3.0 DEFINITIONS
[1]
Chlorination or hypochlorination - Injection of liquid sodium hypochlorite solution into raw cooling water to prevent or control marine growth, both microfouling and macrofouling.
[2]
Total Residual Chlorine (TRC) - The concentration of all oxidants in a solution of chlorinated seawater which, at pH 4, cause added iodide to be converted to iodine.
Amperometric titration with phenylarsine oxide is the analytical method approved by US EPA, with the results converted to mg/liter
(= ppm) of chlorine; equivalent to total residual oxidant (TRO).
4.0 DISCUSSION 4.1 GENERAL
[1]
The purpose of the chlorination system is to prevent or control marine growth (biofouling) within those cooling systems (CWS and SSWS) which use seawater as a heat sink.
Excessive biofouling can reduce heat transfer efficiency, restrict cooling water flow, and accelerate corrosion/erosion of affected components. There are two basic aspects of chlorination:
hypochlorite injection and residual chlorine monitoring.
Chlorination is achieved by adding a solution of sodium hypochlorite separately to the CWS and SSWS. The hypochlorite injection apparatus for each
-is located in the Screenhouse and Intake Structure. A lined-steel hypochlorite storage tank (T-147) common to both CW and SSW chlorination subsystems has a capacity of 14,000 gallons and reads out in inches of water.
.,Tank level is monitored daily by Operations in accordance with PNPS 2.1.16,
"'Nuclear Power Plant Operator Tour". When T-147 level drops to 50 inches as indicated on 28-LI-3990, Operations will notify and schedule vendor delivery and refill of sodium hypochlorite in accordance with PNPS 1.12.1, "Receiving, Recording, and Monitoring of Consumable Deliveries".
Monitoring of discharged chlorine concentration, measured as total residual chlorine (TRC), is conducted by Chemistry.
[2]
The Screenwash Dechlorination System is intended to comply with the US EPA requirement that the screenwash water contain no residual chlorine. The water used to spray the traveling screens comes from the SSWS (which normally is continuously chlorinated); therefore, the screenwash water usually must be dechlorinated when either/both screenwash pump(s) is operated.
2.2.95 Rev. 52 Page 7 of 66
4.2 CIRCULATING WATER SYSTEM CHLORINATION 4.2.1 CW Hypochlorite Injection - Description
[1]
Target: Microfouling (slime or biofilm) accumulation in the Main Condenser.
Not intended to control biofouling in the Intake Structure.
[2]
Frequency: Condenser chlorination is governed by the MSTP and varies according to the time of year.
CW hypo is usually done 5 to 7 days per week (for 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />s/day) during the spring, summer, and fall. The frequency is usually reduced in the winter to reflect the decrease in microbial growth.
4.2.2 CW Hypochlorite Injection - Function
[1]
Operation: Chlorine is introduced into the CWS by pumping hypochlorite into diffusers located underwater, upstream of each of the four traveling screens.
Two hypo pumps (P-113A and P-113B) draw filtered hypochlorite from the storage tank (T-147) and inject it into separate dilution lines supplied with screenwash water, which discharge into the four CW hypo diffusers.
Chlorinated intake water is then dispersed into the CW pump bays and delivered to the condenser by the CW pumps.
[2]
Control:
Each CW hypo pump is operated by a control switch on Panel C38 and a handwheel to adjust the pump stroke. The two control switches have four positions:
"CONTINUOUS", "MANUAL", "AUTO", and "OFF"; however, only the "CONTINUOUS" mode is used to activate P-113A/P-113B. The "MANUAL" and "AUTO" modes are not normally used and their function is not addressed in this Procedure.
Hypo injection rate (pump output) for P-113A/P-113B is controlled by the adjustment handwheel which changes the length of the pump piston stroke: the frequency is fixed at 140 strokes/minute. An "odometer style" scale, which ranges from 0000 - 0400, indicates the relative stroke length up to a maximum rated capacity of 5 gallons/minute. Actual hypo injection rate is determined by reading the in-line flow meters downstream of each hypo pump.
