Latest Developments of Upgrading Tamper-Indicating Device Systems at Rosatom Enterprises

A tamper-indicating device (TID), used in conjunction with appropriate procedures for control, accounting, and surveillance, is a tool used to inhibit a insider from diverting nuclear material to unauthorized individuals. Most of the TIDs used at Rosatom nuclear facilities consist of seals that are not uniquely identified by number or bar code. The Russian Federal Atomic Energy Agency (Rosatom) and the US Department of Energy/National Nuclear Security Administration (US DOE/NNSA) have jointly agreed upon an upgrade strategy of TID systems for purposes of material control and accounting (MC&A) at Rosatom nuclear material facilities. A US-Russian TID working group was formed in order to facilitate the development of a jointly agreed upon plan and recommendations to implement modern TID systems at Rosatom sites. This paper will present the results of a series of activities that have been completed in the past year including the testing of TIDs available in Russia, developing practical methodological guidelines and recommendations for TID systems at Rosatom facilities, and evaluating the transition and sustainability impacts in upgrading TID systems at Rosatom sites.
