Maintaining RIPB in commercial LWRs
The new standard ANSI/ANS-30.3-2022, Light Water Reactor Risk-Informed, Performance-Based Design, has just been issued by the American Nuclear Society. Approved by the American National Standards Institute (ANSI) on July 21, 2022, the standard provides requirements for the incorporation of risk-informed, performance-based (RIPB) principles and methods into the nuclear safety design of commercial light water reactors. The process described in this standard establishes a minimum set of process requirements the designer must follow in order to meet the intent of this standard and appropriately combine deterministic, probabilistic, and performance-based methods during design development.

A new modification of the flow channel insert (FCI) called "double-layer" or "nested" FCI (nFCI) is assessed numerically for the poloidal duct flows in the dual-coolant lead-lithium (DCLL) blanket under the US DEMO outboard (OB) blanket conditions. The proposed nFCI mitigates the thermal stress while providing sufficient thermal insulation and reducing the MHD pressure drop.
