Downcomer for 105KW and KE project CA-512-R
Sometime was available for development and improvement for future designs before K pile design was authorized. One of the objectives of this development program va was to improve upon downcomer design. It as evident that the proper approach to the problem lay not in duplication because of inadequate facilities as a means of circumventing the resultant effects of failure, but rather in the adoption of a more logical engineering approach -- analyze the cause of failure, profit from the past operating experience and concentrate upon the removal of these inherent difficulties. Accordingly, a downcomer design embodying a superior method of operation was designed and tested. The design minimizes vibration by dissipation of energy through a series of orifice screens rather than impact loading of large parcels of water and turbulent friction. It greatly simplifies the maintenance problems by designing for essentially complete replacement of the downcomer by ordinary maintenance methods. It provides for very rigid construction of the inlet section and 30 parallel flow paths in the vertical portion and thus the problem of blocking the flow has been eliminated. A detailed analysis of the points is presented in this report.

Separations P.E.S. report No. 11: Task 1, activation study, RMA Line 234-5 Building
It was the purpose of this study to determine whether it will be more desirable when activatiing Task I of the RMA. Line to revise the existing remotely operated equipment or to remove existing equipment and install a manually operated facility. It was also the purpose of this study to provide sketches and cost estimates for each alternative which could be used as a guide for preparation of a Project Proposal. At present, the process to be used in Task I has not been established. This study, therefore, necessarily covers only processes similar to those for which Task I was originally designed. Information received from the Process Unit indicates adoption of such a process is probable.
