Based on the information provided, PGKE's use of Code Case N-416-1, with your proposed additional surface examination and exception to VT-2 examination requirements, is authorized pursuant to 10 CFR 50.55a(a)(3)(ii).
Use of Code Case N-416-'1 is authorized until such time as this Code case is published in a future revision of Regulatory Guide

At that time if you intend to continue to implement this Code case, you are to do so by incorporating any limitations issued in Regulatory Guide 1.147.
The granted exception to Code Case N-416-1 rem'ains effective through the second inservice inspection (ISI) program plan after which time your entire VT-2 examination program should conform to the applicable Code edition for the Diablo Canyon Nuclear Power Plant third ISI interval.
The staff's evaluation and conclusions are contained in the enclosed safety evaluation.
