The Japanese Nuclear Regulatory Authority (NRA) approved Kyushu Electric Power Co.’s operational safety programs for Sendai Nuclear Power Station Units 1 and 2 on May 27. The approval is the last of three needed by the company to verify that the plant complies with new regulatory requirements implemented as a result of the Fukushima disaster. […]

NRC Advances Design Certification of Westinghouse SMR, South Korea’s APR1400. The Nuclear Regulatory Commission (NRC) on Feb. 27 approved Westinghouse Electric Co.’s testing approach for its small modular reactor (SMR) design—a “significant” step that the Toshiba Corp. company said will reduce the time ultimately needed to obtain design certification. By granting a safety evaluation report […]

A Japanese court has rejected a petition to halt the restart of two reactors at the Sendai nuclear power plant, putting the country on course again to revive its long-stalled nuclear power sector.  The Kagoshima district court in southwest Japan rejected claims by residents that nearby volcanoes pose risks to the Sendai plant, and that […]

A Japanese court has blocked plans to reopen two reactors that had been previously cleared to resume operations by the Nuclear Regulation Authority (NRA).  Local residents in western Japan’s Fukui Prefecture, where Kansai Electric Power Co.’s Takahama nuclear plant is located, successfully petitioned a court to issue an injunction halting plans to restart Units 3 […]

Four Japanese utilities last week announced that they would retire five older reactors rather than implement strict and expensive safety requirements mandated by new nuclear regulations.  Kansai Electric Power Co. on March 17 said it will close two reactors (340 MW and 500 MW) at its Mihama nuclear plant in Fukui Prefecture. On the same […]

Four years after the massive earthquake and ensuing tsunami heavily damaged the Fukushima Daiichi nuclear plant in Japan, cleanup efforts continue amid new challenges, while Japan has made little progress on the policy front. The Ongoing Crisis at Daiichi By the fourth anniversary of the devastating events at Fukushima, the situation onsite has improved markedly, […]

Kyushu Electric Power Co.’s twin Sendai nuclear units in Japan’s Kagoshima Prefecture on Nov. 7 got the government’s green light to restart. Once back online, likely in 2015, the units will be the first to restart of Japan’s 48 reactors that were shuttered for safety checks following the March 2011 Fukushima accident. Kagoshima Prefecture Governor Yuichiro […]

Bad weather, unforeseen setbacks, and even natural disasters are far from unheard of during power plant construction. But there may be no plant that experienced the sort of construction hardships that Tokyo

Mitsubishi Heavy Industries (MHI) in August revealed that it had developed a 2-MW 16-cylinder high-speed gas engine that potentially offers a power generation efficiency (lower heating value) of more than

Japan’s Nuclear Regulation Authority (NRA) has approved Kyushu Electric Power’s application to make changes to its Sendai reactors, putting them a step closer to resuming operations.  The regulatory agency this July said in a 400-page draft report that Kyushu’s No. 1 and No. 2 reactors at its Sendai plant in southern Japan’s Kagoshima prefecture passed […]

Fourteen members of the World Trade Organization (WTO)—including the U.S., China, the European Union (EU), and Japan—on Tuesday launched negotiations to eliminate tariffs or custom duties on wind turbines, solar products, and other environmental goods.  The first phase of negotiations between the 14 WTO members, which make up 86% of the global environmental goods trade, […]

In a stark departure from the zero-nuclear future proposed by a previous administration, the cabinet of Japan’s Prime Minister Shinzo Abe Friday endorsed restarting the country’s idled nuclear reactors as it develops more renewables.  The cabinet on Friday officially adopted the first Basic Energy Plan since the Fukushima disaster, a 78-page document (in Japanese) that […]

Japan and South Korea, countries that depended heavily on nuclear power before the Fukushima catastrophe in 2011 (Figure 3), separately released draft long-term energy plans in December, both placing renewed

In 2010, intent on continuing its commitment to energy efficiency and preventing climate change, Japan enacted its second Basic Energy Plan. The new policy document, revising the first, from 2003, called for

A prototype 100-kW floating wind turbine that has been tested off Nagasaki near Japan’s Kabashima Island since May 2012 is slated to be replaced by a full-scale, grid-connected 2-MW wind turbine this fall
