TheOFFSITEDOSECALCULATIONMANUAL(00CH)isasupportingdocumentofthe CPSES Technical Specification. Part I of the ODCM contains (1) t,he Radioactive Effluent Controls and Radiological Environmental Monitoring Programs required by Technical Specification 6.8.1. (2) descriptions of the information that should be included in the Annual Radiological Environmental Operating and Semiannual Radioactive Effluent Release Reports required by Technical Specifications 6.9.1.3 6nd 6.9.1.4, ant. (3) Controls for Meteorological Monitoring Instrumentation and 50aled Source Leakage. Part 11 of the ODCH describes the methodology and par *. meters to be used in the cak.ulation of offsite doses due to radioactive liquid and gaseous effluents and in the calculation of liquid and gaseous effluent monitoring instrumentation alarm / trip setpoints. Part 11 of the ODCM also contains a list and graphical description of the specific sample locations for the radiologict.1 environmental monitoring program. Liquid and Gaseous Radwaste Treatment System configurations are shown in Figures 1.1 and 2.1 The 00CM will be maintained at the plant for use as a reference guide and training docurnent on accepted methodologies and calculations. Changes in the calculation methods or parameters will be incorporated %to the ODCM in order to assure that the ODCM represents the present meth.^ ' y in all applicable areas. TO Electric initiated changes to the ODCH wil, ,e implemented in ,,

accorda::ce with Section 6.14 of the Technical Spec 1(ications.

The OOCH follows the methodology and models suggested by NUREG-0133 (Ref. 1) and Regulatcry Guide 1.109, Revision 1 (Ref. 2). Simplifying assumptions have bee applied in this manual where applicable to provide a more workable

/G V documeni for implementing the Radiological Effluent Control requirements.

This simplified approach will result in a more conservative dose evaluation, but requires the least amouit of time for establishing compliance with regulatory requirements.

This manual is designed to provide necessary information in order to simplify the dose calculations. Tte dose calculations can be optionally expanded to

1. severti levels of effort. The complexity of the dose calculations can be expanded by several levels of effort, aiming toward a full calculaticn in accordance with Regulatory Guide 1.109. Future changes to the ODCM may be initiated to implement more complex calculations as systems become available and are validated that can reliably, economically and properly perform these more complex calculations. A beneficial approach to implementing the Radiological Effluent Control '.ogram and Regulatory Guide 1.21 (Semiannual Radioactive Efflue9 Release Report) requirements is to use a computerized system to determine the effluent releases and update cumulative doses.

& Where additional claiification or information is required to adequately implement certain ODCM requirements, supplemental guidance is provided in Appendix G of Part !!.

This control applies to the release of radioactive materials in liquid effluents from each unit at the site. For units with shared Radwaste Systems, the liquid units effluents sharing from the shared system are to be proportional among the that system.

3/4.11.1.3 L10VID RADWASTE TREATMENT SYSTEM The OPERABILITY of the Liquid Radwaste Treatment 3ystem ensures that this system will be available for use whenever liquia effluents require treatment prior to release to the environment. The requirement that the appropriate portions of this system be used when specified provides assurance that the releases of radioactive materials in liquid effluents will be kept "as low as is reasonably achievabla." This control implements the requirements of 10 CFR 50.36a, General Design Criterion 60 of Appendix A to 10 CFR Part 50 and the design objective given in Section !!.0 of Appendix 1 to 10 CFR Part 50. The specified limits governing the use of appropriate portions of the liquid Radwaste Treatment System were specified as a suitable fraction of the dose design objectives set forv.h in Section II.A of Appendix I, 10 CFR Part 50 for liquid effluents.

This control applies to the reicase of radioactive materials in liquid effluents from each unit at the site. For units with shared Radwaste Systems, f

( the liquid effluents from the shared system are to be proportioned among the units sharing that system.

3/4.11.1.4 LVW POND RESIN INVENTORY The inventory limits of the LVW Pond are based on limiting the 7 consequences of an uncontrolled release of the pond inventory. The expression in Control 3.11,1.4 assumes the pond inventory is uniformly mixed, and that the pond is located in an unrestricted area as defined in 10 CFR Part 20, and that the concentration limit in Note 1 to Appendix B of 10 CFR Part 20 applies. This expression limits the total quantity of radioactive materials

.in resins discharged to the LVW Pond to a value such that the average concentration in the resins, calculated over the total volume of resins in the .

pond, will not exceed the Maximum Permissible Concentrations (MPCs) specified-in-10 CFR 20 Appendix B. Tdble 11, Column 2.

Because Control 3.11.1.1 limits the concentration of liquid effluents from other pathways to the LVW Pond to the 10 CFR 20 HPC values, also limiting the average concentration in resins to the MPC values will assure that the average concentration in the pond from all sources, calculated over the total volume of the pond (liquid and resins),

will not exceed the 10 CFR 20 HPC values.

normally discharges to SCR via the circulating Water Discharge Tunnel.