2.2.95 Rev. 52 Page 8 of 66
[3]
Electrical Isolation: It is strongly suggested that both CW and SSW hypo injection subsystems not be isolated at the same time.
Whenever possible, avoid developing a tagout which isolates the common breaker (14L-12). The following guidance should be referred to when it is necessary to isolate the CW hypo subsystem.
CW hypo injection equipment receives electricity from 120V AC and 480V AC power sources. Breaker #12 in Lighting Panel 14L supplies 120V AC control power to both CW hypo (Panel C38) and SSW hypo (Panel C37).
It is desirable to avoid de-energizing Panel C37 (SSW hypo injection) when isolation of only C38 is needed.
To de-energize the CW hypo control panel independently of C37, use the toggle switch/breaker located within Panel C38.
This switch/breaker has two positions (ON/OFF) and is labeled C38-CB1.
Use the CW hypo pump (P-113A/P-113B) control switches on C38 and/or the 480V AC power supply to isolate the CW hypo pumps.
Breaker 13/15/17 in Panel 13L supplies 480V AC (3-phase) power to P-113A and P-113B. The circuit is arranged so that this triple pole breaker feeds two panels: B26A (to pump P-113A) and B26B (to pump P-113B).
4.2.3 CWS Residual Chlorine Monitoring Measurement of the concentration of total residual chlorine (TRC) in the CWS is requtred by NPDES (National Pollutant Discharge Elimination System) stipulations.
The unit of measurement identified in the NPDES permit (mg/liter total residual oxidant-or mg/L TRO) is equivalent to parts per million (ppm) total residual chlorine (TRC). Monitoring instrumentation consists of a sample pump at the discharge canal footbridge and an amperometric titrator to determine the TRC concentration in samples drawn from the effluent stream.
PNPS 7.2.40 addresses this issue-.c-mpletely; however, Chemistry should be notified of any CWS change that has the potential to impact system performance and/or the concentration of TRC discharged.
2.2.95 Rev. 52 Page 9 of 66
4.3 SALT SERVICE WATER SYSTEM CHLORINATION 4.3.1 SSW Hypochlorite Injection - Description
[1]
Target: Macrofouling (especially mussels) in the SSW pump bays, piping, and RBCCW/TBCCW heat exchangers. Microfouling in the SSWS is also controlled as a consequence of chlorination.
[2]
Frequency:
Normally continuous, every day, year-round.
4.3.2 SSW Hypochlorite Injection - Function
[1]
Operation:
The SSWS is chlorinated by injecting hypochlorite into diffusers submerged in the SSW pump bays. Three hypo pumps (P-161A, P-161B, and P-161C) draw filtered hypochlorite from the storage tank (T-147) and inject it into separate dilution lines supplied with city water, which discharge into hypo diffusers adjacent to the SSW sluice gate openings. The chlorinated service water is then dispersed into the SSW pump bays and delivered to the SSWS by the SSW pumps.
[2]
Control: The SSW hypo pumps (P-161A, P-161B, and P-161C) are activated by control switches on Panel C37 and adjusted by a pair of knobs on each pump which regulate stroke length and frequency.
The control switches for P-161A and P-161B have four positions:
"CONTINUOUS", "MANUAL", "AUTO", and "OFF";
however, only the "CONTINUOUS" mode is used to activate P-161A/P-161B. The "MANUAL' and "AUTO" modes are not normally used and their function is not addressed in this Procedure. The control switch for the "swing" SSW hypo pump (P-161C) is located in the center of Panel C37 and only has two positions; "STOP" and "RUN". P-161C is usually only operated as a backup when one of the other two pumps is unavailable.
Hypo injection rate (pump output) for P-161A, P-161B, and P161C is controlled
-by turning either the-"percent-stroke" (length) and/or "stroke rate" (frequency) adjustment knobs. The pump manufacturer recommends maintaining the maximum possible stroke length for a given combination of stroke length and stroke frequency (i.e., increase "percent stroke" first when raising the injection rate).
The sightglasses downstream of the SSW hypo pumps only offer a visual (qualitative) indication of hypo flow. Adjustment of the SSW hypo pumps is based on measurement of total residual chlorine (TRC) concentration in the SSWS, conducted by Chemistry.
[3]
Electrical Isolation: Because of the need to continuously chlorinate the SSWS to prevent mussel infestation, isolations for the SSW hypo subsystem should be carefully selected to minimize impact on component availability.
Breaker #12 in Lighting Panel 14L supplies 120V AC power to both SSW hypo (Panel C37) and CW hypo (Panel C38). It is desirable to avoid de-energizing Panel C38 (CW hypo injection) when isolation of only C37 is needed.
To de-energize the SSW hypo control panel independently of C38, use the toggle switch/breaker located within Panel C37.
This switch/breaker has two positions (ON/OFF) and is labeled C37-CB1.
Use the SSW hypo pump (P-161A/P-161B/P-161C) control switches on C37 and/or unplug the 120V AC power supply to isolate individual SSW hypo pumps.
2.2.95 Rev. 52 Page 10 of 66
4.3.3 SSWS Residual Chlorine Monitoring Data on TRC levels in each loop of the SSWS are obtained from daily grab sampling and analysis (by amperometric titration) performed during chlorination.
Chemistry should be notified of any SSWS change that has the potential to impact system performance and/or the concentration of total residual chlorine (TRC) discharged.
4.4 SCREENWASH WATER DECHLORINATION The screenwash water is dechlorinated by injection of saturated sodium thiosulfate solution into the suctions of each screenwash pump.
Whenever the screenwash pumps are operated, the dechlorination pumps start automatically, drawing a suction from the respective sodium thiosulfate drums.
System flow is monitored at each pump discharge by a bubble type flow indicator.
Pump stroke length and stroke rate are each controlled by rotary dials (0-100%).
Dechlorination pump operation secures automatically upon stopping the associated screenwash pump and may be manually secured by placing the pump control switch to "STOP". The Dechlorination System should be aligned for automatic operation by leaving the control switch for P-175A and P-175B in the "START" position, unless the CW and SSW Chlorination systems are secured for an extended period.
An event recorder documents the operation of the four traveling screens, the screenwash pumps, and the dechlorination pumps as part of the marine biota impingerent monitoring program required by the NPDES permit.
If chlorination is performed while a screenwash pump is operating, then dechlorination of the screenwash water is required. If thorough dechlorination is not possible (as determined by Chemistry), then both CW and SSW hypo injection systems-,~shall be secured while there is water flowing through the sluiceway (i.e.,
when either screenwash pump is operating).
2.2.95 Rev. 52 Page 11 of 66
5.0 PRECAUTIONS AND LIMITATIONS 5.1 PRECAUTIONS
[1]
Sodium hypochlorite is corrosive and causes chemical burns when touched.
Avoid physical contact with skin, eyes, and clothing. Appropriate personal protective safety equipment shall be utilized whenever activities are in progress that have the potential to expose an individual to sodium ypochlorite.
(PR99.9027) Refer to the MSDS (Material Safety Data Sheet) for guidance when handling this substance.
(a) When traversing the hypochlorite pump room, normal PPE (hard hat, safety glasses, leather shoes) is sufficient.
(b) When operating equipment for hypochlorite (valving, stroke adjustments, starting/stopping equipment, draining, or connecting/disconnecting flex hose or any activity which has the potential for a spill), personnel shall utilize full PPE:

7.0 PROCEDURE NOTES
- 1.
Chlorination (hypochlorite injection) of both CWS and SSWS is covered in this Procedure as follows:
Section 7.1 for CW Chlorination, Section 7.2 for SSW Chlorination, Section 7.3 for Screenwash Dechlorination (also addressed in PNPS 2.2.94).
- 2.
Chlorination of the SSWS should be continuous (24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />s/day) to control mussel growth (macrofouling) in the SSW pump bays, heat exchangers, and piping.
Instantaneous TRC limit in the SSWS is 1.00 ppm, measured before mixing with the CWS flow.
- 3.
CW chlorination is done for 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> every day (or twice/week in winter) to prevent microfouling (slime buildup) from affecting condenser performance.
Instantaneous limit for total residual chlorine (TRC) is 0.10 ppm measured in discharge canal. Refer to Section 5.2 for more information on limitations.
- 4.
If thorough dechlorination of the screenwash water is not possible (as determined by Chemistry), then both CW and SSW hypo injection systems shall be secured when either screenwash pump (P-213A/B) is operating.
2.2.95 Rev. 52 Page 14 of 66
7.1 CHLORINATION OF THE CWS (CONDENSER) USING THE CW4HYPO PUMPS NOTES
- 1.
Chlorination of CW pump bays may be done in any order (i.e.. Section 7.1.3 may be done before Section 7.1.1). Alternate which bay is done first as much as possible (try not to start with the same bay every day). It is not permissible to chlorinate both CW pump bays simultaneously.
- 2.
Hypo injection is normally done for 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> per CW pump bay (2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />s/day).
It may be less than this but not more than 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> total duration per day (e.g., a single CW pump may be chlorinated for up to 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> at a time).
- 3.
Both seawater (CW) pumps should be operating prior to and during CW hypo injection. If either CW pump is secured during hypochlorination, then immediately secure hypo injection as well.
- 4.
When only one CW pump is in operation, there is an increased risk of overchlorination.
Do not perform hypochlorination with only one CW pump running unless:
- a. Permission is obtained from both the SM and the Chemistry Superintendent.
- b. Sea conditions near the mouth of the discharge canal must be less than 2 feet (no storm surges).
- 5.
The Operator shall control hypo injection so that the discharge limit of 0.10 ppm TRC (total residual chlorine) is not exceeded.
Once hypochlorination is underway, upon receiving feedback from the Chemistry Technician, the injection rate may be increased in gradual steps provided that the following conditions are met:
- a. An achievable limit concentration has been established in PNPS 7.8.1, "Chemistry Sample and Analysis Program", to avoid overchlorination.
This target value may be exceeded, but only with the approval of the SM/CRS and Chemistry Supervision.
- b. Start hypochlorination based on the initial hypo injection rate specified by the Chemistry Technician. A waiting period of at least 20 minutes shall be observed prior to any increase in the hypo injection rate when two CW pumps are operating. If only one CW pump is in service, then a waiting period of at least 40 minutes app lies prior to increasing the hypo injection rate.
- 6.
It is very important that two-way communication can be established throughout the entire injection process. In case of a problem, the only way the Operator knows to reduce or secure hypo injection is by feedback from the Chemistry Technician. In case of loss of communication, secure hypo injection or use the Gaitronics private line until normal communication is restored.
- 7.
When the level in the hypo storage tank (T-147) goes below 50 inches (using LI-3990), then more sodium hypochlorite should be ordered.
Contact the Control Room Annex to reorder hypo and fill in accordance with PNPS 1.12.1, "Receiving, Recording, and Monitoring of Consumable Deliveries".
2.2.95 Rev. 52 Page 15 of 66
7.1.1 Operation Of CW Hypo Pump P-113A
[1]
CHECK the oil level in P-113A AND ENSURE it is within the acceptable range indicated on the dipstick.
[2]
VERIFY that the CW (seawater) pump is operating in the bay to be chlorinated.

7.2 CHLORINATION OF THE SSWS NOTES
- 1.
SSW hypochlorination should be maintained within the achievable limits of PNPS 7.8.1.
- 2.
Normally. hypochlorite is continuously injected into the SSWS.
- are certain situations which require that the SSWS hypochlorite system be secured:
However, there injection Inability to sample/measure the residual chlorine level in the SSWS prior to mixing with any other stream.
Inability to completely dechlorinate the screenwash water when a screenwash pump must be operated.
No CWS flow in discharge canal (for dilution), usually because there is a Main Condenser backwash or because no CW (seawater) pumps are operating.
Dive operation underway in SSW pump bay.
There may be other reasons for terminating SSWS chlorination, but these are the most common causes.
