Subsequent to that report, it was determined that six ring girder supports in Unit 2 had not been installed in accordance with their design drawings.
Reference 2 reopened the 50.55(e) report concerning the analysis of the spray piping supports based on their actual configuration. This let+c is our final report on this subj ect.

The Grinnell analysis and the plant drawings have been recon-ciled with the actual hardware and the plant is now in conformance with design requirements.