Alternatively, secondary waste streams may be routed to the Waste '

WaterHoldupTanks(WWHT). The WWHis may be released on a batch basis to the LVW Fond or to SCR via the Circulating Water Discharge Tunnel, depending on the levels of radioactivity present. Table 4.11-1 of Part I of this document' requires that secondary waste streams be diverted to the WWHT's if radioactivity is present in the waste stream in concentratiens that exceed the limits of 10 CFR 20 Appendix B.

1.1 10 CFR 20 AND RADIOLOGICAL EFFLUENT CONTROL COMPLIANCE To demonstrate compliance with 10 CFR 20.106, 00CM 7 Radiological Effluent Control 3/4.11.1.1 requires that the concentration of radioactive material released in liquid effluents to UWRESTRICTED AREAS be limited to the concentrations specified in 10 CFR 20, Appendix B. Table 11, Column 2, for radionuclides other than dissolved or ettrained noble gases, and to 2E-4 uti/mi for dissolved or e,1 trained noble gases. 10 CFR 20 compliance is checked for all

() discharges to SCR via the Circulating Water Discharge Tunnel ,

listed in Table 1.1. Because the LVW Pond is located in an UNRESTRICTED AREA, discharges to the LVW Pond are also checked for 10 CFR 20 compliance. If radioactive materials are present in the LVW Pond discharge in concentrations that, exceed 10% of the limits of 10 CFR 20. Appendix B. Table 11, Column 2, then all inputs to the LVW Pond are sampled and checked for compliance with 10 CFR 20. The following methodology is used to determine compliance with these limits.

a. Discharges to SCR via Circulating Wtter Discharge Tunnel  !

t Since liquid effluents from the radwaste treatment 7 system, Waste Water Holdup Tanks and the LVW Pond are j

mixed with circulating water prior to being discharged

(

to Squaw Creek Reservoir, compliance with 10 CFR 20 is a function of the circulating water flow rate. The maximum circulating water flow rate per plent is 1.1  !

million gpm. This is determined from the Ingersoll-

-Rand pump curves (Fig. 1.2) which indicate a flow rate 7 per pump of 275,000 gpm. The actual circulating water dilution flow is given by:  !

F(diluting flow) = ( %)0 gpm/ pump) x (# of pumps) x 0.9 7 (Eq. 1-2]

Where: 0.9 = Safety Factor to compensate for flow 7

fluctuations from the rate predicted by the circulatingwaterpumpcurves(Fig.1.2).

As an additional consideration --the available_ dilution flow 7 for any release may be corrected'to allow for simultaneous releases from_the Radwaste Processing System, a Waste Water Holdup Tank,'and/or the LVW Pond (i.e., a radwaste system tank, a Waste Water Holdup Tank, and the LVW Pond may be dischargedsimultaneously.)

1.2.1 Primary Liouid Effluent Monitor XRE-5253 7 i

To ensure that releases from the primary radwaste processing 7 system do not exceed 10 CFR 20, Appendix B. Table !!, Column 2 limits at .5e point of release to the UNRESTRICTED AREA, a radiation detector (XRE-5253) monitors discharges to the Circtdating Water Discharage Tunnel. XRV-5253 is the isolation valve controlled by XRE-5253. The isolation valve shuts automatiacally if the detector alarms on high radiation or a detector operation failure occurs. The methodology for determining the setpoint for detector XRE-5253 is given below.

It should be noted that the liquid effluent monitor setpoint values determined using the methodology from this section will be regarded as upper bounds for the actual setpoint adjustments. That is, setpoints may be established 4

at values lower than the calculated values, if desired.

Further, if the calculated value should exceed the maximum range of the monitor, the setpoint shall be adjusted to a value that falls within the normal operating range.of the monitor.

Cg , = (ADF/RDF) x C (Eq. 1-7} 7 Where: Cjw = The liquid waste effluent monitor alarm setpoint. This corresponds to the gamma concentration in the undiluted waste stream which after dilution would result in MPC-level releases (uCi/ml).

All other variables are as previously defined.

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 Radiological Effluent Control 3/4.11.1.1, Table 4.11-1. Table Notation 2. Figure 1.3 is a representative energy spectrum 7 response for the RD-33 type detector used in XRE-5253. This curve illustrates that for any given mixture of the most probable gamma emitting nuclides present, the conversion factor between counts per minute and microcuries por  ;

milliliter remains relatively constant. In fact between  :

137C s and 60 C0, tne total change in sensitivity is approximately 7%. Because this is well within the accuracy of measurement, there is no need to change the software sensitivity for given varied effluent concentrations.

However, should the concentration of previously unexpected nuclides become significant, further evaluation would be required.

