Most of the liquid high-level nuclear waste (HLW) generated over the last 35 years has come from reprocessing of spent (used) nuclear fuel (SNF) from government-owned plutonium production reactors, as well as from naval, research, and test reactors. A small amount of liquid HLW was generated from the reprocessing of commercial power reactor fuel in the 1960s and early 1970s. This HLW produced from fuel reprocessing activities associated with research and defense purposes in the Cold War era is called legacy waste.
With the theme “BEYOND SMART,” SEMICON West 2018 will offer technical and business programming, networking opportunities, and an exhibition.
June 21, 2018
Business and technology leaders, researchers, and industry analysts from across the extended electronics supply chain will gather July 10-12 at the Moscone Center in San Francisco for SEMICON West 2018.
Line confocal sensors, and the scanners based on them, can be used in the imaging of shiny and mirror-like surfaces, transparent materials, and multi-layered structures in various metrology and inspection applications.
In the late 2000s, researchers at Technical Research Center of Finland (VTT) invented a new optical method to image 3D microtopography of surfaces at sub-micron resolution. This method, called line confocal imaging (LCI), is based on capturing a continuous line of light reflections in visible spectrum from more than 2,000 lateral surface points simultaneously.
Internal defects (usually described as cracks or voids) in the diamond inserts that make up the drill head used in drilling oil wells typically consist of some type of gap in the diamond material. The mechanical forces applied to a diamond insert are so great that these defects may cause the insert to fracture, even though it cannot be scratched by the rock layers it is drilling through.
It is thus worthwhile to identify the inserts having internal gap-type defects and remove those inserts from the assembly process. Some defects in the diamond can be seen optically, but those that do not reach the surface require a different approach to make them visible.
Measuring density is crucial for the manufacture of many of today’s products. Being able to characterize the structure and quality of solid materials quickly and efficiently can not only help guide development and manufacturing processes, it also influences the quality of the end products.
Attendees and exhibitors from around the world met at Ceramics Expo 2018, which was held May 1-3 in Cleveland, Ohio, to share new technologies and learn how advanced ceramics can help drive developments in a range of industries.
The manufacturing industry has always been an important foundation of the U.S. economy. From glass and ceramics that are critical to automotive, food, medical, construction, and electronics manufacturing to other discrete and process industries, manufacturing is vital. In fact, current research indicates that no other sector creates more economic value or supports more additional jobs than manufacturing.
Deco ’18 returned to the Hilton Easton in Columbus, Ohio, site of the 2015 show, for another successful gathering. Columbus falls within the radius of driving distance for many members, and the Easton area is an excellent backdrop for a conference, providing numerous dining and entertainment options for attendees.
According to the World Nuclear Association, around 440 nuclear power reactors provided approximately 11% of the electricity used worldwide in 2015, and an additional 160 reactors are in
the works today.
