INTRODUCTION The OFFSITE DOSE CALCULAT %. MANUAL is a supporting document of the RADIOLOGICAL EFFLUENT TECHNICAL SFECIFICATIONS. As such the ODCM describes the methodology and pa . ers 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 instrumen,tation alarm / trip setpoints. The ODCM contains a list and graphical descript' ion of the specific sample locations for the radiological environmental monitoring program. Minimum OPERABLE configurations of the liquid and gaseous radwaste treatment systems are also included. The ODCM will be maintained at the Station for use as a reference guide and training document of accepted methodologies and calculations. Changes in the calculational methods or parameters will be incorporated into the ODCM in order to assure that the 00CM represents the present methodology in all applicable areas. Computer software to perform the described calculations will be maintained current with this ODCM. I l l I I l l l ODCM, V C Summer, SOUTH CAROLINA ELECTRIC AND GAS CO. v I

1.0 LIQUID EFFLUENTS The Virgil C. Summer Nuclear Station is located on the Monticello Reservoir which provides supply and discharge for the plant circulating water. This reservoir also provides supply and discharge capacity for the Fairfield Pumped Storage Facility. The Parr Reservoir located below the pumped storage facility is located above the Parr Dam. There are two basic release nithways and sources of dilution for liquid effluents: the circulating water discharge canal and the liquid effluent line to the penstocks of the pumped storage facility. All liquid effluent pathways discharge to either one or the other release point. Generally speaking, very low concentrations of radioactive waste are discharged to the circulating water discharge while generally higher concentrations of radioactive waste are released to the penstocks of the p imped storage f acility during the generation cycle. 1.1 Liouid Effluent lionitor Setpoints The calculated setpoint values will be regarded as upper bounds for ' e actual setpoint adjustments. That is, setpoint adjustments are not required to be performed if the existing setpoint level corresponds to a lower count l rate than the calculated value. Setpoints may be established at values lower i than the calculated valuC3 if desired. 1.1.1 Liouid Radwaste Effluent Line Monitors l (RM-L5, RM-L7, RM-L9) l Liquid Radwaste Effluent Line Monitors provide alarm and automatic termination of release functions prior to exceeding the concentration limits specified in 10CFR 20, Appendix B, Table II, Column 2 at the release point to the unrestricted area. To meet I l l 00CM, V C Summer, SOUTH CAROLINA ELECTRIC AND GAS CO. 1.0-1

1.1.1 Liouid Cadwaste Effluent Line Monitors (Continued) s this specification, the alarm / trip setpoints for liquid effluent monitors and flow measurement devices are set to assure that the following equation is satisfied: h <_ C x RF (1) where: C the effluent concentration limit (Specification 3.11.1.1) implementing 10CFR 20 for the site, corresponding to the specific mix of isotopes in the effluent stream being considered for discharge, in uCi/ml. RF = the recirculation factor, determined by' system equilibrium calculations, used to assure that concentrations of effluents at the outfall do not exceed the effluent concentration limit, C. RF - 0.5. (Reference 6) the setpoint, in pCi/ml, of the radioactivity monitor measuring c - the radioactivity concentration in the effluent line prior to dilutien and subsequent release; the setpoint, which is inversely proportional to the volumetric flow of the effluent line and proportional to the volumetric flow of the dilution l stream plus the effluent stream, represents a value which, if exceeded, would result in concentrations exceeding the limits of l 10CFR 20 in the unrestricted area. l l f the flow setpoint as determined at the radiation monitor = location, in volume per unit time, but in the same units as F, below. the dilution water flow retpoint as determined prior to the F = releMe point, in volume per unit time. ODCM, V C Summer, SOUTH CAROLINA ELECTRIC AND GAS CO. 1.0-2

