Schoci of Engineering Vanderbilt University Nashville, Tennessee 37203
Dear Dr. Parker:
This letter is in response to your letter of January 3,1981 in which you request additional information to aid the NCRP Task Group SC-38 on Disposal of Accident Gener'ated Waste Water in the NCRP evaluation of the disposition of processed THI-2 accident generated waste water. The requested infomation is provided herein.
I apologize for the tardiness of this submittal. I realize that the Task Group has been given an extremely difficult task and I appreciate the Task Group efforts to provide an evaluation in a time frame consistent with the preparation of our Final Programatic Envinnmental Impact Statement Related to Decontamination and Disposal of Radioactive Wastes Re-sulting from March 28, 1979 Accident, Three Mile Island Nuclear Station, Unit 2. is the ORIGEN code listing of the radionuclide distribution and curie inventory in the core at the time of the TMI-2 accident on March 28, 1 979, and at various time intervals thereafter through 3,750 days of decay.
! is a letter dated September 28, 1979, from Hamid Denton, Director, Office of Nuclear Reactor Regulation, to Vincent Johnson, Director, Technical Staff, President's Comission on the Accident at Three Mile Island, which discusses the fate of various radionuclides (iodines, noble gases) during the THI-2 accident. is Section 5.4, RADIOLOGICAL IMPACTS, of the Final Supplement to the Final Environmental Statement Related to Operation of Three Mile Island l
Nuclear Station, Unit 2 (NUREG-0112), dated December 1976.
' is Section 2.3, METEOROLOGY, of the Final Safety Analysis Report for Three Mile Island Nuclear Station-Unit 2, dated April 4,1974 is the projected population distribution around the Three Mile Island Nuclear Station to a distance of 50 miles for the years 1980, 1990, 2000 and 2010. is a listing of the on-site meteorological data for the years 1972 through 1977 (mid-year) and updates the meteorological data contained in En-closure 4 0 I g9 09M p 83
h h>8 r
Dr. Frank Parker Enclosure 7 is an internal NRC staff memorandum which discusses the parameters and factors asstsned in the evaluation of the environmental impact of evaporating tritiated water from an onsite holding pond. Note that the meteorological dis-persion factors used in the staff analysis are based on the updated on-site meteorological data for the years 1972-1975 (see Enclosure 6).
Enclosum 8 is a draft Appendix for the final Progrannatic Environmental Impact Statement which describes the staff's calculational models and parameters used in estimating maximum individual and population doses re ulting from releases of radioactive materials in liquid and gaseous effluents to unrestricted areas from cleanup activities at the TMI-2 plant. is Section 2.4, HYDROLOGIC ENGINEERING, of the Final Safety Analysis Report for Three Mile Island Nuclear Station-Unit 2, dated April 4,1974 If you have any questions regarding the infonnation centained in the above enclosures, or desire to talk with staff specialists in meteorology, hydrology or dose assessment, please contact Rick Weller (301-492-8174) of ry staff.
Sincerely, Bernard J. Snyder, Program Director TMI Program Office Office of Nuclear Reactor Regulation
