5.1 Precautions
5.1.1 None 5.2 Limitations 5.2.1 In Section 8.1, Alarm Setpoints, of this procedure effluent monitor setpoints for a conservative mix are based on the individual units specific parameters, but effluent monitor setpoints for analysis prior to release permit use the total dilution flow available at the site. 5.2.2 BV-1 and BV-2 utilize the concept of a shared liquid radioactive waste system according to NUREG-0133.<
3.u.1) This permits the mixing of liquid radwaste for processing and allocating of dose due to release as defined in Section 8.4, Liquid Radwaste System. 5.2.3 A difference in alarm setpoint terminology for the radiation monitoring systems of BV-1 and BV-2 is described as follows: 5.2.3.1 5.2.3.2 HIGH and HIGH-HIGH terminology are used for BV-1 monitors and ALERT and HIGH terminology is used for BV-2 monitors.
BV-1 alarm setpoint units are expressed as counts per minute (cpm) and BV-2 alarm setpoints units are expressed as microcurie per milliliter (uCi/mL).
The difference is due to BV-2 software which applies a conversion factor to the raw data (cpm) to convert units to uCi/ml. Note that the uCi/ml presentation is technically correct only for the specific isotopic mix used in the determination of the conversion factors. Therefore, BV-2 setpoints determined on analysis prior to release will be correct for properly controlling dose rate, but the indicated uCi/ml value may differ from the actual value.

and [RM-lLW-116]
can be varied based on actual operating conditions resulting in changes in the discharge and dilution flow rates as follows: 542F HHSP=--f -[l.1(1)-1]
where: HHSP =Monitor HIGH-HIGH Alarm Setpoint above background (ncpm). 542 =Most restrictive proportionality constant based on nominal flow conditions:
542 = 3.53E+5 ncpm x 35 gpm + 22,800 gpm [RM-lLW-104]
542 = 8.24E+5 ncpm x 15 gpm + 22,800 gpm [RM-lLW-116]

The maximum acceptable radioactivity concentration (uCi/ml) ofradionuclide "i" in the liquid effluent prior to dilution (Ci) was determined by: [1.1 (1 )-4] 8.1.1.1.4 BV-1 Monitor Count Rate The calculated monitor count rate (ncpm) above background attributed to the radionuclides; (CR) was determined by: [1.1(1)-5]
where: Ei = Detection efficiency of the monitor for radionuclide "i" ( cpm/uCi/ml) from ATTACHMENT A Table 1.1-la. If not listed in Attachment A, then obtained from Calculation Package ERS-SFL-92-039.
C 3.1.1.4) 8.1.1.1.5 BV-1 Monitor HHSP 8.1.1.2 The monitor HHSP above background (ncpm) should be set at the CR value. Since only one tank can be released at a time, adjustment of this value is not necessary to compensate for release from more than one source.-BV-1 Setpoint Determination Based On Analysis Prior To Release . The following method applies to liquid releases when determining the setpoint for the maximum acceptable discharge flow rate prior to dilution and the associated HHSP Alarm Setpoint based on this flow rate for the [RM-lLW-104], LIQUID . WASTE EFFLUENT MONITOR and the [RM-lLW-116], LAUNDRY AND CONTAMINATED SHOWER DRAINS MONITOR during all operational conditions.
The monitor alarm setpoint is set slightly above (a factor of 1.25) the count rate that results from the concentration of gamma emitting radionuclides in order to avoid spurious alarms. To compensate for this increase in the monitor alarm setpoint, the allowable discharge flow rate is reduced by the same factor. When the discharge flow rate is limited by the radwaste discharge pump rate capacity or by administrative selection rather than the allowable flow rate determined from activity concentration, the alarm setpoint will be proportionally adjusted based upon the excess dilution factor provided.

BV-2 Setpoint Determination Based On Analysis Prior To Release The following method applies to liquid releases when determining the setpoint for the maximum acceptable discharge flow rate prior to dilution and the associated HIGH Alarm Setpoint based on this flow rate for the Liquid Waste Effluent Monitor (2SGC-RQ100) during all operational conditions.
The monitor alarm setpoint is set slightly above (a factor of 1.25) the concentration reading that results from the concentration of gamma emitting radionuclides in order to avoid spurious alarms. To compensate for this increase in the monitor alarm setpoint, the allowable discharge flow rate is reduced by the same factor. When the discharge flow rate is limited by the radwaste discharge pump rate capacity or by administrative selection rather than the allowable flow rate determined .from activity concentration, the alarm setpoint will be proportionally adjusted based upon the excess dilution factor provided.

