method for reprocessing of nuclear ammoniumnitrathaltigen abfalllösungen

摘要

up to the present invention is to optimize the spruehzersetzung after the hauptpatent p 27 53 368.2 (a. 3573) relating to a process for the processing of the production of kernreaktorbrenn and / or nuclear fuel waste ammoniumnitrathaltigen abfalloesungen.the proposed method has the advantage that spruehloesungen with these concentrations in zersetzungsofen can be safely processed.secondly, the reducing agent such as urea or without for solutions in ammonia concentration of about 60% for most simple way with security are met, by using a temporary storage in where appropriate gekuehlten behaeltern provides.furthermore, the evaporation of the abfalloesungen a ammoniumuranylcarbonat - faellungsprozesses, especially when about 60 degrees c), an additional ausfaellung of uranium, the abfiltriert and production can be zurueckgeschickt....u.s.w
