RADIOACTIVE EFFLUENT RELEASES Attached are tables which summarize radioactive releases from the plant. An independent laboratory performs some of the analyses on monthly composite samples. As a consequence, the November and December data do not contain strontium 89 or 90.

These data will be included in a future report as they become available.

1. Gaseous Effluents

a. Gross Radioactivity Releases (1) Total gross radioactivity releases were 6.32 E+2 curies. In addition 2.81 E+l curies of tritium were released.

(2) The maximum gross radioactivity release rate for a one hour period was 4.69 E+3 iCi/sec.

(3) Total gross radioactivity data by nuclide released are shown in Table II.

(4) The percent of the technical specification limit for noble gases is 3.79 E-2 percent.

b. Iodine Releases (1) Total Iodine radioactivity released during this reporting period was 1.22 E-4 curies of Iodine-131.

(2) This represented 2.03 E-5 percent of the technical specification limit.

c. Particulate Releases (1) Particulate radioactivity released during this reporting period was 2.09 E-5 curies.

(2) Gross alpha releases excluding background radioactivity were less than LLD.

(3) Total gross radioactivity of nuclides with half lives greater than eight days was 2.09 E-5 curies.

(4) The percent of the technical specification limit for particulate radioactivity with half lives greater than eight days was 5.30 E-7.

SEMI-ANNUAL OPERATING REPORT NO. 25 PAGE 2

2. Liquid Effluents

a. Total gross radioactivity released, excluding tritium and noble gases, was 1.10 E+l curies. The average con centration released to unrestricted areas was 1.86 E-8 PCi/mi.

b. The maximum concentration of gross radioactivity released to the unrestricted area was 1.69 E-6 pCi/ml.

c. The total tritium released to the unrestricted area was 2.32 E+3 curies. The average tritium concentration released to the unrestricted area was 3.93 E-6 Ci/ml. Alpha radio activity released to the unrestricted area was 1.24 E-4 curies.

The average alpha concentration was 2.10 E-13 iiCi/ml.

d. The total dissolved gas radioactivity released to the un restricted area was 1.81 E+l curies. This quantity yielded an average concentration of 3.07 E-8 pCi/ml released to the unrestricted area.

e. The volume of liquid waste released was 3.41 E+7 liters.

f. The total volume of dilution water was 5.90 E+ll liters.

g. Total gross radioactivity by nuclide is shown in Table I.

h. The percent of the technical specification limit for liquid releases is 2.92 E-1.

SOLID WASTE

1. Total amount of solid waste shipped was 2.95 E+3 cubic feet.

2. The total estimated radioactivity involved in the above shipments was 9.24 E+1 curies.

3. The shipments were made on March 15, 20, 23, 27 and 29 to Beatty, Nevada by Southwest Nuclear co. 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.

SEMI-ANNUAL OPERATING REPORT NO. 25 PAGE 3 ADDITIONS Table II, Airborne Releases, of Semi-Annual Operating Report No. 23 should be updated to indicate total tritium released for 1978 is 5.75 E-1 curies.

Table I, Liquid Releases of Semi-Annual Operating Report No. 24 should be up dated to include the revised data for the January-June period resulting from the additional gross alpha, C-14, Sr-89, Sr-90, Fe-55, Ni-63 and S-35 data.

Table II, Airborne Releases of Semi-Annual Operating Report No. 24 should be updated to include the revised data for the January-June period resulting from the additional gross alpha, Sr-89 and Sr-90 data.
