Using Frozen Beads from a Mixture of Mesitylene and Meta-Xylene with Rupert's Drop Properties in Cryogenic Neutron Moderators / M.Bulavin, I.L.Litvak. – Text: electronic // Journal of Nuclear Engineering. – 2025. – Vol. 6, No. 2. – P. 9. – URL: https://doi.org/10.3390/jne6020009. – Bibliogr.: 25.

An experimental study was conducted on the feasibility of using frozen beads with the properties of Rupert’s drops—solid frozen beads with enhanced strength made from a mixture of aromatic hydrocarbons—in cryogenic neutron moderators utilizing bead technology. It is demonstrated that the use of a new modification of the dosing device with a high discharge rate (approximately 6 units/s) significantly improves process efficiency. With standard pneumatic transport parameters maintained, it was possible to load solid frozen beads made from a mixture of mesitylene and meta-xylene into the cryogenic moderator chamber. The loading speed increased five-fold, while the beads remained intact during pneumatic transport.
