A note on a core catcher of a cooperative game [PDF]

Zeitschrift für Operations Research, 1986
The author's former results concerning the core of a cooperative game are generalized. Namely, it is shown that the core is included in the convex hull of certain marginal imputations.

High-Temperature Characterization of Melted Nuclear Core Materials: Investigating Corium Properties Through the Case Studies of In-Vessel and Ex-Vessel Retention

Frontiers in Energy Research, 2022
During a severe accident in a nuclear reactor, the molten core—or corium—may be relocated into the reactor vessel’s lower plenum in case of core support plate failure.

Numerical Investigation of Corium Coolability in Core Catcher: Sensitivity to Modeling Parameters [PDF]

Volume 4: Nuclear Safety, Security, and Cyber Security; Computer Code Verification and Validation, 2018
To avoid settling of molten materials directly on the vessel wall in severe accident sequences, the implementation of a ‘core catcher’ device in the lower plenum of sodium fast reactor designs is considered. The device is to collect, retain and cool the debris, created when the corium falls down and accumulates in the core catcher, while interacting ...

Assessment of the MARS Code Using the Two-Phase Natural Circulation Experiments at a Core Catcher Test Facility

Science and Technology of Nuclear Installations, 2017
A core catcher has been developed to maintain the integrity of nuclear reactor containment from molten corium during a severe accident. It uses a two-phase natural circulation for cooling molten corium. Flow in a typical core catcher is unique because (i)

Isomer studies in the vicinity of the doubly-magic nucleus 100Sn: Observation of a new low-lying isomeric state in 97Ag

Physics Letters B, 2020
Long-lived isomeric states in 97Ag and 101−109In were investigated with the FRS Ion Catcher at GSI. In the isotope 97Ag, a long-lived (1/2−) isomeric state was discovered, and its excitation energy was determined to be 618(38) keV. This is simultaneously

Numerical Research on Relocation Behavior of Melt Debris Flow-in Sodium-cooled Fast Reactor

Yuanzineng kexue jishu, 2023
After core meltdown of the sodium-cooled fast reactor (SFR), the jet of molten corium interacts with liquid sodium, which is called molten fuel-coolant interaction (MFCI). The molten corium is fragmented and solidified.
