US DOE chooses “Sensible Photonics” and “Guided Wave” to detect damaged nuclear waste canisters at San Onofre using ultrasound

The U.S. Department of Energy is attempting to use sound waves (ultrasound) to monitor wear and tear on canisters that store deadly radioactive spent nuclear fuel at the failed San Onofre Nuclear Generating Station (SONGS).  A full scale demonstration of the sound wave technology is expected to occur at the San Onofre Nuclear Waste Dump* sometime in 2027. 

Now, two companies, Guided Wave, and Sensible Photonics, have been selected by the Department of Energy’s Center for Used Fuel Research at Idaho National Laboratory.  The companies are claiming to specialize in a nondestructive “ultrasonic” testing of nuclear waste containers that could be used to detect problems at the facility.

Each row contains a vented cover housing a silo with a canister inside it.
Rows of vents at San Onofre cover 72 below-ground concrete silos.  Each silo has a giant stainless steel canister of nuclear waste, weigh 104,000 pounds inside of it. 

 In 2010, the beachfront San Onofre nuclear waste dump was one of America’s biggest nuclear power plants.  The plant failed when it leaked deadly ionizing radiation into the atmosphere on January 31, 2012.  The leak was from an “RSG” or Replacement Steam Generator that had an untested experimental design.  Edison’s experimental  design was not approved or licensed by the Nuclear Regulatory Commission.  As a result, SONGS could not be safely restarted because of Edison’s failure to obey the law.  

As a result of Edison’s greed and reckless engineering standards, more than 3.5 million pounds of stranded nuclear waste (“spent nuclear fuel”) is being stored 100 feet from the beach in thin-walled stainless steel canisters at San Onofre.

The  Idaho National Laboratory’s Center for Used Fuel Research hopes it will become a mecca for research designed to extract money and energy from spent nuclear fuel, and most importantly to develop “aging management” programs for the deadly radioactive material as required by 10 CFR Part 72.

In a June 2 announcement. Idaho National labs said “Automated and continuous monitoring and inspection approaches could streamline aging management activities and reduce operational burdens for used nuclear fuel management.”

The demonstration at SONGS will use a replica test canister called a “coupon” for the tests.  The coupon does not contain radioactive spent fuel, but it is equipped with electric heaters to simulate actual loading  conditions, where temperatures can reach 500 degrees F or more.

What Edison fails to mention is that standing next to the sidewall on a fully loaded canister without radiation protection is lethal  The reason for this is that the cans at San Onofre have walls that are only 5/8″ thick.  The cans are made of industrial strength stainless steel, but the radiation passes through the walls like water through a piece of cheese cloth.

The so-called “spent nuclear fuel” at San Onofre will remain deadly for at least 25,000 years.  The nuclear waste canisters at San Onofre have a ten year limited warranty.

What do you think?  Is a ten-year warranty “good enough?”

* The NRC prefers to refer to its Nuclear Waste Dumps as “Independent Spent Fuel Storage Installations” or “ISFSIs.”  The use of this type of excessively complex nomenclature is designed to keep people like you from understanding what the NRC is actually talking about.
