NUCLEAR WARModeling the Threat of Nuclear War

By Poornima Apte

It’s a question that occupies significant bandwidth in the world of nuclear arms security: Could hypersonic missiles, which fly at speeds of least five times the speed of sound, increase the likelihood of nuclear war?

Eli Sanchez, who recently completed his doctoral studies at MIT’s Department of Nuclear Science and Engineering (NSE), explored these harrowing but necessary questions under the guidance of Scott Kemp, associate professor at NSE and director of the MIT Laboratory for Nuclear Security and Policy.

A Well-Rounded Interest in Science
Growing up in the small railroad town of Smithville, Texas, Sanchez fell in love with basic science in high school. He can’t point to any one subject — calculus, anatomy, physiology — they were all endlessly fascinating. But physics was particularly appealing early on because you learned about abstract models and saw them play out in the real world, Sanchez says. “Even the smallest cellular functions playing out on a larger scale in your own body is cool,” he adds, explaining his love of physiology.

Attending college at the University of Texas in Dallas was even more rewarding, as he could soak in the sciences and feed an insatiable appetite. Electricity and magnetism drew Sanchez in, as did quantum mechanics. “The reality underlying quantum is so counterintuitive to what we expect that the subject was fascinating. It was really cool to learn these very new and sort of foreign rules,” Sanchez says.

Stoking his interest in science in his undergraduate years, Sanchez learned about nuclear engineering outside of the classroom, and was especially intrigued by its potential for mitigating climate change. A professor with a specialty in nuclear chemistry fueled this interest and it was through a class in radiation chemistry that Sanchez learned more about the field.

Graduating with a major in chemistry and a minor in physics, Sanchez married his love of science with another interest, computational modeling, when he pursued an internship at Oak Ridge National Laboratory. At Oak Ridge, Sanchez worked on irradiation studies on humans by using computational models of the human body.

Work on Nuclear Weapons Security at NSE
After Oak Ridge, Sanchez was pretty convinced he wanted to work on computational research in the nuclear field in some way. He appreciates that computational models, when done well, can yield accurate forecasts of the future. One can use models to predict failures in nuclear reactors, for example, and prevent them from happening.
