MAJOR CHANGE TO RADWASTE USE OF VECTRA ROVER" SYSTEM TO PROCESS FLOOR DRAIN, CHEMICAL FLOOR \

DRAIN, AND EQUIPMENTDRAIN WASTE STREAMS '

l I

The following information is being submitted in accordance with Technical Specification 6.9:

e 6.9.1.s.1 A sununary of the eunluation that ind to the determination that the change I could be made in accordance with 10 CFR 60.50; A copy of the approved safety evaluation (10 CFR 50.5g evaluation) is attached (See Attachment A). The evaluation is summarized as follows:  !

l A mobile vendor system (VECTRA) will be used to process water collected by the WF (Floor l Drain) and WZ (Chemical Drain) systems. The vendor system will be located in the South Intermediate Storage Area of the Radwaste Truck Bay (RWTB). The mobile vendor system will also be used to process concentrated wastes generated during the processsing of water from the WF and WZ systems. The mobile vendor system may be optionally used to process WE (Equipment Drain) water.

l Accident scenarios previously evaluated in the SAR are not impacted by this change because there are no changes to the operating conditions of piant equipment (pressures /femperatures) with respect to design criteria or applicable design codes. The mobile vendor system has been conservatively constructed to meet Reg Guide 1.143 requirements.

Accident scenarios introduced by use of the mobile vendor system are bounded by those presented in the UFSAR (especially 15.7.3).

e 6.9.1.a.2 - SutNclent detailed Inl6rmation to totally support the raason kr the change without beneRt or additional or supplementalinkrmation; Currently the station employs evaporators to process the WF and WZ waste streams. Annual maintenance of the evaporators imposes a significant radiation exposure burden on l Operating and Maintenance personnel. In addition, the evaporators generate a concentrated '

.- waste stream which must be solidified to meet applicable transportation and 'Espamal

regulations. Solidification is a relatively inefficient method of packaging solid waste with l respect to burial volume

! The mobile vendor system utilizes state of the art technology to process the waste streams.

, Effluent quality will meet existing specifications for Cycled Condensate (CY) water and is i assured by utilizing existing instrumentation which causes off-standard water to be shunted back to the Collector Tank.

The vendor system is fully automated and thereby minimizes operator radiation exposure.

j The system utilizes very few moving parts and therefore primary maintenance is expected to

involve the infrequent replacement of filter elements.

The mobile system generates a waste stream which will be processed via a field-tested i Radwaste. Volume Reduction (RVR) system. Processing through the RVR system produces j a dry powdery waste solid waste and is very efficient with respect to burial volume, i

i l

\

i -

e 6.9.1.a.3 - A detailed deecription of the equipment, componente, and proceanes involved and the Interiscoe with otherplant systems; A detailed desenption of the mobile vendor system is provided in Attachment B.

{

) The mobile vendor system will receive waste streams via piping installed under a station i Design Change (DCP 95000f40). The new piping receives feed from the WZ transfer pump

an can be cross-tied to receive waste from the WF system.

l Processed water is retumed to the station via paping installed under the same Design l Change. The new piping ties into existing distillate piping for.the 1WF Evaporator. The final j flowpath of the processed water is identical to the distillate of the evaporators.

i e 6.9.1.a.4 - An evaluation of the change which shows the predicted releneen of radianctive meteriale in liquid and gaseous elRunnte ancVor truantity of solid waste that dlNor ham those previously predicted in the lioenee application and amendments i thereto;

} The mobile vendor system will be processing existing liquid radweste streams and serves as I i a replacement for the evaporators. The new process configuration allows for the pic-:::::1 i water to be retumed to the station where it is then treated identical to the original evaporator distillate. There is no not change to the liquid affluent treatment. i The mobile vendor system is located in the station's South Intermediate Storage Area which i is subject to the Radweste Building Ventilation system (VW). All potential gaseous effluents will be handled by the VW system and thee is thersicro no not chanye to the gaseous

effluents as previously estimated in the license application. ,

i

' Solid waste produced from the mobile vendor systern will be packaged for disposal in accordance with the station's Process Control Program to ensure compliance with applicable transportation and disposal regulations. Total quantity of solid radwaste is e

expected to decrease given the greater peckeging efficiency of the vendor's RVR system. i

