WP5 SITUATION • The content of WP5 • LOT1: Development of bentonitebuffer and pelletinstallation. • LOT2: Quality of installation • LOT3: Problemhandlingtools Haapala Keijo
WP5 SITUATION • Two machines has developed • Installationmachine (BIM) for bufferblockemplacement • Buffertransferdevice (BTD) for transferring of bufferblocksfromservicetunnel for BIM. Haapala Keijo 3
BIM 5
BUFFER INSTALLATION SEQUENCE 3. Crane over dep. hole 2. Block taken from container 1. Positioning 4. Block and pellet installation 5. Transfer device positioning 6. Empty gripper to the shelf 7. Shelf forwards and crane over container 8. Block taken from container Haapala Keijo
LOT1, Installation of bentonite buffer and pellets • BIM wasready for shipmentfrom the manufacturer in Octoberlastautum. • Testplan of DemonstrationPhase 1 hasprepared. • Writing of Operating and Service Manual for machines. • Testhall in Onkalo areawasready in the end of March. • Finalprogramming and preparations of the machinefor the teststartedin Aprill. Haapala Keijo
LOT1, Installation of bentonite buffer and pellet • Things to note: • Laser trackerchanged, Leica -> API Control -> someextrawork. • Automation and electrichascausedextrawork • Co-operationbetweendifferentcomponents • Wiringfaults -> brokencomponents. Haapala Keijo
LOT1, Installation of bentonite buffer and pellet • Things to note: • Worksafety is a bitharderthanexpected • Limited access to testhall, onlypersonswhohave a task in the project. Haapala Keijo
LOT2: Quality of installation • Workhasdoneat the sametimewith LOT1, mainlyprogramming • Main part of the workwilltakeplacewhen the bufferinstallationdemonstrationsstart. Haapala Keijo
LOT3: Problem handling tools. • What is neededif the bentoniteblockfalls to the deposition holeduringinstallation? • Demonstrationsafter LOT 1 and 2. • Workhasdivided in twosituations: • Beforecanisterinstallation. • Aftercanisterinstallation. Haapala Keijo
DEMONSTRATIONS • Demo Phase 1: Testing in testhall in Onkalo site. • Demo Phase 2: Testing in Onkalo demonstrationtunnelwithconcreteblocks. • Demo Phase 3: Testing in Onkalo demonstrationtunnelwithbentoniteblocks. Haapala Keijo
DEMO PHASE 1 IN TEST HALL • Purpose to finalize the installationmachine. • Detailedtest for differentfunctions • Adjusting the speed of functions in the machine • Perform the installationtestwithfullsizeconcreteblocks • To find out what is critical Haapala Keijo
DEMO PHASE 1 IN TEST HALL • Mostimportantpart of demonstration • Estimatedtestingtime 3 months: April - June, ifeverythinggoeswell. Haapala Keijo
TEST HALL Haapala Keijo
BIM IN TEST HALL Haapala Keijo
BIM IN TEST HALL Haapala Keijo
CONCRETE BLOCKS WITH CONTAINER TOPS Haapala Keijo
DISPOSAL HOLE IN TEST HALL Haapala Keijo
DEMO PHASE 2: TESTING IN ONKALO WITH CONCRETE BLOCKS • Targets: • To test the installation in Onkalo conditions • Installing of wholebufferwithintwohours Haapala Keijo
DEMO PHASE 3: TESTING IN ONKALO WITH BENTONITE BLOCKS • What kind of effect the bentonite gives to installation process? • What is the effect of moist conditions in Onkalo • How safe is the process? Haapala Keijo
DEMO PHASE 3: TESTING IN ONKALO WITH BENTONITE BLOCKS • Possibly isostatically pressed bentonite blocks are not available. • Alternative buffer: Mixture of uniaxially pressed benonite and concrete blocks. • The handling of concrete blocks with vacuum lifter is more risky than bentonite blocks Haapala Keijo
DEMO PHASE 3: TESTING IN ONKALO WITH BENTONITE BLOCKS • Alternativebuffer: Mixture of uniaxiallypressedbenonite and concreteblocks. • Bentoniteblocks in criticalpositions: • Bottom and top • First and lastring • First on the canister Haapala Keijo
WORK SAFETY OF BIM AND BTD • During the demonstrations, access to the testplace is limited. • Demo Phase 1 in the test hall. • Whendemonstration is going on, onlyoperators and reponsiblepersonscanbe in the testhall! • Specialarrangements for visitors; the access is denied, followup of demonstrations via cameras. Haapala Keijo
WORK SAFETY OF BIM AND BTD • Demo Phase 2 and 3 • Steering of installationwillbeperformedbycameraswithwirelessmethod outside of disposaltunnel • During the installation the access to disposaltunnel is denied Haapala Keijo
WORK SAFETY OF BIM AND BTD • Before the start of demonstrations, is needed: • Detailedtestplan. • Safetyestimation of tests. • Training of employers for working in Onkalo area and in demonstrations. • Operatingmanual of machines. Haapala Keijo
