5.0 SYSTEM DESCRIPTION The Solid Waste Management System (SWMS) collects, reduces the volume, solidifies and packages wet and dry types of radioactive waste in preparation for shipment off site to a licensed burial site. A process control flow path is presented as Figure A, and a system flow schematic diagram of the NMP2 SWMS is presented as Figure B.

AP-3.7.1 -2 August 1986

5.0 SYSTEM DESCRIPTION (Cont'd)

The Solid Waste Management System accepts dry solid trash which is, when physically possible, compacted with a trash compactor. Resin beads or powdered, resins will be dewatered in high integrity containers or will be processed along with evaporator bottoms through the extruder evaporator. When required, NMP2 will also use the services of a vendor to solidify waste.

The extruder/evaporator is a one-step volume reduction and solidification process. Two screws inside the extruder/evaporator convey the waste/asphalt mixture along its length, continually shearing and mixing the waste/asphalt. The screw speed can be regulated to control the evaporating capacity and residence time of the waste. The extruder/evaporator discharges a homogeneous mixture of asphalt and waste containing less than 1X latent water.

The solid radwaste system uses the extruder/evaporator to process waste feed from two inputs: the evaporator bottoms tank or the waste sludge tank. The waste is mixed with asphalt in the extruder. Only one waste feed path can be processed at a time.

The evaporator bottoms tank and lines are electrically heat traced to prevent crystallization of waste salts. The contents of the tank are fed to the extruder/evaporator via a transfer pump that supplies redundant metering pumps. The waste flow rate is controlled manually by adjusting the flow rates on the metering pumps The contents of the waste sludge tank are fed to the extruder/

evaporator by a system similar to, but separate from, the evaporator bottoms feed system. The waste sludge tank is supplied by waste from three sources: the radwaste filters, the floor drain filter and the spent resin tank . The waste sludge tank has the ability for decantation. A decant pump takes a suction off the sludge tank and discharges to the spent resin tank.

The contents of the asphalt tank is fed to the extruder/evaporator via redundant recirculation pumps, strainers and metering pumps.

The asphalt flow rate is automatically adjusted to yield the proper ratio of asphalt to solids. The asphalt tank and lines are contin-uously steam heated to keep the asphalt in a liquid state for ease of pumping.

As the waste/asphalt mixture moves through the extruder/evaporator, it is heated by boiler is skid steam from the electric radwaste boiler.

mounted boiler system which utilizes electricity This a

for steam production. It is a closed system, thus most of the water used for steam is returned to the boiler as condensate via the boiler feedwater system. The boiler vessel is capable of supplying 14001>/hr of steam at 233 psig and 400 P. The steam applied to the extruder is utilized in six separate heating zones for moisture evaporation. Each zone has its own temperature controller for optimum operating conditions.

AP-3.7. 1 -3 August 1986

5.0 SYSTEM DESCRIPTION (Cont'd)

Three devolatization ports along the extruder allow for water vapor to separate from the product and enter the three steam domes. A predetermined amount (4 gal.) of demineralized water is used, which ~

dissolves and boils out any salt sediment at the devolatization port. The vapors are condensed in the steam domes using turbine building closed loop cooling and drained to the distillate collection system.

The distillate collection system is a recirculating system used to continuously filter and cool the condensate from the extruder/evaporator steam domes. The condensate is recirculated from the distillate collection tank through the distillate pumps>

roughing filter and the distillate cooler, then routed back to the collection tank. The level controller maintains collection tank level and system flow.

A forced circulation ventilation system is incorporated into this system, consisting of a vent hood over the extruder/ evaporator turntable, a fan which draws air from the plant ventilation system across the extruder/evaporator turntable, and liner cool down areas.

The extruder/evaporator product empties into 50 cubic feet liners.

The liners are placed on the fill station turntable. The operator indexes (turns) the turntable, via a control switch, placing a liner under the discharge chute of the extruder/evaporator. This turntable holds three liners. When the liner level reaches a predetermined level, a high level alarm sounds to inform the operator it is time to index the container. Liners are indexed without shutting down the extruder/evaporator. Using control switches, the operator, via a pneumatic carrier, extends a drip pan under the extruder/evaporator discharge chute. The operator then indexes the turntable. Once the new liner is in place under the extruder/evaporator discharge chute, the pneumatically operated carrier is withdrawn. During this withdrawal operation, the drip pan is removed from the carrier by a stationary arm as the carrier retracts past the arm and drops the drip pan into the new liner.

