The 2020 annual 2H and 3H Evaporator overhead samples were received at Savannah River National Laboratory (SRNL) on December 22, 2020. The delivered samples were analyzed for concentration of cesium-137 (¹³⁷Cs), strontium-90 ⁽⁹⁰Sr) and iodine-129 (¹²⁹I) to validate compliance with the Effluent Treatment Project Waste Acceptance Criteria (ETP WAC, Rev. 7). The concentration of all three radionuclides, ¹³⁷Cs, ⁹⁰Sr, and ¹²⁹I, in the 2H Evaporator overhead sample were found to be less than the corresponding ETP WAC limits. Radiochemical analysis of the 3H Evaporator overhead sample indicated a ¹³⁷Cs content about an order of magnitude higher than the acceptable threshold value, and ⁹⁰Sr and ¹²⁹I concentrations within the acceptance limits.
