INTRODUCTION TheOFFSITEDOSECALCULATIONManualisasupportIngdocumentofthe RADIOLOGICAL EF11UENT TECINICAL SPECIFICATIONS. As such the ODCM describes the methodology and paroneters to be used in the calculation of offsite doses due to radioactive liquid and gaseous effluents and in the calculation of liquid and gaseous effluent monitoring instrumentation alarm / trip setpoints. The ODCM contains a list and graphical description of the specific sample locations for the radiological environmental monitoring program. Minimum OPERABLE configurations of the liquid and gaseous radwaste treatment systems are shown in Figures 1.4 and 2.1.

/

The ODCM will be a41ntained at the plant for use as a reference guide and training document of accepted methodologies and calculations. Changes in the calculation methods or parameters will be incorporated into the ODCM in order to assure th'at the ODCM represents the present methodology in all applicable areas.

g, Offsite dose calculations utilized to implement the RADIOLOGICAL EFFLUENT TECHNICAL SPECIFICATIONS shall normally be performed with the RM-21 Report Processor. The RM-21 software utilizes NUREG-0133 (October 1978) dose calculation methodology. The methodology described in the ODCM shall be d ne a manual backup to the RM-21.

SECTION 1.0 LIQUID EFFLUENTS The Comanche Peak Steam Electric Station, Units 1 and 2, is located on the Squaw Creek Reservoir which is a point of supply and discharge for the plant circulating water. Liquid releases are made via the Circulating Water Discharge Canal. Discharge pathwayr for the liquid radwaste sources are shown in the diagram of Figure 1.1.

Although no significant releases of radioactivity are expected frem the General Service Water System, this effluent pathway is monitored as a precautionary measure.

1.1 GENERAL METHODOLOGY FOR DETERMINING LIQUID EFFLUENT MONITOR SETPOINTS Normal liquid releases from the radwaste system will originate from the laundry holdup tanks and waste monitor tanks and terminate in Squaw Creek Reservoir. To ensure arch discharges do not exceed the limits of 10CFR20, Appendix B. Table II, Column 2 at the release point to the unrestricted area, an in-line radiation detector monitors discharges to the circulating water discharge canal.

X-RV-5253 is the isolation valve controlled by detector X-RE-5253.

The isolation valve shuts automatically if the detector alarms or is placed out of service. The methodology for determinir.g the setpoint for detector X-RE-5253 is as follows:

1.1.1 Isotopic Concentration of the Waste Tank Determine the isotopic concentration of the waste tank to be released:

IC = IC + (C,+ C, + C + C,)

g t

p i

g IC = Sum of the batch radioactive concentrations (gCi/ml) f i

I IC = Sum of the concentrations of each measured gamma 8

g emitter (qCi/ml)

C = concentration of alpha emitters as measured in the monthly I

composite sample.

(Sample analyzed for gross alpha only)

(gCi/ml)

I C = concentration of Sr-89 and Sr-90 as measured in the quarterly 8

composite sample (qCi/ml)

C = concentration of H-3 as measured.in the monthly composite I

rample (gCi/ml)

C = concentration of Fe-55 as measured in the quarterly composite Fe sample (qCi/ml) 1.1.2 Maximum Effluent Flow Rate (f)

The effluent discharge rate is determined from the number of pumps running and their capacity. The radwaste_ system is comprised of the following pumps:

Laundry Holdup and Monitor Tank - 100 gpm Waste Monitor Tank Pump #1

- 100 gpm Waste Monitor Tank Pump #2

- 100 gpm I

mf' l

I l-2 LI

g I

Normally, only one waste taok will be pumped at a time. XRE-5253 is an in-line process monitor which only allows 46 gpm to flow past it.

As a worst case condition, the effluent flow rate (f) will be determined as the capacity of ose tank being pumped. This built in safety factor of 2.2 ensures that the effluent flow rate fs not being underestimated. This n.aximum effluent flow rate of 100 gpm will be used in the calculation of dilution factor for all liquid radwaste system batch discharges.

1.1.3 Dilution of Liquid Effluents Due to Circulating Water Flow (F)

Since liquid effluent from the radwaste treatment system is mixed with circulating water prior to being returned to Squaw Creek Reservoir, the setpoint for detector X-RE-5253 is a function of the circulating water flow rate. The total circulating water flow rate per plant is 1.1 million gpm. This is determined from the l

Ingersoll-Rand pump curves (Fig. 1.3) which indicate a flow rate per pump of 275,000 gpm.

