LAS VEGAS (AP) - A small percentage of nuclear waste containers is expected to arrive at Yucca Mountain with undetected leaks and cracks, potentially exposing workers at the proposed repository to high levels of radioactive contamination, the Las Vegas Review-Journal reported Saturday.
Without special precautions, spent nuclear fuel contained in these damaged tubes could trigger chemical reactions when extracted from protective canisters in preparation for long-term storage, according to an Energy Department study obtained by the newspaper under the federal Freedom of Information Act.
Completed in March by DOE and outside engineers, the study concluded the department had not fully evaluated the hazards associated with handling damaged fuel at the site, nor designed a process for effectively managing it.
"It is rather late in the day for these people to be thinking about this stuff," said Arjun Makhijani, a nuclear engineer and president of the Institute for Energy and Environmental Research. "It is truly astonishing that they have not thought about this issue thoroughly a quarter of a century after serious work on repositories began." <snip>
