ANO Dry Cask Storage Schedule Ross Scarano, R-IV, DNMS l

I talked with Jim Melfi and Marissa Bailey on AN0's schedule.
Thomas Andrews, R-IV, DRS SFP0 sent 4 additional questions to ANO last Thursday. ANO will be responding to them this week.
In addition, AN0 has issued a condition report concerning a color change to the Zinc coating recently obse.ved.
The canister (MSB) that has been used for the practice runs has been exposed to pool water several times. Apparently the Zinc coating is showing a yellow tint. Marissa said that ANO will need to respond to the issue of what caused the change in color and what does this mean. We would expect the ANO response to be includ?d in their response to the 4 questions issued last week.
I have a memo from Marissa with 19 changes to the ANO procedures that were committed to in the ANO response to the bulletin and CAL that need to be reviewed by me to ensure that the changes have been incorporated into the procedures.
I will be doing that this week.
After the ANO responses to the 4 questions and the yellow tint problem have been found to be acceptable, and after I confirm that the procedures are complete, SFP0 will draft two letters to ANO. One to close the response to the bulletin and one for Callan's signature to lift the CAL. As soon as these are issued, ANO plans to start fuel movement.
The ANO outage starts Sept 16.
It takes approximately I week to complete the loading and movement of a cask.
Thi: includes about 3 days of prep work, which ANO was planning to do on the first cask last week.
They want to load at least 2 casks before the outage. With the preloading activities completed for the first cask, it is possible that two casks could be loaded in 11/2 weeks.
Basically, however, they are running out of time to start the process and still have enough time to complete activities without rushing.
The outage is scheduled for 28 days.
If fuel movement doesn't start in Sept., we d.ould expect a mid Oct. fuel movement schedule.
There is a 50-50 chance that everything can get done this week and the letters issued by Friday so that ANO can start fuel movement over the holiday weekend.
Tom Andrews and I are prepared to travel to ANO on short notice, should that be necessary.
Jim Melfi, Tom, and I will establish 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> coverage during the loading of the first cask.

COMPLIANCE BULLETIN FOR POINT BEACH EVENT Part 72 is VERY MUCH a performance-based rule.
The adequacy and appropriateness of dry storage cask coatings is a compliance issue:
Part 72.236(h), "The cask must be compatible with wet or dry spent fuel loading and unloading facilities."
Part 72.146(b), states that "The licensee shall establish design control measures to items such as the following... compatibility of materials.."
Part 72.234 re cask design states that casks must be designed in i
accordance with Subpart G (which encompasses 72.146 (b)).
The coating issues extends, for dual transport / storage casks, to Part 71.
Part 71 is a prescriptive rule.
Part 71.43(d), "A package must be made of materials and construction i
that assure ti.at there will be no significant chemical, galvanic, or other reaction among the packaging components, among package contents, or between the packaging components and the package contents, including possible reaction resulting from in leakage of water, to the maximum credible extent. Account must be taken of the behavior of materials under irradiation."
