1 l- 11. STAXIhf Uht PERhtISSillLE CONCENTRATIONS l

A. Fission and Activation Gases Prior to the batch release of gaseous efnuents, a sample of the source is collected and L 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 Specificatian 3/4.11.2.1 are not exceeded.

B. Todines and Particulates with Half Lives Greater than Eicht Days 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 chrecal samples are analyzed by gamma spectroscopy for quantification of any release of rediciodines. The particulate samples are analyzed by gamma spectroscopy for quantification of particulate radioactive material. Based on guidance provided in the ODChi, compliance with dose rate limits for the 2

i.

radiciodines and particulates may be based on a comparison of the actual measured release quantity over a sample period with a pre-estelished upper bound.

C. Liguid Efuuents 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 moic restrictive (lower) MPC found for each radionuclide is used regardless of solubility.

V. hjEASUltEMENTS AND APPitOXIMATIONS AND TOTAL 1(ADIOACTIVITY A. Fission 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 Germanium (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 et 4 containment purge, a gas 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 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. Iodine and Particulates 1, Batch Releases -

The total activities of radiciodines 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.

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

Tk 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 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. These weekly particulate filters are tLen composited to form monthly and quarterly composites for the gross alpha and strontium 89 and 90 analyses.

.Ae C. Liauid Efiluents

1. Batch Releases Prior to the release of liquid from a waste tank, a sample is collected and analyzed by gamma spectroscopy for the principal gamma emiiting radionuclides. To demonstrate compliance with the requirements addressed in Section I.C.1 above, the measured radionuclide -concentrations are compared with the allowable MPCs; dilution in the discharge conduit is considered, and an allowable release rate is verified.

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 ine gross alpha, strontium 89 and 90, and tritium analyses.

2. Continuous Releases Prior to discharge of any continuous releases, a sample is collected and analyzed - by gamma spectroscopy for the principal gamma emitting radionuclides. The measured radionuclide concentrations are compared with the allowable MPC concentrations in the discharge conduit, and an allowable release rate is verified.

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 blowdown. The weekly

_ composite 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 prepare monthly and quarterly composites for tritium, gross alpha, and si:7ntium 89 and 90 analyses.

l -During primary to secondary leakage, the secondary system becomes

= contaminated and subsequently, contaminates the turbine plant sumps. This low level activity (mostly tritium) water is released directly to the Chesapeake

' Bay. This water is sampled at least weekly and composited. These samples are added to a composite based on the amount released during that week.

The composite sample is analyzed monthly for tritium and for the principal gamma emitting radionuclides. The results are multiplied by the actual l quantity of liquid released to determine the total activity released. His composite is used to prepare quarterly samples for strontium 89 and 90 analyses.

kr D. limt!Lation of Total Error Total error on all releases was estimated using as a minimum the random counting error associated with typical teleases. In addition to this random error the following i systematic errors were also examined:

1. L! quid a) Error in volume of liquid released prior to dilution during batch releases.

b) Error in volume of liquid released via steam generator blowdown.

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

2. Gases a) Error in main vent release flow, b) Error in sample flow rate.

c) Error in contalnment purge 2.ase .L,w.

d) Enor in gas decay tank pressure.

Where errors could be estimated they are usually considered additive.

SUMMARY

OF CIIANGES TO TIIE CCNPP ODCM FIRST IIALF 1992 CllANGES TO Tile CCNPP ODCM IN FilGT llALF 1992

SUMMARY

AND llASIS The Calvert Cliffs Offsite Dose Calculation Manual (ODCM) is contained in the Chemistry I Procedure CP 607. Changes to this document are controlled through the ncrmal procedure change review and approval process. This pro ess meets the requirements of CCNPP Technical Specification 6.17. ,

1

- One change was made to the ODCM during the first 1.alf of the year 1992. The change was tes icwed by the Plant Operations and Safety Review Committee (POSitC) and approved by the Plant General Manager, Calvert Cliffs Nuclear Power Plant, prior to implementation. Change bars are provided in the right margin of the ODCM text to identify the changes made.

l The change was approved on April 10,1992, and designated as change 92-027. The change revised l the values for t'ic Unit 1 and Unit 2 main vent stack flow r ates. 'Ihc revised values of main vent stack flow rates are based on ar*nal measurernents obtahed during a 2. year period. 'Ihe measurements I

were made using approvec Engineering and Test Procedures. I l

CP-607 Page 13 of 27 3.2.5 All iodines and particulate gamma emitters discharged from the plant shall be accounted for with the continuous main vent header samples since all gaseous effluents are discharged via this path.

3.2.6 A gaseous waste discharge permit shall be prepared for bath releases to document release conditions and approvals, sample analysis results and compliance with Technical Specifications.

3.2.7 Credit shall be taken for main vent dilution from the reactor -

unit through which a release is conducted.

3 Unit 1 - Main Vent Flow - 59.4 m /sec- lPCR 3

Unit _.2 - Main Vent Flow - 47.1 m /sec-l92-l027 3.3 Gaseous Effluent Dose Rate 3.3,1: Site Boundary Dose Rate (Total Body, Skin)

Technical Specification 3.11.2.la limits the dose rate at the '

site boundary due to noble gas releases to s 500 mrem /yr, total body s 3000 mrem /yr, skin. If any of these are exceeded, lPMF review 40CFR302 to determine if a Reportable Quantity limit l90-102 has been exceeded. (3758) Radiation monitor alarm setpoints l

~

are established to assure that these release limits are not l exceeded. In the event any gaseous releases from the station results in the alarm setpoints being exceeded, an evaluation of the unrestricted area dose rate resulting from the release may be performed using the following equations:

btb - X/Q x (I X$xQ) $

bs - X/Q x (I L$ + 1.1 M 4) x Q$

Where:
