Title

GEN IV Webinar - Passive Decay Heat Removal Systems, October 23, 2019 @ 8:30 AM

Body

A major design goal for Generation IV nuclear energy systems is to reduce or eliminate the likelihood and/or extent of reactor core damage incurred during an off-normal operating event, thereby eliminating the need for offsite emergency response. One approach for achieving this objective is to develop inherently safe reactor designs that can passively dissipate decay heat to the environment without relying on operator action during an event of this type. Historically, this approach has been taken for both sodium- and gas-cooled Generation IV reactor types by providing Reactor Cavity Cooling Systems (RCCS) that are designed to passively dissipate decay heat to the environment by natural convection while maintain fuel temperature below the threshold for onset of core damage. This presentation will begin by providing a high level overview of RCCS systems that have been developed for advanced reactor designs over the years. This will be followed by a summary of large scale integral effect tests that are currently underway at Argonne to provide licensingquality data for two of these systems; i.e., air- and water-cooled RCCS concepts. https://www.gen-4.org/gif/upload/docs/application/pdf/2019-09/dr_mitch_farmer_webinar_annoucement_-_final.pdf
