I INTRODUCTION This Effluent and Waste Disposal Report is submitted as required by Technical Specification 5.6.1.B of Appendix B to the Crystal River - Unit 3 Fa,cility Operating License No. DPR-72. The data in this report covers the period from July 1 to December 31, 1973.

There have been no changes to the Technical Specification Requirements for effluents and waste disposal in Appendix B of the Facility Operating License during the period of this report.

Crystal River - Unit 3 has had no measurable radiological impact on the surrounding environment during the reporting period. This is based on the Radiological Environmental Monitoring Program showing no increases over preoperational data and the doses calculated for individuals and the popu-lation due to effluent releases being significantly below the levels required by 10 CFR 50, Appendix 1.

The sumations of gaseous and liquid effluents, solid waste shipments and meteorological data are in accordance with the tables in Regulatory Guide 1.21 (Rev.1, 6/74) Appendix B.

The individual and population doses were calculated using the GASPAR (for gaseous effluents) and the LADTAP (for liquid effluents) computer codes obtained from the Nuclear Regulatory Commission and revised to include site specific data wherever possible. These doses are summarized in Tables 1-1A and B.

The values reported for the activity of nuclides released are the actual measured activities. If no activity for a nuclide was detected for a quar-ter, the total of the lower limits of detection for all samples is reported as "<X.XXE-X". The totals of activity released is a total of only the nuclides that had measured activity.

!! RELEASES OF AND DOSES FROM GASEOUS EFFLUENTS There are three normal methods of releasing gaseous effluents to the atmosphere: 1) continuous release via the Auxiliary Building Exhaust; 2) batch release from the Waste Gas Decay Tanks; and 3) Reactor Building purge. All three methods release to the atmosphere from one point, the Phint Vent.

1. Regulatory Limits The Technical Specification limits for gaseous effluent releases are as follows:

Specification 2.4.2 The tenns used in these Specifications are as follows:

2. Maximum Permissible Concentrations The maximum pemissible concentrations of nuclides in gaseous releases is based on the resultant doses at the site boundary as determined from the concentrations of nuclides at the release point. The Technical Specifications provide the equations and dose factors that relate the gaseous activity to be released to doses at the site boundary and restrictions are placed on instantaneous, quarterly and yearly release rates. The gaseous releases do not exceed the concentration limits specified in 10CFR20 and are as low as reasonable achievable in accordance with the requirements of 10CFR50.

3. Measurements and Approximations of Total Radioactivity The gaseous effluent release via the Auxiliary Building Exhaust is treated as a continuous release subdivided into discrete periods of filter changes and the radioactivity measured as follows:

A. Fission and Activation Gases - The total activity released is detemined fra the net count rate of the gaseous monitor [RMA-2G],

its calibration factor, and the total exhaust flow. The activity of radiogas is detemined by the fraction of that radiogas in the isotopic analysis of the Auxiliary Building atmosphere for that period.

B. Iodines - The activity released as lodine-131,133, and 135 is based on the charcoal cartridge activities (RMA-21), the particulate filters activities (RMA-2P) and the total vent flow.

C. Particulates - The activity released via particulates with half-lives greater than eight days is detemined by isotopic analysis of particulate filters (RMA-2P) and the total vent flow.

D. Tritium - The activity released as tritium is based on monthly grab sample analysis and total vent flow.

The radioactivity released by batch releases of the Waste Gas Decay Tanks via the Auxiliary Butiding Exhaust is measured as fo'10ws:

A. Fission and Activation Gases - The activity released is based on the volume released and the activity of the individual nuclides obtained from an isotopic analysis of the grab sample taken prior to the release.

B. lodines - The iodines from batch releases are included in the iodine detemination from the continurus Auxiliary Butiding releases.

C. Particulates - The particulates from batch releases are included in the particulate determination frm the continuous Auxiliary Building release.

D. Tritium .The activity released as tritium is based on the grab sample analysis of each batch and the . itch volume.

8

The radioactivity released by purge releases of the Reactor Building through the Reactor Building vent is measured as follows:

A. Fission and Activation Gases - The activity released is determined from the net count rate of the gaseous monitor (RMA-1G), the monitor calibration factor and the total vent flow. The release of each radi-ogas is a product of the total curies released times the fraction of that radiogas in the isotopic analysis for that purge.

B. Iodines - The total curies released as iodine-131, 133 and 135 was determined from the charcoal cartridge activities (RMA-11) and the particulate filter activities (RMA-1P).

C. Particulate - The total curies released via particulates with half-lives greater than eight days is detennined by isotopic analysis of each purge particulate filter (RMA-1P).

D. Tritium - The total curies released as tritium is based on grab samples taken for each purge (or the average if more than one grab sample was taken).

4. Batch and Unplanned Releases The batch gaseous effluent releases may be summarized as follows:

III RELEASES OF AND DOSES FROM LIQUID EFFLUENTS There are two sources of liquid ef fluents released to the discharge canal:

1) the Laundry and Hot Shower Sump and 2) the Evaporator Condensate Storage Tanks. Both are batch type releases made through the plant liquid release m,pnitor, RML-2. There is one source of liquid effluents released to the Chemical / Industrial Waste Water Ponds: the turbine building sump. This is a continuous mode type release and the measurementh and calculations will be described in Supplement I to this report.

