Subject:

Radiant Energy Shield SAMA It turns out that your suggestion about the radiant energy shield for the DS cable was a good one.

We have done a quick evaluation and found that the avoided risk benefit for such a mod would be $152,371, based on a CDF reduction from 7.04 E-06/yr to zero. We believe that adding radiant energy shielding for potentially affected portions of the conduit could be accomplished for less than $50,000, specifics not yet determined.

We are continuing to take a last look for any additional fire SAMAs. We havent found anything yet, but will inform you of the results.
