DOCUMENT REV. SHEET SD-OP-003 D 3 CNSQ 1602/8-78

THE CEMENT PROCESS MAKES USE OF THE READILY AVAILABLE PORTLAND I CEMENT AND HYDRATED LIME (CA(OH)2) TO SOLIDIFY LIQUID WASTES*

THE PROCESS IS INITIATED BY TRANSFERRING LIQUID WASTE INTO THE CNSI DISPOSABLE LINER* THE WASTE IS THEN CONDITIONED BY DE WATERING OR ADDING CONDITIONING CHEMICALS AS REQUIRED* (CON DITIONING CHEMICALS MAY ALSO BE PRELOADED INTO THE LINER)* WITH CONTINUOUS AGITATION PROVIDED BY THE INSTALLED MIXER BLADES, CEMENT IS ADDED TO DEVELOP A THICK PASTE LIKE SLURRY WHICH WILL SOLIDIFY TO A HARD, WATER-FREE END PRODUCT*

3.2 PROCESS PARAMETERS CEMENT UNDERGOES FOUR SEPARATE REACTIONS DURING ITS CURING TIME WHICH PERMANENTLY COMBINES CEMENT, WATER AND A VARIETY OF IONS FOUND IN WASTE STREAMS TO FORM A STABLE, SOLID CONCRETE END PRO DUCT* CERTAIN CHEMICALS AND METALLIC IONS PRESENT IN THE WASTE ACT AS ACCELERATORS OR RETARDANTS TO THESE REACTIONS. BY PRE TREATING THE WASTE WITH CHEMICALS DESIGNED TO LIMIT OR NEUTRALIZE THESE EFFECTS, A CONTROLLED, ACCEPTABLE CURE TIME CAN BE ACHIEVED AND THE WASTE-TO-ADDITIVE RATIO WILL BE SIGNIFICANTLY IMPROVED*

EACH OF THE REACTIONS IS EXOTHERMIC AND BY CONTROLLING THE SPEED OF REACTION AND MINIMIZING THE TOTAL CEMENT ADDITION BY THE USE OF CERTAIN ADDITIVES, THE HEAT DEVELOPED BY LARGE VOLUME SOLIDI FICATIONS WILL ALSO BE MINIMIZED*

THE SAMPLE VERIFICATION PROCEDURE WILL SERVE TO VERIFY THE EXACT PRETREATMENT REQUIRED TO ACHIEVE THE OPTIMUM WASTE-TO-ADDITIVE RATIO* SOLIDIFICATION RATIOS HAVE BEEN DEVELOPED THROUGH A CNSI RESEARCH AND DEVELOPMENT PROGRAM* HOWEVER, WASTE MAKE-UP AND DENSITY VARIES WIDELY FROM ONE WASTE STREAM TO ANOTHER MAKING THIS VERIFICATION A NECESSARY QUALITY ASSURANCE STEP IN THE EN TIRE SOLIDIFICATION PROGRAM. THE AMOUNT OF ADDITIVES AND CEMENT TO BE USED FOR SAMPLE AND FULL SCALE SOLIDIFICATIONS ARE PROVIDED BY FIGURES 2 THROUGH 5,AS APPROPRIATE.

3.3 MOBILE UNIT DESCRIPTION 3.3.1 THE CNSI CEMENT SOLIDIFICATION UNIT IS A PORTABLE SYSTEM CONTAINING ALL PIPING, SUPPORT, CONTROL AND MONITORING EQUIPMENT NECESSARY TO SOLIDIFY RADIOACTIVE LIQUID WASTE USING THE CEMENT PROCESS*

3.3.2 THE UNIT IS COMPOSED OF SEVERAL PROCESSING SUBSYSTEMS, EACH CONTROLLING A SPECIFIC FUNCTION OF THE CEMENT PRO CESS. THESE SUBSYSTEMS INCLUDE WASTE TRANSFER, CHEMICAL ADDITION, CEMENT CONVEYOR, VENT, AND DEWATER SYSTEMS*

CONTROL FUNCTIONS FOR THE UNIT ARE INCORPORATED INTO THE PNEUMATIC AND MAIN CONTROL PANELS* SERVICE SUPPLIES ARE PROVIDED BY THE UTILITY AND DISTRIBUTED THROUGH THE SERVICE AIR, WATER, AND ELECTRICAL DISTRIBUTION SYSTEMS.

