Conceptual design study of the low power and LEU medical reactor for BNCT using in-tank fission converter to increase epithermal flux
A preliminary design of LPMR with unique FC facility, for increasing epithermal flux, similar
to a MNSR core is investigated. The U 3 Si 2-Al fuel with enrichment of 18.75% is optimized
as LEU fuel. Important neutronics parameters are calculated to investigate safety of the
LPMR. The optimization of the FC and BSA are performed. Presence of 34 FC rods increase
epithermal flux by 22.14%. The beam parameters are ϕ epi= 1.01× 10 9 n. cm− 2. s− 1, φ
th/φ epi= 0.033, D˙ fn/φ epi= 1. 83× 10-13 (G y. cm 2/n) and D˙ γ/φ epi= 1. 47× 10-13 (G y …
