  • Standard Notes (A-E) indicate useful comparison to GALL
  • LRA Tables 3.X.1 Summarize AMRs with Standard Notes (A-E)
  • Plant specific notes used to clarify AMR logic
  • Standard Notes not provided for TLAAs N Progress Energy 49 Standard Note Definitions A. Consistent with NUREG-1 801 item for component, material, environment, and aging effect. AMP is consistent with NUREG-18 df AMP.

B. Consistent with NUREG-1801 item for component, material, environment and agin effect. AMP takes some exceptions to NU REG-1 801 AMP.

C. Component is different, but consistent with NUREG-1801 item for material, environment, and aging effect.

AMP is consistent with NUREG-1 801 AMP.

D. Component is different, but consistent with NUREG-1801 item for material, environment and aging effect.

AMP takes some exceptions to NUNEG-1 U1 AMP.

E.

Consistent with NUREG-1801 for material, environment, and aging effect, but a different aging management program is credited.

Standard Note Definitions - Continued F. Material not in NUREG-1801 for this component.

G. Environment not in NUREG-1 801 for this component and material.

H. Aging effect not in NUREG-1 801 for this component, material and environment combination.

I. Aging effect in NUREG-1 801 for this component, material and environment combination is not applicable.

GALL Consistency - Observations

  • Objective: Identify degree of GALL alignment to facilitate LRA review
  • Consistency evaluation with 2001 GALL -

useful but subjective

  • Generic disposition of Table 3.X.2 AERMs listed as "None" may expedite review - Tend to be note "J" N Progress Energy 53 Questions?