!- Since the liquid radwaste streams remain unchanged, the total retenactive quantity in the l resultant solid radwaste will remain consistent with the original license application quantities. )

f i l l e 6.9.1.a.6- An evaluation of the _ change which shows the e' xpected maximum

exposurme to individualin the umentrictedarme and to the generalpopulation that dlNor kom those previously estimated in the license application and amendments

thereto; The mobile vendor system will be located in the South intermediate Storage area which was originally designed to store 395 drums with dose rates in the 1.5 R/hr - 5 R/hr range. The mobile vendor system employs water and steel shielding to ensure that general area do;e rates in the area are maintained ALARA. (signficantlylower than f.S IMr). Since the dose rates in the room will be maintained significantty lower than the original design, expected l exposures to individuals in the unrestricted area and to the gerstal population are well below those previously estimated in the license application and amendments.

~

s e

6.9.1.s.6 - A comparison of the predicted releeson of radioactive materials, in liquid and gaseous ettluents arut in solid waste, to the actual retenees for the period to when the changen are to be made; Liquid effluent releases are unaffected by this change because the final processing configuration of the treated water remains unchanged.

Gaseous effluent releases are unaffected by this change because the vendor system is located in the Radwaste Building and therefore is subject to an existing ventilation system (VW).

A comparison between the existing annual solid waste generation (basedon 1993 -1995 data.) and predicted annual solid waste generation is as follows y g .7,-k. m ._' .[l .., 7 ,7 7, m w y ~ -

6.9.1.a.7- An estimate of the exposure to plant operating personnelse a result of the change; Operation of the mobile vendor system will replace the need for the evaporators and the associated annual dose costs for Evaporator Operatiorddaintenance. These dose costs are significant (25 - 40 Person-RerWYr). These dose costs are based on previous dose history of previous Evaporator Outages. These dose figures are conservative in that dose costs attributed directly to Evaporator Operation are not included. Operation / Maintenance dose costs for the mobile vendor system are projected as follows:

l d' . . 11.2 LIOUID WASTE MANAGEMENT SYSTEMS

The liquid radwaste system collects, monitors, and treats all

! potentially radioactive liquid wastes produced by the station

during normal operation and saintenance, as well as transient

! conditions.

i 11.2.1 Desion Bases -

11.2.1.,1 Safety Desion Basis

The liquid radwaste system is designed so that liquid radwastes i discharged from the site vill have radioactivity concentrations j vell withi'n limits specified in 10 CFR 20 and meet the design j objec.tives of 10 CFR 50, Appendix I.

) Each liquid radwaste stress terminates in a sample tank. 'Since

the liquid radwaste systes operatos on a batch basis, this i arrangement allows each treated batch to be sampled when appropriate to assure that,the treatment was effective. If the ,

l sample indicates that the waste needs,further processing, it is l' l recycled either through the same treatment or through a subsysten providing a highe.r degree of treatment. If the treated. waste  !"

water is not needed for recycle, the water is sent to the discharge tank and held until a discharge batch is accumulated. l

'~

Each batch is sampled to verify that its activity level is within i limits for discharge. The actual discharge to the lake blowdown r line requires opening a keylock valve in accordance with written i operating procedures, only af ter sampling.  ;

11.2.1.2 power-Generation Design Basis

' INSERT A\

The liquid radwaste systen is sized to handle expected liquid waste inputs on the basis of both volume and activity as the result of normal operation, including anticipated abnormal occurrences.

Unit 1 and Unit 2 have separate equipment and floor drain collection and process systems. This is to prevent mixing of the liquid wastes between units, if desired. The corresponding subsystems in each independent radwaste systen are provided with .

extensive crossties to provide a high degree of radwaste system availability. The laundry and sludge subsystems are conson to

• both units.

