Neutronic calculations have been performed to a fluidized bed nuclear reactor that uses advanced coated particles to improve its endurance against irradiation and high temperature. The calculation is intended to determine whether reactor characteristics have been significantly compromised. The characteristic of the reactor is assessed by investigating the change in criticality from packed bed condition to a full expansion of the particle bed. The particle used in this calculation was based on the standard TRISO fuel particle as being used in the HTR-10 reactor, and the use of advanced fuel particle was performed by replacing the SiC layer by a ZrC layer. A packed bed of 50 cm high was used in this research with an additional 20 ppm of boron in the side reflector. At packed condition, replacing SiC by ZrC in TRISO particles significantly decreases the criticality with a range of -336 ± 138 pcm to -2809 ± 99 pcm. Calculation on expanded bed shows similar behaviors, in which case the decrease in reactivity spans from -269 ± 101 pcm to -1286 ± 121 pcm. The use of standard TRISO particles and advanced coated particles might create positive reactivity coefficients for particular height of expanded beds. © 2006-2016 Asian Research Publishing Network (ARPN). |
