Precision and perfection are the watchwords of today’s Space and Atomic Age. Nothing can be overlooked everything must be checked and rechecked before the “go” signal can be given. A crack in a missile’s fuel line, invisible to the human eye, can be disastrous. A defect in an atomic reactor, while not disastrous, can mean costly and time-consuming repairs. This program examines “non-destructive testing”, a new-comer, yet one of the most important engineering techniques. Non-destructive testing is simply a method of examining an object for defects without destroying it in the process. It is unlike other testing methods such as automobile test, for example, in which the vehicle is pushed to its maximum performance before it ends up on the junk pile. The television cameras are at the Metallurgy Division of the United States Atomic Energy Commission’s Argonne National Laboratory, where scientists are using such non-destructive testing techniques as X-rays, gamma rays, and neutron radiography. At Argonne, neutronradiography is an invaluable aid to pinpoint what happens to uranium or plutonium fuel that sustains a chain reaction in an atomic reactor. The knowledge gained through this technique is important in designing the atomic power plants of today and tomorrow. Also shown are the ultrasonic testing methods used to detect imperfections by “bouncing” sound waves through objects that are being tested. One of these methods converts sound waves into electronic signals to show television pictures of hidden defects. The value of these non-destructive testing methods becomes increasingly more important as the tolerances become smaller and smaller for the new atomic reactors, space vehicles, and aircraft engines that are being constructed.
