The NRC’s Annie Caputo resigns
Caputo
Commissioner Annie Caputo is resigning from the Nuclear Regulatory Commission, according to a statement sent out to staff on Tuesday morning. Her resignation comes one day after the U.S. Senate voted to reconfirm chair David Wright to the commission.
“The time has come for me to more fully focus on my family,” Caputo said in her statement, provided by NRC spokesperson Scott Burnell. “I believe the [Trump] administration’s recent executive orders and the bipartisan ADVANCE Act have given the agency a platform for change.”

A tritium imaging plate technique (TIPT) was used to measure the hydrogen solubility and diffusivity of a proton-conducting material, Zr-doped BaInO2.5. After being exposured to tritiated water vapor, the specimen was cut into halves and photo-stimulated luminescence (PSL) images of the cross-section of the cut specimen were obtained. Based on the PSL distribution profiles and intensities, hydrogen diffusivity and solubility in the specimens were determined. The hydrogen solubility and diffusivity in Zr-doped BaInO2.5 clearly depended on the content of Zr. This characteristic of the Zr content is in agreement with the Zr-content dependency of its proton conductivity, which was measured by an alternating current (AC) impedance method.