Full liners are removed from the turntable to the cooldown area via a radio controlled/ operated crane. The liners remain in the cooldown area for approximately 52 hours6.018519e-4 days <br />0.0144 hours <br />8.597884e-5 weeks <br />1.9786e-5 months <br />. After the cooldown is completed the liners are capped. They are then moved by crane to the storage area using a ceiling grid coordinate system for placement of the liner.

Operation of the extruder evaporator is detailed in operating procedure 2WSS-OP-41.

6.0 SOLID WASTE SOURCES A description of each solid waste source is provided below:

Radwaste Filters these mechanical filters filter resin and crud (backwash material) from the waste collector sub-system. When a AP-3.7.1 -4 August 1986

6.0 SOLID WASTE SOURCES (Cont'd) filter reaches a pre-determined differential pressure, it backwashes the material into the backwash tank, which is then pumped to the spent resin tank.

Radwaste Demineralizers these demineralizers are used as an ionic exchange media for processing high quality water from the waste collector tanks. When determined that the resin can no longer be regenerated, the depleted resin is pumped to the spent resin tank, Condensate Demineralizer - these demineralizers remove soluble and insoluble impurities from the condensate water to maintain reactor feedwater purity. After the it is determined that these resins can no resins are pumped to the spent longer be regenerated, depleted resin tank.

Floor Drain Filter contributes to solid waste because it uses diatomaceous earth to process liquid waste of low quality. Input to the filter is from the floor drain system and the regeneration waste tank. When the filter reaches a predetermined pressure drop it backwashes to the waste sludge tank for processing through the extruder evaporator.

Spent Fuel Phase Separator these tanks receive the exhausted powdered filter (ecodex) coating from the fuel pool clean up system which is subsequently pumped to the spent resin tank.

RHCU Phase Separator these separator tanks receive exhausted ecodex or powdered resin from the reactor water clean up system which is subsequently pumped to the spent resin tank.

Contaminated Oil oil from sources within the unit that become contaminated will be stored in containers to be solidified .by a vendor with an approved procedure.

Compactible Solids compactible low level trash will be processed and compacted in a hydraulic-operated box compactor. Shoe covers, trash, contaminated paper from the chem lab, and similar materials are included in this category.

Filters and Miscellaneous Items Solid items with higher dose rates than those above will be handled on a case-by-case basis, being disposed of by methods acceptable to the burial site. They will, for example, be placed in a suitable cask prior to shipment to the burial site.

Waste Evaporator the waste evaporator processes low quality waste the floor drain collector system and, as an option, waste from 'rom the waste discharge tanks. The waste evaporator is designed to concentrate to a 25X solid concentration. The concentrates are then discharged to the evaporator bottoms tank for processing through the extruder evaporator.

AP-3.7.1 -5 August 1986

6.0 SOLID WASTE SOURCES (Cont'd)

Regenerant Evaporator the regenerant waste evaporator receives regeneration solutions from the condensate,demineralizer system and radwaste demineralizer resin regeneration system as well as the.

radwaste regeneration sump. The regenerative waste evaporator is designed to concentrate to a 25K by weight solid concentration of sodium sulfate. The concentrates are then discharged to the evaporator bottoms tank to be processed thru the extruder evaporator.

Spent Resin Storage Tank exhausted resin from the condensate demineralizer, the radwaste demineralizer, RWCU phase separator, the spent fuel pool phase separator and the radwaste filter backwash tanks are sluiced to the spent resin storage tank. The waste from the spent resin tank is pumped to the waste sludge tank for processing thorough the extruder evaporator.

7.0 PREREQUISITES 7.1 Adhere to Station Radiation Protection Procedures 7.2 Assure proper asphalt input per ASTM-D-312-71 and N2-CSP-14.

7.3 Assure that NMPC Safety Procedures are adhered to.

7.4 Assure adequate recirculation of waste to be solidified (per 2WSS-OP41-Asphalt Operating Procedure).

7.5 Assure proper ventilation (radwaste ventilation).

8.0 PROCESS CONTROL SYSTEM COMPONENTS 8.1 Asphalt Volume Reduction System Variables Influencing End Product Pro erties This section identifies and defines the process variables of the WPC-VRS System. These process variables have a direct bearing on the properties of the final waste product and relate only to the ability to form a free standing monolith with essentially no free-standing water. Additional process variables, such as pH, must be controlled to minimize corrosion within the system.

However, because these variables do not affect the ability of the waste product to form a monolithic solid upon cooling, they will not be discussed below.

The following variables influence the properties and consistency of the final solid product:

A. Asphalt type; AP-3.7.1 -6 August 1986

As halt Volume Reduction S stem (Cont'd)

B. Waste chemical species being incorporated into the asphalt matrix, water content; C. Ratio of waste-to-asphalt; and D. Process temperature.

