An air-monitoring alarm went off at 11:30 p.m. local time Friday indicating unsafe concentrations of radiation inside the Waste Isolation Pilot Plant in what DOE officials said appeared to be the first such mishap since the facility opened in 1999.
As of Sunday, the source of the high radiation readings had yet to be determined, and a plan to send inspection teams below ground to investigate was put on hold as a precaution.
“They will not go in today. It’s a safety thing more than anything. We’re waiting until we get other assessments done before we authorize re-entry,” DOE spokesman Bill Mackie said.
The facility, located in southeastern New Mexico near Carlsbad, is designed as a repository for so-called transuranic waste, which includes discarded machinery, clothing and other materials contaminated with plutonium or other radioisotopes heavier than uranium.
