[ ais-h-ley.- -Weido-ng Q u--e-stio-n for -06GS -AMPaudit.wpd A W Q f I Page 1 These are additional AMP questions/issues. When entered into the Q&A database the next available number should be used.

1. B.1.21 Aboveground Outdoor Tanks.

In Element 5. Monitoring and Trending, GALL states "The effects of corrosion of the aboveground external surface are detectable by visual techniques. Based on operating experience, plant system walkdowns during each outage provide for timely detection of aging effects. The effects of corrosion of the underground external surface are detectable by thickness measurement of the tank bottom and are monitored and trended if significant material loss is detected."

Question: What is the schedule of plant system walkdowns by OCGS and is the OCGS schedule consistent with the GALL recommendation?

2. B.1.15 Boraflex Rack Management Program In the Program Description, GALL states "... (2) Completing sampling and analysis for silica levels in the spent fuel pool water and trending the results by using the EPRI RACKLIFE predictive code or its equivalent on a monthly, quarterly, or annual basis (depending on Boraflex panel condtion)..2' However, the Applicant stated in it's Program description that "Sampling of silica in the spent fuel pool is on a weekly basis and its trending using RACKLIFE is on a frequency of two years or less."

Question/Issue: The frequency of trending using RACKLIFE by applicant is less frequent than the GALL recommendation. If RACKLIFE trending is not done on at least an annual basis, this should be identified as an exception to GALL and the basis provided.
