Susquehanna Steam Electric Station Siren Measurements - 07/09/07

BRRC wins contract to verify proper function of the Susquehanna Steam Electric Station emergency outdoor warning system.

Description

In July of 2007, Pennsylvania Power and Light (PPL) contracted with Blue Ridge Research and Consulting, LLC (BRRC) to conduct acoustical tests on the new siren system for the Susquehanna Steam Electric Station. The siren system around the Susquehanna Steam Electric Station consists of 76 rotating sirens. These sirens were built by ATI and are of the type R-HPSS16. The testing consisted of taking sound level measurements of eight individual sirens using the ANSI S12.14 methods.

Methodology

The acoustical data obtained with these measurements is used by PPL as part of their verification of the new siren system design and operation. The ANSI S12.14 testing procedure calls for the maximum and the average noise levels to be reported from each test. Each siren was tested with a bucket truck and an array of 5 microphones placed 5 feet apart vertically. Additional microphones were used during the test to ensure that the siren levels did not exceed the ANSI requirements.
