High-temperature plumbing and advanced reactors
The use of nuclear fission power and its role in impacting climate change is hotly debated. Fission advocates argue that short-term solutions would involve the rapid deployment of Gen III+ nuclear reactors, like Vogtle-3 and -4, while long-term climate change impact would rely on the creation and implementation of Gen IV reactors, “inherently safe” reactors that use passive laws of physics and chemistry rather than active controls such as valves and pumps to operate safely. While Gen IV reactors vary in many ways, one thing unites nearly all of them: the use of exotic, high-temperature coolants. These fluids, like molten salts and liquid metals, can enable reactor engineers to design much safer nuclear reactors—ultimately because the boiling point of each fluid is extremely high. Fluids that remain liquid over large temperature ranges can provide good heat transfer through many demanding conditions, all with minimal pressurization. Although the most apparent use for these fluids is advanced fission power, they have the potential to be applied to other power generation sources such as fusion, thermal storage, solar, or high-temperature process heat.1–3

GE Hitachi Nuclear Energy
Jay Wileman was named President and CEO of GE Hitachi Nuclear Energy (GEH) in November 2015. In this role, he is responsible for leading the nuclear business with 3,000 employees and manufacturing, service and sales facilities around the globe. He is also responsible for managing the joint venture between the General Electric Corp. (NYSE: GE) and Hitachi Corp.
With more than 30 years’ experience, Jay has a wealth of international knowledge, having led many global teams to success across the energy spectrum. Prior to being named President and CEO of GEH, he served as Senior Vice President, Nuclear Plant Projects and Chief Operating Officer, a position he assumed in 2012.
From 2009-2012 Jay served as President of GE Energy Sub-Saharan Africa where he led a team that provided integrated product and service solutions that met the continent’s needs in oil, natural gas, power generation, water, renewables and new grid modernization.
Since joining GE in 1994, Jay has held positions in engineering, manufacturing, industrial services and financial services in the U.S., Japan, Italy, Australia and South Africa. He served for three years as GE’s Global Mining leader. Before that, Jay was President and CEO of GE Equipment Services – Rail Services, where he managed and led the business’ railcar and intermodal services and leasing fleet. He also served for four years as General Manager for Global Services for Oil and Gas in Florence, Italy where he led double-digit growth in customized service agreements.
Jay started his GE career with the company’s nuclear business where he spent more than eight years in progressively larger positions in engineering, manufacturing, business development and services. Jay was a nuclear fuel engineer and commercial manager for Southern Nuclear before he joined GE.
Jay earned a Bachelor of Science degree in Nuclear Engineering from Mississippi State University and a Master’s Degree in Business Administration from the University of Alabama at Birmingham.
