NRC proposes security regulation changes
In 2025, President Trump issued Executive Order 14300, “‘Ordering the Reform of the Nuclear Regulatory Commission,” which directs the NRC to conduct a sweeping, multifaceted overhaul of its structure, culture, and regulations with the aim of facilitating increased deployment of new nuclear technologies and capacity.

The stability of ZrNi and ZrCo to heat cycles in hydrogen atmosphere was studied through changes in absorption-desorption characteristics and in crystallo-graphic structures. ZrCo easily lost its absorption- desorption capacity of hydrogen below 30 heat cycles between room temperature and a given temperature in a range of 400 ∼600 °C. X-ray diffraction analysis showed that ZrCoH3 initially formed decomposed to ZrH2+ ZrCo2. On the other hand, ZrNi was more durable than ZrCo to the similar heat cycles. But, it was found that the absorption-desorption characteristics was degraded by heat cycles over 500. The X-ray analysis showed that ZrNi also dispropor-tionated to ZrH2 and ZrNi3. The difference in the stabilities between the two materials appears to be due to the difference in crystallographic nature upon formation of the respective hydrides.
