Nuclear Safety Analysis of a Molten Salt Breeder Reactor

analysis of nuclear safety demands further quantitative examination of the reactor system behavior, with calculations of fuel salt and graphite temperatures. The model adopted for these calculations will first be described in what follows. In an MSBR

Thermal Imaging Research Papers

Thermal images are easily visualized with good spatial and thermal resolutions (0.044 mm and 0.05 degrees C in our system). The focus and field structure such as side lobes can be identified in real time from the direct video output. 3D maps and image planes at arbitrary orientations to the beam axis can be obtained and reconstructed within a few minutes.

XRD and DTA Analysis of Developed Agglomerated

To know the effect of temperature over phase transformation and melting of different compounds, differential thermal analysis (DTA) was carried out from 1000 to 1400 ∘ C. This study aims to know the quantity of ions present (percentage) and melting behavior of developed agglomerated fluxes for submerged arc welding process.

Novel Synthesis and Thermal Behavior of Aluminum

A new synthesis route to nonhydrated, X-ray amorphous aluminum hydroxy fluorides was explored by sol−gel synthesis with aqueous hydrofluoric acid. Followed by XRD, MAS NMR, and DTA-TG, it can be shown that the product composition after thermal annealing critically depends on the gaseous atmosphere. Dependent on the fluorine content, corundum formation can occur at temperatures as
