Over at IEEE Spectrum, another in-depth article on problems at the Hanford Site in Eastern Washington state. This essay deals with problems found in the “nearly 2,000 capsules of highly radioactive cesium and strontium” kept in a facility known as “Waste Encapsulation and Storage Facility (WESF).”
“Built in 1973, the facility is well beyond its 30-year design life. In 2013, nuclear specialists in neighboring Oregon warned that the concrete walls of the pools had lost structural integrity due to gamma radiation emitted by the capsules.”
After reading the above linked article, you will be ready to watch some effective DOE/CH2MHILL propaganda:
