ABSTRACT:
To measure the dimensional characteristics of elongated flow channels for nuclear fuel rod assemblies at the manufacturing site, an upender is utilized to swing a flow channel from a horizontal loading orientation to an upright pre-measurement position and then to shift the flow channel laterally into a measurement position where it is engaged and held by reciprocatingly mounted upper and lower endplugs while its dimensional characteristics are acquired by a measurement carrige mounted for vertical scanning movement along the entire flow channel length.
