TL;DR: In this paper, the H(15N, αγ)12C and D(3He, P) α reactions were used to measure H and D profiles in Zr-2.5 wt% Nb alloys and single crystals of Zr, which were oxidized in different atmospheres after loading with standard amounts of HO and D. Although considerable sample to sample variability was found, large H or D peaks were observed in the majority of the specimens, whose position corresponded to enhanced HO or D levels immediately below the surface oxide film.

TL;DR: In this article, the authors developed a mathematical model and carried out numerical simulation of one-dimensional heat conduction with phase change in a nuclear fuel rod including two regions: uranium dioxide fuel pellet and zirconium alloy cladding.

TL;DR: In this paper, a modified elastoplastic self-consistent model was used to simulate the texture and internal stresses developments of Zr alloy tubes processed via cold pilgering, and the contribution and the magnitude of the first- and second-order residual stresses were correctly evaluated using information from the model.

TL;DR: In this paper, the authors used transmission electron microscopy (TEM) to obtain evidence for vacancy precipitation in quenched and aged Zr-Al alloys and Zircaloy-2.

TL;DR: In this paper, a pulsed action of an electron beam on a Zr-1% Nb zirconium alloy was studied, where the surface layer of the alloy was modified without changing the structure phase state of its volume.
Abstract: A pulsed action of an electron beam on a Zr-1% Nb zirconium alloy is studied. Alloy samples are irradiated by three 50-μs pulses at an energy density of 15–25 J/cm2, a power of (3–6) × 104 W/cm2, a current density of 10–50 A/cm2, and an electron energy of 18 keV. This method of processing is found to modify the surface layer of the alloy without changing the structure-phase state of its volume. This surface modification increases the hydrogen saturation resistance of the alloy.
