Argonne’s METL gears up to test more sodium fast reactor components
Argonne National Laboratory has successfully swapped out an aging cold trap in the sodium test loop called METL (Mechanisms Engineering Test Loop), the Department of Energy announced April 23. The upgrade is the first of its kind in the United States in more than 30 years, according to the DOE, and will help test components and operations for the sodium-cooled fast reactors being developed now.

Cyber-physical systems consist of interconnected physical processes and computational re- sources. Because the physical world is connected to the cyber world, cyber-attacks can result in damage to the physical system. If an attacker could access control inputs and mask measure- ments, a cyber-attack could damage the system while remaining undetected by plant operators or control systems. By masking certain sets of measurements, an attacker may cause a portion of the state space to become unobservable, meaning that it is impossible to reconstruct those states. This is called an observability attack. A sequential game-theoretic approach is presented to analyze observability attacks. The sequential game consists of alternating defense and attack stages. In each defense stage, the de- fender's strategy set consists of reinforcing all possible combinations of system measurements. In each attack stage, the attacker's strategy set has two components: a reconnaissance component and a measurement-masking component. The attacker's and defender's payo s are quanti ed at the end of each defense-attack sequence using the responses of the observable and unobservable states. The observability attack game is analyzed for two defense-attack rounds for a nuclear balance of plant system. A mixed-strategy Nash equilibrium is identi ed.
