Item 1 Determine whether SA-312 or A-312, Type 300 Series fusion welded pipe is in use or planned for use in safety-related systems subject to design stresses greater than 85 percent of the Code allowable,stresses.
For the purpose of this check the actual wall thickness of the piping products will be considered adequate if the code requirements for pressure design of the piping products are satisfied using 85 percent of the maximum allowable stress at the design temperature.
Response to Item 1 The Palisades Plant does not have any SA-312 or A-312, Type 300 Series fusion welded pipe in safety-related systems.
Item 2 For those piping components using greater than 85 percent of the allowable stresses identify the application of the piping including the system, pipe location, pipe size, pipe configuration (elbow, tee), design pressure/
temperature requirements and the manufacturer.
