515 Fest Point Avenue University City, MO 63130 28 November 1979 Commissioner Richard T.
Kennedy U.S.
Nuclear Regulatory Commission Washington, D.C.

Dear Commissioner Kennedy:
- W:TC g,c In Enclosure 1 regarding contaminated water at TMI submitted with your letter of October 1, 1979 to Senator Gary Hart and others, mention is made on page 7 of the plan to have licensee implement a groundwater monitoring program to determine if radioactive water from the reactor building is leaking through the base mat as yet. Fould you please tell me if the monitoring wells have been installed, and if so, if tests have detected any leakage thus far?
While not relevant to the TMI decontamination project, the EPICOR environmental assessment mentions the " chemical cleaning of steam generators," planned for operating the plant under routine conditions.
Could you please refer me to a document that would describe how the chemical cleaning of the generators was to have been performed in a separate building -- and how often? Is it anticipated that chelating agents would be used to remove the corrosion products? Has any operative plant ever dismantled its steam generator (or tubes) for chemical cleaning as yet? How is the effluent containing the chemical solvent and dissolved contaminants disposed of, e.g.,
from the chemical cleaning solution tank mentioned on page 5?
I read that the EPICGR-II system got clogged up when it was first put into operation. Fould you please tell me how much time was needed before the clogging problem was remedied? Is the EPICOR system functioning at this time, and if so, what percent of the auxiliary building tanks have already been processed? Is there any effort to remove the tritium, or is the necessary technology not yet developed or economically feasible for such great quantities of water?
Thank you.
Sincerely, Mrs. Leo A.
