corrective action. appeared. appropriate. 1However, since this event is similar to other recent occurrencas as described in;
'Section 3.7, the long term corrective' action"is still1under management review.
The Human' Performance Evaluation Survey-was still-in-progress.
The inspector-concluded that this was reasonable considering the need'to consider the other, j

similar events.

The-inspector's review indicated,that the. differences.in'

The licensee's/ program _for-

A significant effort.was. underway;to reduceLthe number ofL

personnel contamination events.:
Contaminated areas.in the:

reactor building were being= decontaminated and-painted'.
An:

Building was excellent.
There was a "LoveliTech" assigned

In addition, there were " Job coverage Techs" assigned to each' job in progress and a " Rover-Tech" who conducted spot-audits throughout the-building and assisted as'necessary.-
