Dear Mr. Jensen:
The Nuclear Regulatory Commission has completed its review of topical report, DT-VERI-LOO NP/P, "VERl* (Vinyl Ester Resin In Situ) Solidification Process for Low Level Radioactive Waste."
The technical review included information contained in t.he topical report (TR), and further information that was submitted as a result of the review.
The Technical Evaluation Report (TER) fo-this review in enclosed.
We have concluded that the topical report supplemented by additional information that was provided in response to staff comments and questions adequately describes low level radioactive waste forms produced through uce of the VERl* process.
This process applies to the solidification of two waste streams, mixed bed bead resins, and ILM1 resins.
We also conclude that the solidified waste forms described meet the structural stability requirements of 10 CFR 61 for the disposal of Class 15 and Class C wastes.
These conclusions are predicted based on satisfactory completion of a final revised topical report which should include all applicable information developed during the technical review, a copy of the enclosed TER, and the following conditions:
1.
The VERT
- waste solidification process shall be used in accordance with the limitations called out in Section 3.1 of this Technical Evaluation Report, and all additional restrictions and requirements specified by the disposal facility operators and governing state agencies.
2.
Diversified Technologies must notify users of the VERI
- waste solidification process that they shall certify that all restrictions and required procedures have been adhered to, and that the waste forms do l
not contain proscribed chemicals or waste materials.
l l
3.
Diversified Technologies must characterize the chemical nature of the resins used in the qualification tests so that users of the process can l
know what kind of resins can be satisfactorily solidified.
This information must be clearly specified in the final revised TR and operating procedures, t
4.
Diversified Technologies must resolve the outstanding issues specified in Section 3.2 of the enclosed TER.

It should be noted that notwithstanding NRC's decisions on the adequacy of t.he VERI" polymer solidified wastes, the sited States have regulatory authority concerning the conditions of acceptance of waste forms at their disposal facilities.
It is therefore the licensee's responsibility to contact the State regulatory authorities to det ermine _ the acceptability of the polymer solidified wastes at their State's facilities.
copies of the enclosed TER and this letter are being forwarded to the States of Nevada, South Carolinn and Washington for their information and use.
If you have any questions on this matter, please contact me at (301) 504 3450, or Jennifer Davis at (301) 504-2697.
