Additioanl topic for today's Teleconference Cliff:
Below is our concern with the OTI enhancement. Let me know if we can still discuss this issue on todays teleconference or if youll rather discuss this later.
LRA Section B.2.30s amendment dated June 3, 2011 states an enhancement that the scope program element is to include visual and volumetric inspections of the stainless steel makeup pump casings for cracking due to cyclic loading but it does not state what type of visual examinations will be used to detect cracking.
The GALL AMP XI.M32, One-Time Inspection states in the detection of aging effects program element that the program manages cracking due to cyclic loading using enhanced visual (EVT-1 or equivalent), surface, or volumetric examinations.
Some types of visual examination may not be sufficient to identify cracking and it is unclear what visual examinations will be performed to meet this need.
The NRC is requesting a discussion, followed by a docketed letter response later, of the type of visual examinations that will be used to identify cracking as part of the One-Time Inspection Program.