- 3.
Operation and control of the SSW hypo injection subsystem is dependent on several variables including SSWS configuration, dechlorination system status, and TRC level in the SSW System. In order to avoid excessive chlorination (and NPDES Permit violations), it is essential to maintain timely communication between Operations and Chemistry personnel.
- 4.
The following sections may be performed in any order deemed acceptable by the SM/CRS.
2.2.95 Rev. 52 Page 28 of 66
r CAUTIONS
- 1. Be careful not to overchlorinate. The EPA limit for maximum SSWS chlorine level is 1.00 ppm TRC (total residual chlorine) for both SSW loops averaged together.
However, the TRC average for both level in the "A" then this is not exceed 1.00 ppm.

Sheet 1 of 4 CWS HYPOCHLORITE INJECTION MONITORING NOTES
- 1.
Chlorination of CW pump bays may be done in any order (i.e., base document Section 7.1.3 may be done before Section 7.1.1). Alternate which bay is done first as much as possible (try not to start with the same bay every day).
It is not permissible to chlorinate both CW pump bays simultaneously.
- 2.
Hypo injection is normally done for 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> per CW pump bay (2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />s/day).
It may be less than this but not more than 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> total duration per day (e.g.. a single CW pump may be chlorinated for up to 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> at a time).
- 3.
Both seawater (CW) pumps should be operating prior to and during CW hypo injection. If either CW pump is secured during hypochlorination, then immediately secure hypo injection as well.
- 4.
When only one CW pump is in operation, there is an increased risk of overchlorination.
Do not perform hypochlorination with only one CW pump running unless:
- a. Permission is obtained from both the SM and the Chemistry Superintendent.
- b. Sea conditions near the mouth of the discharge canal must be less than 2 feet (no storm surges).
- 5.
The Operator shall control hypo injection so that the discharge limit of 0.10 ppm TRC (total residual chlorine) is not exceeded. Once hypochlorination is underway, upon receiving feedback from the Chemistry Technician, the injection rate may be increased in gradual steps provided that the following conditions are met:
- a. An achievable limit concentration has been established PNPS 7.8.1, "Chemistry Sample and Analysis Program", to avoid overchlorination.
This target value may be exceeded, but only with the approval of the SM/CRS and Chemistry Supervision.
- b. Start hypochlorination based on the initial hypo injection rate specified by the Chemistry Technician. A waiting period of at least 20 minutes shall be observed prior to any increase in the hypo injection rate when two CW pumps are operating. If only one CW pump is in service, then wait at least 40 minutes prior to increasing the hypo injection rate.

NOTES (Continued)
- 6.
It is very important that two-way communicatioh-llan be established throughout the entire injection process.
In case of a problem, the only way the Operator knows to reduce or secure hypo injection is by feedback from the Chemistry Technician. In case of loss of communication, secure hypo injection or use the Gaitronics private line until normal communication is restored.
- 7.
When the level in the hypo storage tank (T-147) goes below 50 inches (using LI-3990), then more sodium hypochlorite should be ordered. Contact the Control Room Annex to reorder hypo and fill in accordance with PNPS 1.12.1, "Receiving, Recording, and Monitoring of Consumable Deliveries".
- 8.
Check FG-39043 hypo storage tank T-147 leak detection sightglass, located below the hypo storage tank, to verify no liner leakage exists.

-OF CW Pump B Note: Record CW hypo pump settings and flow rate (GPM) every 10 minutes. Circle which hypo pump used (P-113A or P-113B) below.
Maintain communication with Chemistry Technician and record TRC readings. If chlorine discharge level is exceeded, terminate hypo injection and notify the CRS/SM immediately. Review base document Precaution Step 5.1[1] for PPE requirements.
NOTE In attempt to equalize run times and prevent sodium hypochlorite from coming out of solution and causing flow indicator fouling, use P-113A to inject hypo into the "A" CW Pump (if available). Use P-113B to inject hypo into the "B" CW Pump (if available). If either CW hypo pump is not available, use the cross-tie to inject into the opposite CW pump.
