A different kind of warning system will sound Tuesday at the Sequoyah Nuclear Plant and Watts Bar Nuclear Plant.

TVA will be testing a new supplemental voice emergency notification system, which is battery powered and capable of operating for up to seven days.

The alarms will can be mounted on metal poles and withstand high winds.

Officials say the need for the system was apparent after Japan's Fukushimaevent. TheJapanese facility lost all AC electric power for extended periods, and with itthey lost their public address system, radios and cell phones. The result was abreakdown of plant-wide communications that endangered the safety of personnel.

Tests will occurTuesday around Watts Bar Nuclear Plant from 8-10 a.m. EDT, and aroundSequoyah Nuclear Plant from 1 to 3 p.m. EDT.

Tuesday's test will be done with speakers mounted on trucks. If its successful, the alarms will then be added as a permanent fixture at the plant in early 2014.
