Most important deliverable for containment is to hire, train, and certify new containment geologist and containment scientists. Right - The Nevada Test Site where the vast majority of US nuclear tests were conducted is being maintained in the event of a return to testing. Right - The massive venting from the Livermore underground nuclear, Baneberry, conducted in 1970, led to the initiation of underground test containment programs at Los Alamos and Livermore. The Los Alamos containment program maintained a perfect containment record until the testing moratorium in 1992. Right - As part of the test readiness program, Test Exercise Alpha was completed in 1991. For the exercise, the containment program selected an event hole and depth of burial, characterized the site, and made predictions about expected phenomenology.
