Following completion of the installation of the parallel microwave circuit, station personnel were informed and a poll was conducted at approximately 1633 hours on April 14, 2008, to verify no loss of capability of the ANS. This poll was unsuccessful. Immediate corrective actions included removal of the parallel microwave circuit and performance of an additional siren poll. The subsequent siren poll was completed successfully at approximately 1739 hours on April 14, 2008. A silent testing performed at 1000 hours on April 15, 2008, confirmed that all sirens are operational. An investigation has been initiated to evaluate the exact nature of the intended change, and to examine the processes used to control activities that may impact ANS operation. The ANS may not have been available on April 14, 2008, from approximately 1200 hours when the parallel circuit was installed, until the configuration was restored and successfully polled at 1739 hours.</br>The licensee has notified the NRC Resident Inspector.
