May 2009 Project:

Transfer Cask Cup Design for the Spent Fuel Pool
Transfer Cask

Design and analyze a Transfer Cask (TC) Restraint Cup for safe fuel transfer operations. The TC Restraint Cup will hold the TC in its desired position during fuel loading and prevent impact of the TC with any adjacent fuel racks during a seismic event.


Our engineering team produced a detailed, 3-D, finite element model in conjunction with simplified models of the TC. Several loading scenarios were considered and all applicable loading conditions (design, accident, etc) were considered. Furthermore, a design and analysis package satisfying all design requirements was created.

HEA has completed numerous jobs similar to the one shown above (Similar Projects)