1. Regulatory Limits The Technical Specification limits for liquid effluent releases are as follows:

Specification 2.4.1 A. The instantaneous concentration of radioactive materials released in liquid waste effluents from all reactors at the site shall not exceed the values specified in 10 CFR Part 20, Appendix B,

'able !!, Column 2, for unrestricted areas.

B. The cumulative release of radioactive materials in liquid waste effluents excluding tritium and dissolved gases, shall not exceed 10 Ci/ reactor / calendar quarter.

C. The cumulative release of radioactive materials in liquid waste effluents excluding tritium and dissolved gases, shall not exceed 20 Ci/ reactor in any 12 consecutive months.

D. During release of radioactive wastes, the effluent control moni-tor shall be set to alarm and to initiate the automatic closure of each waste isolation valve prior to exceeding the limits specified in 2.4.1.A above.

E. The operability of each automatic isolation valve in the liquid radwaste discharge lines shall be demonstrated quarterly.

F. The equipment installed in the liquid radioactive waste system shall be maintainea and shall be operated to process radioactive liquid wastes prior to their discharge when the projected cumula-tive release could exceed 1.25 C1/ reactor / calendar quarter, ex-cluding tritium and dissolved gases.

G. The maximum radioactivity to be contained in any liquid radwaste tank that can be discharged directly to the environs shall not exceed 10 Ci, excluding tritium and dissolved gases.

H. If the cumulative release of radioactive materials in liquid effluents, excluding tritium and dissolved gases, exceeds 2.5 Ci/ reactor / calendar quarter, the licensee shall make an investi-gation to identify the causes for such releases, define and ini-tiate a program of action to reduce such releases to the dcsign objective levels listed in Section 2.4, and a report of these actions shall be made to the USNRC in accordance with Section 5.6.2.C(1).

17

2. Maximum Permissible Concentrations The maximum pemissible concentration values used in detemining allowable liquid radwaste release concentrations are taken from 10 CFR Part 20, Appendix B Table II, Column 2. Release rate and dilution ratio for each batch are determined oy a mixed nuclide MPC calculation performed before th.e release of the batch. To facilitate the measurements and calculations, the nuclides of Column 2 which can be produced in a fission reactor have been grouped according to MPC value and type of radiation as shown in Figure 111-1.

The concentration of each of the 23 gamma emitting nuclides specifically noted in Figure 111-1 is measured individually because of interest in that nuclide. For any of the 23 nuclides not detected in the gamma scan, the MDA Limit is computed from the measured data for that sample.

Only two pure beta emitters, Sr-89 and Sr-90, have MPC values less than 9 x10-6 uC1/ml. Individual measurements are made on proportional composite liquid radwaste samples to detemine the Sr-89 and Sr-90 concentration or MDA value to be applied to individual batch release calculations.

Although the MPC limit for tritium is greater than 9 x 10-6 pCi/ml, a separate measurement is made for tritium. A distillation and liquid scintillation counting technique is used to measure tritium concentration.

The measured and calculated concentration values for each batch are used to calculate the dilution ration, release rate, and dilution rate prior to release of each batch. Both the concentration and release data are stored on a computer disc file. The disc file data is used to assure that quarterly and annual release limits are not exceeded. Bases used for the data of Table Ill-1 are as follows:

A. Fission and activation products - The total release values (not including tritium, gases, alpha) are comprised of the sum of the individual radionuclide activities in each batch released to the discharge canal for the respective quarter. These values represent the activity known to be present in the liquid radwaste effluent.

Percent of applicable limit is detemined from a mixed nuclide MPC calculation. The average concentration for each nuclide summed over all batches is divided by the corresponding individual MPC value. The sum over all nuclides of the Ci/MPCi ratios times 100 is the percent of applicable limit for effluent releases during the quarter.

B. Tritium - The measured trit'ium concentration in a composite simple is used to calculate the total release and average diluted concentration during each period. Average diluted concentration divided by the MPC limit, 3 x 10-3 pCi/ml, is converted to percent to give the percent of applicable limit.

18

C. Dissolved and entrained gases - Concentrations of dissolved and entrained gases in liquid effluents are measured monthly by Ge(L1) spectroscopy on a one liter sample from a representative liquid radwaste batch. Dissolved and entrained gases for which measured or MDA concentrations are detennined include noble gases with half lives greater than 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />s: Xe-135, Xe-133m, Xe-133, and Kr-85. lodine

~

radionuclides in any fonn arc detennined during the isotopic analysis for each batch, therefore a separate analysis for possible gaseous forms is not performed because it would not provide additional information.

A conservative release limit, the maximum sensitivity limit of 4 x 10-5 pct /ml of each dissolved and entrained radionuclide as specified in Table Note 5, Table 2.4-1, Environmental TechA31 Specifications, has beer applied in detennining the grcent of applicable limit.

3. Measurements and Approximations of Total Radioactivity Details of the analytical procedures for liquid radwaste analysis are as follows:
