4.2 Forms 4.2.1 None 5.0 PRECAUTIONS AND LIMITATIONS 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 unit's 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. <3.1J.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 ofBV-1 and BV-'2 is described as follows:

5.2.3.1 HIGH and HIGH-HIGH terminology are used for BV-1 monitors and ALERT and HIGH terminology is used for BV-2 monitors.

5.2.3.2 BV-1 alarm setpoint units are expressed as counts per minute (cpm) and BV-2 alarm set'points 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.

5.2.4 This procedure also contains information that was previously contained in Section 5 of the previous BV-1 and 2 Offsite Dose Calculation Manual.

[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. (3.1.1.4) 8.1.1.1.5 BV-1 Monitor HHSP 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.

8.1.1.2 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.

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.

8.2.l Batch Releases 8.2.1.l Pre-Release The radioactivity content of each batch release will be determined prior to release in accordance with l/2-0DC-3.03, Table 4.11-1. 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 l/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:

BV-1 and 2 utilize the concept of a shared liquid radioactive waste system according to NUREG-0133. (3.1.3.l) This permits mixing of the liquid radwaste for processing. Since the resulting effluent release cannot accurately be attributed to a specific reactor unit, the treated effluent releases are allocated as defined below.

The dose contribution from the release of liquid effluents will be calculated monthly for each batch release during the month and a cumulative summation of the total body and organ doses will be maintained for each calendar month, current calendar quarter, and the calendar year to date. The dose contribution will be calculated using the following equation:

A table of Ai, values for an adult at BV-1 and BV-2 are presented in ATTACHMENT B Table 1.3-1.

The far field dilution factor (Dw) for BV-1 and BV-2 is 200.

The total dilution factor of 600 represents a conservative fully mixed annual average condition. Since the Midland intake is located on the opposite bank and is below the water surface, essentially fully mixed conditions would have to exist for the radioactive effluent to be transported to the intake.

However, this evaporator was retired prior to initial issue of the ODCM, because of concerns for creating a mixed-waste. SINCE the evaporator is no longer in-use, THEN it is not shown on Figure 1.4-1 in ATTACHMENT C.

8.4.1.8 [1LW-TK-7A/B], STEAM GENERATOR DRAIN TANKS There are two (2) of these tanks, each tank has a nominal capacity of 34,500 gallons (maximum capacity= 35,800 gallons). They are located in the Fuel Pool Leakage Monitoring Room (elevation 735'). They normally rec~ive liquid waste that has been processed through the liquid waste demineralizer. These tanks can also receive liquid waste from Unit 2. Upon completion of filling operation, the tank is placed on recirculation through the demineralizer until the radioactivity concentration is acceptable for discharge. A minimum of two (2) tank volumes must be recirculated prior to sampling for discharge permit preparation.

8.4.1.9 [RM-lLW-104], LIQUID WASTE DISCHARGE RADIATION MONITOR An off-line gamma scintillator radiation monitor continuously analyzes liquid waste as it is being discharged. The normal rate of discharge through this radiation monitor from [1LW-TK-3A/B], LOW LEVEL WASTE TANK DRAIN TANKS and [lLW-TK-7A/B] is less than thirty-five (35) gpm. The normal rate of discharge through this radiation monitor from [1BR-TK-4A/B], COOLANT RECOVERY TANKS is less than 50 gpm. The high alarm on this radiation monitor has a setpoint that would indicate liquid waste discharges that are approaching OEC limits. If a high high alarm is received, liquid waste discharge is automatically terminated by closing the discharge line isolation valve.

ODCM: LIQUID EFFLUENTS 17 28 of 43 8.4.1.11 [lLW-RWR0-1], RAD WASTE REVERSE OSMOSIS 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-1-3], 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/B], COOLANT RECOVERY TANK being processed from. This skid is located in the Solid Waste Building (elevation 735'-6").

8.4.1.12 [lLW-I-3-5], ANTIMONY VESSEL

[lLW-I-3-5], ANTIMONY VESSEL is a two (2) cubic foot ion exchange vessel placed downstream of the [lLW-RWR0-1], RAD WASTE REVERSE OSMOSIS SKID. This vessel removes antimony isotopes from the reject stream of the [lLW-I-3-5] prior to discharge back to the [1BR-TK-4A/B], COOLANT RECOVERY TANK being processed from. This skid is located in the Solid Waste Building (elevation 735'-6").

8.4.1.13 [lLW-I-3-6], POLISHING VESSEL

[lLW-I-3-6], POLISHING VESSEL is a fifteen (15) cubic foot ion exchange vessel placed downstream of the [lLW-RWR0-1], RAD WASTE REVERSE OSMOSIS SKID. This skid is located in the Solid Waste Building (elevation 735'-6").

8.4.1.14 Sample Sinks The sample sinks allow sampling at both influent and effluent vessel streams. In addition, the sinks include gauges that indicate the pressure at each sample point.

One sample sink is located locally (Solid Waste Building - elevation 735'-6") to the system and allows for sampling from eight (8) individual points within the system.

A second sample sink is remotely located and contains four (4) sampling points (Primary Auxiliary Building - elevation 768'-7" along the east wall). A sample sink is also included on the [lLW-RWR0-1], RAD WASTE REVERSE OSMOSIS (RWRO) SKID to provide sample points from within the skid itself.

17 31 of 43 8.4.4 BV-1/2 Miscellaneous Sumps 8.4.4.1 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.

ODCM: LIQUID EFFLUENTS 17 32 of 43 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 non-radiological liquid waste. It is used for the collection and release of non-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.
