Subcriticality Measurement of Jackets with Spent FA VVER-1000 in a KhOT-1 Storage Facility Using the SKP-KhOT System

  • 2 Accesses

The SKP-KhOT system for measuring subcriticality, making it possible to determine Keff of jackets with spent FA VVER-1000 during normal operation as well as design basis and beyond-design basis accidents, has been installed in the KhOT-1 storage facility at the Mining and Chemical Combine. The results of its tests have been recognized as positive; the design basis subcriticality of the studied jackets falls within the confidence interval of the measured value. It is shown that Keff of a jacket does not depend on its environment.