At the Virgil C. Summer Nuclear Station the Liquid Waste Processing System and the Nuclear Blowdown System both discharge to the penstocks of the Fairfield Pumped Storage Facility through a common line. The available dilution water flow (Fdp) is assumed to be 90 percent of the flow through the Fairfield Pumped Storage Station penstock (s) to which liquid effluent is being.11scharged and is dependent upon operational status of the Fairfield Pumped Storage Station. The viaste tank flow rat,es (fdn' Idb and foc) and the monitor setpoints (c, c and c ) are set to meet the condition g B C of eouation (1) for a given effluent concentration, C. The three monitor I set;aints are indicative of the monitor system configuration for this discharge pathway. The LWDS discharges through RM-LS, which has setpoint cg for alarm / control functions over releases from either Waste Monitor Tanks 1 or 2. The Nuclear Blowdown discharges through RM-L7, which also has setpoint. cB for alann/ control functions over releases from the Nuclear Blowdown Tank. These two relear.e pathways merge into a common line monitored by RM-L9, which has setpoint c for control functions over the cor:non effluent line'. C The method by which this is accomplished is as follows: I 1) The isotopic concentration for a waste tank to be released is obtained from the sum of the measured concentrations as determined by the analysis required in the Radiological Effluent Technical Specifications Table 4.11-1: l EC$=IC +C +C +C (2) g a s t i g l where: C 4 the concentration of nuclide i as determined by the = analysis of the waste sample. ODCM, V C Summer, SOUTH CAROLINA ELECTRIC AND GAS CO. 1.0-3

C the sum of the concentrations C of eacn measured gamma g g emitting nuclide observed by gamma-ray spectroscopy of the waste sample. C* the measured concentrations C of olpha emitting nuclides = a a observed by gross alpha analysis of the monthly composite sample. I C* th? measured concentrations of Sr-39 and Sr-90 in liquid s waste as determined by analysis of the quarterly composite sample. I C* the measured concentration of H-3 in liquid waste as t determined by analysis of the monthly composite. The C term will be included in the analysis cf each batch; g terms for alpha, strontium, and tritium may be included as appropriate.. Isotopic concentrations for both the Waste Monitor Tanks and the Nuclear Blowdown Monitor Tank may be calculated using equation (2). 2) Once isotopic concentrations for either Waste Monitor Tank and/or the Nuclear Blowdown Monitor Tank have been determined, these values are used to calculate a Dilution Factor, DF, which is the ratio of dilution flow rate to tank flow rate (s) required to assure that the limiting concentration of 10CFR, Part 20, Appendix B, Table II, Column 2 are met at the point of discharge. Values for these concentrations will be based on previous coa.cosite sample analyses as required by Table 4.11-1 of the Radiological Effluent Technical Specifications.

First the appropriate Dilution Factor is calculated by E E applying equation (3). If only one tank is being considered for discharge, calculate DF using the appropriate concentration ratio term I 1 (i.e. M or B) with the other concentration ratio term set equal to zero. If both tanks are to be discharged simultaneously, calculate DF with both concentration ratio terms included in equation (3). i 00CM, V C Sumner, SOUTH CAROLIriA ELECTRIC Afl0 GAS CO. 1.0-5 I

The monitor response is primarily to gamma radiation, therefore, the actual setpoint is based on C. The monitor setpoint in cpm which corresponds to the g g particular setpoint concentration, c, is taken from the monitor calibration graph.

l 1.1.2 Detergent Waste Discharge Via Sanitary Waste System (RM-L5) In the Virgil C. Sum.er Nuclear Station liquid wasta effluent system design, there exists a mechanism for discharging detergent l wastes via the sanitary waste system. The sample point prior t.o l discha is normally Waste Monitor Tank No. 2. The analysis requirements are the requirements listed in the Radiological Effluent Technical Specifications, Table 4.11-1. This effluent pathway shall on'ly be used when the following condition is met: I 1 i (14) D - LLD where: -EC ~ the isotopic concentration of the detergent waste contained = 9 -D within the Waste Monitor Tank serving as the holding facility for sampling and analysis prior to discharge. the Lower Limit of Detection, (LLD), for the isotopic l E C. = I l i l - LLD concentrations of the Waste Monitor Tank as determined by the analysis required in the Radiological Effluent Technical Specifications, Table 4.11-1. When the conditions of equation (14) are met, the detergent \\ waste may be released via the Senitary Waste System pathway. There is no requirement to perform the Steps 2, 3, 4, or 5 of Section 1.1.1 if the conditions of equation (14) are met. 00CM, V C Summer, SOUTH CAROLINA ELECTRIC AND GAS CO. 1.0-10

