10 CFR 50.54(q) states that the licensee shall follow and maintain in effect
emergency plans which meet the standards in
10 CFR 50.47(b) and the requirements in appendix E of this part. The
TMI Emergency Plan indicates that the plant paging system provides immediate warning and instructions to onsite personnel in an event of an emergency. In March 2010, Exelon began testing their on-site speakers in response to an IR and industry operating experience. A total of 301 out of 405 on site speakers were tested. Of the 301 tested, 108 speakers had identified deficiencies. Contrary to the
TMI Emergency plan, the 108 speakers would not provide immediate warning and instruction to onsite personnel during an emergency. This issue was identified in Exelon\'s
CAP as IRs 922582 and 1035621. Upon discovery, Exelon issued a standing order to issue blow horns to Operations and Security staff to notify people in areas that would need to be evacuated during an emergency. The finding is of very low safety significance because prompt compensatory measures were taken upon discovery.
