Federal regulators are calling the Monday night Indian Point siren test a success after 97 percent of the newly installed sirens worked properly."Of the 167, we had five that came up with amplifier issues," says Entergy spokesperson Robyn Bently. "We will be sending work crews out today to make sure those issues are fixed."While siren tests are usually done in the morning, they were done Monday evening so people who are not normally in the area during the day could become familiar with the sound.The new sirens replaced the old system which suffered numerous failures over the past few years. Entergy has been fined hundreds of thousands of dollars for missing three deadlines in getting the new system operational. The company plans to add even more sirens to the site. The work is scheduled to be completed by mid-August.