f l l.1.3 Steam Generator Blowdown and Turbine Building Sump Effluent Lines (RM-L3,RM-L10,RM-L8) Concentrations of radionuclides in the liquid effluent discharges made via the Turbine Building Sump and Steam Generator Blowdown are expected to be very low or nondetectable. These releases are expected to be continuous in nature ano thus will be sampled in an appropriate manner as specified in Table 4.11-1 of the RETS. TheSteamGeneratorBlow$ownMonitorsandtheTurbine Building Sump Monitor provide alarm and automatic termination of release prior to exceeding'the concentration limits specified in 10CFR 20, Appendix B, Table II, Columri 2 at the release point to the unrestricted area. Both of these effluent pathways utilize the circulating water as dilution to the effluent stream with the circulating water discharge canal being the point of release into an unrestricted area. Equation (1) is again used to assure that effluents are in compliance with the aforementioned specification:

5. C x RF f

where c, f, F, C, and RF are the same generic terms discusseo in Section 1.1.1. l The common usage of the Circulating Water System for dilution of both the Steam Generator Blowdown and the Turbine Building Sump effluents is similar to the release mechanism utilized by the higher activity effluents in Section 1.1.1. The basic difference is that the two pathways do not merge into a single discharge line. Therefore, only individual pathways are monitored. I ODCM, V C Summer, SOUTH CAROLINA ELECTRIC AND GAS CO. 1.0-11

The available dilution water flow (Fdc) is dependent upon the mode of operation of the Circulating Water System. Any change in this value will be accounted for in a recalculation of equation (1). The Stean. Generator Blowdown flow rate (fds), the Turbine Building Sump flow rate (fdt), and the monitor setpoints (cSa' cSb, and c ) are also set to meet the condition of ecuation T (1). The three monitor setpoints corr,espond to the methodology of the two release pathways. RM-L8, the' Turbine Building Sump monitor alarms and terminates release upon exceeding the monitcr setpoint (c ). RM-L3, the first monitor in the Steam Generator Blowdown T discharge pathway, alarms and terminates release of the stream. The discharge is then manually diverted to the Nuclear Blowdown Processing System. RM-L10, the last monitor in the Steam Generator Blowdown discharge pathway, alarms and terminates the release. Thus, RM-L10 is basically redundant to RM-L3 and the setpoint (cSb) will be determined in the'same manner as RM-L3 (cSa). The r1: hod by which the monitor setpoints are determined is as fullows: I 1) The isotopic concentrations for either release source to be or being released are obtained from the sum of the measured concentrations as determined in the Radiological Effluent Technical Specifications Table 4.11-1. Ecuation (2) is again employed for this calculation: ICg=EC +C +C +C g a s t 1 9 I ODCM, V C Summer, SOUTH CAROLINA ELECTRIC AND GAS CO. 1.0-12

Isotopic concentrations for both the Steam Generator Blowdown System effluent and the Turbine Bu11dir.g Sump effluent may be calculated using equation (2). i 2) Once isotopic concentratiens for either the Steam Generator Blowdown or the Turbine Building Sump have been determined, these values are used 1 to calculate a Dilution Factor, DF, which is the ratio of the total dilution flow rete to effluent stream flow rate (s) required to assure l that the limiting concentration of 10CFR, Part 20, Appendix 8, Table II, Column 2 are met at the coint of discharge.

Due to the 0.25 safety factor in equations (1) and (2), the release rate also must be controlled such that the ratio of dose rate limit (D'TB U" D'ss) to the dose rate which would result from the planned release (X/Q f K q$ ) or,[ X/Q f (L; + 1.1 M ) g ] j j j is greater than four (4). Also, a setpoint calculation should be performed for the plant vent monitor (RM-A3) incorporating the waste gas decay system planned relase rates with the existing plant vent release rates to determine whether the plant vent monitor setpoint should be adjusted. When no discharges are being made from the Waste Gas Decay System, the monitor setpoint should be E.stablished as near background as practical to prevent spurious alarms yet l alarm in the event of an inadvertent release.
