Dear Mr. Day:
~ ~ ' '
f Thank you for your letter of August 18, 1987, with the enclosed copies of correspondence concerning asphalt waste forms and the concept of administrative backfill procedures. As you know, and as the correspondence confirms, the issue of how to deal with the viscoelastic nature of bituminized low-level radioactive waste has been a difficult one to resolve. However, the NRC staff has, after careful study of several options, concluded that bituminized waste forms should be shown to have (a) a minimum compressive strength of 60 psi, as demonstrated by a uniaxial compression test, or (b) an equivalent shear strength, as demonstrated by a triaxial compression test. We discussed this with you by telephone on August 17, 1987, as well as at the LLW Forum in Denver, and it is our understanding that you believe ATI will be able to demonstrate that their waste forms will have the necessary strength values.
With regard to your plans for processing the Dresden NS-1 waste and the statement (in the. August 18 letter) that "ATI understands that we are at no risk to proceed," there may, in fact, be some risk involved in view of the fact that the topical report that we are reviewing does not address bituminized chelating agents such as the Dresden NS-1 waste form. It is our understanding that current sited states permit disposal of solidified wastes and high integrity containers that are currently under review under the NRC topical report system. However, since your topical report appears not to address the Dresden NS-1 waste stream, we believe that you may have some risk in proceeding with this plan to process Dresden NS-1 waste.
I should like to make clear that the State of Washington has the authority to decide what types of waste it will accept at Hanford within the provisions associated with Agreement State status.
