I INTRODUCTION This Effluent and Waste Disposal Report is subnitted per Technical Specification 5.6.1.B of Appendix B to,the Crystal River - Unit 3 Facility Operating License No. DPR-72. The data in this report covers the period from July 1 to December 31, 1977.

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 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 population due to effluent releases being significantly below the levels required by 10 CFR 50, Appendix I.

The summations 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 I-1A and B.

The values rep'orted for the activity of nuclides released are the actual measured activities.

If no activity for a nuclide was detected for a quarter, 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.

II 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 Plant Vent.

1.

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

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

subscripts v, refers to vent releases 1, refers to individual noble gas nuclide (Refer to Table 2.4-5 for the noble gas nuclides considered) j Q = the total noble gas release rate (Ci/sec)

T

= r,Q4 sum of the individual noble gas radionuclides determined t6 be present by isotopic analysis

)

K = the average total body dose factor due to gama emission (rem /yr per Ci/sec)

E = the average skin dose factor due to beta emissions (rem /yr perCi/sec) ii = the average air dose factor due to beta emissions (rad /yr perCi/sec)

II = the average air dose factor due to gamma emissions (rad /yr perCi/sec)

The values of K, C, R and fi are to be determined each time isotopic analysis is required as delineated in Specification 2.4.2.J.

Determine the following using the results of the noble gas radionuclide analysis:

i K = (1/Q ) r0 K T

The operability of each automatic isolation valve listed in Table 2.4-4 shall be demonstrated quarterly.

E.

The maximum activity to be contained in one waste gas storage tank shall not exceed 47,000 curies (considered as Xe-133).

2.

Maximum Permissible Concentrations The maximum permissible 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 4

specified in 10CFR20 and are as low as reasonably achieveable in ac-cordance 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 by filter changes and the radioactivity measured as follows:

A.

Fission and Activation Gases - The total activity released is determined from the net count rate of the gaseous monitor [RMA-2G],

its calibration factor, and the total exhaust flow.

The activity i

of radiogas is determined by the fraction of that radiogas in the isotopic analysis of the Auxiliary Building atmosphere for that period.

B.

Iodines - The activity released as fodine-131,133, and 135 is based on the charcoal cartridge activities (RMA-2I) 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 determined 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.

4 The radioactivity released by batch releases of the Waste Gas Decay Tanks via the Auxiliary Building Exhaust is measured as follows:

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.

Iodines - The iodines from batch releases are included in the iodine determination from the continuous Auxiliary Building release.

C.

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

D.

Tritium - The activity released as tritium is based on the grab sample analysis of each batch and the batch 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 deter-mined from the net count rate of the gaseous monitor (RMA-lG),

the monitor calibration factor and the total vent flow.

The release of each radiogas 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-lI) and the particulate filter activities (RMA-lP).

C.

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

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:

Third Fourth Quarter Quarter Number of Batch Releases 7.00E+00 2.10E+01 Total time for all releases (minutes) 1.91 E+04 7.91E+04 Maximum time for any one release (minutes) 9.80E+03 1.19E+04 Average time for all releases (minutes) 2.72E+03 3.60E+03 i

An extensive review of Surveillance Documentation retained in accordance with Environmental Technical Specification 2.4.2F revealed documentation for sixteen analyses that met or exceeded that required by ETS 2.4.2J were not available. Discrepancy reports were prepared detailing the methods for estimating releases for periods in which documentation was absent.- Corrective action initiated during the third quarter because of fifteen unavailable analyses has resulted in only one unavailable analysis for the fourth quarter.

The unplanned releases for the third and fourth quarters of 1977 are listed below giving the date, the Licensee Event Report Number and the cause of each release.

III RELEASES OF AND DOSES FROM LIQUID EFFLUENTS There are two sources of liquid effluents released to the dischat se canal: 1) the Laundry and Hot Shower Sump and 2) the Evaporator Con-densate Storage Tanks. Both are batch type releases made through the plant liquid release monitor, Rf1L-2.

1.

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

Specification 2.4.1 A.

The instcntaneous 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, Table II, 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 cumulativ,. release of radioactive materials in liquid waste effluent excluding tritium and dissolved gases, shall not exceed 20 Ci/ reactor in any 12 consecutive months.

D.

During release of radioactive wastes, the effluent controi monitor 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 maintained and shall be operated to process radio-

~~

active liquid wastes pricr to their discharge when the pro-jected cumulative release could exceed 1.25 Ci/ reactor / calendar quarter, excluding tritium and dissolved gases.

G.

The maximum radioactivity to be contained in any liquid rad-waste 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 in-vestigation to identify the causes for such releases, define and initiate a program.of action to reduce such releases to the design objective levels listed in Section 2.4, and a report of these actions shall be made to the USNRC in accord-ancewithSection5.6.2.C(l).

17

2.

Maximum Permissible Concentrations The maximum permissible concentration values used in determining allow-able liquid radwaste release conceritrations are taken from 10 CFR Part 20, Appendix B, Table II, Column 2.

Release rate and dilution ratio for each batch are detennined by a mixed nuclide MPC calculation performed before the 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 III-1.

The concentration of each of the 23 gama emitting nuclides specifically noted in Figure III-l 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 twg pure beta emitters, Sr-89 and Sr-90, have MPC values less than 9 x 10- uCi/ml.

Individual measurements are made on proportional 4

composite liquid radwaste samples to determine the Sr-89 and Sr-90 concentration or MDA value to be applied to individual batch release calculations.

4 Although the MPC limit for tritium is greater than 9 x 10-6 uCi/ml, a separate measurement is made for tritium. A distillation and liquid 4

scintillation counting technique is used to measure tritium concentration.

These measured and calculated concentration values for each batch are used to calculate the dilution ratio, 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 i

assure that quarterly and annual release limits are not exceeded. Bases used for the data of Table III-l 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 determined from a mixed nuclide f1PC i

calculation. The average concentration for each nuclide sunined, over all batches is divided by the corresponding individual itPC i

value. The sum over all nuclides of the Ci/MPC1 ratios times 100 is the percent of applicable limit for effluent releases during the j

quarter.

l B.

Tritium - The measured tritium concentration in a composite sample is used to calculate the total release and average diluted concen-tration during each perio by the MPC limit 3 x 10 g. Average diluted concentration divided uCi/ml, is converted to percent to give the percent of applicable limit.

1 18

C.

Dissolved and entrained gases - Concentrations of dissolved and entrained gases in liquid effluents are measured monthly by Ge(Li) spectroscopy on a one liter sample from a representative liquid radwaste batch. Dissolved and entrained gases for which measured or MDA concentrations are determined 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, 0-133m, Xe-133, and Kr-85.

Iodine radionuclides in any form are determined during the isotopic analysis for each batch, therefore a separate analysis for possible gaseous forms is not performed because it would not provide addi-tional information.

A consegvative release limit, the maximum sensitivity limit of 4 x 10~ pCi/ml of each dissolved and entrained radionuclide as specified in Table Note 5, Table 2.4-1, Environmental Technical Specifications, has been applied in determining the percent of applicable limit.
