Abstract
Type B radioactive material package elastomeric O-rings have, historically, been replaced annually to satisfy inspection requirements of ANSI N14.51. The recently approved ANSI N14.5-20142 allows for an alternative inspection frequency with appropriate justification. This paper examines the available data, evaluates potential failure mechanisms, and recommends a reduced inspection frequency based on characteristics of transportation and storage environments.
