Reactor reflector thickness
WebThe Li heat pipe can be replaced during long-term continuous reactor operation due to its high-temperature life limit (Rosenfeld et al., 2004; Choi et al., 2024). The 1,008 fuel elements are surrounded by the axial and radius reflectors to keep the criticality of the reactor. A shutdown/safety rod is located at the center of the reactor. WebThe paper is structured as follows: Section 2 contains the methane decomposition reactor system, which has a parabolic reflector, reactor, and catalyst. Section 3 explains the simulation methods for optical, ... owing to blocking that occurs from the pure structural thickness of the parabolic reflector and blind. In the calculation, an overall ...
