I am J.M.Pugsley.I am employed by Florida Power&Light Company.as a Power Resources Specialist. A resume of my professional qualifications and experience is attached and made a part of this testimony. The purpose of this testimony is to address Contention 5 which states: In evaluating the steam generator repair, the following has'ot been considered: a.the cost of'full-flow condensate polishing demineralizing system; 0 t g b.the effluent release from a full-flow condensate polishing demineralizing system;or c.the environmental degradation caused by a full-flow condensate polishing demineralizing system.INTRODUCT ION In, addressing Contention 5, we will describe the proposed full-flow condensate polishing demineralizer system;describe how it operates;discuss the reasons why it is being installed; discuss why FPL does not believe it to be appropriate to'include a consideration of the condensate polishing demineralizer system in this proceeding; and demonstrate that nevertheless adequate consideration has been given to the condensate polishing demineralizer system in this proceeding, including the cost of;, effluent release from, and any environmental degradation anticipated to be caused by the proposed system.DESCRIPTION OF THE SYSTEM'ful'l flow condensate polishing demineralizing system-provides continuous on-stream filtering and demineralization of water that is circulated through the secondary side of the steam generators. Undissolved solid particles, as well as dissolved solids in the condensate are removed by this system. 1I The condensate polishing demineralizer system for each of the Turkey Point units (Units 3 and 4)is of the Powdex filter type, manufactured by Ecodyne Corporation, Graver Water Division, 2720 U.S.Hwy.No.22, Union, N.J.07083.The system consists of a group of filter/demineralizer vessels which use Powdex ion exchange materials, which are special.preparations of ion exchange resins in finely divided forms.Removal of the solid particles is accomplished by the filtering action of the demineralizer medium.Suspended impurities such as copper oxides, iron oxides, nickel oxides, and silica are removed by the filtering process.Removal of the dissolved solids is accomplished by ion exchange activity, in which metal cations in the water are replaced with hydrogen or ammonium ions (cation exchange)and anions in the water are replaced by hydroxyl ions (anion exchange). Dissolved solids in the form of cations such as magnesium, sodium, calcium, copper, iron and nickel, and anions such as sulphate, chloride, and dissolved silica are removed by an ion exchange process.Periodic replacement of the resins will be required due to a buildup of suspended solids and/or exhaustion of the ion exchange sites of the resins.To facilitate replacement of the resins, the condensate poli:shing demineralizer system includes precoat and spent resin hand'ling subsystems. The precoat subsystem is used to evenly distribute.powdered resins.across 0 il I the resin retention elements within the filter demineralizers. The spent resin handling subsystem is used to collect, process and discard exhausted resins out of the filter demineralizers. DESCRIPTION OF SYSTEM OPERATION When in use, the condensate polishing-demineralizer system will treat condensate flow discharged from the condensate pumps.The system may also be operated during feedwater recirculation and secondary system wet layup operation. The system design features filter demineralizer vessels in parallel that are normally used at their design flow rate.At lower flow rates either one or more vessels may be used.Flow'ontrol valves for the system will automatically divide the flow among the vessels in service.A total of eight vessels will be employed for, both Units, four per Unit,, three operating at a given time, with one per Unit in reserve.In the precoat subsystem, resin is manually loaded into the precoat tank where it is mixed'i'th demineralized water.The resin slurry is pumped to a filter/demineralizer vessel, where the resin is retained on the resin retention media by flow through the vessel.Mater used in'he precoat operation returns to the precoat pump suction, combines with the incoming resin slurry from the precoat tank, and is returned to the filter/demineralizer unit.The maximum loading is approximately 300 pounds per resin vessel per backwash cycle. II tt The spent resin handling subsystem is designed to function as follows.Pre-coated powdered resin is periodically flushed off the filter elements using condensate quality backwash water.The resulting water-resin slurry is collected in a backwash receiver tank.The first phase of solid and liquid separation occurs in the backwash tank as the denser solid material settles to the bottom of the tank due to gravity.This separation process results in a dense resin-water slurry at the bottom of the tank, and approximately 6000 gallons of supernatant liquid to be discharged for each backwash cycle.The solids are removed from the tank and collected in containers by use of a pressure filter.Before the supernatant liquid is discharged into the facility cooling canal system, it is filtered to less than 1 micron.The result is that the discharge will be a high quality liquid with a pH predicted to be between 8.5 and 8.7, a conductivity about 1 umho/cm , and a total solids concentration of well below the low volume waste source limits'40 CFR g423.22-100 mg/1 instantaneous max., 30 mg/1 monthly average).In other words, the quality of the water discharged is expected to be superior to that contained in the cooling canals.During normal operation, each unit will average one backwash cycle per week.Operation of the condensate polishers at Turkey Point Units 3 6 4 will result in Powdex material usage of approximately 57,000 lbs/yr. ll Normally, the contents of the backwash receiver tank will contain no plant-related radioactivity. Under these circumstances, the supernatant liquid may be discharged to the facility cooling system in the normal manner.The solid powder material is not discharged to the cooling