Re: TRU vs LLW classification



TRU waste is defined as waste that contains more than 100 nCi/gram of elements heavier than uranium.  However, according to the WIPP Land Withdrawal Act, only "defense-generated" waste can go to the WIPP for disposal.  So non-defense waste that meets the TRU definition wouldn't be accepted for disposal at the WIPP.  Actually  the EBR-II waste falls into this category of TRU waste that is not defense-generated.

A great deal of TRU waste could be categorized as LLW Class C (or A or B).  In fact, about 10% of the identified TRU waste meets the criteria for LSA.
