CHAPTER 10 RADIOACTIVE EFFLUENT TREATMENT AND MONITORING 10.1 AIRBORNE RELEASES 10.1.1 System Description A simplified gaseous radwaste and gaseous effluent flow diagram is provided in Figure 10-1.
Each airbome release point is classified as stack, vent, or ground level in accordance with the definitions in Section 4.1.4 and the results in Table A-1 of Appendix A. The principal l release points for potentially radioactive airbome effluents and their classifications are as follows:
The ventilation chimney (a stack release point).
The reactor building ventilation stack (a vent release point).
10.1.1.1 Condenser Offgas Treatment System The condenser offgas treatment system is designed and installed to reduce radioactive' gaseous effluents by collecting non-condensable off-gases from the condenser and providing for holdup to reduce the total radioactivity by radiodecay prior to release to the environment. The daughter products are retained by charcoal and HEPA filters. The system is described in Section 11.3.2.1.1 of the Quad Cities UFSAR. ,
Ventilation Exhaust Treatment System 10.1.1.2 Ventilation exhaust treatment systems are designed and installed to reduce gaseous radioiodine or radioactive material in particulate form in selected effluent streams by passing ventilation or vent exhaust gases through charcoal adsorbers and/or HEPA filters prior to release to the environment. Such a system is not conside ed to have any ef'ect on noble gas effluents. The ventilation exhaust treatment systems are shown in Figure 10-1.
Engineered safety features atmospheric cleanup systems are not considered to be ventilation exhaust treatment system components.
10.1.2 Radiation Monitore 10.1.2.1 Piet t Chimney Monitor Monitors 1(2)-1730A/B continuously monitor the final effluent from the chimney.
The monitor system has isokinetic sampling, gaseous grab sampling, iodine and particulate sampling, and tntium sampling capability.
10-1
QUAD CITIES Rsvision 1.8 Juna 1996 g The chimney effluent is also monitored by a separate particulate, iodine, and noble gas (SPING-4) system and a Victoreen system. The SPINGNictoreen system has high range capabilities to deal with accident conditions including postaccident sampling capability.
The Victoreen sampling system automatically begins taking samples after a high signal has been received on the SPING-4 low range noble gas monitor. Output from the SPINGNictoreen system is obtainable in the control room.
No automatic isolation or control functions are performed by these monitors. Pertinent information on these monitors is provided in the Quad Cities UFSAR Section 11.5.2.3.
10.1.2.2 Reactor Building Vent Stack Effluent Monitor The combined reactor buil6ng ventilation is also monitored by a SPING-4. This monitor has high range capabilities to deal with accident conditions. The SPING-4 noble gas detectors have ranges that envelope the range for the reactor building vent effluent trip -
point.
The vent stack monitor has isokinetic sampling and iodine and particulate sampling capability.
I No automatic isolation or control functions are performed by this monitor. ,
j Pertinent information on this monitor is provided in the Quad Cities UFSAR Section 11.5.2.4.
10.1.2.3 Reactor Building Ventilation Monitors Monitors 1(2)-1735A/B continuously monitor the effluent from the Unit 1(2) reactor building. On high high alarm, the monitors automatically initiate closure of valves A01(2)A-5741, A01(2)B-5741, A01(2)A-5742, and A01(2)B-5742 thus isolating the Unit ,
1(2) reactor building, and initiate startup of the Unit 1(2) standby gas treatment system.
and isolates control room HVAC.
In addition to the above monitors, there is continuous iodine and particulate sampling of the reactor building exhaust.
Pertinent information on these monitors is provided in Quad Cities UFSAR Section 11.5.2.4.
10.1.2.4 Condenser Air Ejector Monitors Monitors 1(2)-1733A/B continuously monitor gross gamma activity downstream of the steam jet air ejector and prior to release to the main chimney.
On high high alarm the monitors automatically activate an interval timer which in turn initiates closure of air operated valve A01(2)-5406, thus terminating the release.
In addition, monitors 1(2)-1741 continuously monitor the final offgas effluent prior to entering the chimney, and monitors 1(2)-1738 continuously monitor gross gamma activity downstream of the steam jet air ejector. No control device is initiated by these monitors.

