.5.2.2 Control of Process Parameters (continued) 9.Tem erature a Concentrate waste temperature of 120'F to 160'F is recom-mended and is monitored with a thermocouple.
In the event of waste temperature exceeding 160'F the solidification process is stopped until temperature is adjusted.'The recommended temperature forother.waste is 40'F to 130'F.Due to the indoor location of the waste streams, these-limits are not expected to be exceeded.10.'ater to Cement Ratio f The recommended range for water to,cement ratio is 0.4 to 1.0 and varies with waste stream.-This ratio is controlled by solidification formulas inclu'ded in the operating proce-dure.5..2.3~Pre-Solidification Sam lin and Testin Pro ram l.~Sam lia a A sample of the waste requiring solidification must be taken'n.order to determine any pretreatment of waste needed prior to solidification, determine-waste-characteristics,,perform test solidification and determinewa'ste classification of the waste to be solidi.fied.If the radioactivity."levels are too high t'o permit full size.samples-to be~taken, then smaller samples shall be taken with the results corrected accordingly.
Normal sample.points are given in Table 6.3, however," any sample point.which provides a representative sample may.be used to obtain a sample.2.Chemical Anal sis of Waste Sam les Evaporator bottoms, filter sludges, and chemical waste shall be analyzed for percent solids concentrations, pH, boric acid concentration, and oil content and the results recorded on the Waste Solidification Worksheet.

5.2.3 Pre-,Solidification Sam lin and Testin Pro ram (continued) 3..Radiochemical Anal sis of Waste Sam les 4 A gamma isotopic analysis shall be performed on each batch of waste to be solidified.
This analysis is used to deter-,.mine the proper waste classification in accordance with 10CFR61 Waste Classification System..The results of the gamma isotopic analysis'shall be attached to-the Waste Solidification Worksheet.
4~Test Solidification As.required by Technical Specification Surveillance requirements 4.11.3 a test solidification of at least every tenth batch of each type of wet radioactive waste shall be performed.
Whenever pretreatment of a batch is necessary the waste sample shall hive the required pretreatment accomplished prior to the test solidification.
The appro-priate proportional amount of Portland cement and sodium metasilicate, as applicable, required by the Solidification Formula shall be used.Where practical, all chemicals used , to condition or solidify waste or simulated waste in the solidification test shall be"identified to actual chemicals which are used in the full scale solidification.
The-chemical analysis required by this section, the amounts of cement, sodium metasilicate, and waste, and the percent of free liq'uid shall be recorded on the Test Solidification Worksheet.
A copy of this worksheet shall be present with the Solidification System operator prior to performing'aste solidification operation.
If any'est solidification fai1s to verify solidification, solidification of the batch under test shall not be per-formed until such time as additional"test samples can be obtained, alternative solidification parameters can be determined and a subsequent test verifies solidification.
If the initial test sample from a batch.of waste fails'to verify solidification, then representative test samples shall be collected from each consecutive batch of the same type of waste until three consecutive test=specimens demon-strate solidification with le'ss thin or equal'to 0.5X'free'iquid.4 For high activity waste, where handling samples could result in personnel radiation exposures which are incon-sistent with ALARA principles, representative non-radioactive samples may be test solidified.
These samples shall be.as close to the actual waste and chemical., properties as possible.For resins, the resi'n beads shall be depleted prior to test solidification.
, PLP-300, Rev.0 Page 11 of 21' 1 I'.2.3 Pre-Solidification Sam lin and Testin Pro ram (continued)
Test solidification shall be done in accordance with Plant Procedure CRC-858 Test Solidification of waste.5.Test Solidification Acce tabilit The test solidification will be considered acceptable if the test solidification, produces a free standing mass with the free liquid less than or equal to 0.5X by volume..If either or both of the above checks fail to meet thestated criteria, alternative solidification parameters must be'determined before solidification can proceed.5.3 Pol er'Solidification 5.3.1 Solidification Formulas The-solidification of volume reduction system dry product is achieved by the use of a three component polymeric system developed by DOW~Chemical Company.It consists of a polymer binder, which is a modified vinyl ester resin, a promoter and a catalyst.Dry products are solidified by mixing with the polymer to acheive a homogeneous mixture.Solidification formula,.for dry product waste is given in the Polymer Solidification System Operating Procedure, OP-120.05.04.