F(diluting flow) = (275,000 gpm/ pump) x (f of pumps) x SF Where: SF = Stfety Factor of (.9).

This compensates for flow fluctuations from the rate predicted by the circulating water pump curves (Fig. 1.3).

lI lI 1.1.4 Actual Dilution Factor (ADF)

ADF is the ratio of the effluent flow rate plus the circulating water flow rate divided by the effluent flow rate.

ADF = (f + F)/f i

l Where:

f = 100 gpm l

l F = (275,000 gpm/ pump) x (# of pumps) x SF (.9) 1.1.5 Required Dilution Factor (RDF) i The required dilution factor ensures that the isotopic l

l concentrations expressed in 10CFR20, Appendix B Table II, Column 2 l

are not exceeded during a discharge.

MFC,' = Maximum Pettr.issible Concentration of Radionuclide i SF = Safety Factor of 2 i

NOTE: If RDF is less than 1, the tank effluent meets discharge limits without dilution. Detector, X-RE-5253, would l

then be set in accordance with Eq. I below with RFD set equal to 1.

As a further consideration, the reservoir into which the diluted radwaste flows may build up a concentration of radioactive isotcpes.

It is therefore necessary to account for recirculation of previously discharged radionuclides. This is accomplished as follows:

Eq. 2 F' = FT1 - I (C{/MPC ))

i F' = Adjusted Circulating Water Flow Rate C{ = Radionuclide Concentration of the Reservoir MPC = Maximum Permissible Concentration of Radionuclide i f

F = (275,000 gpm/ pump) x (# of pumps) x SF x AF NOTE:

IfCjislessLLDthenF'=Fandnoadjustedflowrate need be considered in the calculation of ADF. LLD is the smallest concentration of radioactive material in a sample that will be detected with a 95% probabflity.

I When considering the mixture of nuclides in the liquid effluent stream in terms'of detector sensitivity, the most probable nuclides present would be those referenced in Technical Specifications 3/4.11.1.1.

Figure 1.2 is a representative energy spectrum response for the RD-33 type detector used in XRE-5253. This curve illustrates that for any given mixture of the most probable nuclides the conversion factor between counts per minute and

present, nicrocuries per al remains relatively constant. In fact between I

1-5 I

t lI I

Cs-137 and co-60, the total change in sensitivity is approximately 7%.

Because this is well within the accuracy of measurement, there l

is no need to change the software sensitivity for given varied i

effluent concentrations. However, should the concentration of lI previously unexpected nuclides become significant, further il.

evaluation would be required.

Concentration of radioactivity in this effluent line normally is expected to be insignificant. Therefore, the monitor setpoint should be established as close to background as practical to prevent spurious alarms and yet alarm should an inadvertent release occur.

To this end, the background multiple will be three (3) [i.e.,

setpoint will be initially established at three times background until further data can be collected). If this effhent stream should become contaminated with radioactivity, radienuclide concentrations must be determined and a radiation monitor setpoint determined as follows:

1.4 Turbine Building Sump Effluent Radiation Monitor 1RE-5100 The purpose of the detector for the turbine building sumps is to monitor discharges and divert the turbine building sumps f rom the Low Volume Waste Pond to the Waste Water Holdup Tanks if they become radioactive. Because the only sources to the sump effluent are from the secondary steam system, activity is expected in the turbine building sump effluent only if a significant primary-to-secondary leak is present. Since only non-radioactive turbine building sump water is allowed to go to the Lcw Volume Waste Pond, the monitor setpoint should be established as close to background as practical to prevent spurious alarms and yet alarm should an inadvertent radioactive release occur. To this end, the background multiple will be three (3)

[i.e., setpoint will be initially established at three times background until further data can be collected]. Then, if this setpoint is exceeded, 1RE-5100 will direct valves 1RV-5100A and B to divert the turbine building sumps to the Waste Water Holdup Tanks where they can then be sampled and releaced to Squaw Creek Reservoir per 10 CFR 20 limits.

That is, setpoint adjustments are not required to be made if the existing setpoint level corresponds to a lower count rate than the calculated value. Setpointo may be established at values lower than the calculated values if desired, t-If a calculated setpoint is less than the monitor reading associated I with the particular release pathway, no release may be made. Under such circumstances, contributing source terms may be reduced and the setpoint recalculated. I At CPSES, all gaseous effluents are released to the atmosphere through the two Plant Vent Stacks (Figure 2.1). Setpoint methodology for the noble gas monitors associated wich the plant .
