Reliable carbon-free power for the world — michelle catts, senior vice president, nuclear programs, ge-hitachi nuclear energy.

Michelle Catts is the Senior Vice President of Nuclear Programs at GE-Hitachi (GEH — https://nuclear.gepower.com/) located in Wilmington, NC.

Ms. Catts has over 18 years of demonstrated managerial and technical expertise in nuclear Regulatory Affairs and currently is responsible for ensuring world-class Quality, Continuous Improvement, Regulatory Affairs, and oversight of Environment, Health & Safety programs. She manages a multimillion-dollar budget and over a 30-member organization. She provides licensing and quality leadership and guidance to support nuclear fuel facility licensing, current nuclear fleet fuel reload/outage licensing activities, new reactor and new fuel opportunities, Technical Regulations and Standards, and GE-Hitachis’s Vallecitos and Morris sites.

The industry is gaining ground in understanding how aging affects reliability, but more variables make it harder to fix.

Circuit aging is emerging as a first-order design challenge as engineering teams look for new ways to improve reliability and ensure the functionality of chips throughout their expected lifetimes.

The need for reliability is obvious in data centers and automobiles, where a chip failure could result in downtime or injury. It also is increasingly important in mobile and consumer electronics, which are being used for applications such as in-home health monitoring or for navigation, and where the cost of the devices has been steadily rising. But aging also needs to be assessed in the context of variation models from the foundries, different use cases that may stress various components in different ways, and different power and thermal profiles, all of which makes it harder to accurately predict how a chip will behave over time.

The sensor sends out its location as it moves through the GI tract, revealing where slowdowns in digestion may occur.

Engineers at MIT

MIT is an acronym for the Massachusetts Institute of Technology. It is a prestigious private research university in Cambridge, Massachusetts that was founded in 1861. It is organized into five Schools: architecture and planning; engineering; humanities, arts, and social sciences; management; and science. MIT’s impact includes many scientific breakthroughs and technological advances. Their stated goal is to make a better world through education, research, and innovation.

We humans have a wonderful ability to keep developing, innovating, and engineering bigger, better, and faster contraptions. Close to Earth, we’ve been soaring through the skies in airplanes since 1903 thanks to the Wright brothers, and we’ve been launching spacecraft into space since 1957 when the Soviet Union rocketed the Sputnik satellite above our heads.

The team discovered a way of stabilizing detonation for hypersonic propulsion by creating a hypersonic reaction chamber for jet propulsions.

In a historic achievement, University of Rochester researchers have created a superconducting material at both a temperature and pressure low enough for practical applications.

“With this material, the dawn of ambient superconductivity and applied technologies has arrived,” according to a team led by Ranga Dias, an assistant professor of mechanical engineering and physics. In a paper in Nature, the researchers describe a nitrogen-doped lutetium hydride (NDLH) that exhibits superconductivity at 69 degrees Fahrenheit (20.5 degrees Celsius) and 10 kilobars (145,000 pounds per square inch, or psi) of pressure.

Although 145,000 psi might still seem extraordinarily high (pressure at sea level is about 15 psi), strain engineering techniques routinely used in chip manufacturing, for example, incorporate materials held together by internal chemical pressures that are even higher.
