Atmospheric radiochemistry

Harteck did important work in quantum-and radiochemistry and also played a leading role in Germany s atomic energy program during World War II. See P. F. Dahl, Heavy Water and the Wartime Race for Nuclear Energy (Bristol, 1999). After the war, when Harteck settled in the United States, he focused on atmospheric and interstellar chemistry. See A. Farkas, Paul Harteck The triumphant decade 1925-1934, Am-bix 36 (1989) 91-102. 

The field of chemistry was benchmarked by an ad hoc panel of 13 members, 12 from the United States and one from Switzerland, with expertise across the 11 selected areas covered in the report, which are analytical, atmospheric, biological, chemical education, inorganic, macromolecules, materials and nanoscience, nuclear/radiochemistry, organic, physical, and theory/computation. The panel was charged with addressing three questions ... 

For the containment the objective is to study the fission product chemistry and especially iodine radiochemistry in the sump water and atmosphere and the effect of p ts in the "dirty" chemical conditions of a reactor accident. 

Tentative boundary conditions for the containment involve two successive phases. During the first one the containment has an atmosphere temperature around llO C, a humidity ratio near 60 % and with steam condensation onto the condenser surfaces. For good scaling of the volume to surface ratio, the vessel walls are rendered "neutral", as far as condensation is concerned. Condensation, aerosol diffusiophoresis and FP-paint interaction take place on suspended structures called "condenser". V/hen the bundle and circuit transient are over, the circuit is disconnected aerosol deposition and subsequent operation of a washing system transfer FPs to me sump water. This second period duration is 3 days with an atmosphere temperature increase up to 150°C and superheated conditions. This period is devoted to Iodine radiochemistry.
