Licensee Action on Previously Identified Items (0 pen) Unresolved Item (462/79-06-06):
Records not on site to enable verification of piping that had been through a hot bending process met the quality requirements of the ASME Code subarticle NB-4223.2.
The licensee stated that the quality measurements would be taken at the e.Arliest possible convenience.
(Closed) Unresolved Item (461/79-06-07):
Heat treatment furnace strip charts not available on site for review. The inspector reviewed 26 strip charts.
Several of these were held at the required temperature for less than one hour.
Ilowever, the licensee stated that all of the reactor re-circulating loop piping was internally clad or replaced with 316 SS and re-solution annealed. Design specification 21A2005AV Revision 3 used for the rework and replacement pipe is more stringent as to heat treatment requirements.