A detailed discussion of the effect and limitations placed on each of the foregoing items follows:

As halt T e NMP2 will use an oxidized petroleum-based asphalt, conforming to ASTM-D-312-71, Type III requirements. This grade of asphalt has a low residual volatile content, and a high molecular weight. At room temperature, and at all normal ambient conditions, this material is a freestanding monolith. Unit 2 will specify Witco Pioneer 221, or an equivalent. This is one of the means by which process control for asphalt quality is achieved. Werner &

Pfleiderer Corporation will be consulted if use of an alternate asphalt material is planned. A chemical analysis will be performed on each batch of asphalt received at the site. Verification of the asphalt type will be done per N2-CSP-14; Waste Chemical S ecies Testing will be done to determine the oil content and physical properties of the waste to be solidified per N2-CSP-14. The type and relative quantity (waste-to-asphalt ratio) of waste chemicals being incorporated in the asphalt matrix has a direct influence on the properties of the final product. Encapsulation of inorganic salts and solids typically "stiffen" and harden the waste product; whereas organic liquids have the opposite effect. When the proper ratio of waste-to-asphalt is maintained, final product properties relative to solidification, for all practical purposes, are independent of the waste type.

Werner 6 Pfleiderer Corporation places a limit of 1.0% oil and organic contaminants in the waste feed stream for process controI, and Unit 2 adheres to these guidelines.

Waste-to-As halt Ratio in the Product The ratio of waste-to-asphalt contained in the end product has the most bearing on the viscosity and physical consistency of the product during processing. The recommended weight ratios of waste-to-asphalt for each waste feed is as follows:

AP-3.7.1 -7 August 1986

Waste-to-As halt Ratio in the Product (Cont'd)

Ratio of Waste-to-Asphalt Feed in the End Product

1. Evaporator Concentrates 40/60 to 50/50*

• 2. Spent Resins 45/55 to 50/50*

3. Filter Sludge 40/60 to 50/50*

• Optimum value depends on type and quantity of contaminants present.

Should the ratio of waste-to-asphalt be increased above the range specified in the foregoing table, the end product viscosity will increase and may exhibit a grainy texture. This could lead to "pyramiding" of the product in the container, thereby decreasing the container filling efficiency. In all cases, the product will cool to form a freestanding monolith. If lower than specified waste loadings are realized, the end properties will approach that of pure asphalt.

Proper waste-to-asphalt ratios in the product are automatically maintained by a coordinated proportioning feed system to the extruder/evaporator. Operator involvement is limited to setting the initial proportion of waste-to-asphalt flow. To'o this, the chemistry department will determine, by sampling, the solids content of the waste feed. After the sample analysis, the chemistry department will determine the proper feed control settings. See N2-CSP-14 for flow rate calculations. The operator must visually confirm that the proper ratios are being maintained.

A CCTV camera can be used to "view" the discharge from the extruder/evaporator, and the TV monitor located in the control room allows the operator to observe the physical consistency of the product as it is discharged into the container. Flow rates will be calculated based on the information supplied in Topical Report No.

HPC-VRS.001, Rev. 1, May 1978 Appendix B Solid Contents.

Process Tem erature A proper temperature profile along the length of the extruder/evaporator is required to provide adequate evaporative (process) capacity, and to ensure that free water is not discharged from the machine. The process temperature profiles for all typical Nine Mile Point waste types are as follows:

Waste Type Process Temperature* ( F)

Zones: 1 2 3 4 5/6 7 Evaporator Concentrates 165 265 300 330 375 350 Spent Resins, Filter 165 265 285 300 285 230 Sludge

• Temperatures are approximate.

AP-3.7.1 -8 August 1986

Process Temperature Low temperature alarms are provided to alert the operator to a low temperature off~ormal,condition which could potentially lead to the discharge of .free water. These alarms are based on a percent (X) deviation from set point, typically + 10 F. The percent deviation permitted can be adjusted in the field up to + or 25%%d

(+ or 75 F) of the instruments range.

If off~ormal conditions persist for two minutes, the extruder/evaporator is automatically tripped to prevent free water from being discharged into the container. Free water cannot be discharged in the interim, because the residual heat of the extruder/evaporator itself is sufficient to effect evaporation.

The foregoing controls/interlocks are provided to prevent the discharge of, free water to the container. The temperature profiles specified above have been proven by experiment to'ield residual total moisture content in the product of 1X by weight for waste concentrates (inorganic salts) and 10% by weight for bead resins.

This margin provides assurance that free water cannot be discharged under normal circumstances. Under upset or off~ormal conditions, discharge of free water is prevented by the low temperature process interlocks.

