Proc. ASME. ICONE29, Volume 11: Mitigation Strategies for Beyond Design Basis Events, V011T11A015, August 8–12, 2022
Paper No: ICONE29-92561
... the possibility to develop a pool scrubbing measure to retain graphite dust and fission products for the overpressure discharge of HTGR. A scrubber is set up with aerosol particle concentration measurement at both the inlet and outlet, which enables us to determine the decontamination factor (DF). By conducting...

Proc. ASME. ICONE29, Volume 15: Student Paper Competition, V015T16A079, August 8–12, 2022
Paper No: ICONE29-92120
... Abstract Aerosol is one of the main forms of fission products in nuclear reactor accidents, which are derived from direct leakage of solid fission products and homogeneous and heterogeneous nucleation of gaseous fission products. Pool scrubbing may reduce the leakage of radioactive aerosol...

Proc. ASME. ICONE29, Volume 15: Student Paper Competition, V015T16A025, August 8–12, 2022
Paper No: ICONE29-90448
... Abstract Pool scrubbing is one of the severe accidents (SA) countermeasures in nuclear power plants. In pool scrubbing, gas containing Fission Products (FPs) generated in the reactor during SA is passed through the pool water in the suppression chamber to move FPs into the pool water...
