2.2.2 Added Process Chemicals Objective The purpose of this specification is to limit discharges of Chromium, Boron, Phosphate, and Sulfate to the ocean environment.
Specification The annual (calendar year) discharge of chemicals to the cir culating water system shall not exceed the following limits without prior approval from the NRC.
Chromium:
1,000 lbs of K 2Cr04 Boric Acid:
170,000 lbs of H3 BO
.Na 2 04 Phosphate:
5,400 lbs of Na2 PO4 Na PO
- 3. 4 Sulfate* Calendar Year 1979 -
1,785,000 lbs. of H2 SO4 Calendar Year 1980 -. 2,350,000 lbs. of !12 S04 Calendar Years Beginning 1381 90,000 lbs.*of H2 SO4 Monitoring Requirements Inventory records of the usage of Chromium, Boron, Phosphate, and Sulfate shall be maintained to provide a record of the usage-of these chemicals.
Bases Chromium is utilized in the component cooling water and turbine plant cooling water systems in the form of potassium chromate.
Loss from the sy-stems is through leakage only.
Complete or partial draining of this system utilizes temporary retention tanks and does not result in direct release to the environment.
The limit established by the Specification provides for control of normal leakage and ensures system draining is not made to the environment.
Boron is utilized in the reactor coolant system as a neutron
.absorber.
During noral operations and plant shutdown with
- cooldowvfi the concentration of boron is varied as one means of controlling teactivity. This results in reactor water entering the radioactive waste system from where it is eventually re leased to the ocean environment.
The resulting maxiuea added concentration at the discharge of.75 ppm has not created an observ'ed envirormental impact.
The Specification provides ssurance that releases of Boron will not exceed those which have not impacted the environment in the past.
2-6 Amendment No. 41
Phosphates in the form of mono-, di-, and tri-sodium phosphate
-are added to the steam generators as a means oL controlling tube corrosion and deposit formation. Steam generator blow down is released at a continuous rate of up to 25 gpza.
The resulting added concentration of.075 ppm at the discharge has not.created an observed environmental impact.
The Specification provides assurance that releases of phosphates will not exceed those which have not impacted the environ.ment in the past.
Sulfates in the form of sulfuric acid are add.ed to the San Onofre Unit 1 flash evaporator to assist in corrosion control by maintaining pH less than 7.5.
The resulting maximum added concentration at the. discharge,
.073 ppm, has not created an observed environmental impact.
In addition, sulfuric acid is used in the regeneration of San Onofre Units 2 and 3 makeup demineralizers. Until the San Onofre Units 2 and 3 circulating water system is placed in service, neutralized regenerants with a final solution pH of 6.0 to 9.0 and a :aximum ad.ded concentration at the discharge of 16 ppm, obtained during the clea::in'g. flushing and startup of San Onofre Units 2 and 3 systems, are temporarily discharged directly to the San Onofre Unit 1 circulating water outfall tsunami structure.
Neutralized sulfuric acid (pH 6.0 to 9.0) has no deleterious effects on the ocean environment. In the remainder of the 1979 calendar year, 1,695,000 pounds of the total discharge limit of 1,735.000 pounds of
'H2SOz1 is discharged from San Onofre Units 2 and 3.
For the 1930 calendar
.4ear,.2,260.000 pounds of the total discharge limit of 2,350,000 pounds of H2 S04 is discharged from San Onorre Units 2 and 3.
When the San Onofre Units 2 and 3 circulating water system is placed in service, the discharge of sulfates in the form of sulfuric acid will be limited to
.hat added to the San Onofre Unit 1 flash evaporator (i.e., 90,000 P Dunds).
The specification provides assurance that releases of sulfat e ill not exceed those which have not impacted the environment in the past.
2.3 Radioactive Discare aos f or the controlled r'elease of radioactive liquids and gases shall-be as specified in Appendix A, Technical Specifications.
2-7 Amendment No. 41
TABLE 5.8-1. (Cont'd)
Maximum Added Maximum Added Concentration (ppm)
Chemical or Element Release (lb/day) at discharge Use and Frequency of Discharge Po-tasiwm 1,090 0.26 Included in 120 gpm continuous brine discharge from flash evaporator.
Sodium 30,200 7.2 Included in 120 gpm continuous brine discharge from flash evaporator.*
Sulfate 7.925 1.89 Included in 120 gpm continuous brine discharge from flash evaporatorh And includes addition of sulfuric acid used.
cn Sulfide 0.29 0.001 Included in 120 gpm continuous brine discharge from flash evaporitor.*
- rThin dicharge repronents concentrated ocean water resulting from a flash evaporation process, thus only concentrating constituents already present in the sea water.
This process provides the fresh water supply for the Station.
During the calendar years 1979 and 1980, the maximum added release (1b/day) and the maximum added concentration (ppm) at discharge is 14,250 and 17.9, respectively~from San Onofre Units 2 and 3 as de'scribed in Tcchniedl Specification 2.2.2.
