ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

Metz on Harold Denton: Memories of a life in nuclear safety
A number of years ago, historian and writer Chuck Metz Jr. was at the Bush’s Visitor Center in Tennessee’s Great Smoky Mountains when he ran into former Nuclear Regulatory Commission official Harold Denton and his wife. Metz was at the visitor center, which opened in 2010 and is now a tourist hotspot, because, as he explained to the Dentons at the time, he had overseen the development of its on-site museum and had written a companion coffee-table history book.
The chance meeting turned into a friendship and a fruitful collaboration. Denton, who in 1979 was the public spokesperson for the NRC as the Three Mile Island-2 accident unfolded, had been working on his memoir, but he was stuck. He asked Metz for help with the organization and compilation of his notes. “I was about to retire,” Metz said, “but I thought that exploring the nuclear world might be an interesting change of pace.”
Denton passed away in 2017, but by then Metz had spent many hours with his fast friend and was able to complete the memoir, Three Mile Island and Beyond: Memories of a Life in Nuclear Safety, which was published recently by ANS. Metz shared some of his thoughts about Denton and the book with Nuclear News. The interview was conducted by NN’s David Strutz.

The JSFR is a commercial sodium-cooled fast reactor that has been studied in the Fast Reactor Cycle Technology Development (FaCT) project since 2006. For JSFR fuel handling, various fuel-handling systems (FHSs) were investigated, and an advanced FHS with an ex-vessel storage tank (EVST) was selected. This paper summarizes the various FHS concepts and comparisons among those concepts. In the reference system, spent-fuel subassemblies are cooled in the EVST before transfer to the spent-fuel storage pool. The other FHS concepts investigated are evolutional FHSs without an EVST. The result has indicated that the construction cost of the evolutional systems does not reduce the construction cost dramatically, which is mainly due to additional safety measures that required higher decay heat handling in a gas atmosphere and separated fresh and failed fuel storage. From an economics point of view, a longer plant outage of the evolutional systems offsets its advantage of the lower construction cost. Based on the results of this comparative study, JSFR selected the FHS with an EVST.