Temperature profiles will be logged every two hours of equipment operating run time. See Figure "D".

Minimum Functional Com onents In support of maintaining the four major process parameters; Process Temperature Asphalt, Type Mixture Ratio Oil Content and, to assure a stable waste form consistent with the guidance of the PCP, operators will ensure that the following list of equipment is available, as a minimum, prior beginning to processing:

closed circuit television system at the asphalt loading stations; all temperature profile monitoring instrumentation with calibration; the asphalt and waste metering equipment are operational; and all radwaste sampling stations.

Wastes will not be processed through the extruder/evaporator, when any of the above equipment is inoperative.

AP-3.7.1 -9 August 1986

8.2 Hi h Inte rit Containers NMP2 will also use a high integrity container (HIC) for dewatering to satisfy the stability requirements. Each HIC used will have a certificate of com liance available and dewatering procedures based on an NRC a roved vendor rocess control ro ram or "Topical Report will be a part of N2-WHP-4 Cask Loading procedures.

Documentation of adherence to these procedures shall be kept as records.

8.3 Oil Solidification Contaminated oils will be stored in containers at designated areas within the plant. A vendor with an approved process control program that is acceptable at the burial sites will be used to solidify the oil. An operating procedure for the portable oil solidification system will be established as N2-WHP-10A. A sample production level process control program will be established as N2-WHP-10B.

8.4 Tem orar Radwaste Processin (Contracted Vendor)

In the event NMP2 requires the services of a contracted vendor to temporarily process and package radwaste on site, NMPC will obtain the services of an NRC approved vendor demonstrating their commitment to 10CFR61 stability requirements. The vendor must demonstrate that the have completed Class B and C testin or provide a schedule of com letion. Vendor must have an ap roved procedure to rocess Class "A waste.

After fuel load an engineering review, per 10 CFR50.59 of the subject topical report procedure or program will be performed to assure that vendor operational requirements are compatible with NMPC system and licensing commitments.

All vendor procedures will be reviewed and approved as required by Site Administrative Controls. The operating procedure for the vendor solidification will be approved. A production sample level process control procedure shall be implemented. The vendor shall be provided samples per 2WSSWP-41 and N2-CSP-14.

8.5 DRY ACTIVE WASTE (DAW)

NMPNS Procedure No. N2-WHP-12, "Solid Dry Waste Collection and Compaction", describes the proper and safe steps required to collect and prepare low specific activity DAW for offsite shipment. Procedure No. N2-WHP-11, "Process Control DAW", assures the process control of Dry Waste Collection and Compaction by identifying those items which most directly influence the quality of the end product. All dry active waste is examined before AP-3.7.1 -10 August 1986

8.5 DRY ACTIVE WASTE (DAW) (Cont'd) compaction, and any liquids or items found that would compromise the integrity of the package or violate the burial site license and/or criteria are removed and separated as specified in this procedure. Dry active waste is shipped in containers that meet'the transport requirements of 49CFR173.425. At times, radiation .limits preclude disposing of DAW in LSA boxes or drums, and this waste is disposed of in liners per Procedure No. N2-WHP-4.

9.0 SAMPLING All the various sources of. wastes are directed to one of two final tanks. These tanks are the evaporator bottoms tank (Tk10) and'he waste sludge tank (Tk8). When ready to process waste from one or the other of the above sources, the tank's contents are 'isolated from further input, recirculated and Tk8 agitated to ensure a homogeneous mixture. Once these tanks are isolated, no further waste is added and a batch number will be assigned per the operator work sheet. Figure "C" Before processing, a sample of each batch is obtained from the tank in accordance with Operating Procedures N2-IOP-41 Asphalt Solidification Operating Procedure and N2-CSP-14 Solid Radwaste Surveillance. The s'amples are analyzed and the sample data form in N2-CSP-14 is completed. Chemistry personnel will determine the chemical and radionuclide content of each sample in accordance with the procedures as listed. After the sample is analyzed, the operator will complete the "Operator Work Sheet" per instructions and complete the "Temp Profile Log" (Figure "D") during processing. After collecting the feed rate data from the chemistry department, the operator will sel'ect the given feed rates for introduction into the extruder/evaporator.

Should circumstances result in interruption of a batch, the source tank will be isolated and remain so until processing can resume.

10.0 WASTE CLASSIFICATION The minimum waste characteristic requirements identified in 10CFR61.56(a) shall be satisfied via implementation of Procedure S-RP-6.

The NMP2 PCP assures that wastes determined acceptable for near surface disposal are properly classified for the purpose of segregation at the disposal site. Waste classification is performed consistent with the guidance provided in the Branch Technical position pertaining to Waste Classification and is based upon the concentration of certain radionuclides in the waste form as given in 10CFR parts 61.55 and 61.56.

