摘要

Packed pebble beds are currently being considered in the design of 4th generation very high temperature reactors (VHTR). The VHTR design aims to provide enhanced safety due to low power density and larger thermal inertia as compared to light water reactors (LWR). Due to their higher operating temperatures, they also have higher thermal efficiencies and may be utilized for process heat applications.
