Section 5 reactor incident file general information from 1945
C Reactor was shutdown over a 20 minute period at 2058 hours on 10-27-67. The reactor was shutdown because of an excessive Panellit pressure increase on tube 2562. Subsequent examinations revealed that a fuel element rupture had occurred in process tube 2562, and the element was stuck within the process tube. The maximum force required to remove the rupture was 28,000 pounds, thus exceeding the force limit of 12,000 pounds specified by Process Standards. Then applying the higher-than-normal forces for stuck charge or tube removal, it is necessary to consult Process Guide HW-56000 on ``Stuck Charge and Tube Removal Forces -- C Reactor.`` Subsequent to the stuck slug and tube removal it is then important to evaluate the adequacy of the Process Guide. The purpose of this report is to present some of the data, action taken, and development concerning this particular fuel failure.