AP-3-7.1 -11 August 1986

WASTE CLASSIFICATION (Cont'd)

The methods utilized by NMP2, and the frequency for determining the radionuclide concentration of the final waste form is conducted in accordance with NMP2 Procedure For Solid Radwaste Sampling,

~

N2-CSP-14. Classification will be. performed in accordance with S-RP-6, Packaging and Transportation of Radioactive Material.

Chemistry and Rad Protection assume these responsibilities.

ADMINISTRATIVE CONTROLS This section of the NMPC PCP describes administrative controls as they relate to quality assurance, training, documentation, and record keeping programs implemented by the PCP.

Administrative controls are utilized to ensu're that all processing is performed in accordance with the guidelines set forth in the PCP. Management-controls are established for the safe operation of NMP 2.

Qualit Assurance Implementation of the Operational QA program is assured by ongoing review, monitoring and audit functions in accordance with the Applicable NMPC Quality Assurance Department Procedures.

The administrative controls designed to prevent solidified waste forms from being released for shipment prior to test sample verification of acceptability require QA to verify that a sample record sheet has been properly executed for each waste batch prior to processing.

The Manager Nuclear QA, operations has the authority to stop work when significant conditions adverse to quality require action.

The Nuclear QA program assures compliance with the waste classification and characterization requirements of 10CFR61.55 and 10CFR61.56.

With respect to waste characterization, the requirements of 10CFR 61.56 are intended to provide stability of the waste. Stability is intended to ensure that waste does not structurally degrade and affect overall stability of the waste disposal site. The auditing function of the Nuclear QA program assures that stability requirements are achieved in accordance with 10CFR61.

In the event a vendor is contracted to perform temporary radwaste services, the Nuclear QA program requires management review of the ven'dor procedure. The purpose of this review is to assure that vendor operation and requirements are compatible with responsibilities and operation of NMP2.

AP-3.7.1 -12 August 1986

11.2 ~1rainfn A 'raining program is being implemented for personnel having responsibilities related to waste processing operations. The results of this, training program shall ensure that waste processing is performed within the specific requirements of the PCP. To

'accomplish this objective and to provide the necessary control of the solid waste processing the following training programs will be implemented.

11.2.1 Radwaste 0 erations Unit 2 Plant Trainin Pro ram A. These programs are designed to provide competent, trained personnel. During classroom instruction, each operator must qualify by completion of the described course with an average grade of 80 or above. On-the-job training, in conjunction with classroom instructions, will ensure that each radwaste operator maintains an acceptable level of skill and familiarity associated with radwaste controls and operational procedures.

Due to the involvement of radwaste operators in the start-up of NMP2 radwaste systems, the experience gained will suffice for the on-the-job training requirement. The training procedures are detailed in the Nuclear Department Training Manual.

(N2-NTP-13)

This training includes familiarity with the following radwaste components or related systems.

LIQUID Drains, collection tanks with sub systems, waste and regeneration evaporators, seal water SOLID - Extruder-evaporator and associated support systems LWS Computer operation and interfaces Waste handling procedures for packaging and shipping of radioactive material Condensate demineralizer system Spent fuel and phase separators subsystem Steam supplies 11.2.1.1 Chemistry and Radio Chemistry Technicians will be trained per S-NTP-1 (Training and Retraining of Chemistry Radio Chemistry/Technician).

11.2.2 Trainin Schedule The formal classroom Radwaste training program is scheduled for approximately twelve weeks. Depending on the needs of the plant staffing, this program could cover a continuous twelve week cycle or become part of the NMP2 normal rotating shift schedule which would cover one full year.

11.2.3 Personnel Retrainin Personnel will be retrained on an annual basis to identify individual needs for retraining. Personnel demonstrating a significant deficiency in a given area of knowledge and proficiency may be placed into a remedial training program. This program is specifically structured to upgrade knowledge and skills identified as deficiencies. Successful completion of the accelerated training program is evaluated by a written and/or oral examination.

The Requalification Training Program will cover fundamental review of system modifications, revisions of procedures, and changes or experiences in the nuclear industry.

11.2.4 Training Records The training records shall be maintained for audi.t and inspection purposes. These records are considered permanent records and shall meet the applicable requirements of "Requirements for Quality Assurance Records for Nuclear Power Plants" and AP 9.0 (Administration of Training).'1.3 Documentation Control and Record Retention QA program audits of waste classification records are performed on a periodic basis. Management evaluation of such audits shall be performed and as such satisfy the requirements of 10CPR20.311 (d)(3).
