3. The' dose to a member of the public at or beyond the site boundary .

from iodine-131 and particulates with half lives greater than  !

eight days in gaseous effluents shall not exceed (Technical Specification 3/4.11.2.3):

15 mrern/qtr, any orgu 30 mrem / year, any organ  ;

less than 0.1% of the above limits as a result of burning contaminated oil. ,

4. All of the above parameters are calculated according to the methodology specified in the ODCM.  :

C. Liouid Effluents

1. The concentrations of radionuclides in liquid effluents from the l plant shall not exceed the values specified in 10 CFR Part 20, [

Appendix B, for unrestricted areas (Technical Specification 3/4.11.1.1).

l 2. The liquid radwaste treatment system shall be used to reduce the t I concentration of radionuclides in liquid effluents from the plant 1 when the calculated doses to unrestricted areas exceed 0.36 mrem to the whole body, or 1.20 mrem to any organ in a 92 day period (Technical Specification 3/4.11.1.3).

4. All of the liquid dose parameters are calculated according to the methodology specified in the ODCM.

II. MAXIMUM PERMISSIBLE CONCENTRATIONS A. Fission and Ac+ivation Gases Prior to the batch release of gaseous effluents, a sample of the source is collected and analyzed by gamma spectroscopy for the principal gamma emitting radionuclides. The identified radionuclide ,

concentrations are evaluated and an acceptable release rate is determined to ensure that the dose rate limits of Technical Specification 3/4.11.2.1 are not exceeded.

y 1 o ,

, \

B. Iodines and Particulates with Half Lives Greater than Eioht Day 1 ,

a Compliance with the dose rate limitations for iodines and particulates ,

is demonstrated by analysis of the charcoal and particulate samples of the station main vents. The charcoal samples are analyzed by gamma spectroscopy for quantification of any release of radioiodines. The particulate samples are analyzed by gamma spectroscopy for quantification of particulate radioactive material. Based on guidance provided in the ODCM, compliance with dose rate limits for the radioiodines and particulates may be based on a comparison of the actual measured release quantity over a sample period with a pre-established upper bound.

C. Liouid Effluents ,

The MPCs used for radioactive materials released in liquid effluents are in accordance with Technical Specification 3/4.11.1.1 and the ,

values from 10 CFR 20, Appendix B, including applicable table notes.

In all cases, the more restrictive (lower) MPC found for each radionuclide is used regardless of solubility.

III. TECHNICAL SPECIFICATION REPORTING REQUIREMENTS (Section 6.9.1.8)

A. Previous Calendar Year (QQ9LQose Assessment Summary During 1989 liquid releases from Calvert Cliffs resulted in a calculated maximum organ dose of 5.38E-01 mrem and a maximum whole  :

body dose of 4.74E-02 mrem. These doses are less than 3% of the Technical Specification yearly organ dose limit and less than 1% of the Technical Specification year' y dose limit for the whole body.

These doses were calculated using ODCM methodology. The controlling pathway was the fish and shellfish pathway with adult as the controlling age group, and the Gastro-Intestinal Tract representing the organ with the highest calculated dose.

Gaseous releases of noble gases resulted in a maximum air dose of l.19E-01 mrad, gamma and 2.63E-01 mrad, beta. Iodine and particulate releases from Calvert Cliffs resulted in a maximum organ dose of 8.78E-01 mrem for the year via the milk-infant-thyroid pathway. These doses were calculated using ODCM methodology. For 1989, calculated offsite doses via the gaseous release pathways were below 3% of their allowable Technical Specification limits.

-B. 40 CFR 190 Total Dose Como11ance Based upon all releases for 1989 and the ODCM calculations, the maximum exposed individual would receive less than 3% of the allowable dose. During 1989, there were no on site sources of direct radiation that would have contributed to a significant or measurable offsite dose. The direct radiation contribution is measured by both on-site j and off-site thermoluminescent dosimeters (TLD). The results of these measurements did not indicate any statistical increase in off-site radiation doses attributable to on-site sources. Therefore, no increase in the off site calculated doses is attributable to the 3

direct exposure from on-site sources. A more detailed evaluation will be reported in the Annual Radiological Environmental Monitoring Report.

