1、Designation:C146319Standard Practices forDissolving Glass Containing Radioactive and Mixed Wastefor Chemical and Radiochemical Analysis1This standard is issued under the fixed designation C1463;the number immediately following the designation indicates the year oforiginal adoption or,in the case of
2、revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 These practices cover techniques suitable for dissolvingglass samples that may contain nuclear wastes.
3、These tech-niques used together or independently will produce solutionsthat can be analyzed by inductively coupled plasma atomicemission spectroscopy(ICP-AES),inductively coupled plasmamass spectrometry(ICP-MS),atomic absorption spectrometry(AAS),radiochemical methods and wet chemical techniquesfor
4、major components,minor components and radionuclides.1.2 One of the fusion practices and the microwave practicecan be used in hot cells and shielded hoods after modificationto meet local operational requirements.1.3 The user of these practices must follow radiation pro-tection guidelines in place for
5、 their specific laboratories.1.4 Additional information relating to safety is included inthe text.1.5 The dissolution techniques described in these practicescan be used for quality control of the feed materials and theproduct of plants vitrifying nuclear waste materials in glass.1.6 These practices
6、are introduced to provide the user withan alternative means to Test Methods C169 for dissolution ofwaste containing glass in shielded facilities.Test MethodsC169 is not practical for use in such facilities and withradioactive materials.1.7 The ICP-AES methods in Test Methods C1109 andC1111 can be us
