Industrial Neutron Radiography in the United States

Abstract

This paper covers the neutron radiographic activities in the industrial community as experienced at Aerotest Operations over the last five years. A brief description of the Aerotest facilities, the neutron beam, the physical configuration and special capabilities are discussed. Several unique neutron radiographic applications are described, including a specific weld inspection of the vernier control engines for the space shuttle, the inspection of rubber diaphragms used to pressurize the fuel for operating engines under zero gravity conditions, the inspection of graphite phenolic blocks from which artificial hip joints are machined, and special fixture designs.