10.1.3 Alarm and Trip Setpoints 10.1.3.1 Setpoint Calculations 10.1.3.1.1 Reactor Building Vent Stack Monitors The setpoint for the reactor building vent stack monitor is conservatively set at 2 mr/hr above background. The reactor building ventilation stack release rate, Q , at 2 mr/hr is calculated to be 14,400 pCi/sec. Q. is then substituted into Equations 10-1 and 10-2 to l
determine Q..
l 10.1.3.1.2 ,
Condenser Air Ejector Monitors The high-high trip setpoint is established at $100 Ci/sec per MWt (=2.5E5 Ci/sec) and the high alarm is established at $50 Ci/sec per Mwt (=1.25E5 Ci/sec).
10.1.3.1.3 Plant Chimney Radiation Monitor The setpoints for the plant chimney radiation monitor are conservatively set at 10,000 pCl/sec and 20,000 Ci/sec (high and high-high alarms respechvely).
At this level the combined release from chimney and vent is approximately 10% of the RETS limit. This is determined by solving Equations 10-1 and 10-2 below. ,
10.1.3.2 Release Limits Alarm and trip setpoints of gaseous effluent monitors are established to ensure that the release rate limits of RETS are not exceeded. The release limit Q is found by solving Equations 10-1 and 10-2.

QUAD CITIES Revision 1.8 Junn 1996 Q. Total Allowed Release Rate, Stack Release ( Ci/sec]
The total Allowed release rate of all noble gas radionuclides released as stack releases.
Ou Total Allowed Release Rate, Vent Release (pCi/sec)
The total allowed release rate of all noble gas radionuclides released as vent releases.
The remaining parameters in Equation 10-1 have the same definitions as in Equation A-8 of Appendix A. The remaining parameters in Equation 10-2 have the same definition as in
- Equation A-9 of Appendix A.
Equation 10-1 is based on Equation A-8 of Appendix A and the RETS restriction on whole body dose rate (500 mremlyr) due to noble gases released in gaseous affluents (see Section A.1.3.1 of Appendix A). Equation 10-2 is based on Equation A-9 of Appendix A and the RETS restriction on skin dose rate (3000 mremlyr) due to noble gases released in gaseous effluents (see Section A.1.3.2 of Appendix A).
The value of Equation 10-1 (2.3 x 10' Ci/sec) is used as the limiting noble gas release rate. ,
Calibration methods and surveillance frequency for the monitors will be conducted as specified in the RETS.
10.1.3.3 Release Mixture in the determination of alarm and trip set points the radioactivity mixture in the exhaust air l Is assumed to be the same as the analysis of a representative sample of noble gases collected at the recombiner during the calendar quarter in which the monitor is recalibrated.
10.1.3.4 Conversion Factors The conversion factors used to establish gaseous effluent monitor setpoints are obtams as follows.
Reactor building vent efflut 4 :nonitor.
The monitor setpoint is established at 2 mr/hr above background. For the purpose of setpont determination it is assumed that the background is 1 rnt ~<
There is sufficient conservatism in the setpoint calculation to accommodate ,
routine variations in the background. However, the isotopic analysis in Sect:cn l 10.1.3.3 is used to confirm that the setpoint is conservative.

QUAD CITIES R& vision 1.8 Juns 1996 Plant chimney monitor.
Calibration of the plant chimney monitor consists of recirculating an amount of off-gas (see 10.1.3.3) through the noble gas monitors and a Marinelli beaker.
After readings have stabilized, the Marinelli beaker is removed and gamma isotopic analysis performed. The efficiency is determined from a plot of average gamma energy of the off-gas sample and net monitor readings.
10.1.3.5 HVAC Flow Rates The HVAC exhaust flow rates may be obtained from the process computers, indication in the control room, or fan combinations. Setpoints were calculated using the following values:

- contributions from both units. Under normal operating conditions, it is difficult to l
allocate the radioactivity between units due to fuel performance, in-plant leakage, l power history, and other vanables. Consequendy, allocation is normally made evenly between the units. During extended unit sh'utdowns or penods of known differences.
l the apportionment is adjusted accordingly. The allocation of effluents is estimated on ..
a monthly basis.

