Description
Summary:In-Vessel Retention (IVR) through External Reactor Vessel Cooling is a severe accident management measure that is power limiting to the Westinghouse AP1000 due to critical heat flux (CHF) at the outer surface of the vessel. Increasing CHF by altering the coolant would increase safety margin at current design power or allow for higher power. Modification to current design would not require significant changes to the containment and systems.