The formula includes the required amount of binder, catalyst, promoter, and dry product.These values shall be recorded on the Solidification Worksheet.
The formula is pre-tested in a solidification laboratory in order to verify the solidification results in a free-standing mass.New solidification formulas may be developed and added to operating procedures.
New formulas will be pre-tested to verify that solidi-fication results*in a free standing mass.New formulas or changes in formulation shall be reviewed by Operations Radwaste Engineering and approved by the Operations Manager.5.3.2 Control of Process Parameters 1.Pol er Stora e Tem erature and A e;Temperature and'ge can affect the polymer by causing.premature initiation of the polymerization reaction, although at a slow rate.Over time this may result in thickening of the polymer which may cause the amount of polymer added to the drum to be incorrect.
Dow Binder has a recommended storage life of 6 to 12 months.To maximize PLP-300, Rev.0 Page 12 of 21 Y'"
5.3.2 Control of Process Parameters (continued) this life the polymer is recirculated and air-sparged.
Polymer temperature is automatically controlled by recir-"culating the polymer through a chiller package heat exchanger when temperature reaches 65'F.The promoter and catalyst have a storage life in excess of one year.Manufacturers'emperature, storage and shelf life recom-mendations shall be observed or chemical integrity shall be verified by a lab scale solidification test without waste.V 2.Com onent Pro ortions, ,.The solidification agent is a multicomponent polymer system consisting of a polymer binder, a promoter and a catalyst.Careful control of each of these components is required for proper solidification.
The promoter controls how soon the solidification begins.If too much promoter is used, then the reaction begins before addition of the dry product is complete, whereas too little results in excessive curing times.The catalyst controls the rate of reaction.Too much catalyst results in excessively high rates which in turii leads to a build up of internal stress and ultimate m'echanical failure of the solidified product.Conversely, too little catalyst again results in excessive curing times.The quantity of polymer binder and promoter.is controlled by flow instrumentation.
The catalyst comes in'premeasured packets and is inserted by the operator.The amounts of polymer binder, promoter, and catalyst shall be recorded on the Solidification Worksheet.
3.Maxi.n The polymer solidification syst'm is designed with an in drum mixer that effectively coats the dry product with polymer and is a single-use item.The mixer is.placed in the drum by the operator at the Polymer Filling Station.The polymer-promoter combination, the in-drum mixer, and the catalyst'ontainer should be placed in'the drum in the appropriate sequence as described in the Polymer Solidi-fication System Operating Procedure.
To maintain proper mixing speed, a speed indicator, system interlock and alarms are provided;Tem erature of Dr Product The curing of the polymer is an'xo thermi c reac t ion.The react ion rat e is increased by , heat and thus is self-accelerating
.It is important to note that any source~of heat accelerates the reactant.Therefore , the incoming dry product must be maintained below a maximum temperature PLP-300, Rev.0 Page 13 of 2 1 4 5.3.2 Control of Process Parameters (continued)
I of 130'F.'his condition is monitored by the system and must be satisfied.
for the drumming process to commence.Temperature of dry product shall be recorded on the Solidi-fication Worksheet.
Dr Product Particle Size Distribution I'ecause mixing the dry product with polymer is actually a.coating operation, the total surface area to be covered is a process parameter.
The surface area to'be covered is a function of particle diameter which is controlled by the process parameters in the Fluid Bed Dryer.Bedtemperature, feed pH and atomization air is carefully monitored and controlled to produce an acceptable product.These.system parameters are monitored and.controlled in accordance with the Volume Redu'ction System Operating Procedure, OP-120.05.02.