system.It is removed from the system as a dewatered solid which is non-toxic and suitable for land burial., For each backwash cycle, approximately 6000 gallons of supernatant liquid will be discharged, at a rate of approximately 15 GPM, into the cooling system at the discharge basin.Flow through the discharge basin due to forced pumping is approximately 1.8 x 10 GPM with all pumps running.Consequently, since the flow rate of the discharge stream is only about 0.0008%of the flow rate of the receiving stream, adequate mixing is provided.The secondary systems are continuously monitored for any evidence of a primary to secondary leak.In addition, the steam generators are sampled and analyzed for radioactivity on a daily basis.In the event there is evidence of primary to secondary leakage, or radioactivity is detected in a steam generator, the backwash tank contents will be sampled and handled in accordance with Turkey Point procedures, Technical Specifications, and applicable NRC regulations for liquid or solid radioactive materials. REASON FOR INSTALLATION Beginning in mid-1978, FPL authorized expenditures for various plant improvements, including the installation of 4l 4k condensate polishing demineralizers, which are designed to im-prove secondary water chemistry control, for all of its nuclear plants.These improvements were directed to be implemented, and are currently being implemented in the Company's operating nuclear power plants at St.Lucie and Turkey Point, consistent with procurement lead times and planned unit outages.These improvements are also being incorporated into the design of the Company's nuclear power plant which is presently under construc-tion at St.Lucie.The decision to implement these improvements was made independent of the decision to repair the steam generators at Turkey Point Units 3 and 4.REASON FOR NOT CONSIDERING INSTALLATION OF CONDENSATE POLISHING DEMINERALIZER SYSTEM AS PART OF STEAM GENERATOR REPAIR PROJECT The Steam Generator Repair Report initially did not discuss installation of the condensate polishing demineralizer system.As set forth above, FPL's decision to install the condensate polishing demineralizer system was made independent from its decision to repair the steam generators at Turkey Point.The condensate demineralizers have utility independent of the repairs, and they will be installed whether or not the repairs are approved, and independent of the repair schedule.Consequently, FPL believes that installation of the condensate polishing demineralizer system for'Turkey Point Units 3 and 4 is not within the scope of the Steam Generator Repair Project.However, in Revision 7 to the SGRR, p.A-20-1, the II I, condensate polishing demineralizer system is discussed. And, as indicated'below, adequate consideration has been given by the NRC Staff in this proceeding. to the condensate polishing demineralizer system.CONSIDERATION OF SYSTEM Adequate considerati:on has been given by the NRC Staff in this proceeding to the economic and envi:ronmental costs, of, effluent release from, and any environmental degradation anticipated to be caused by the condensate polishing demineralizer system.The system, including these items, is discussed'n Sections 2.2 and 3:.2.4 of the Updated Safety Evaluation Repor't (NUREG-0756), in the NRC Staff"Assessment of the Impacts of the Steam Generator Repair Program at the Turkey Point Plant on Threatened or Endangered Species", pp.6, 7, U.S.Nuclear Regulatory Commission, Office of Nuclear Reactor Regulati'on (November 1980), and in Sections 4.2, 4.3.3, 4.3.4 and 6 of the Fi.'nal Environmental:Statement (NURFG-0743).As set forth in those documents., and in this testimony: A.Cost-The estimated'ost of the condensate polishing'demineralizer system for both units is$9,,000,000. B.Effluen'ts:: During norma'1 operati'on, liquid effluents due to discharge of supernatant liquid from backwash cycles of the system wi'll result in.the discharge to ll J t the cooling canal system of water having higher water quality than that of the cooling canals, and solid waste consisting of a, concentrated slurry suitable for land burial.If sampling of the liquid contents of the backwash receiver tank indicates levels of radioactivity which require handling as a radioactive liquid, appropriate steps will be taken before release into the cooling canal system in accordance with plant technical specifications and written procedures. Similarly, if solids from the backwash receiver tank are found to contain radioactivity in excess of regulatory limits, disposal will be by shipment offsite to a licensed burial ground in accordance with applicable NRC regulations for the disposal of low level solid waste.C.Environmental De radation: As set forth above, neither the operation of the condensate polishing demineralizer system, nor the effluents resulting from periodic backwash cycles, will cause any environmental degrada-tion or any adverse environmental impact.FURTHER AFFIANTS SAYETH NOT.Date~.l 0 y9&'.J~GOULD M G EY STATE OF FLORIDA))SS.COUNTY OF DADE)of SWORN to and subscribed before me this A~day 1981.Notary Pu lic My Commission Expires:~{eA.lY P{{Q{{Q c'y g{:{{~~.0~{{0{{PRO Vt{RU{!AY{VI{{0 {{c~/GAL y 0.~ Name: Position: Education: Summary: Experience: A.J.Gould Radwaste and Radiochemistry Specialist AA, Science Presently enrolled at Florida International University completing upper class course work in Industrial Engineering Technology Florida Power 8 Light Company 9 Years General Office Staff Radwaste and Radiochemistry Specialist-1 Year Nuclear Water Chemistry Specialist -1 Year Nuclear Water Chemistry Coordinator -2 Years Turkey Point Nuclear Plant Plant Coordinator -Nuclear Chemistry-4 Year Associate Plant Coordinator -Nuc.Ch.->Year Plant Test Engineer-Nuclear Chem.-1 Year Plant Technician -Nuclear Chemistry-1 Year United States Navy, Nuclear Submarine Serv.-8 Years Leading Engineering Laboratory Tech.-4 Years Engineering Laboratory Technician -3 Years Mr.Gould is employed as a specialist on the General Office Staff of the Power Resources Department.
