“…30 The HSD is described here in terms of CFPs in a matrix, but the concept is quite general and applicable to more diverse systems such as fully ceramic microencapsulated fuels and dispersion fuels. 31,32 The HSD is based on the notion of splitting a heterogeneous heat source � q into a spatial average � q h i and a fluctuation � q:…”

“…For the conversion of test reactors from High Enriched Uranium (HEU) to Low Enriched Uranium (LEU), either the fuel loading or fissile atom density must be increased to retain the same reactor performance. As the size of the reactors are typically fixed, high fissile density dispersion fuels consisting of U 3 Si 2 or UMo particles in an aluminum matrix have been used [52,53]. Fast reactor fuel consisting of metallic-coated fissile kernels surrounded by a "matrix" of fuel powder has also been proposed [54].…”

“…Porém, dada a baixíssima solubilidade dos gases de fissão como Xe e Kr nessa liga, esse combustível tende a apresentar significativo inchamento, o que pode comprometer a estrutura do combustível 46 . Além disso, testes de irradiação sugerem que o crescimento da camada de interação com a matriz de alumínio é considerável, podendo provocar não só a redução da espessura do revestimento, mas também descolamento e consequente inchamento, comprometendo a condutividade térmica do EC 47 . Esse problema vem sendo contornado com a adição de silício ao revestimento de alumínio 43 .…”
