PURPQSE The purpose of thts Process control Program <PCP> ts to Insure that the Radwaste Syste* ts used as applfcable to process all low level rad,oact1ve wet wastes so11d1f1ed or dewatered at Quad-Ctt,es Nuclear Power Station.
The Process Control Program shall contain the current formulas. sa~p11ng, analyses. test. and deter*,nat1ons to be made to ensure that process1ng and packag1ng of solid rad1oactlve waste based on demonstrated processtng of actual or simulated wet so11d wastes will be accomp11shed 1n such a way as to assure COllpltance wtth 10 CFR Parts 20~

Net wastes at Quad-C1t,es Statton consist of f11ter ined1a Cpowdered res1n and f1ber>, bead res1n, sump sludges. tank residues, and higher activity cartridge f11ters.
Hhen expended. these wastes are transferred to vartous storage tanks or storage conta1ners and 1n some cases these wastes are transferred directly 1nto a burtal container for process*ng. Vendor processing of the waste ts normally done w1th the waste contatner 1n etther a transportat1on cask or a process sh1eld wh1ch offers the advantage of reduced rad,atfon exposure to personnel tnvolved tn perfor~1ng the necessary package handling operations.
In some cases where rad1at1on eKposure wou1d be m,n1mal. processing of the waste is done with the contatner placed on an unshtelded flatbed trailer.

<In-plant cement solid waste system 1s 1,mtted to use for Clas1 A unstable waste forms only>
The restn s1urry ts transferred to one of two centrtfoges for dewater1ng.
The centrifuges have a capacity of ZS gpm.
The so11ds are separated from the water and drop 'nto a hopper associated w1th each centrifuge.
The water ts routed back to a storage tank.
Each hopper has a 40 cubic fex>t capacity. At the bottom of the hopper there 1s a hopper dtscharge valve. This ts a remotely operated, a1r operated, fatl closed valve. Connected to the hopper d1scharge valve 1s the sludge chute and the drum feed valve. The sludge chute ts 8 Inches '" d1ameter and 6 feet 5 1nches long, w1th a capac1ty of 2.2 cub'c feet. The drum feed valve 1s also remotely operated. atr operated. and fatl-closed. The hopper dtscharge valve and the dru* feed valve are 1nterlocked to prevent both valves frOtl betng open stmultaneOllsly.
Ce111ent ts addelt*to**a**drllll frc1r*the cement stlo. "The ce111nt stlo has a capac1ty of 620 cubic feet.* Cement 1s fed through a rotary feeder do~n a transfer tube through the mf xer head. tnto the drum.
The mixer goes,nto the drum and forms a seal to prevent d1spers1on of cement dust or sptllage dur,ng *1~1ng. The mtKer has two speeds, 100 rpm and 200 rpm, that are programmed 1nto the MtK cycle.
Drums are capped at the load-out conveyor area before loadf ng tnto a sh1pp1ng vehicle. A cap 1s set 1n place and a seal rtng ts snapped over it. A threa~ed bolt 1s used to tighten the seal r1ng.
Drum storage consists of three conveyor ltnes, wtth roe11 for 25 drums on each 11ne.
Drums stored on the storage 1tnes are re11e>ved and e1ther sh1pped, stored tn storage b1ns located 1n the radwaste fact11ty, or stored tn the Inter1* Radwaste Storage factl,ty.

- 4 Qperat1on of the In-PJaot Cement Sgltd Haste Sxit1111 In order to Insure solld1f1cation of spent res1ns ~tth no free water. tests were conducted at Quad-Ctt1es Station us1ng unspent res,n. Fresh res1ns were m1xed up tn the proport1ons that would be expected to be normal1y processed. These restns were then put tnto a drum and the drum was processed through the cemen.t system.
The dru11 was capped as normal and allowed to set 1n storage for 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
After 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. the drum was cut Qpen lengthwise and 1nspected.
The results of the 1nspect1on resulted 1n a change of the proportions cf water and cement unttl the final product was solfd and free of water. A serfes of drums were processed us1ng spent res,ns, and the drums were vtsually tnspected for no free water prtor to shtpptng.
No free water was observed. Based on these tests, spec1f'c station procedures were wr1tten to assure that soltdtfted barrels produced by the 1n~plant cement system fall w1thln the test results. S1nce all of the barrels made on the In-plant system are c1ass1fted as Class A unstable, per 10 CFR 61, no addttlonal testtng outside of the tntttal station tests ara required.
The general procedure that ls followed. to process spent restns ts descrtbed below.
Spec1f1c plant opera.t1ng procedures are fol lowed by the opera tor.

The restn ts transferred frOll the hopper to the drum through the sludge chute.
The d1scharge valve on the sludge chute 1s a manually operated re1110te valve.
The operator vtews the drum through a *trror and f111s the drum to between*
the f1rst and second roll hoop fr011 the top of the druM.
Although this method or adding res1n to the drum ts not prectse, 1t can be controlled to a h'gh degree. If an operator determtnes that the quanttty of res1ns var1es from the prescribed level, he can compensate wtth water and/or cement.
- 7.
Hater 1s added <remote operation>. Normally 16-20 gallons of water are added to each drum.
This amount can be varied tf necessary for complete soltd'f,catton. The amount of water raqu1red,s selected, and a flow Integrator g1ves the tnlet valve a closed stgnal when that amount ts deltvered.

The mtxer lowers tnto the drum and forms a tight seal.
The mfxer will begin to rotate at slow speed.
The air s11de blower and dust collector are started. The cement feeder and v1brators start and cement ts metered to the drum.
The m1xer 1ncreases to fast speed.
The cement feeder stops and the air sl,de blower and dust collector stop.
Hhen the mtxer completes the cycle, the RPM meter w111 start to decrease. At th's point. the mlKer control sw1tch ts 110ved from AUTO to FAST and the *txer ts 9tven an additional 5 mtnutes on fast speed.
The switch 1s then returned to AUTO, and the m1xer cycle ts complete.

After the tank Is filled with radwaste. a decant pomp ts used to remove water from the top of the settled sludge.
Hhen the decant1ng operation 1s completed, the tank contains about 1,900 gallons of sludge.