DOCUMENT REV. SHEET SD-OP-003-NP D 4 CNSO 1 O/S-78

3*3.3 MOST OF THE MOBILE UNIT COMPONENTS ARE ARRANGED ON POR TABLE FRAMEWORKS (SKIDS) TO PROVIDE FLEXIBILITY OF OP ERATIONS FOR EITHER INDOOR OR OUTDOOR USE. THE CEMENT CONVEYOR, CONTROL PANEL, PUMP SKID, HYDRAULIC SKID AND FILLHEAD CONTAIN MOST OF THE MAJOR ELEMENTS OF THE MOBILE UNIT*

3.3.4 A CLOSED-CIRCUIT TELEVISION SYSTEM IS AN INTEGRAL PART OF THE MOBILE UNIT AND ALLOWS THE OPERATOR TO MONITOR THE SOLIDIFICATION PROCESS.

3.4 SYSTEM OPERATION 3.4.1 BEFORE BEGINNING ANY WASTE PROCESSING WITH THE CEMENT SOLIDIFICATION UNIT, THE CNSI OPERATOR SHALL COMPLETE A SUCCESSFUL SAMPLE VERIFICATION IN ACCORDANCE WITH THE SAMPLE VERIFICATION PROCEDURE OF SECTION 5.0.

3.4.2 THE SUCCESSFUL SAMPLE SOLIDIFICATION PARAMETERS ARE RECORDED ON A SOLIDIFICATION WORKSHEET (FIGURE 1)*

THESE PARAMETERS ARE AMPLIFIED FOR FULL SCALE SOLIDIFI CATION VALUES TAKEN FROM FIGURES 2 THROUGH 5, AS APPROPRIATE*

3.4.3 ACTUAL FULL SCALE SOLIDIFICATION SHALL THEN BE CONDUCTED IN ACCORDANCE WITH THE MSU OPERATING PROCEDURE (REF.

2.4) USING THE PARAMETERS CALCULATED ON THE BATCH SOLIDIFICATION FORM ON THE BOTTOM OF FIGURE 1.

4 SEQUENCE OF OPERATION THE CONDITIONING CHEMICALS MAY BE PRELOADED INTO THE LINER OR ADDED TO THE WASTE WHILE MIXING. THE ADDITION OF CHEMICALS OR WASTE MAY BE INTERRUPTED AT ANY TIME.

THE MIXER MAY ALSO BE SECURED DURING WASTE OR CHEMICAL ADDITION WITH NO EFFECT ON THE PROCESS, HOWEVER, IT MUST REMAIN IN OPERATION DURING THE CEMENT ADDITION. AFTER CEMENT ADDITION, THE MIXER IS SECURED AND THE PROCESS IS COMPLETE*.

3.4.5 MIXER SPEED THE MIXER SPEED SHOULD BE HIGH ENOUGH TO ALLOW COMPLETE MIXING OF WASTE CONDITIONER AND CEMENT. GENERALLY, THE SPEED WILL BE SET AT 40 RPM WHILE ADDING CONDITIONING CHEMICALS AND 40 To 75 RPM WHEN STARTING CEMENT ADDI TION. THE SPEED WILL BE INCREASED TO 100 RPM AFTER TWO THIRDS OF THE CEMENT HAS BEEN ADDED*

3.4.6 WASTE-TO-CEMENT RATIO (BY VOLUME)

THE NORMAL WASTE-TOCEMENT/CONDITIONER RATIO (BY VOLUME)

WILL BE APPROXIMATELY 2 TO 1 FOR BORIC WASTE AND ABOVE 2.5 TO 1 FOR RESINS, POWDEX AND OTHER SOLIDS

,DOCUMENT REV. SHEET SD-OP-003- D 5.
