Reference 7 stated that the required analysis, to confirm that the i

l reactor building sprey piping supports (anchors) are within the ASIE Section III Code alloweble stresses, was completed except for six anchors la each talt. Per these anchors, the octani tias history water hammer loedlag curves have been applied to more closely provide the actum1 Icedings that would be experienced by the anchers. IIT Grianell ladicated that the results of this effort have shown these anchors to be withia Code requirenests. sowever, the fissi ITT Grinnell reports have yet to be processed throush the mechtel Engineering review cycla.
