ANS joins others in seeking to discuss SNF/HLW impasse
The American Nuclear Society joined seven other organizations to send a letter to Energy Secretary Christopher Wright on July 8, asking to meet with him to discuss “the restoration of a highly functioning program to meet DOE’s legal responsibility to manage and dispose of the nation’s commercial and legacy defense spent nuclear fuel (SNF) and high-level radioactive waste (HLW).”

A secure long-distance monitoring scheme is proposed for nuclear engineering applications using chaos synchronization and nonlinear observers for online transmittal of operational data, distance monitoring, fault detection, and other related processes. The proposed system consists of three components: (a) chaotic transmitter to encrypt and send signals coming from a message originating system, (b) chaotic receiver to decrypt information signals, and (c) reconstruction of the message originating system using the decrypted signals. The Lorenz chaotic system whose parameters are defined as nonlinear functions of the state variables to improve the security level of the chaos-based communication is considered as the chaotic encrypter. In the receiver section, a nonlinear observer is used to provide synchronization and to decrypt the message signal. A similar nonlinear observer is employed to reconstruct the message originating system state variables from the recovered message signal. Numerical results and case studies against certain passive eavesdropping attacks are provided to demonstrate the resilience of the proposed method. A reduced-order boiling water reactor model is used as the message originating system in the illustrations.
