The first HI-TRAN 300 transporter has been successfully manufactured and factory tested by Holtec International's Advanced Manufacturing Division in Camden, New Jersey. With a rated lift capacity of 300 tons, the transporter is intended for moving used fuel casks as well as heavy loads at Holtec's SMR-160 plant.An artist's rendering of the HI-TRAN 300 (Image: Holtec)
The transporter is a vertical heavy load hauler designed by Holtec's Nuclear Power Division (NPD) to serve as the single-failure-proof workhorse for hauling loaded Holtec dry used fuel storage system components and for executing inter-cask canister transfers. The HI-TRAN 300 is also envisioned to transport heavy loads at Holtec's SMR-160 plant currently undergoing regulatory review in Canada and the HI-STORE Consolidated Interim Storage Facility being developed by Holtec in New Mexico.
Holtec said it developed HI-TRAN "to solve the transporter reliability problems procured from third parties that occasionally have plagued some dry store campaigns in the industry". It noted that HI-TRAN is built as a "safety-significant machine and has certain unique reliability features that differentiate it from other machines sold in the industry".
HI-TRAN 300 - weighing 121 tonnes - moves on two parallel caterpillars to minimise ground pressure and has zero turn radius. It features four hydraulic lifters and has a rated lift capacity of 300 tonnes, which is sufficient to haul the heaviest loaded cask supplied by Holtec.
Holtec said the successful development and deployment of HI-TRAN 300 completes its programme of redesign of key ancillary devices to improve their operational reliability. The transporter, it said, also eliminates reliance on subcontractors during cask loading campaigns.