The La Salle County Station (LSCS) Units 1 and 2 liquid radwaste system is designed to permit maximum recycling of plant water, whose inventory is kept nearly constant at all times. The, plant is designed to minimize noncontaminated inputs from leakage of service water, circulating water, and groundwater Intr, the plant floor drain systen. Clean desineralized well water is used as makeup to the primary system or for decontamination verk. Since it is not feasible to elisinate or separate all noncontaminated inputs to the liquid radwaste systes, some processed liquid waste 11.2-1 REV. 0 - APRIL 1984 m -- -- v e ,----,,,,-,,,~.,,w-.,,.----w ,,m- ,,a .

SYSTEM DESCRIPTION I

The flitration and reverse a:.mosis unit is a portable, self contained, automated system designed I j to concentrate suspended and dissolved solids contained in a waste or process stream. The l system has been fabricated to meet the requirement of Regulatory Guide 1.143 and is housed on  :

seven separate skids. The skid frames are constructed of heavy-duty steel. Catch pans have been

, built into the skids to contain any leakage that may occur. Moisture sensors have been installed

in the drip pans to detect excessive leakage and shut down the system to a safe condition should

! such leakage occur.

{

The system is controlled from a remote control panal from which the operator is capable of performing all routine functions. Control of system parameters is accomplished using an industrial computer, operating in a Windows environment as the operator interfaces with a Siemensm PLC providing logic and control functions. The computer has the capability of being accessed, for data acquisition, via Modem or the site computer network. All data and control functions are protected by a multi level password system to prevent unauthorized access. Two printers are provided with the system, a report printer which will be capable of generating printouts of system operating parameters and various other reports. A line printer that will record the date, time and nature of any alarms and/or abnormal events.

The system has been designed as a tum-key unit, requiring 480 3-phase,165 Amps total power and the retaining area to store the permeate and concentrate solutions. The instrumentation necessary to monitor critical operation parameters such as pressure, flow and conductivity have been provided in analog or digital forms. The system will shutdown due to any abnormal operating parameter (high/ low flow, high/ low pressure) and has complete isolation capability.

The first system component is the Centrifugal Filter skid. The centrifugal force inside the filter forces solids to be separated from the waste stream and collect in the bottom. The solids will flush out the bottom of the filter on a timer which will open the discharge valve periodically. ,

Collected solids are flushed to the Concentrates Holding Tank.

The second system component, the filtration skid, contains an eight (8) vessel multifilament mesh bag unit capable of processing flows up to 125 gym. The filters are constructed of a polyester fiber and have the option of either~ l or 5 micron bags depending on the system '

performance. The capability to monitor the developed pressure (or solids loading) as well as sample ports to determine filter efficiency have been provided.

Effluent from tine filtration skid is fed to the third system component, the Cartridge Filter Skid.

The vessel contains 40 cantidges capable of filtrating to 0,5 micron absolute. As with the first two skids, this skid has remote backflush capability.

' j l

The fourth skid is the Charcoal Vessel. The vessel is 72" high by 42" in diameter. Itis

fabricated of fiberghss to National Sanitary Foundation Standards and to ASME Code. The l vessel has a design pressure rating of 150 psi at 100*F and a usable volume of 46 ft2 . There is

a 12 bolt flange on the top and bottom of the vessel for easy access to the retention elements and j defuser. The flanged top also aids in filling and sluicing. The flanges are sealed with O rings.

l' The fifth system component is the RO Skid. The effluent from the charcoal vessel is fed to the RO system. The RO system consists of 2 separate stages, one housing thirty six (36) elements j and the other containing fifteen (15) elements.

l The RO system is designed to optimize the concentratlon of dissolved solids, through membrane separation, into a concentrate stream and a permeate stream, which la relatively free of dissolved solids. The system is divided into two stages. The first stage concentrate containing virtually all of the dissolved solids from the feed solution, is recirculated to the concentrates holding tank, while the permeate containing a very small amount of dissolved solids, is sent as feed for the second stage.

