Tokyo Electric Power Company has admitted that one reason radiation is getting into the Pacific Ocean, is that their silt fence barriers keep failing.  Today, the radioactive silt barrier failed near Fukushima Daiichi’s Reactors 5 and 6.

This is not the first time, TEPCo revealed another barrier failed five months ago.

What TEPCo calls silt fences are underwater barriers meant to contain silt contaminated with radiation from spreading into the Pacific Ocean.

TEPCo officials blame strong waves for repeatedly breaching the barriers.

Silt fences are typical of construction sites that need to protect areas of water, sometimes called filter fences.  However, experiences with silt barriers show they do not last long and fail for a variety of reasons.   One source even pointed out that silt fences do not work well in strong currents.
