LOFT Feed and Steam Lines Isolation Snubbers Support Structure. Supplement A

摘要

The support structure for the LOFT feed and steam lines isolation snubbers has been reanalyzed. The original analysis used loads from piping analyses of the feed line and steam line. These loads have changed due to redesign and reanalysis of these lines. This report revision compares old and new loads and applies the new where necessary. Comparison showed that the loads applied in the original analysis were greater than present LOCE loads and present LOCA + SSE loads are greater than the loads applied in the original report. Analysis was in accordance with the 1970 Edition of the AISC Manual of Steel Construction and all stresses were found to be within the allowable range. 5 refs. (ERA citation 10:039229)