To meet this requirement tank recirculation time is calculated using actual tank volumes and recirculation pump capacity.
BV-1 and BV-2 will show compliance with ODCM Control 3.11.1.1 in the following manner: The activity of the various radionuclides in the batch release, determined in accordance with 1/2-0DC-3.03, Table 4.11-1, is divided by the minimum dilution flow to obtain the concentration at the unrestricted area. This calculation is shown in the following equation:

Page Number: 28of43 ODCM: LIQUID EFFLUENTS 8.4.1.11 [lLW-RWR0-1], RAD WASTE REVERSE OSMOSIS (RWRO) SKID adds a physical membrane barrier to the chemical ion exchange system used in the current liquid waste demineralizer system. This replaceable membrane barrier prevents radwaste particles that were not captured during the ion exchange process. [lLW-RWR0-1]
does not capture the particles, but instead produces a reject stream separate from the permeate stream. The [lLW-RWR0-1]
accepts the effluent stream of the demineralizer system [lLW-I-3], LIQUID WASTE DEMINERALIZER and is designed to allow boron and silica particles to pass through while rejecting others such as antimony.
If antimony is present in the effluent stream it is separated and is sent to [lLW-I-3-5], Antimony Vessel charged with antimony selective resin. The antimony vessel removes the isotope from the reject stream prior to discharge back to the [1BR-TK-4A, ( 4B)], COOLANT RECOVERY TANK being processed from. This skid is located in the Solid Waste Building (elevation 735'-6").

Page Number: 31of43 ODCM: LIQUID EFFLUENTS 8.4.4 BV-112 Miscellaneous Sumps 8.4.4.l Unit 1 Chemical Waste Sump This sump has an approximate capacity of 16,755 gallons and the associated trenches add an additional volume of approximately 5, 140 gallons. The waste in this sump is not processed through any liquid waste demineralizer for cleanup. This sump cannot be completely isolated and does not have any radiation monitors.
The sump discharges to.Unit 1 Liquid Waste Line that discharges to the Unit 1 Cooling Tower Blowdown Line. The Chemical Waste Sump typically does not receive radiological liquid waste. When primary to secondary leakage is greater than 0.1 gpm (142 gpd) releases of radioactive material from this sump are considered to be continuous liquid effluent discharge as specified in ODCM Control 3.11.1.1.
When the Turbine Building Sump concentration exceeds 1 OEC, the Chemical Waste Sump accepts flow from the Turbine Building Sump(s). Prior to discharge the Chemical Waste Sump is sampled. Individual liquid effluent batch discharge permits are not required if no Licensed Radioactive Material (LRM) is present and the discharge of tritium is accounted for with a monthly secondary diffusion permit. If LRM is detected in the Chemical Waste Sump, then a special permit is required.
Upon completion of filling operation, the sump must be recirculated a minimum of two (2) volumes prior to sampling for batch discharge permit preparation.
During normal plant operation, this sump may be used for the treatment and disposal of radiological materials for various projects at the discretion of site management.
When Licensed Radioactive Material from a source other than a Turbine Building drain of secondary water is added to the sump, the sump may be discharged using batch release methods if concentration and*dose limits are maintained.

Page Number: 32of43 ODCM: LIQUID EFFLUENTS 15 8.4.4.2 Unit 2 Cable Vault Sump This sump has a capacity of 2,424 gallons, however the high level alarm will actuate at 1,500 gallons. This sump cannot be completely isolated and does not have any radiation monitors.
The waste in this sump is not normally processed through a liquid waste demineralizer for cleanup because the sump may contain contaminants that would deplete the resin bed. The sump normally receives radiological liquid waste. It is used for the collection and release of contaminated water. The open pit design provides the potential for radiological materials to enter the sump due to its location in the Radiological Controlled Area thus requiring Offsite Dose Calculation Manual (ODCM) controls prior to discharge.
Prior to discharge the Cable Vault Sump is sampled. Licensed Radioactive Material entering the sump may be discharged using batch release methods if concentration and dose limits are maintained.
Typically, tritium is accounted for in monthly pre-release batch liquid effluent discharge permit. This sump discharges into the Unit 2 Catch Basin System at 2CB-4. Upon completion of filling operation, the sump must be recirculated a minimum of two (2) volumes prior to sampling for discharge permit preparation. -END-Beaver Valley Power Station Procedure Number: 1/2-0DC-2.01 Title: Unit: Level OfUse: 1/2 General Skill Reference ODCM: LIQUID EFFLUENTS Revision:

