This year's survey is compiled from data as of January 1, 2020 based on replies to questionnaires sent to electric power companies and nuclear-related organizations around the world.

Total Nuclear Capacity of Operating NPPs Decreases for First Time in 6 Years As of January 1, 2020, there were 437 operating nuclear power plants (NPPs) around the world, with a total generating capacity of 411,924 MW. Total nuclear capacity, which had been increasing since 2013, decreased for the first time in six years. Six had outputs less than 1,000 MW (total generating capacity of 4,300 MW) and had been operated for more than 40 years (since the 1970s): two in the U.S. and one each in South Korea, Sweden, Switzerland and Taiwan. The other six closed units totaling 6,430 MW of generating capacity had begun commercial operations in the 1980s and been operated less than 40 years: five in Japan and one in Germany. Existing NPPs to Enter Age of 80-Year Operations In the U.S., where e...more

Toshiba ESS and Yokohama National University Boost Joint Research to Upgrade Heavy-Ion Cancer Therapy, Using Kanagawa Prefectural Facility

Three Japanese institutions—Toshiba Energy Systems & Solutions Corporation (Toshiba ESS), Yokohama National University (YNU) and the Kanagawa Prefectural Hospital Organization—will accelerate joint research toward the upgrade of apparatus using heavy particle beams for cancer therapy.

For several years, Toshiba ESS has worked closely with Japan’s National Institute of Radiological Science (NIRS), a pioneer in heavy-beam cancer therapy, and now a division of the National Institute for Quantum and Radiological Science and Technology (QST). Committing itself to R&D on cancer treatment systems, the firm applied its superconductive electromagnetic technology to the rotating gantries of existing systems, which enable irradiation from all directions, allowing them to be made smaller and lighter. Treatment began in 2015 at the Ion-Beam Radiation Oncology Center in Kanagawa (i-ROCK), located within the Kanagawa Cancer Center of the Kanagawa Prefectural Hospital Organization. It is the fifth such facility built in Japan. According to information released by the three pa...more

NRA Grants Permission to Make Changes to Reactor Installation at HTTR under New Regulatory Standards

At a meeting on June 3, the Nuclear Regulation Authority of Japan (NRA) finalized a review report for the High-Temperature Engineering Test Reactor (HTTR), owned by the Japan Atomic Energy Agency (JAEA), saying that it was compatible with the new regulatory standards. The reactor, with a thermal output of 30MW, is situated in Oarai Town, Ibaraki Prefecture. The NRA then issued the Agency its approval to make changes to the reactor installation (basic design approval).

Earlier this year, on March 25, the NRA had issued a draft review report—which was also given to the Japan Atomic Energy Commission (JAEC) and the head of the Ministry of Education, Culture, Sports, Science and Technology (MEXT)—and made it open to the public for comments. It has been five and a half years since JAEA initially filed an application for an examination in November 2014. The HTTR is smaller than light water reactors (LWRs), which typically have electric outputs in the range of 1,000MW, but its outlet temperature of 850℃ to 950℃ at design thermal output—compared with just 300℃ for LWRs—is expected to be used for a broad range of purposes, including hydrogen production, the desalination of seawater, and regional power generation. Moreover, through its use of chemically sta...more

Sendai-2 Starts Periodic Inspection, with Due Date Imminent to Install Specific Safety Facilities

Since March of this year, a periodic inspection has been underway at the Sendai-1 (PWR, 890 MW), owned and operated by the Kyushu Electric Power Co.. On May 20, the company began a similar inspection of its Sendai-2 (PWR, 890 MW), the period for which was moved up because of the approaching deadline for the installation of facilities—termed specific safety facilities—to respond to specific severe accidents, including terrorist attacks, and which are mandated under the new regulatory standards for Japan’s nuclear power plants (NPPs).

Five-year grace periods for the installation of such facilities were granted from the date of approval of both plants’ construction work plans (detailed design approvals)—March 18 and May 22, 2015, for Sendai-1 and -2, respectively—so the deadline for Sendai-2 will expire soon. The two units had already cleared their examinations under the new regulatory standards ahead of others nationwide, having resumed operation in August and October 2015, respectively. The periodic inspection of Sendai-2 is expected to take approximately nine months, ending next year. In addition to work to install the specific safety facilities, refueling of the unit will also take place, as well as the installation of a permanent direct-current power supply system (the third one), as required under the new regula...more
