   Support DOE Idaho Cleanup Project at Idaho National Lab.*Peach Bottom Canister Retrieval Equipment. The equipment must be remotely operated due to radiological hazard. The 18-4.5” diameter by about 13ft long canisters containing spent fuel are inserted in 18 tube ports in a 25.56” OD basket that is stored in an underground steel vault of 30” ID. There is a center tube port where a lifting rod can be threaded to top insert for lifting of whole basket. There are two types of canisters, one is regular bearing on a bottom strap welded on top of a 5” long spacer tube welded to bottom of tube port and another one is salvage bearing on bottom strap welded on bottom of tube port. There is a pintle on top of canister that was designed for lifting of canister. Some of pintles, welds on straps and spacer tube have corrosion, which may breach if lifted on pintle or basket. Mr. Chen modified one and created a new proposal.*IWTU, mechanical engineer for Carbon Reduction Reformer (CRR) Vessel Fluidizing Gas Distributor (FGD) removal/installation tool design. The tool is a structural system supported on two forks of a forklift to remove or install the FGD in the CRR or as a standalone support on floor for the FGD maintenance and repair. The tool consists of a structural tube framing system with 2 vertical jacks and 2 horizontal jacks to support a rotating shaft driven by a gearbox. Those fine adjustment mechanisms are needed to connect the tool to the FGD with bolts and rotate the FGD. The manually operated lubricated mechanisms include self-locking keyed screw jacks, spherical bearings, sliding channels, plain bearing shaft with collars and pad-lock gearbox system. The critical design is a so-called gearbox locking system because the shaft with the keys is locked in the bore of the gearbox that must move with the shaft during vertical and horizontal adjustments but must be restraint from rotating when the handwheel cranks the gearbox to drive the shaft to rotate.
