The U.S. National Nuclear Security Administration has continued transferring staffers following July's high-profile infiltration of the Y-12 National Security Complex in Tennessee, the Knoxville News Sentinel reported on Thursday.

The three members of the antiwar group Transform Now Plowshares on July 28 passed into the Oak Ridge nuclear arms facility's "Protected Area" -- the plant's most heavily guarded section and home to atomic arms activities and bomb-grade uranium storage -- and reportedly dumped blood, put up placards and painted wording on the sides of structures prior to their detention.

Multiple assessments are now under way "to gain a better understanding of how and what happened, and where we collectively need to go from here," NNSA Administrator Thomas D'Agostino and Principal Deputy Administrator Neile Miller said in a statement to personnel at the semiautonomous Energy Department agency.

The assessments would consider protective procedures across the entire Energy Department, he said.

Separately, the Y-12 site's private security provider had yet to provide new responsibilities to three one-time leaders pulled from their posts since the July incident, according to the newspaper.

The Energy Department is expected on Friday to formally solicit offers for overseeing defenses at three of its other Oak Ridge sites, the News Sentinel reported.
