10 CFR 61 qualification testing of ORNL radioactive liquid low level waste

OSTI ID:6972964

The stabilization of low level liquid waste (LLLW) from nuclear power plants with cement based formulations is routinely performed in an efficient, safe and cost-effective manner. The stable waste form is subsequently buried in a government regulated shallow land burial site. The waste generated at Oak Ridge and stored in the Melton Valley Storage Tanks is dissimilar in several respects to nuclear station waste. The ORNL waste has a high pH and contains a large concentration of nitrates. Such characteristics can affect the long term stability of the LN solidified product. The development of a stabilization formula is normally performed using a non-radioactive surrogate waste form. This procedure, approved by the Nuclear Regulatory Commission, eliminates any radiation exposures to laboratory personnel and any radioactive waste during the qualification period. It is important, therefore, to formulate a surrogate waste which simulates the actual waste. The MMES staff at ORNL identified a surrogate waste form which is described in detail in Attachment 3. Included in this attachment is the ''recipe'' to produce the surrogate waste developed by MMES/ORNL and followed by LN laboratory personnel. 7 refs.
