FLiBe is currently investigated for several advanced fusion and fission reactor concepts where tritium generation in the FLiBe is anticipated. Knowledge of hydrogen transport properties through Hastelloy N is important to understand how tritium would permeate through this material and result in an unintentional release. In this study, the hydrogen and deuterium permeability, diffusivity, and solubility were measured from 500 to 700 °C at a primary-side pressure of 10 kPa in a well-characterized sample of Hastelloy N. The prepared polycrystalline Hastelloy N had C and O impurities present on the surface. These impurities were investigated using Auger Emission Spectroscopy and Ar depth profiling. The adventitious C was removed upon the first Ar sputter cycle whereas O persisted deeper into the sample. For permeation experiments, applied deuterium pressures ranged from 13 Pa to 100 kPa and deuterium transport remained in the diffusion-limited regime (J ∝ P0.5) throughout the pressure range examined. Two methods are employed to measure the effective hydrogen and deuterium diffusivity: rise and decline. The decline method produced improved statistical model fits for calculating the effective diffusion coefficient compared to the rise method. The resultant transport properties compared well to published values for other nickel alloys.} +} \ No newline at end of file From 960e7e50ab6df369d95943becfa58db1890eaf76 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?R=C3=A9mi=20Delaporte-Mathurin?= <40028739+RemDelaporteMathurin@users.noreply.github.com> Date: Wed, 5 Jun 2024 10:18:41 +0200 Subject: [PATCH 2/2] correct indent --- h_transport_materials/property_database/hastelloy_n.py | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) diff --git a/h_transport_materials/property_database/hastelloy_n.py b/h_transport_materials/property_database/hastelloy_n.py index ba24362b..70151f70 100644 --- a/h_transport_materials/property_database/hastelloy_n.py +++ b/h_transport_materials/property_database/hastelloy_n.py @@ -120,11 +120,11 @@ zhang_solubility_h, zhang_solubility_d, fuerst_permeability_h, - fuerst_permeability_d, - fuerst_solubility_h, - fuerst_solubility_d, - fuerst_diffusivity_h, - fuerst_diffusivity_d, + fuerst_permeability_d, + fuerst_solubility_h, + fuerst_solubility_d, + fuerst_diffusivity_h, + fuerst_diffusivity_d, ] for prop in properties:
