While performing an IC-month inspection of penetration fire barriers (Trojan MP-12-13) it was discovered that some of the penetrations were either marginal, questionable, or not functional as 3-hour barriers. Upon receiving this information we followed the action statement as required.

This special report is being written to the commission pursuant to specifi-cation 6.9.2 outlining:
1.
