• It is important from the viewpoint of reactor safety as well as from economical interest to determine the limit of allowable depth and length of surface defects on fuel cladding tubes. For the purpose of preparing cladding tubes provided with artificial defects of various degrees to be used as standard reference specimens for internal pressure burst tests, an apparatus has been developed for plowing troughs of predetermined depth and length on the inside surface of cladding tubes.<BR>This apparatus is capable of cutting such troughs in the center of a cladding tube 100 cm long, and the depth of the scratched defect can be measured nondestructively with the use of a measuring instrument provided with stylus.<BR>The paper presents an outline of the apparatus together with some experimental results.
