Status 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 barcode. The Russian Federal Atomic Energy Agency (Rosatom) and the US Department of Energy/National Nuclear Security Agency (US DOE/NNSA) have jointly agreed upon an upgrade strategy of TID systems for purposes of material protection control and accounting (MPC&A) at Rosatom nuclear material facilities. A US-Russian TID working group was formed and given the task of making 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 evaluation and selection of TIDs available in Russia; a review of legacy TID systems at principle Rosatom sites; and an implementation plan for upgrading their TID program and regulatory documents. Additionally, this paper will present on-going activities for testing TIDs, 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.