The liquid radweste treatment system is designed and installed to reduce radioactive liquid effluents by collecting the liquids, providing for retention or holdup, and providing for treatment by domineralizer for the purpose of reducing the total radioactivity prior to release to the environment. The system is described in Section 11.2 of the Quad Cities UFSAR.
10.2.1.1 River Discharge Tank There is one river discharge tanF. (65,000 gallons capacity) which receives water for discharge to the Mississippi River. This is the only release path in use.
10.2.2 Radiation Monitors 10.2.2.1 Liquid Radwaste Effluent Monitor Monitor 1/2-1799-01 is used to monitor all releases from the river discharge tank. Dn high alarm the release is terminated manually.
Pertinent information on the monitor and associated control devices is provided in Quad Cities UFSAR Sections 11.5.2 and 11.5.3.
l 10.2.2.2 Service Water Effluent Monitors Monitors 1(2)-1799-01 continuously monitor the service water effluent. No control device is initiated by these monitors.
Pertinent information on these monitors is provided in Quad Cities UFSAR 11.5 3 10.2.3 Alarm and Trip Setpoints 10.2.3.1 Setpoint Calculations Alarm and trip setpoints of liquid effluent monitors at the principal release points are established to ensure that the limits of RETS are not exceeded in the unrestncted area.
I Currently these setpoints are based on the most conservative releases during the l previous 18 months. If it is determined that tie N no longer conservative, the setpoints are reevaluated.

QUAD CITIES Rsvision 1.8 Jun31996 10.2.3.4 Release Mixture For the liquid radwaste effluent monitor the release mixture used for the setpoint determination is the radionuclide mix identified in the grab sample isotopic analysis {t plus four additional radionuclides. The additional radionuclides are H-3, Fe-55, Sr-89, and Sr-90. The quantities to be added are determined using scaling factors denved from station release data for the previous six months.
10.2.3.5 Conversion Factors The readout for the liquid radwaste effluent monitor is in CPM. The calibration constant is based on the detector sensitivity to Cs-137.
10.2.3.6 Liquid Dilution Flow Rates The dilution flow is determined using Equation 10-6 below.
8 F = (N" x F" + N" x F" - F'C') (10-6)
F' = Dilution flow (gpm)
N" = Number of circulating water pumps on.
F" = 157000 gpm Flow with one circulating water pump on.
N" = Number of service water pumps on

F ca = Deicing flow 10.2.4 Allocation of Effluents from Common Release Points ,
't' Radioactive liquid effluent released from the release tank is comprised of contributions from both units.
Allocation of waste is achieved by comparing the pump timer totals for each unit's floor drain and equipment drain pumps to the amount of waste sent to the river discharge tank from the floor drain and waste collector storage tanks. Liquid effluerts from laundry and chemical waste are allocated evenly between units. During extended unit shutdown or periods of significant plant input differences, the apportionment is adjusted accordingly. The allocaton of the effluents is made on a monthly basis.
10.2.5 Projected Concentrations for Releases if total DWC is greater man 25, the projected dose due to liquid effluent releases is calculated. Otherwise, the releases from the previous month are used to estimate trie projected dose for the coming month using the methodology in Seebon A.2 of Appendix A. (See Section A.2.1 of Appendix A).

The value of "s," used in the calculatiori of the LLD for a detecbon system shall be based on an actual observed background count or a blank sample count (as appropriate) rather than on an unverified theoretically predicted value. Typical values of "E", "V", "Y", "t", and "At" shall be used in the calculation.
For gamma ray radionuclide analyses the background counts are determined from the total counts in the channels which are within plus or minus one FWHM (Full Width at Half Maximum) of the gammts ray photopeak energy normally used for the quantitative analysis for that radionuclide. Typical values of the FWHM shall be used in the calculation.
The LLD for all measurements is defined as an "a priori" (before the fact) limit representing the capability of a measurement system and not as an "a posteriori" (after the fact) limit for a particular sample measurement.

If desired, more realistic parameters cow be used in place of these to refine the estimate. For example, one could determine whether the nearest resident really fishes the specified number of hours at the specified location. The amount of time in a year that a maximally exposed fisherman would spend fishing near the s a is estimated as 12 hours per week for 8 months per year. This yields an estimate of: [12 hours / week] [(8 months /yr)/(12 months /yr)] x [52 weeks /yr] = 416 hours /yr The remaining time is assumed to be spent at the nearest residence. Distance to nearest residence (See Table F-3).
- Estimated from drawings of the site.
- The OF,is the quotient of the number of hours a location is occupied and the number of hours .n a ,
year. Thus OH,/8760 hours = OF, rounded to the 0.01 digit. l l Multiplication factor for hydrogen addition. Refer to equation A-34 of Appendix A. NE F-39
