“…LLLW collected from the HFIR is generated primarily from the following sources: (1) regeneration and backwashing of primary and pool demineralizaticm systems, (2) waste from sampling, (3) head tank overflow, (4) gaseous waste l'ilter pit, (5) 7911 stack drainage, and (6) the off-gas condensate collection pit. When ttFIR was shut down, the LI,LW gencraticm rate was approximalely 27 O and 9°Sr in the LLLW System. Estimated losses of each material to the LLLW System were on the order of 15,000 el/year for each isotope.…”
