SUPPLEMENTAL INFORMATION Facility - Calvert Cliffs Nuclear Power Plant Licensee - Baltimore Gas & Electric Company I. REGULATORY LIMITS A. Fission and Activation Gases:

1. The instantaneous release rate of gross activity, except for I-131 and particulates with half-lives longer than eight days shall not exceed Qi gg 5

(3.85 x 10 ) (MPC)i where Qi is the release rate in Ci/sec for isotope i and MPCi is the maximum permissible concentration of isotope i as defined in Appendix B, Table II, Column 1,10 CFR 20.

2. The release rates of gross gaseous activity shall not exceed 16 percent of the values specified in I.A.I. above when averaged over any calendar quarter. See Table IA, A3.
3. The release rates of gross gaseous activity shall not exceed 8 percent of the values specified in I.A.I. above when averaged over 12 consecutive months. See Table 1A, Ate.

)

1]. Submitted in accordance with Section 5.6.1.b of Appendix B of the Environmental Technical Specifications 1

j

B. Iodines and Particulates, Half-Lives >3 Days:

1. The release rate from the main vents of I-131 and particulates with half-lives greater than eight days released to the environment as part of airborne effluents shall not exceed 2.0 uCi/sec.
2. The release rates of I-131 and particulates shall not exceed 8 percent of the value specified in I.B.1, above when averaged over any calendar quarter. See Table 1A, B3.
3. It should be noted that " iodines" as used here includes only iodine-131 since the Technical Specifications only refer to it specifically. Such other iodines, i.e., iodine-133, iodine-135, etc., are treated as gross activity and are included in I.A.1. and I.A.2.
4. The release rates of I-131 and particulates shall not exceed 4 percent of the values specified in I.B.1 above when averaged over any 12 consecutive months. See Table 1A, B4.

C. Liquid Effluents:

1. The release rate of radioactive liquid effluents, excluding tritium and noble gases, shali not exceed 10 curies per unit during any calendar quarter.
2. The radioactivity release concentrations in liquid effluents from the plant shall not exceed the values specified in 10 CFR, Part 20, Appendix B, for unrestricted areas.

II. MAXIMUM PERMISSIBLE CONCENTRATIONS The MPC's used for radioative materials released in liquid and gaseous effluents are in accordance with Technical Specifications and/or are derived from the use of notes to Appendix B,10 CFR, Part 20. In all cases, the most restrictive (lowest)

MPC found for each isotope is used regardless of solubility.

The following limits were used to calculate the percent of applicable limit in Table 2A:

A. Fission and Activation Products - Limit used 1 x 10-7 uCi/ml. This limit was used as given in the notes to Appendix B, Table II, Column 2 of 10 CFR 20.

B. Tritium - Limit used 3 x 10-3 uCi/ml.

This limit was used as given in Appendix B, Table II, Column 2 of 10 CFR 20.

C. Dissolved and Entrained Gases - Limit used 3 x 10-6 uCi/ml.

This limit was used as given in Appendix B, Table II, Column 2 of 10 CFR 20.

III.- AVERAGE ENERGY - not applicable IV. MEASUREMENTS AND APPROXIMATIONS OF TOTAL RADIOACTIVITY 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 for each significant isotope using a Ge(LI) detector. The total activity released is based on the pressure / volume relationship (gas laws) of the tank prior to and af ter the i

release. ,

Prior to and after the release of gas as a result of purging containment, samples are collected and analyzed for each significant isotope using a Ge(Li) detector. The total activity released is based on containment volume and purge rate with activity buildup while purging is being considered.

2. Continuous releases During the release of gas from the main vents, samples are collected and analyzed at least weekly for each significant isotope using a Ge(Li) detector. The total activity released for the week is based on the total sample activity decay corrected to the midpoint of the sample period and multiplied by the main vent flow for the week.

B. Iodine and Particulates:

1.- Batch releases Total activity released from a pressurized gas decay tank as iodines and particulates is measured by the same methods as fission and activation gases.

Prior to and af ter the release of gas as a result of purging containment, lodines are sampled using a charcoal filter and particulates are sampled using a particulate filter. These filters are analyzed for each significant isotope using a Ge(LI) detector. The total activity released is based on containment volume and purge rate with activity buildup while purging is being considered.

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 for each significant isotope using a Ge(Li) detector. The total activity released for the week is based on the activity found on the filters multiplied by the main vent flow for the week. The activity on the filters is corrected for decay and buildup during the sample period. These weekly particulate filters are then compo ited to form monthly and quarterly composites at which time gross alpha and strontium 89 and 90 are analyzed.

C. Liquid Effluents:

1. Batch releases Prior to the release of liquid from a monitor tank, a sample is collected and analyzed for the concentration of each significant gamma energy peak to demonstrate compliance with Section I.C.1 above using the water flow rate in each discharge conduit into which the effluent is discharged at the time of discharge. The total activity released in each batch is determined by multiplying the volume released times the concentration of each isotope. 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 week's releases, and this is used in turn to prepare nionthly and quarterly composites for use in analyses of gross alpha and strontium 89 and 90.
2. Continuous releases Steam generator blowdown is sampled daily and these samples are used

. ;,_ in turn to prepare a weekly blowdown composite based on each day's g

blowdown. The weekly composite is analyzed for each significant isotope using a Ge(LI) detector and these results are multiplied by the actual quantity of blowdown to determine the total activity released. The I

weekly composite is also used to prepare monthly and quarterly composites for use in analyses of tritium, gross alpha, and strontium 89 and 90.

y, x _ _

D. Estimation of Total Error:

Total error on all releases was estimated using as a minimum the random counting error associated with typical releases. In addition to the random error, the detector to sample geometry systematic error during gamma counting was determined. This included an estimate of sample volume error and sample pipetting error. More specifically the following other 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 were usually considered additive.
