IRRADIATION SURVEILLANCE SPECIMEN ASSEMBLY

摘要

Case 4202 IRRADIATION SURVEILLANCE SPECIMEN ASSEMBLY A surveillance assembly within a nuclear reactor contains representative reactor material specimens which are to be irradiated. The material specimens are contained within sealed capsules that are stacked end to end within a holder tube. Each capsule is designed with shaped end fittings which intermesh with the adjacent end of an abutting capsule, holder tube end plug or holder tube closure device. The capsules are restrained by axial loading imparted by the closure device. The holder tube is orthotropically supported within the reactor.
