Two More Japan Nuclear Units Will be Decommissioned

December 24, 2017

Kansai Electric Power Co. (KEPCO) announced it will permanently close two older nuclear reactors in Japan, rather than invest nearly 100 billion yen ($ 900 million) to bring the units up to the country’s new safety regulations. Japan’s Nuclear Regulation Authority (NRA) created new standards for the country’s nuclear plants after the meltdown at the Fukushima Daiichi plant in March 2011.

KEPCO on December 22 said it will decommission reactors No. 1 and No. 2 at the Oi facility in central Japan over the next year. Each unit has a generation capacity of 1,175 MW. The reactors, which came online in March 1979 and December 1979 respectively, will be the largest decommissioned in the country since the Fukushima disaster, which occurred when a 9.0-magnitude earthquake caused a massive tsunami that flooded the Fukushima plant in the northeastern part of the country. The resulting release of radiation was the largest since the Chernobyl meltdown in Russia in 1986.

Japan idled all 50 of its remaining nuclear units after the Fukushima incident.…

Moving toward sustainable manufacture of photovoltaics, Dr. Manuela Schiek’s research group in Oldenburg, Germany, has discovered how the latest technology in confocal laser scanning microscopy is enhancing both accuracy and efficiency of their research into organic semiconductors and transparent electrodes.

Harvesting energy directly from the sun in order to generate electricity, solar cells appear to represent the epitome of green energy. But have you ever stopped to consider the manufacturing process?

Take the case of crystalline silicon for example, a main component of conventional solar cells. First, transforming silica ore into its valuable crystallised form requires temperatures above 2,000C. Not only is this an incredibly energy-hungry process, but obtaining ultra-pure silicon also involves several hazardous chemicals and a potent greenhouse gas. Other main offenders in the modern manufacture of many inorganic thin-film solar cells include components comprising the toxic elements selenium and cadmium.

Indium is also a vital ingredient, forming indium tin oxide (ITO), but reserves of this finite resource are estimated to become unviable in the near future, which poses another set of potential challenges.…

Fires and explosions have caused a significant number of deaths and injuries to power plant staff over the years. To reduce hazards, protective measures must be considered during engineering, design, construction, and operation of power plants, particularly in electrical areas that are often a source of ignition. This quiz is designed to test your knowledge of electrical area classification.

Clean Coal Test Project Set for Wyoming

A test plant that will be part of research into producing cleaner-burning coal for power plants is set to begin operation next year in Wyoming, with the company behind the project saying global demand for coal makes the project viable even as the U.S. reduces its reliance on coal for electricity production.

Clean Coal Technologies Inc. (CCTI) is building the test facility in Tulsa, Oklahoma, and plans to move it to northeast Wyoming near the end of January 2018. The New York-based company has been developing what it calls “the world’s first commercially viable and scalable coal dehydration technology,” designed to upgrade the Btu content of lower-ranking coal “through the extraction of volatile material in liquid form,” ultimately producing a “cleaner burning, dry coal.”

The facility would dry Powder River Basin (PRB) coal, making it burn hotter with lower emissions, and increasing its value on the global market, according to CCTI. The company did not immediately respond to requests from POWER for comment on the cost of building and transporting the plant, although the company in June 2017 said a group of investors was seeking $ 80 million to build a facility in the PRB.…

Oman Starts Power Plant as Part of New Energy Development

Oman recently began operating a Wärtsilä-built power plant in the northern part of the country, part of more than $ 1 billion in power and energy projects being developed in the Arab nation. The Musandam Independent Power Project (IPP) is a 120-MW natural gas-fired plant (Figure 1) that can use light fuel oil as a secondary fuel. It is the first plant to be inaugurated as part of the Musandam Power Company (MPC), a consortium of Oman Oil Company (OOC)—which holds 70% of MPC shares—and LG International Corporation, a South Korean energy supplier and developer. The MPC was created to encourage energy-related development in Oman through both foreign and domestic investment.

Salim Al Hashmi, project director for MPC, at a mid-November ceremony officially opening the IPP said “This plant is a central part of the major integrated development of the Musandam Governorate. The project will play a significant role in meeting the power needs of the region’s current and upcoming industries, while at the same time benefiting the local community.”…