C. Eglid Waste Report Reouirements During the first half of 1990, the type of radioactive solid waste shipped from Calvert Cliffs was dry compressible waste, which was shipped as LSA waste in strong, tight containers. Table 3A summarizes the waste shipment data. Also, Appendix A provides a detailed breakdown of the waste shipments for 1990 per the categories as specified in Technical Specification 6.9.1.8.

D. ODCM and PCP Chances No changes were made in the PCP in the first half of 1990.

IV. AVERAGE ENERGY Not Applicable V. MEASUREINTS AND APPR0XIMATIONS AND TOTAL RADI0 ACTIVITY A. Fi Lion and Activation Gases

1. Batch Releases Prior to each batch release of gas from a pressurized gas decay tank, a sample is collected and analyzed by gamma spectroscopy using a Ge detector for the principal gamma emitting noble gas radionuclides. The total activity released is based on the pressure / volume relationship (gas laws) of the tank.

Prior to and after each containment purge, a gas sample is collected and enalyzed by gamma spectroscopy using a Ge detector for the principal gamma emitting noble gas radionuclides. The total activity released is based on containment volume and purge rate. Activity buildup while purging is also considered.

2. Continuous Releases A gas sample is collected at least weekly from the main vents and analyzed by gamma spectroscopy using a Ge detector for the principal gamma emitting noble gas radionuclides. The total activity released for the week is based on the total sample activity decay corrected to the midpoint of the sample period multiplied by the main vent flow for the week.

A monthly composite sample is collected from the main vents and analyzed by liquid scintillation for tritium. The total tritium release for the month is based on this sample analysis and the vent flow.

B. lodine and Particulates

1. Batch Releases The total activities of radioiodines and particulates released from a pressurized gas decay tank, containment purges and containment vents are accounted for by the continuous samplers on )

the main vent.

I

2. Continuous Releases i During' the release of gas from the main vents, samples of iodines i and particulates are collected using a charcoal and particulate  :

filter, respectively. The filters are removed weekly and are analyzed by gamma spectroscopy using a Ge detector for significant .

gamma emitting radionuclides. The total activity released for the .i week is based on the total sample activity decay corrected to the  !

midpoint of the sample period multiplied by the main vent flow for the week. 1hese weekly particulate filters are then composited to form monthly and quarterly composites for the gross alpha and strontium 89 and 90 analyses.

e t C. Liouid Effluents

1. Batch Releases Prior to the rele' *e of liquid from a waste tank, a sample is collected and an 'ed by gamma spectroscopy for the principal ,

gamma emitting r: *nuclides. To demonstrate compliance with the requirements 1 -sed in Section I.C.1 above, the measured radionuclide c, . rations ara comparu with the allowable MPCs; '

dilution in the . , charge conduit is considered, and an allowable release rate is verified. l The total activity released in each batch is determined by multiplying the volume released by the concentration of each radionuclide. The actual volume released is based on the difference in tank levels prior to and after the release. A proportional composite sample is also withdrawn for each release and this is used in turn to prepare monthly and quarterly composites for the gross alpha, strontium 89 and 90, and tritium analyses.

2. Continuous Releases When steam generator blowdown is discharged to the circulating water conduits, it is sampled daily and these samples are used in turn to prepare a weekly blowdown composite based on each day's L blowdown. The weekly compcsite is analyzed by gamma spectroscopy for the principal gamma emitting radionuclides. These results are multiplied by the actual quantity of blowdown to determine the total activity released. The weekly composite is also used to l

prepare monthly and quarterly composites for tritium, gross alpha, and strontium 89 and 90 analyses, l

b) Error in volume of liquid released via steam gelierator ,

blowdown. >

c) Error in amount of dilution water used during the reporting period.