\I 6.Dr Product Feed Rate Since the first step in the solidification sequence is , actually a coating step, the rate at which the dry product is introduced into the drum containing the polymer must be controlled.
The feed rate is automatically controlled by.the Polymer Solidification System.V 7.'roduct-to-Pol er,.Ratio, The polymer.solidification system controls the ratio of dry'roduct to polymer at, approximately 2.5:1'y weight.Although it is possible-to exceed this ratio,'esting has shown that long term performance is reduced.Resistance'to leachability is a major long term performance goal of the solidified waste material.As the Product-to-Polymer ratio increases, the resistance to leachability is reduced;The ratio given above is a reasonable compromise between achieving adequate resistance to leaching and obtaining drum loadings that result in solidification economy for the particle size distribution.
1 ll 8.Contaminants Carbon in some forms interferes with polymer solidification process.Activated charcoal can be solidified'in concen-trations up to 2 percent by weight, however carbon will not be processed through the Volume Reduction System or,solidified by the Polymer Solidification System.PLP-300;Rev.0 Page 14of 21 5.3.2 Control of Process Parameters (continued)
\9.'xothermic Period Because of the chemistry involved in the polymerization
, process, it is possible to follow the course of the'reaction by monitoring temperature as a function of time., During dry product addition there is only a moderate increase in the temperature of the-bulk material inside the drum.Because'the chemi'cal reac'tion is exothermic,.
the.temperature of the mixture in the drum increases., This reaction is self-accelerating until polymerization is complete.A rapid temperature increase is readily detectable and is a definite indication that polymerization is proceeding normally.This period of temperature rise is referred to as the exothermic period.and starts about 45 minutes after the catalyst release and lasts about 20 minutes.The beginning of this exothermic period has been defined to be the point at which the rate of temperature increase is equal to 1'F per minute.It should be noted that, given the chemistry of the reaction, there is virtually no other cause for such a rapid temperature increase except for polymerization.
Verification of the onset of the exotherm periods(1'F/mi.n,temperature increase)shall be logged on the Sol'idification Worksheet.
5.3.3 Pre-Solidification Sam lin and Testin.Pro ram~Sam lin Direct sampling of Volume Reduction Dry Product is not feasible due to-the nature of the product.Samples of liquid inputs.to the Vo'lume Reduction System will be taken and'calculational methods will be used to determine concen-trations of radionuclides in the dry product.2~Chemical Anal sis of Waste Sam les Evaporator bottoms, chemical waste and decontamination
'olutions shall be analyzed for pH and adjusted between 10 and ll in the solidification pre-treatment tank as necessary.
3~Radiochemical Anal sis of Waste'Sam les A gamma isotopic analysis shall be'performed on each batch of Volume Reduction feed.Calculational methods will be used to determine concentrations of radionuclides in the dry product and to determine proper waste classification.
in accordance with-lOCFR61 Waste Classification System.The results'of the gamma isotopic analysis and calculational results shall be attached to the Waste Solidification Worksheet.
PLP-300, Rev.0 Page 15 of 21 5.3.3 Pre-Solidification Sam lin and Testin Pro ram (continued)'
4.Test SoLidification Since the Volume Reduction System Dry Product is not a wet waste no pre-solidification tests are required by Technical Specification Surveillance requirement 4;11.3.Test solidification without waste shall be performed to verify chemical integrity if manufactuiers'emperature, storage o'r shelf life recommendations are not met.5.4 10CFR61 Im lementation Solidified radioactive waste generated at Shearon Harris Nuclear Power Plant shall meet the requirements of Title 10 Code of Federal Regulations Part 61.5.4.1" Waste Classification 10CFR61.55 For wet waste streams, waste classification shall be based upon isotopic analysis and the use of scaling factors for hard to measure isotopes.For dry product isotopic anaLysis of feed streams to the Volume Reduction'System, scaling factors for hard to measure isotopes,'and calculational methods shall be used to determine con-centrations of radionuclides in the dry product and provide the appropriate waste classification'., Initially generic scaling factors will be used for waste classifi-cation.Each waste stream shall be sampled after the first three months of commercial operation and on an annual basis thereafter.
