Control rod buffer seal shafts for the N.S. Savannah reactor are made of Armco 17-4 PH age-hardened stainless steel. The shafts used during the reactor startup testing program have been age hardened for at least four hours at 900 F. Replacement shafts are being manufactured and will be age hardened at 1100 F. This report describes the development of nondestructive tests both for 17-4 PH shafting during production and for finished shafts mounted in the reactor. The tests are sufficiently definitive to locate flaws and equivalent results are given by the laboratory and field tests. The development of nondestructive tests for both laboratory and field applications is outlined. Results from a series of experimental shafts tested by both test methods are compared and correlated with metallographic sections taken after completion of the nondestructive tests.
