Abstract

The aim of this work is to present radiochemical methodologies developed at CDTN/CNEN in order to answer a program for isotopic inventory of radioactive wastes from Brazilian Nuclear Power Plants. In this program some radionuclides, ³H, ¹⁴C, ⁵⁵Fe, ⁵⁹Ni, ⁶³Ni, ⁹⁰Sr, ⁹³Zr, ⁹⁴Nb, ⁹⁹Tc, ¹²⁹I, ²³⁵U, ²³⁸U, ²³⁸Pu, ^239+240Pu, ²⁴¹Pu, ²⁴²Pu, ²⁴¹Am, ²⁴²Cm e ^243+244Cm, were determined in Low Level Wastes (LLW) and Intermediate Level Wastes (ILW) and a protocol of analytical methodologies based on radiochemical separation steps and spectrometric and nuclear techniques was stablished.