These samples are analyzed by a commercial Laboratory to confirm the continued validity of the scaling factors.Calculational methods will be updated, as required, based on the results of these samples.A computerized waste classification and'hipping program, WASTETRAK, is normally used to determine waste classification from isotopic analysis and scaling factors.Manual methods may be used if the computer system is not available..
Waste Classification is controlled by plant procedure HPP-115, Classification of Radioactive Waste for Shipment.5.4.2 Waste Characteristics.LOCFR61.56 Waste Characterization requirements'is demonstrated.by a combination
,.of the methodology stated in this'rocess Control Program, Plant Procedures, and Waste Form Stability Testing Programs performed.by Stock Equipment Company and Dow Chemical Company.PLP-300, Rev.0 Page 16 of 21 5.4.2 Waste Characteristics-10CFR61.56 (continued)
Minimum Characterization Re uirements Waste at Shearon Harris Nuclear Power Plant.is normally packaged in 55 gallon drums.In no case shall, waste be packaged in cardboard or fiberboard boxes.Liquid waste streams're solidified by the solidifica'tion system or by a solidification vendor in accordance with a qualified Process Control Program.For dry active waste absorbent,.material is added to absorb any unintentional liquids.The pre-solidification testing program and use of the process control'program provides reasonable assurance that liquids do not exceed 1/of the volume.For any package containing water and/or organic substances in concentrations exceeding'Type A quantity that could radiolytically generate combustible gases, a determination by calculations, test, or measurements shall be performed to ensure that hydrogen generated is limited to a molar quantity that would be no more than 5%by volume or, the-equivalent limits for other inflammable gases, of the secondary container gas void at STP over, a period of time that is twice the expected shipment time.or the cask cavity will be inerted.For any package containing materials with radioactivity concentrations'ot exceeding'Type A quantity this determination is not required;Experience has demonstrated utility waste streams do not contain or generate toxic gases, vapors'or fumes and do not contain hazardous, biological, pathogenic or infectious materials.
2~Waste Stabilit Waste stability testing.results for the Stock Cement Solidification System are contained in Stock Equipment Company Topical Report,"Waste Solidification Process For Low-Level Radioactive Waste.": The data presented in the report demonstrates that generic waste streams and s'imilar waste streams'of lower concentrations, solidified using'he Stock Waste Solidification Process, produce products which'omply with existing stability regulations.
Waste stability testing results for the Dow Waste ,Solidification-Process are contained in the.Topical Report,"The Dow Waste Solidification Process For Low Level Radioactive Waste Generic Waste Form Certification Results." The data presented,'in this report demonstrates that Volume reduction dry product solidified with the Dow Waste Solidification Process produces products which comply with existing stability regulations.
/PLP-300, Rev.0 Page 17 of 21 5,.4.2 Waste Characteristics 10CFR61.56 (continued)
Control parameters and limits established by these topical reports are, controlled by the PCP and the solidification formulas used in the system operating procedures.
Plant procedures ensure<<that all reasonable efforts are made to eliminate unnecessary voi'd spaces within the waste packages.'owever, to ensure production of a stable waste form, void spaces are left within each contai'ner.
Such void spaces are necessary to allow for proper mixing of the solidification medium.Therefore, processing does not eliminate void.spaces to the extent that the ability to produce a stable waste form is compromised.
5.4.3~Labels Each package of waste shall be, clearly labeled to'dentify waste classification in accordance with the appropriate shipping procedures in Table 6.1.5.5'10CFR20.311.Im lementation
