Siren Problems at Three Mile Island
2001-2013
 
• October 5-9, 2001: “Licensee sirens in Lancaster County were inoperable October 5 through October 9, 2001, due to a radio transmitter being deenergized at the county facility. The transmitter is part of the siren actuation system. This issue is unresolved pending further investigation into the lines of ownership and maintenance of the actuation system.” (IR 50-289/01-07).

• January 11, 2002:  Siren testing at TMI encountered numerous problems: all sirens failed in York County and one siren failed in Lancaster County. AmerGen attributed to computer malfunctions.

• March 3, 2002: A siren malfunctioned in York County again. During TMI’s annual test on on January 30, 2002, all 34 sirens in York County, located within ten-miles of the plant, failed to activate.

Good Day:

David Wright, the co-director of the Global Security Program at UCS and one of my bosses, posted commentary on the draft spent fuel storage study released earlier this week by the NRC. David's post is online at: http://allthingsnuclear.org/new-nrc-study-shows-benefits-of-transferring...

UCS plans to submit formal comments on the draft study to the NRC before the ongoing 30-day comment period ends.

Thanks,

LONDONDERRY TOWNSHIP, PA (June 25, 2013) – Three Mile Island, in cooperation with the counties around the plant, will conduct two separate tests of its emergency notification siren system on Thursday, June 27.

The first sounding will occur at 12:15 p.m. (EDT) and will test the original siren system. The second test will take place at 1:15 p.m. and will test the new, upgraded siren system that Exelon has installed. The new system includes battery backup capability that allows the sirens to sound even during power outages. The test of the new system is part of the process to gain Federal Emergency Management Agency approval to place the system in service.

The Honorable Allison M. Macfarlane
Chairman
U.S. Nuclear Regulatory Commission
Washington, DC 20555

Dear Chariman Macfarlane:

In the wake of the nuclear power plant accident in Japan, I called on the Governmental Accountability Office (GAO) to produce a report on safety preparations and emergency procedures in the event of an incident at a nuclear power plant in the United States. The GAO report, released this month, makes clear that the U.S.  Nuclear Regulatory Commission (NRC) must study the public's understanding of emergency preparedness outside the standard 10-mile emergency planning zone around nuclear power plants.

Dear Senator Casey:

 

On behalf of the U.S. Nuclear Regulatory Commission (NRC), I am responding to your letter of April 24, 2013, regarding the recent Government Accountability Office (GAO) report entitled “Emergency Preparedness: NRC Needs to Better Understand Likely Public Response to Radiological Incidents.” You expressed particular interest in ensuring that the Federal Government understands how “shadow evacuations” of populations outside the 10-mile emergency planning zone (EPZ) around a nuclear power plant would impact the evacuation times for those closest to the plant. A shadow evacuation is the evacuation by persons outside of any officially declared evacuation zone.

ACTION ALERT
Demand Enforcement of Nuclear Power Fire Safety Regulations

Dear Craig,

Last week, Dave Lochbaum, the director of the UCS Nuclear Safety Project, wrote to your governor about a very serious risk at the nuclear power plants in your state and dozens of others nationwide. He asked your governor to speak out—and we hope you will as well.

The risk is fire and the complete failure of the Nuclear Regulatory Commission (NRC) to enforce critical fire protection regulations.Today, 46 nuclear reactors, almost half of the U.S. nuclear fleet, continue to operate despite being in violation of these regulations, which the NRC first adopted more than 30 years ago—after a dangerous fire at Alabama's Browns Ferry plant—and then updated in 2004.

The NRC estimates that the risk of reactor meltdown due to fire is about 50 percent—roughly equal to all other risk factors combined. Yet the NRC has repeatedly failed to enforce fire regulations, opting to grant extensions rather than issue violation notices—including at Browns Ferry.

It is simply unacceptable that an agency that is supposed to protect the public is allowing these "nuclear crimes" to continue. And, as such, we asked your governor to write to the NRC and demand that the agency enforce its fire safety regulations and establish a clear, realistic timeline for compliance by all reactors.

We think action is more likely if you ask your governor to get involved and speak out on this common sense issue that impacts your family and community's health and safety.

Take action today! Urge your governor to demand that the Nuclear Regulatory Commission enforce its fire safety regulations.

 

Sincerely,

Sean Meyer
