CALVERT CLIFFS NUCLEAR POWER FIANT EFF111ENT AND WASTE DISPOSAL SEMI-ANNUAL REPORT SUPPLEMENTAL INFORMATION Facility - Calvert Cliffs Nuclesr Power Plant Licensee - Baltimore Gas & Electric Company I. REGUIATORY LIMITS A. Fission and Activation Cases

1. The instantaneous release rate of noble gases in gaseous effluents shall not result in a site boundary dose rate greater than 500 mrem / year to the whole body or greater than 3000 arem/ year to the skin.
2. Caseous Radwaste Treatment System and the Ventilation Ex-haust Treatment System shall be used to reduce gaseous emis-sions when the calculated gamma dose due to gaseous effluents exceeds 1.20 mrad or the calculated beta dose due to gaseous effluents exceeds 2.40 mrad at the site boundary in a 92 day period.

4. All of the above parameters are calculated according to the methodology specified in the Offsite Dose Calculation Manual  ;

(ODCM).  !

B. Iodines and Particulates with Half Lives Greater than Eight Days

1. The instantaneous release rate of Iodines and particulates in gaseous effluents shall not result in a site boundary j dose in excess of 1500 arem/ year to any organ. L
2. The Caseous Radwaste Treatment System and the Ventilation Exhaust Treatment System shall be used to reduce radioactive materials in gaseous effluents when calculated doses exceed 1.8 arem to any organ in a 92 day period at the site bounda.

3. The dose to a member of the public at the site boundary from Iodine 131 and particulates with half lives greater than eight days in gaseous effluents shall no'; excoed:

15 mrem to any organ per quarter 30 mrem to any organ per year i less than .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 che ODCM.

C. Liould Effluents

1. The concentrations of radioactive isotopes in liquid effluents from the plant shall not exceed the values speci-fied in 10 CFR, Part 20, Appendix B, for unrestricted areas.
2. The liquid radwaste treatment system shall be used to reduce the radioactive isotopes in liquid effluents from the plant +

when the calculated doses to unrestricted areas exceed 0.36 arem to the whole body, or 1.20 mtem to any organ in a 92 i day period.

3. The dose to a member of the public in unrestricted areas shall not exceed * ,

3 mrem whole body dose por quarter  ;

i 10 mrem dose to any organ per quarter 6 mrem whole body. dose per year  ;

20 mrem dose to any organ per year  !

4. All of the liquid dose paraseters are calculated according -

to the methodology specified in the ODCM.

II. MAXINUN . PERMISSAB12 CONCENTRATIONS A. Fission and Activation Cases Prior to the batch release of gaseous effluents, the gas gamma activities are sumned. If the total does not exceed the dose rate limitations for the most limiting isotope, then the batch is ,

released. If the most limiting isotope criteria is not met, then i a detailed dose rate calculation is performed as described in the ODCM.

l B. Iodines and Particulates with Half Lives Greater than Eight Days l

l l

Compliance to the dose rate limitations from Iodines and particu-lates is demonstrated by calculating the maximum quantity that could be seen on a weekly sample. This is reduced by a factor of 0.5 for conservatism. As long as the 1-131 (most limiting iso.

tope) reles.ses in a seven day period do not exceed 12.5 Ci, then l

no further analyses are needed to verify compliance without ex-ceeding the limits of 1.B.3.

C. L!auid Effluents The MPCs used for radioactive materials released in liquid 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.

III. TECHNICAL SPECIFICATION REPORTING REQUIREMENTS (Section 6.9.1.8)

A. Previous Calendar Year (1987) Dose Assessment Summarv

! During 1987 liquid releases from Calvert Cliffs resulted in a l l

maximum organ dose of 0.80 mrem and a maximum whole body dose of e 0.085 mrem. This was less than 5% of the allowable yearly Tech- '

nical Specification organ dose limit and less than 2% of the al.

lowable yearly Technical Specification whole body dose limit.

This dose was calculated using ODCM methodology (Adult Fish and Shellfish Pathways). The Castro Intestinal Tract was the maximum l organ dose pathway.

Caseous Noble Gas Releases resulted in a maximum of 0.13 mrad I

gamma and 0.35 mrad beta exposure. Particulate releases from Calvert Cliffs resulted in a maximum organ exposure of 0.44 mrem via the Thyroid Pathway. These doses were calculated using ODCM  !

methodology. All gaseous release pathways were below 2% of their '

allowable Technical Specification limits for 1987.

B. 40 CFR 190 Total Dose Como11aDR1 i l

Based upon the releases for the first half of 1988 and the ODCM calculations, the maximum exposed individual would receive less l 1% of the allowable dose. This does not include the direct radiation contribution which did not show a statistical '

l difference greater than the normal background. A more detailed '

I evaluation will be conducted for the entire year in the next ,

j semi annual report. l i

C. Solid Vaste Report Reauirements During the first half of 1988, the only type of radioactive solid waste shipped from Calvert Cliffs was radioactive resin, which was dewatered and shipped in high integrity containers.

D. ODCM and PCP Chanzes g

No changes were made in the first half af 1988.

IV. AVERACE ENPRbY Not Applicable V. MEASUREMENTS AND APPROXIMATIONS Alm TOTAL RADI0 ACTIVITY l A. Fission and Activation Cases

1. Batch Releases Prior to each batch release of gas from a pressurized gas decay tank, a sample is collected and analyzed for each sig-nificant gaseous isotope using a Ce detector. The total ac-tivity released is based on the pressure / volume relationship (gas laws) of the tank.

Prior to and af ter the release of gas as a result of purging containment, samples are collected and analyzed for each significant gaseous isotope using a Ce detector. The total activity released is based on containment volume and purge rate. Activity buildup while purging is also considered.

2. Continuous Releases During the release of gas from the main vents, samples are collected and analyzed at least weekly for each significant gaseous isotope using a Ge detector. The total activity re-leased 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 The total act.ivity released from a pressurized gas decay tank, containment purges and containment vents as Iodines and particulates is accounted for by the main vent Iodine and particulate continuous samples.

t ,

2. Continuous Releases buring 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 gamma isotope using a Ge detector. The total activity released for the week is based on the total sample activity found on the fil -

ters decay corrected to the midpoint of the sample period and multiplied by the main vent flow for the week. These weekly particulate filters are then composited to form monthly and quarterly composites at which time gross alpha and strontium 89 and 90 are analyzed.

C. Liauld Effluents

1. Batch Releases Prior to the release of liquid from a vaste tank, a sample is collected and analyzed for the concentration of each sig-nificant gamma energy radionuclide 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 re-leased 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 use in analyses of gross alpha, strontium 89 and 90, and tritium.

When steam generator blowdown is discharged to the circulat-ing 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 ana.

lyzed for each significant isotope using a Ge detector and these results are multiplied by the actual qui.,tity of blowdown to determine the total activity released. The weekly composite is also used to prepare monthly and quar-terly composites for use in analyses of tritium, gross alpha, and strontium 89 and 90.

2. Continuous Releases None 5

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 addi-tion to the random error, the detector to sample geometry system-atic error during gamma counting was determined. This included an estimate of sample volume error and samp*e pipetting error.

More specifically the following other systematic errors were also j examined:

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

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

c) Error in amount of dilution water used during the re-porting period.

l 2. Gases I

a) Error in main vent release flow.

b) Error in sample flow rate.

2 c) Error in containment purge release flow.

l d) Error in gas decay tank pressure.

I

Where errors could be estimated they are usually considered additive.