The first stage of the RO system contains six pressure vessels each containing 6 membranes per housing. The vessels are arranged in parallel to provide a maximum permeate recovery.

The second stage of the RO system is similar to the first. This stage consists of three pressure i vessels containing five membranen. The arrangement provides for a permeate quality extremely low in dissolved solids.

The sixth system component is the Standby Polisher skid consisting of two stainless steel tanks.

Each vessel will hold 30 cu ft of resin. The effluent is returned to the Floor Drain Head Tank. l

_ The Sample Sink is seventh component in the systern. All sample ilnes are routed to tbs sink allowing either Plant Chemistry / VECTRA personnel to pull samples from any phase of the process. The sample sink contains instrumentation to continuously monitor conductivity at various points in the process. Also the sample system is continuously monitoring Silica, Turbidity, and TOC of the effluent being retumed to the plant.

VECTRA I i RVR 500 l l SYSTEM DESCRIFFION l i

. VECT'RA Technologies, Inc. (VECTRA) has developed a liquid volume reduction system designed to provide the nuclear industry with the greatest volume reduction possible of liquid  ;

! waste streams. This system, known as the RVR-500, will reduce evaporator bottoms and other  !

I non-dewaterable waste streams to a dry solid form for shipment and burial at a low level buria!

! facility. h actual volume reduction for each plant will vary according to the solida content and

radionuclides in the waste stream. The long term systems are capable of processing up to 800 l

gallons per day, while our demand use system will process up to 500 gallons per day.

l i The RVR System is a 25 cubic foot capacity dryer, using a steam heated jacket and i agitator / scraper to dry the waste. The agitator / scraper is driven by a 25 hp electric motor reduced )

to 20 rpm by a parallel gear reducer. All wetted surfaces are Type 304 Stainless Steel. A night glass is provided to observe the waste throughout the drying process.

Plant wastes are introduced through a waste supply valve. When the liquid level in the dryer reaches a predeterrnined level, (high level) the differential pressure switch will automatically shut the waste valve. The liquid is then heated and steam vapor is pulled from the dryer through the condenser heat exchanger. This condenser is cooled by a 50 ton chilled water system.- h condensate is routed to the condensate reservoir from which it can be returned to the plant and also used as the motive fluid for the system's jet pump. After approaimately three hours (time varian with each waste stream) the dryer will boil down to the low level. At this time, the waste supply valve will be opened and additional waste will enter the system, bringing the i concentration back up to the high level. (Three such transfers generate a batch cycle.)

~

The dry out phase begins with the end of the third transfer - the dryness of the material is verified by monitoring several system parameters, as well as a visual observation through the site glass.

Upon verification of dryness, the agitator helix. move,s the material to the pneumatically operated discharge valve located at the bottom center of the dryer shell. The material is discharged into the burial contairier using gravity.

The packaging enclosure, which houses the burial container, is kept under a negative pressure and vented through a HEPA system. This allows the operator to open the enclosure door to cap and remove the_ burial container without releasing contaminated particulate. The final product of some waste streams, such as evaporator bottoms, will be a dry fine powder. In such cases, a binding material can be introduced to the system prior to discharge. The material and binder are mixed for approximately 20 minutes before being discharged into the burial container. Using the binder addition will result in a free-standing billet with a compression strength of up to 250 pel.

} VECTRA is presently operating five (5) RVR-800 units at four commercial nuclear utilities in the United States and is building a trailer mounted portable unit for demand processing at I

facilities that generate small quantities of non-dewaterable waste. This unit, known as the RVR- ;

500 will be capable of processing 500 gallons of liquid waste per day. The final product of the I RVR System is acceptable for burial at both the Hanford, Washington and Barnwell South Carolina low-level disposal sites as at Type A unstable waste. Should the activity in the waste l

form require stabilization, VECTRA can provide burial containers to meet the stabilization

criteria.
