EFFET ISOTOPIQUE DE L'HYDROGÈNE DANS L'IRRADIATION ET LA DÉCOMPOSITION THERMIQUE DU DIPHÉNYLE

摘要

The radiation stability and the thermal stability of ordinary (C12H10) and deutero (C12D10) diphenyl have been measured and compared. Deuterodiphenyl is more stable than the ordinary diphenyl by a factor of about 2, for pyrolysis at 460° C as well as for radiolysis at 30-40° C and at 310° C. This difference is of practical importance for the consideration of deutero-diphenyl as coolant for power reactors.
