to type 316 stainless steel. These replacement spool pieces have not
been received at the site.
Modifications in the suppression pool in accordance with the latest design have not commenced. The inspector was informed that construction drawings on site and that material procurement had been initiated.
Fire Seals Mechanical - The inspector reviewed the radiation test report for Dow Corning's Sylgand 170 silicone.elastemer used in the Tech-Sil lead radia-tion seals in mechanical penetrations.
