| Summary: | Hydride Microreactor has the potential to be deployed in Indonesia,
especially to meet electricity demand in remote areas. This is due to its small size
facilitates manufacturing and construction, and requires less footprint than larger
scale nuclear reactors. In terms of safety, microreactors are superior to large – scale
nuclear reactors. In this research, neutronic analysis was carried out for Hydride
Microreactor designed by Gadjah Mada University microreactor research team. The
proposed Hydride Microreactor design is in the eraly stages of development, and
research is needed to obtain the best fuel design.
In this research, the design of Hydride Microreactor was modeled and
simulated using Serpent 2 code. The neutronic variables analyzed in this research
were multiplication factor during reactor startup and operation, PPF, reactivity
coefficient, and reactor shutdown system capability during BOC. Independent
variables used in this research were enrichment and fuel pitch size. These variables
were analyzed for each changes in fuel pitch size and enrichment.
Considering the previously stated variables, the best fuel pitch size and
enrichment for Hydride Microreactor are 2,4 and 7%, respectively. This best design
yields PPF value of 2.0303 and has overall negative temperature reactivity
feedback. It also meets the shutdown system capability requirement as stated in
IAEA SSG – 52. |
