Neutronics calculation of the conceptual TRISO duplex fuel rod design

open access: yesNuclear Materials and Energy, 2021
The duplex fuel pellet includes UO2 components as seed and ThO2 blanket, originally designed to increase the breeding rate of fissile materials in light water breeder reactors. However, the seed portion alone concentrates most of the energy released from

Assessment of TMSR-500 Shutdown Capability

open access: yesAtom Indonesia, 2022
The molten salt reactor (MSR) is a generation IV reactor with liquid fuel having nearly zero excess reactivity. Due to the very low excess reactivity, it requires a small number of control rods worth to shut down the reactor.

HTGR fuel rod deconsolidation [PDF]

open access: yes, 1978
High-Temperature Gas-Cooled Reactor fuel particles are bonded into rods by a carbonaceous matrix. In conjunction with the development of a system to determine fuel failure fractions from gamma analysis of individual particles, a technique was developed to separate the particles from the matrix after irradiation.
