[ RadSafe ] Unplanned Radiation Exposures at Cooper Nuclear Plant

Here's a recent NRC press release regarding an incident at Cooper. It is
receiving media coverage. I'd be interested in the results of the
investigation, in particular: Was the job poorly planned? or Did the
workers not follow procedures? Since most plants plan work down to the
man-millirem, I suspect the latter.
*NRC SENDS SPECIAL INSPECTION TEAM TO COOPER NUCLEAR STATION
The U.S. Nuclear Regulatory Commission has begun a special inspection at the
Cooper Nuclear Station to review the circumstances surrounding a maintenance
procedure that led to unplanned radiation exposures to three workers. The
plant, located near Brownville, Neb., is operated by the Nebraska Public
Power District (NPPD).
Inspectors, who began their work Monday, will look at the circumstances and
decision-making by NPPD officials that led to the exposures, review the
licensee’s response to the event, calculate the exposures the workers
received and review corrective actions taken to prevent a recurrence.
The incident occurred on April 3, when workers removed a long tube
contaminated with highly radioactive material through the bottom of the
reactor vessel, rather than through the top as is usually done, triggering
radiation alarms. The workers set the tube down and immediately left the
area. The licensee does not believe the workers received radiation exposures
in excess of NRC limits.
“We want to understand why normal work practices were not followed,
resulting in unplanned radiation exposures to three workers,” said Region IV
Administrator Elmo E. Collins. “We want to take a look at the
decision-making that contributed to this event.”
The team consisting of two NRC inspectors, began work Monday and will
probably spend several days at the plant. They will write an inspection
report on their findings within 45 days of the end of the inspection that
will be made publicly available.*
It's not about dose, it's about trust.
