Trial Operations of the Tamper-Indicating Devices at the Krasnoyarsk Electrochemical Plant

摘要

As a result of the U.S.–Russian Tamper Indicating Device (TID) Working Group’s accelerated efforts tofacilitate the modernization of TID programs at State Corporation Rosatom nuclear facilities, theElectrochemical Plant (ECP) was one of several sites selected at which to conduct a trial operation of anupgraded TID program. This paper discusses the joint Oak Ridge National Laboratory (ORNL) and ECPtrial operation activities in the area of material control and accounting system enhancement at ECP toensure safeguards with respect to highly enriched uranium (HEU) handling. The 6-month trial operationinvolved modernized TID design development, manufacture, and implementation at the HEU–lowenriched uranium (LEU) process. The TID is customized to ECP technical conditions of operation,including its application in the computer-based material control and accounting system. TID bar codingallows automation of all operations performed with TIDs, starting from its manufacture up to disposal.This paper describes the various stages and results of the TID trial operation and recommendations forapplication and design modification.
