SUMMARY OF RADIOACTIVE WAS TE DISCHARGES TO THE ENVIRONMENT

FROM PRESS URI ZED WATER REACTORS

1959-1970

This appendix summarizes discharges of radioactive was tes from the pressurized water reactors operating in the United States from 1959 to 1970, except for the Saxton Nuclear Experiment al Reactor, which has a net electrical capacity of only 3.25 megawatts.

It should be noted that 10 CFR Part 20 provides alternatives for determining permissible limits to the activity of radioactive liquid effluents. One of the limits specifically mentioned is 1 x 10-7 microcurie per cubic centimeter, which is sufficiently restrictive that it can be used for mixtures of fission and corrosion products in liquid was te from light water nuclear power reactors without any identification of the radioisotopic composition of the mixture. Other alternatives require knowledge of the identity and concentration of the radionuclides present and es tablishing that certain isotopes are not present. Typical compositions of radioactivity in water from light water power reactors are such that much higher limits are expected to be available to the licensee if he wishes to support ther by adequate radiochemical analyses. The values reported in Table III1-1 were calculated using the limit of 1 x 10-7 micro curie per cubic centime ter, except as noted.

The corresponding 10 CFR Part 50 guideline (June 9, 1971) is 0.2 x 1077 mi crocurie per cubic centimeter, a value one-fifth as large as the 10 CFR Part 20 limdt; 10 CFR Part 50 makes no provision for analysis for specific radionuclides. There fore the per cent of limit values in Table III-1-1 (for 10 CFR Part 20 limits) may be converted to the percent of the 10 CFR Part 50 guideline by multiplying these values by 5, except for the instances where the licensee analyzed the discharge for specific radionuclides. In these cases, the 10 CFR Part 50 guideline of a maximum discharge of 5 curi es per reactor can be used for comparative purposes.

The values for 1959-1968 are from "Radioactive Was te Discharges to the Envi ronment from Nuclear Power Facilities," J. E. Logs don and R. I. Chissler, u.s. Dept. of Health, Education and Welfare, PB-190717 (BRH/DER 70-2) March 1970.

The values for 1969 are from Hearings Before the Joint Committee on Atomic Energy. Congress of the United States, 9 1st Congress, Second Session, on Environmental Effects of producing Electric Power, January 27-30, February 24-26, 1970, Appendix 10, pp. 2316-2317.

The values for 1970 are from B. Kahn, B. Shleien, and C. We aver, in Vol. 2 of U.S. Papers for the Fourth United Nations International Conference on the Peaceful Uses of Atomic Energy, Geneva, Switzerland, Sept. 6-16, 1971, Session 3.3-28- to 3.3-45, A/Conf-49/P-087.
