CALVERT CLIFFS NUCLEAR POWER PLANT EFFLUENT AND WASTE DISPOSAL 2001 ANNUAL REPORT SUPPLEMENTAL INFORMATION C. Liquid Effluents

1. The concentrations of radionuclides in liquid effluents from the plant shall not exceed the values specified in 10 CFR Part 20, Appendix B, Table II, Column 2 for unrestricted areas (ODCM 3.11.1.1).
2. The liquid radwaste treatment system shall be used to reduce the concentration of radionuclides in liquid effluents from the plant when the calculated dose to unrestricted areas exceeds 0.36 mRem to the whole body, or 1.20 mRem to any organ in a 92 day period (ODCM 3.11.1.3).

3 mRem/qtr, total body 10 mRem/qtr, any organ 6 mRem/year, total body 20 mRem/year, any organ

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

I. MAXIMUM PERMISSIBLE CONCENTRATIONS A. Fission and Activation 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 ODCM 3.11.2.1 are not exceeded.

B. Iodines and Particulates with Half Lives Greater than Eight 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 charcoal samples are analyzed by gamma spectroscopy for quantification of radioiodines. The particulate samples are analyzed by gamma spectroscopy for quantification of particulate radioactive material. All of the above parameters are calculated according to the methodology specified in the ODCM.

C. Liquid Effluents The Maximum Permissible Concentrations (MPCs) used for radioactive materials released in liquid effluents are in accordance with ODCM 3.11.1.1 and the values from 10 CFR Part 20, Appendix B, Table II, Column 2 including applicable table notes. In all cases, the more restrictive (lower) MPC found for each radionuclide is used regardless of solubility.

1. 2001 Dose Assessment Summary Actual Percent of ODCM Value ODCM limit Limit Liquid Waste:

Maximum Annual Organ Dose (mRem)' 0.43 2.2% 20 Maximum Whole Body Dose (mRem) 0.005 0.08% 6 Gaseous Waste:

Noble Gases:

Maximum Quarterly Gamma Air Dose (mRad) 0.001 0.01% 10 Maximum Quarterly Beta Air Dose (mRad) 0.004 0.02% 20 Iodines and Particulates:

Maximum Annual Organ Dose (mRem) 2 0.035 0.12% 30 The controlling pathway was the fish and shellfish pathway with adult as the controlling age group and the gastrointestinal tract representing the organ with the highest calculated dose during the calendar year of 2001.

2 The controlling pathway was the child-infant-thyroid pathway representing the organ with the highest calculated dose during the calendar year of 2001. There is currently no known milk pathway in existence.

2. 40 CFR 190 Total Dose Compliance Based upon the calendar year 2001 and the ODCM calculations, the maximum exposed individual would receive less than 1% of the allowable dose. During the calendar year 2001, there were no on-site sources of direct radiation that would have contributed to a significant or measurable off-site dose. The direct radiation contribution is measured by both on-site and off-site thermoluminescent dosimeters (TLDs). The results of these measurements did not indicate any statistical increase in the off-site radiation doses attributable to on-site sources. Therefore, no increase in the calculated offsite dose is attributed to the direct exposure from on-site sources. A more detailed evaluation will be reported in the Annual Radiological Environmental Operating Report.
3. Solid Waste Report Requirements During 2001, the types of radioactive solid waste shipped from Calvert Cliffs were dry compressible waste, filters, and dewatered resins which were shipped in High Integrity Containers (HICs) within NRC approved casks, Sealand containers, and steel boxes. Appendix A provides a detailed breakdown of the waste shipments for 2001 per the categories specified in Technical Specification 5.6.3. At CCNPP, methods of waste and materials segregation are used to reduce the volume of solid waste shipped offsite for processing, volume reduction and burial.

4. Offsite Dose Calculation Manual (ODCM) and Process Control Program (PCP)

Changes The ODCM was revised on May 14, 2001, a copy is attached. There were no changes to the PCP.

B. Radioactive Effluent Monitoring Instrumentation One effluent pathway was unmonitored for more than 30 consecutive days in 2001. The radiation monitor designated 0-RE-2201, Liquid Radwaste Discharge Radiation Monitor, was out of service from 11 -May-2001 until 5-August-200 1. A large amount of activity was introduced into the liquid radwaste system in April 2001. To reduce the activity, the liquid was recirculated through filters. This flow path included the radiation monitor's sample chamber. Filtration continued for an extended period of time. Although the activity in the radwaste system was reduced significantly, the radiation monitor became contaminated in May, causing elevated background on the radiation monitor. Due to the high "background" on the radiation monitor, it was taken out-of-service. Because filtering radwaste tanks continued, the radiation monitor could not be removed from service and decontaminated.

Once the radiation monitor could be decontaminated, maintenance was performed to reduce background contamination. The internal surface of the radiation monitor's sample chamber was machined to remove fixed contamination. Following machining, an epoxy coating was applied to the internal surface to reduce the possibility of recontamination.

C. Independent Spent Fuel Storage Installation (ISFSI), ISFSI Technical Specification 6.1 No (0) casks of spent fuel were transferred to the 1SFSI during 2001. No quantity of radionuclides was released to the environment during the ISFSI operation in 2001.

Additional information regarding the ISFSI radiation-monitoring program is included in the Annual Radiological Environmental Operation Report.

IV. AVERAGE ENERGY Not Applicable.

V. MEASUREMENTS AND APPROXIMATIONS AND TOTAL RADIOACTIVITY A. Fission and Activation Gases

1. Batch Releases Prior to each batch release of gas from a pressurized waste gas decay tank or containment, 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).

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 sample time multiplied by the main vent flow for the week.

4

CALVERT CLIFFS NUCLEAR POWER PLANT EFFLUENT AND WASTE DISPOSAL 2001 ANNUAL REPORT SUPPLEMENTAL INFORMATION Prior to and after each 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.

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 the sample analysis and the main vent flow.

B. Iodine and Particulates

1. Batch Releases The total activities of radioiodines and particulates released from pressurized waste gas decay tanks, 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. 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 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. The weekly particulate filters are then composited to form monthly and quarterly composites for the gross alpha and strontium-89 and strontium-90 analyses.

C. Liquid Effluents I1. 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 emitting 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 from each release, this is used in turn to prepare monthly tritium and quarterly gross alpha, iron-55, strontium-89, and strontium-90 samples for analysis.

2. Continuous Releases To account for activity from 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.

5

CALVERT CLIFFS NUCLEAR POWER PLANT EFFLUENT AND WASTE DISPOSAL 2001 ANNUAL REPORT SUPPLEMENTAL INFORMATION When steam generator blowdown is discharged to the circulating water conduits, it is sampled at a minimum of three times per week and these samples are used in turn to prepare a weekly blowdown composite sample based on each day's blowdown. The weekly composite sample 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 composites for tritium analysis.

During periods of primary-to-secondary leakage, the secondary system becomes contaminated and subsequently, contaminates the Turbine Building sumps. The low level activity water (predominantly tritium) contained in the Turbine Building sumps is (from 1-Jan-01 thru 14-May-01) released directly to the Chesapeake Bay or is discharged to the circulating water conduits (after 14-May-01). This water is sampled weekly and composited. The composite sample is analyzed at least monthly for tritium and principal gamma emitting radionuclides. The results are multiplied by the actual quantity of liquid released to determine the total activity released.

D. Estimation of Total Error Total error for all releases was estimated using, as a minimum, the random counting error associated with typical releases. In addition to this random error, the following systematic errors were also examined:

1. Liquid
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 containment purge release flow.
d. Error in gas decay tank pressure.

Where errors could be estimated they are usually considered additive.
