EFFLUENT AND WASTE DISPOSAL SE4I-ANNUAL REPORT]

SUPPLHEITAL I?TFCF14ATION Facility - Calvert Cliffs Nuclear Power Plant Licensee - Baltimore Gas & Electric Cenpany 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 Oi g

-1

, (3.85 x 105) (leC)1 where Qi is the release rate in Ci/see for isotope 'i and MFCi is the =aximum 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.1. above when averaged over any calendar quarter. See Table 1A, A3.
3. The release rates of gross gaseous activity shall not exceed 8 percent of the values specified in I. A.1. above when averaged over 12 consecutive months. See Table IA, Ah.

B. Iodines and Particulates, Half-Lives > 8 Days:

1. The release rate from the main vents of I-131 and particulates vith half-lives greater than eight days released to the environs lj Submitted in accordance with Technical Specification 5.6.1.b. . , .

i as part of airborne effluents shall not exceed 2.0 uCi/sec (I-131 equivalent).

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, 33

~

3 It should be noted that " iodines" as used here includes only iodine-131 since the technical specifications caly 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 1.A.2.

h. The release rates of I-131 and particulates shall not exceed h percent of the values specified in I.B.1. above when. averaged over any 12 consecutive months. See Table 1A, Bh.

C. Liquid Effluents:

1. The release rate of radioactive liquid effluents, excluding tritium and noble gases, shall not exceed 10 curies per unit during any calendar quarter.
2. The radioactivity release concentrations in liquid effluents frca 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 radioactive =aterials released in liquid and gaseous effluents are in accordance with Technical Specifications and/or are derived from the use of notes to Appendix 3,10 CFR Part 20. In - . -

all cases the most restrictive (lovest) MFC 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-I uCi/=1.

This li=it was used as given in the notes to Appendix B,10 CFR 20.

B. Tritium - Li=it used 3 x 10-3 uC1/=1.

This l'imit was used as given in Appendix 3, Table II, Colu=n 2 of 10 CFR 20.

C. Dissolved and Entrained Gases - Li=it used 3 x 10-6 uCi/=1.

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

III. AVERAGE EIERGY - not applicable IV. MEASUREMENTS AITD APPROXIMATIONS OF TOTAL RADI0 ACTIVITY A. Fission and Activation Gases:

1. Batch releases Prier to each batch release of gas from a pressurized gas decay tank, a sa=ple is collected and analyzed for each significant isotope using a Ge(L1) detector. The total activity released is based on the pressure /volu=e relationship (gas lavs) of the tank prior to and after the release.

Prior to and after the release of gas as a result of purging containment, sa=ples are collected and analyzed for each significant isotope using a Ge(Li) detector. The total , ,

activity released is based on containment volu=e and purge rate with activity buildup while purging being considered.

2. Continuous releases During the release of gas from the main vents, sa=ples 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 weekly result multiplied by the main vent flow for the week.

B. Iodines and Particulates:

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

Prior to and after the release of gas as a result of purging containment, iodines are sampled using a charecal 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 volune and purge rate with activity buildup while purging being considered.

2. Continuous releases During the release of gas from the main vents, samples of iodines and particulates are collected using a chared end 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 r:ultiplied by the mai'n vent flov for the week. - The activity on the filters

is corrected for decay and buildup during the sa=pling period.

These weekly particulate filters are then composited to for=

onthly and quarterly ec=posites at which time gross alpha and strontium 89 and 90 are analyzed.

Total activity released via condenser vacuum pu=p releases

~

is measured by the same methods e= ployed for fission and activation gases.

C. Liquid Effluents:

1. Batch releases Prior to the release of liquid frc= a monitor tank, a sa=ple is collected and analyzed for the concentration of each significant ga==a energy peak to demonstrate co=pliance with Section 1.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 deternined by multiplying the volu=e released times the concentration of each' isotope. The actual volume released is based en the difference in tank levels prior to and after the release. A proportional ec=posite sa=ple is also withdrawn for each week's releases, and this is used in turn to prepare monthly and' quarterly co=posites for use in analyses of gross ,

alpha and strontium 89 and 90.

2. Contir.uous releases Steam generator blevdown is sa= pled daily and these samples are used in turn to prepare a weekly blovdown composite based

- on each day's blevdown. The weekly ec=posite is analyzed for

each significant isotope using a Ge(Li) detector and these results are multiplied by the actual quantity of blevdown to deter =ine the total activity released. The weekly ec=posite is also used to prepare monthly and quarterly ecmposites for use in analyses of tritium, gross alpha, and strontium 89 and 90.

~

D. Estimation of Total Error:

Total error on all releases was esti=ated using as a =inimu=

the randes counting error associated with typical releases. In addition to the random error the detector to sample gecnetry systematic error during gn==a counting was determined. This included an estimate of sa=ple volu=e error and sample pipetting error. More specifically the following other systematic errors vere also examined:

1. Licuid -
a. Error in volume of liquid released prior to dilution during batch releases.
b. Error in volune of liquid released via steam generator blevdown.
c. Error in amount of dilution water used during the reporting period.
2. Gases
a. Error in main vent release flow,
b. Error in sa=ple flow rate.
c. Error in containment purge release flow.
d. Error in gas decay tank pressure.

Where errors could be esti=ated they were usually considered additive.
