The . audit resulted in five findings and one observation as:

summarized below:  ;

Finding 01 -One penetration seal configuration test ' report contained anomalies for . which adequate ;

justification. was ~ not documented. Additional ,

concerns were noted' with three of the inspected penetration seal '

Finding 02 ' An installed 3-hour rated fire wrap ~ was observed to be inadequately installed and in a degraded- '

conditio Finding 03 Several instances 'of degraded fire protection - ,

ecuipment, and ineffective measures were icentified during a plant walkdow '
