Confinement of airborne radioactivity. Progress report, January--June 1972.

Abstract

Radiolytic desorption tests of a series of carbon samples containing KI 3 , KI, triethylenediamine (TEDA), or combinations of TEDA and KI showed that a 10 x 16 mesh coconut shell carbon containing 1% TEDA, 2% KI,and a proprietary flame retardant retained iodine better than all products tested except those containing higher TEDA concentrations.Ignition temperature measurements on the same series of samples showed that the 1% TEDA -2% KI product has an ignition temperature of about 330°C under SRP flow conditions (the same as the KI3 carbon). The 1% TEDA -2% KI carbon has been selected to replace the unimpregnated carbon currently used in the Savannah River reactor confinement system.-2 - CONTENTS

Predictability of the 2020 Antarctic strong vortex event and the role of ozone forcing

“…However, it does not do inline ozone assimilation (Hersbach et al, 2020). The rainfall forecasts over Australia are verified against the BoM's Australian Gridded Climate Data (AGCD; Jones et al 2009;Evans et al 2020).…”

CONFINEMENT OF AIRBORNE RADIOACTIVITY. Progress Report, July--December 1971.

“…Previous data indicated that with one reactor room exhaust header open, only two compartments received 95% of the reactor room flow. 11 Filter pluggage test data were evaluated assuming different numbers of compartments on line and either equal distribution of steam-air-iodine flow to all compartments or steam-air-iodine flow through only two of the on-line compartments.…”
