This procedureshall be scheduledas required.

Equipmentlocation' lOS-KWbasin sandfilterbackwashpit (SFBWP)

Introduction:;,

The purposeof this procedureis to gathervisualand depth informationand monitorunderwateractivitiesin the lOS-KW SFBWP and transferchannel. Profilelighting(the use of lightingand shadowsto show the surfacecontour)will be used to assessthe contourof the sludge surface. Selectmeasurementswill also be taken todeterminethe actualsludgedepth.

The person-in-charge(PIC)will determineif additionalmeasurementsare necessary.

The control/videostationwill be setup outsidethe radiationarea or in lowestpossibleexposurearea to reducepersonnelexposure(ALARA).

This procedureis to providea mechanismto assist in fully characterizingthevolume and surfacetopologyof the sludgecurrentlydepositedin the sandfilterbackwashpit (SFBWP). SurveillanceSystemsEngineering(SSE)personnelwill gathervisual informationutilizinga closedcircuittelevision(CCTV)color camera,mounted to stainlesssteel extensionpoles. Connectionsallow the camerato beconnected'with a pan and tilt to allowbetterpositioningcapabilitiesand to get

i good landscapeprofilingof the sedimentsurface. The informationwill bevideotapedto a one-halfinch NTSC or Y/C format. Underwater'lightingwill beaccomplishedby means of 500 watt underwaterlamps.

Duringthe performanceof this proceduredifferentlocations,angles,depths_andlightingschemeswill be utilized,as directedby the field lead, to providemaximuminformation•The grid patternshown in the procedurewill be utilizedas much aspractical.

Depth measurementswill be accomplishedusingthe camerain conjunctionwith a30 inch scale attachedto stainlesssteel extensionpoles by metal clamps. Thestainlesssteel poles are screwed-insectionsconnectedto providethe requiredtotal length. They are hollowwith a solidmetal core at the screw fittingtopreventradiation"shine"up the shaft. Theyare markedto show one inch incrementsand are standardequipmentfor this type of work, The steelscale is approximatelyone inch by one-halfinch and is equippedwith a knifeedge to allow for easy

0 intrusioninto the sludge. The scale is incrementedto one-quarterof an inch. The. underwatervideo camerawill be used to place and monitorthe scale. One-halfinch° resolutionis the goal of the depth measurements. The purposeof the scale is to

minimizethe intrusionintothe sedimentwhile maximizingthe accuracyof the depthmeasurement,

Although the scale can be placedonly in locationswhere a straightshot existsfromthe water surfaceto the sedimentlayer, some abilityexiststo reach and seebeneathpit obstructionswith the camera• This abilitycombinedwith depthmeasurementdata should allow a full characterizationof sludge volume.

The currentoperatorshave a lot of experiencewith sedimentobservationon theHanfordsite and will exercisecautionduringmeasurementsto minimizesedimentdisturbance. If clarityproblemsdevelop,time will be taken to allow the sedimentto settle out as determinedby the field lead.

A referencepoint will be establishedat or above the surfaceof the pit to aid inthe mappingeffort. This will enable the performersof the procedureto establishwhetheror not there is unevennessin the floorof the pit or if they are gettingfull penetrationof the sedimentlayer in all areasof the pit. A stringor wiremay be extendedfrom the referencepoint selectedto allow easiermeasurements.

At this time it is plannedthat multiplemeasurementswill be taken at selectedaccessiblelocations. Data will be recordedon all measurementsindependentof thevideo record which will also documentall measurementactivities. Includedwith thedepth measurementdata will be data to tie the measurementto a known physicalreferencepoint out of tilepit. SSE personnelwill also be verifyingthat as-builtSFBWP dimensionsmatch those shownon referencedrawings•

Safetyharnessesor other fall protectionwill be requiredfor all personneltakingmeasurementdata. Any scaffoldingused will have handrails. A pre-jobbriefingwill addressfall hazardsand protection. Personnelaccessinto the pit, other thanby handrailedscaffoldingwill be prohibited•

A radiationwork permit (RWP)has been writtenfor this activity. A pre-jobbriefingis requiredby the RWP.
