NRC issues draft EA/FONSI for Duane Arnold restart
Efforts by NextEra Energy to restart the Duane Arnold nuclear power plant as early as 2029 continue to move forward with the Nuclear Regulatory Commission's preliminary environmental assessment and determination that the restart would have no significant environmental impacts.
On Thursday, the NRC posted a draft environmental assessment and a finding of no significant impact for the Palo, Iowa, facility; the Federal Register notice was published on Monday. The Department of Energy’s Office of Energy Dominance Financing is a cooperating agency on the draft EA, as the DOE is considering providing financial assistance to the restart project.

The p-c-T curves of D2 and T2 absorption by Ti and Zr were measured. there are one plateau at temperature below 300 °C and two plateaus at temperature range of 500~600 °C for Ti but one plateau below 525°C and two plateaus above 525°C for Zr. The thermodynamic parameters on different phases were determined and there are obvious thermodynamic isotope effects. The lag effect was not observed for Ti but its existent for Zr. The kinetic p-t curves of absorption were investigated at different temperature ranges and then the rate constants are calculated. The results show that the rate constants increase with raising temperature for Ti but decrease for Zr. The activation energy values are (110.2±3.0), (155.7±3.2) kJ.mol-1 respectively for Ti and (-25.9±0.7), (-6.8±0.8) kJ.mol-1 for Zr. The kinetic p-t curves of desorption were investigated too and the activation energy of desorption are (42.3±1.9), (62.1±1.6) kJ.mol-1 respectively for Ti and (40.1±0.8), (57.7±1.6) kJ.mol-1 for Zr. So there are remarkable kinetic isotope effects for Ti, Zr.
