Fabrication milestone for INL’s MARVEL microreactor
A team from Idaho National Laboratory and the Department of Energy’s Office of Nuclear Energy (DOE-NE) recently visited Carolina Fabricators Inc. (CFI), in West Columbia, S.C., to launch the fabrication process for the primary coolant system of the MARVEL microreactor. Battelle Energy Alliance (BEA), which manages INL, awarded the CFI contract in January.

In nuclear power plants, instrument failures must be detected and compensated for before a significant decrease in plant performance occurs. The improved generalized likelihood ratio method to detect and identify a failure and a control algorithm in the event of an instrument failure is developed. The failure detection algorithm and the control algorithm are combined and applied to a pressurized water reactor pressurizer. Computer simulation tests show that on-line prompt failure detection and compensation through control action can be performed very successfully even when there is an instrument failure.
