The Electron-Ion Collider (EIC) project will require the construction of three satellite cryogenics plants to cool cryomodules. Two critical components of the IR10 plant are the distribution system and the recooler. The distribution system will connect the cryogenics infrastructure, the cryomodules, and the recooler. During this project, a flexibility analysis of piping in the recooler and the distribution system was performed to find and correct the effects of cooling the piping from ambient temperature to 4 K. Both components were modeled and analyzed in AutoPIPE. The third distribution system iteration with 15 added bellows was the most optimal. Additionally, a preliminary spacer design was analyzed in Ansys, and the stresses were larger than the allowable values. These results may influence the spacer design and the placement of bellows in the IR10 distribution system. It is now possible to estimate the number of bellows required for similar plants like IR2 and IR6.
