SAMPLE OPERATIONS ASSESSMENT REPORT

FINDING:

The radiological control posting inserts that describe entry requirements were found missing on

four signs. (Reference 1) [Concern: 6]

DISCUSSION: The entry requirements insert for a Contamination Area sign located on the

east side of C-Farm was missing.

Entry requirement inserts on two High Contamination/Radiation Area signs inside C-Farm

were missing. The sliding pieces were adrift near the area.

The entry requirement insert was missing for a Contamination Area sign located on the NE

side of A-Farm, on a barrier around a valve station.

Two Radioactive Material Area signs posted on the entrances to an RMA located near the

Bldg.272-AW WRAM station had pieces of paper with hand written information in the insert

pocket.

FINDING:

Several scan surveys using Portable Alpha Meters (PAM) were improperly recorded as having a

MDA of 20 DPM/100cm2. (Reference 1)

DISCUSSION: A scan survey using a PAM can not detect contamination levels as low as

20 dpm alpha. During an observation of radiological control technician routine surveys,

alpha levels measured with a PAM were recorded as less than 20 dpm. A review of other

survey records indicated similar survey level errors.

FINDING:

One potentially contaminated tool was found packaged in clear plastic at the 244-A lift station.

(Reference: 1) [Concern: 6]

FINDING:

During a gasket replacement in a section of contaminated piping, the procedure did not specify

radiological hold points. (Reference: 1) [Concern: 7]

FINDING:

During a gasket replacement in a section of contaminated piping, an RCT only took swipes before

and after the work, but the RCT did not take any swipes while the interior surfaces of the pipe

and flange were exposed. (Reference: 1) [Concern: 7]
