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.
