Facility Details: PITEAS

Organization / Localization: ASNR
Country: France
Facility Description: vol 3 m3 - 3 bar pressure, 120° C and up to 100 % relative humidity
Test Identification: PCON 01, PCON 02; PCON 03, PCON 04, PCON 05
SA-Related Topics / Phenomena: Several series of essentially separate effects tests are underway in the PITEAS facility to investigate condensation onto walls (diffusiophoresis) and onto hygroscopic aerosols (CsI)
Measured Parameters: T, P, RH, steam and CsI mass flow rates, aerosol mass concentration, aerosol size distribution, diffusiophoresis deposition rates and settiling deposition
Modelling: Mass concentration of suspended particles
Simulation Code: ASTEC AEROSOL-B2 (ESCADRE)
Experimental Research Program: Aerosol physics in containment project (FI4SCT950016) within the EU funded 4th framework programme Nuclear Fission Safety 1994-1998
Link to PIRT: ST-13, ST-14 and ST-15
