Metz on Harold Denton: Memories of a life in nuclear safety
Metz
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 molten salt waste from a pryochemical process to recover uranium and transuranic elements is one of the problematic radioactive wastes to be solidified into a durable waste form for its final disposal. This paper suggests a new method as a dechlorination approach to the immobilization of salt waste. The inorganic composite consists of SiO2, Al2O3, and P2O5 (SAP), which can generate a series of reactive sites for metal chlorides when in contact with molten salt. Under an oxidative condition, metal chlorides were successfully dechlorinated and converted into metal aluminosilicate, metal aluminophosphate, and metal orthophosphate, which are manageable at a high temperature. The optimum mixing ratio of SAP/salt in weight is about 2, and a borosilicate glass shows good compatibility with the reaction products containing phosphate compounds. By using a glass, a highly monolithic waste form was successfully fabricated at 1100°C, and more than 33 wt% of mixing ratio of glass as a chemical binder increased the chemical durability of the waste form. Use of SAP as an effective stabilizer can offer a chance to avoid Cl-induced problems and control the vaporization of volatile elements. This allows a high degree of freedom in the fabrication of monolithic waste form.