1.2.2 TURBINE BUILDING SUMP EFFLUENT RADIATION MONITOR 1RE-5100 The purpose of the turbine building sump monitor (1RE-5100) is to monitor turbine building sump discharges and divert this discharge from the Low Volume Waste Pond to the Waste Water Holdup Tanks if radioactivity is detected. Because the only sources of water to the turbine building sump are from the secondary steam system, activity is expected only if a significant primary-to-secondary leak is present. Since detectable radioactivity is not normally present in the Turbine Building Sump, the monitor setpoint should be established as close to background as practical to prevent spurious alarms and yet alarm should not inadvertent radioactive release occur. To this end, the setpoint will be initially estab1hhed at three (3) 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 discharges from the LVW Pond to the Waste Water Holdup Tanks where the effluent can thEn be COMANCHE PEAK - UNii 1 11 1-9 Rev. 7 12/91

sampled and released in a batch mode to Squaw Creek Reservoir, if required by Radiological Effluent Control 3/4.11.1.1. Table 7 4.11-1. When radioactive materials are detected in the Turbine Building Sump, a setpoint then may be established for 1RE-5100 using the methodology in Section 1.2.1 to ensure that 10 CFR 20 MPC limits are not exceeded in discharges to the LVW Pond.

1.2.3 $ERVICE WATER EFFLUENT RADIATION MONITORS 1RE-4269/4270 The concentration of radioactive material in the service water effluent line normally is expected to be insignificant.

Therefore, the monitor alert alarm setpoint should be established as close to background as practival to prevent spurious alarms and yet alarm should an inadvertent release occur. To this end, the alarm setpoint will be initially Mtablished at three (3) times background until further data can be collected. If this effluent stream should become contaminated, radionuclide concentrations should be determined from grab samples and a radiation monitor alarm setpoint determined as follows:

C =(IC ) + DF  % . 1-8) s Where: Csq = the Servich Water effluent monitor alarm setpoint.

Cg = the concentration of each measured gamma emitter g, observed in the effluent (uCi/ml)

DF = [ (Ct /MPCj) = the dilution factor required to ensure maximum permissible concentrations are not exceeded.

For this release pathway no additional dilutio: is available.

Therefore, if the calculated DF is greater athan 1.0, any  :

releases occurring via this pathway will result in a violation  ;

of Radiological Effluent Control 3/4.11.1.1. If radioactivity  !

is detected in this release stream, doses due to releases from this %tream shall be calculated in accordance with the

,q methodology given in Section 1.3. with the near field average V dilution factor, F k, equal to 1.0.

1.3 DOSE CALCULATION FOR L10010 EFFLUENTS For implementation of Radiological Effluent Control 3/4.11.1.2, the dose comitment from the release of liquid effluents will be calculated at least once per 31 days and a cumulative sumation of the total body and organ dose comitments will be maintained for each calendar cuarter and each calendar year. Dose calculations will be performed for 7 reletses from the Waste Monitor Tanks, laundry Holdup &

Although the LVW Pond is located in an UNRESTRICTED AREA, dose calculations for discharges to the LVW Pond will not be performed because there are no real pathways for exposure to members of the public. Doses for these pathways will be caluciated when the LVW Pond is dischartid to Squaw Creek Reservoir.

NOTE: This calculation is only required if activity is detected in water and/or fish in excess of the appropriate LLD values given in Radiological Effluent Control 3/4.12.1. Table 4.12-1. If the measured activity in water or fish is less than the required LLO values, the concentration for that particular pathway is assumed to be zero.

7 1.4 DOSE PROJECTIONS FOR LIOUID EFFLUENTS Radiological Effluent Control 3/4.11.1.3 requires that appropriate subsystems of the liquid radwaste treatment system by used to reduce releases of radioactivity when the projected doses due to the liquid effluent from each reactor unit to UNRESTRICTED AREAS would exceed 0.06 mrem total body or 0.2

-mrem to any organ in a 31-day period. The following calculational nethod is provided for performing this dose projection.

At least once every 31 days, the total dose from all liquid releases for the quarter-to-date will be divided by the number of days into the quarter and multiplied by 31. Also, this dose projection shall include the estimated does due to any anticipated unusual releases during the period for which the projection is made. If this projected dose exceeds 0.06 mrem total body or 0.2 -rem any organ, appropriate portions of the Liquia Radwaste Treatment System shall be used to reduce v radioactivity levels Rrior to release.

Preface The-Effective Page Listing (EPL) provides a tabulation of the current pages in the CPSES ODCH.

Each page in_the CPSES ODCM is identified with a page number, including pages that contain tables or figures.

A-revision number and date are included on each page. The revision number and date are' changed when the change represents a substantive revision to the information-that.is provided-on the page. If the page-is revised or= reprinted but the-revision'is not considered substantive (i.e., it is an editorial correction), the revision numoer will not be changed._but will have the reprint date.

- Sirce the EPL may not be updated with-each revision, an Instruction Sheet (s) 1will.be provided for subsequent revisions of the CPSE5 ODCH: it should be retainediimrtdiately in front of the EPL. To identify the effective revision level of a page in the CPSES CDCM, check these Instruction Sheets first and, if not found, the EPL secoau.

If'any effective page cannot be'found, notify TV Electric Nuclear Licensing -!

and the required effective pages will be provided. Contact may-be made by

(-'s t

phone (214/812 4358) or by mail. A marked up copy of pages from the~

Instruction Sheets or the EPL is a convenient way to identify the required pages.
