Response

Response to to Request Request for for Addit AdditionalI Information Informat quested below, As requested below, thethe NRC NRC requested requested GGNSGGNS to to provide provide detailed detailed and and specific specific information information to support the to support the bases bases forfor limited examination in limited examination in all all requests requests for for relief and, therefore, relief and, demonstrate impracticality.

therefore, demonstrate impracticality . TheThe questions questions for for each relief request each relief request areare as as follows:

follows:

nclude descriptions a) Include descriptions (written (written and/or sketches, as and/or sketches, necessary) of as necessary) of the the interferences interferences to to applied n applied nondestructive mination (NDE) examination to (NDE) techniques.

describe NDE b) As applicable, describe NDE equipment {ultrasonic scanning equipment (ultrasonic apparatus) and scanning apparatus) and details details ofof the the listed listed bstru obstructions (size, shape, proximity imity to to the the weld, etc.) to weld, etc.) to demonstrate li accessibility limitations, demonstrate accessibility and discuss whether whether alternative alternative methods methods or advanced technologies could d be be employed employed to maximize ASM to maximize ASM E E Code Code coverage.

c) Fu ly clarify c) Fully clarify the the wave modality an wave modality ification a and insonification angles used for all ultrasonic examinations.

d) d) Show cross-sectional coverage plots to describ describe ASME Code volumes examined.

ee) If surface examination ination isis required required by by the ASME Code the ASME Code in in addition to the add.ition to volumetric examination, the volumetric examination, statestate surface examinations whether surface examinations were were performed performed on on any any ofof the subj the subject components and examination coverage that that was obtain was obtained.

f) If not of included, state whether included, state whether any any indications indications were discovered as were discovered as aa result result of of Co Code-required examinations, and and howhow these these indications indications have have been been disposition dispositioned.

The questionss apply apply toto the the relief relief requests listed below.
