SAN ONOFRE NUCLEAR GENERATING STATION SEMI-ANNUAL OPERATING REPORT NO. 24 FOR THE PERIOD INCLUDING JANUARY 1, 1979 to JUNE 30, 1979 SUBMITTED IN ACCORDANCE WITH:
OPERATING LICENSE NO. DPR-13 SUBMITTED BY:
SOUTHERN-CALIFORNIA EDISON COMPANY SAN DIEGO GAS & ELECTRIC COMPANY 7908210
RADIOACTIVE EFFLUENT RELEASES Attached are tables which summarize radioactive releases from the plant for January through June, 1979. An independent laboratory performs some of the analyses. Consequently the following data will be included in a future report:
liquid releases, April, May and June gross alpha, C-14, Sr-89, Sr-90, Fe-55, Ni-63 and S-35; airborne releases, April, May and June gross alpha.
- 1. Liquid Effluents
- a.
Total gross radioactivity released, excluding tritium and noble gases, was 9.68 E-1 curies. The average concentration released to the unrestricted areas was 3.44 E-911Ci/ml.
The maximum concentration released to the unrestricted area was 1.87 E-7 iCi/ml.
- b. The total tritium released to the unrestricted area was 1.03 E+3 curies resulting in an average concentration of 3.67 E-61jCi/ml.
- c. The total dissolved noble gas radioactivity released to the unrestricted area was 9.23 curies resulting in an average con centration of 3.28 E-811Ci/ml.
- d.
No alpha radioactivity was detected in the January through March effluent.
- e. The volume of liquid waste released was 2.79 E+7 liters.
The volume of dilution water was 2.81 E+ll liters.
- f. The specific radionuclide composition of the effluent is shown in Table I.
- h. The percent of the technical specification limit for liquid releases, excepting analyses not yet completed was 1.28 E-1.
- 2. Airborne Effluents
- a. Total noble gas radioactivity was 1.67 E+2 curies. The maximum release rate was 4.34 E+3 NCi/sec. The percent of technical specification limit was 2.89 E-2. Specific radionuclide composi tion of noble gas releases is listed in Table II.
- b. The only detectable radioidine release occurred in June during sphere purge. The amount was 1.22 E-4 curies, and the percent of technical specification limit was 4.97 E-5.
- c. The only detectable particulate radioactivity release was in June during sphere purge. The amount was 1.59 E-5 curies and the percent of technical specification limit was 6.29 E-7. Com position of the particulate effluent is shown in Table II.
SAN ONOFRE NUCLEAR GENERATING STATION PAGE 2 SEMI-ANNUAL OPERATING REPORT NO. 24 WASTE
- 1. The total amount of waste shipped was 2.95 E+3 cubic feet.
- 2. The total estimated radioactivity shipped was 9.24 E+l curies.
- 3. The shipments were made on March 15, 20, 23, 27 and 29 to Beatty, Nevada by Southwest Nuclear Company for burial.
Also a shipment was made on June 28 to Beatty, Nevada by Nuclear Engineering, Inc.
and a shipment was made on June 29 to Richland, Washington by Nuclear Engineering, Inc.
