Prospects of electricity and heat-only SMRs in the Baltic Region
In the recent years, small modular reactors (SMRs) for power and heat generation have gained high interest due to promise of carbon-free generation, design flexibility, low cost, and high safety features. In this study, electricity and heat-only SMRs are modelled in the Estonian, Latvian and Lithuanian energy systems at 2030. The results indicate that heat-only installations could replace fossil-based district heating generation cost-effectively in the Estonian and Latvian capitals. Meanwhile, electricity SMRs in the Baltic region seem profitable only under high price assumptions
Consolidation of Tin Sulfide Chalcogels and Xerogels with and without Adsorbed Iodine
Tin sulfide (Sn<sub>2</sub>S<sub>3</sub>) chalcogels are one of
the most effective nonoxide aerogels evaluated to date for iodine
gas capture. This is attributed to the fact that the Sn within the
gel network has a strong affinity for chemisorption of iodine to form
SnI<sub>4</sub>. This study demonstrates an approach for consolidating
the raw and iodine-sorbed Sn<sub>2</sub>S<sub>3</sub> chalcogels into
a chalcogenide glass using GeS<sub>2</sub> as a glass-forming additive.
Adding GeS<sub>2</sub> to iodine-sorbed or iodine-free Sn<sub>2</sub>S<sub>3</sub> chalcogels provides better glass formation than Sn–S
or Sn–S–I alone, and the quantity of iodine measured
in the bulk glass of the consolidated iodine-sorbed Sn<sub>2</sub>S<sub>3</sub> chalcogel was at ∼45 mass%. Additional experiments
were conducted using microwave sintering and hot isostatic pressing
with iodine-sorbed Sn<sub>2</sub>S<sub>3</sub> xerogels to evaluate
alternative consolidation techniques
