Abstract
Void distribution measurements were performed to clarify the void behaviour phenomena in a rod bundle with a nonuniform rod gap. An X-ray computed tomography scanner was applied for the void distribution measurement in the rod bundle. The test results show that the void concentrates on the wider subchannel due to void drift and the void distribution becomes flatter with increasing quality. The vapour velocity at the wide subchannel becomes larger and the slip ratio between vapour and liquid increases compared with a uniform rod gap. Therefore, the average void fraction of the bundle is reduced.