5.1 Precautions
5.1.1 None 5.2 Limitations 5.2.1 In Section 8.1, Alarm Setpoints, of this procedure effluent monitor setpoints for a conservative mix are based on the individual units specific parameters, but effluent monitor setpoints for analysis prior to release permit use the total dilution flow available at the site. 5.2.2 BV-1 and BV-2 utilize the concept of a shared liquid radioactive waste system according to NUREG-0133.<
3.u.1) This permits the mixing of liquid radwaste for processing and allocating of dose due to release as defined in Section 8.4, Liquid Radwaste System. 5.2.3 A difference in alarm setpoint terminology for the radiation monitoring systems of BV-1 and BV-2 is described as follows: 5.2.3.1 5.2.3.2 HIGH and HIGH-HIGH terminology are used for BV-1 monitors and ALERT and HIGH terminology is used for BV-2 monitors.
BV-1 alarm setpoint units are expressed as counts per minute (cpm) and BV-2 alarm setpoints units are expressed as microcurie per milliliter (uCi/mL).
The difference is due to BV-2 software which applies a conversion factor to the raw data (cpm) to convert units to uCi/ml. Note that the uCi/ml presentation is technically correct only for the specific isotopic mix used in the determination of the conversion factors. Therefore, BV-2 setpoints determined on analysis prior to release will be correct for properly controlling dose rate, but the indicated uCi/ml value may differ from the actual value.

Since only one tank can be released at a time, adjustment of this value is not necessary to compensate for release from more than one source.-BV-1 Setpoint Determination Based On Analysis Prior To Release . The following method applies to liquid releases when determining the setpoint for the maximum acceptable discharge flow rate prior to dilution and the associated HHSP Alarm Setpoint based on this flow rate for the [RM-lLW-104], LIQUID . WASTE EFFLUENT MONITOR and the [RM-lLW-116], LAUNDRY AND CONTAMINATED SHOWER DRAINS MONITOR during all operational conditions.
The monitor alarm setpoint is set slightly above (a factor of 1.25) the count rate that results from the concentration of gamma emitting radionuclides in order to avoid spurious alarms. To compensate for this increase in the monitor alarm setpoint, the allowable discharge flow rate is reduced by the same factor. When the discharge flow rate is limited by the radwaste discharge pump rate capacity or by administrative selection rather than the allowable flow rate determined from activity concentration, the alarm setpoint will be proportionally adjusted based upon the excess dilution factor provided.

In order to assure representative samples, at least two (2) tank volumes of entrained fluid from each tank to be discharged shall be recirculated.
To meet this requirement tank recirculation time is calculated using actual tank volumes and recirculation pump capacity.
BV-1 and BV-2 will show compliance with ODCM Control 3.11.1.1 in the following manner: The activity of the various radionuclides in the batch release, determined in accordance with 1/2-0DC-3.03, Table 4.11-1, is divided by the minimum dilution flow to obtain the concentration at the unrestricted area. This calculation is shown in the following equation:

Page Number: 32of43 ODCM: LIQUID EFFLUENTS 15 8.4.4.2 Unit 2 Cable Vault Sump This sump has a capacity of 2,424 gallons, however the high level alarm will actuate at 1,500 gallons. This sump cannot be completely isolated and does not have any radiation monitors.
The waste in this sump is not normally processed through a liquid waste demineralizer for cleanup because the sump may contain contaminants that would deplete the resin bed. The sump normally receives radiological liquid waste. It is used for the collection and release of contaminated water. The open pit design provides the potential for radiological materials to enter the sump due to its location in the Radiological Controlled Area thus requiring Offsite Dose Calculation Manual (ODCM) controls prior to discharge.
Prior to discharge the Cable Vault Sump is sampled. Licensed Radioactive Material entering the sump may be discharged using batch release methods if concentration and dose limits are maintained.
Typically, tritium is accounted for in monthly pre-release batch liquid effluent discharge permit. This sump discharges into the Unit 2 Catch Basin System at 2CB-4. Upon completion of filling operation, the sump must be recirculated a minimum of two (2) volumes prior to sampling for discharge permit preparation. -END-Beaver Valley Power Station Procedure Number: 1/2-0DC-2.01 Title: Unit: Level OfUse: 1/2 General Skill Reference ODCM: LIQUID EFFLUENTS Revision:
