Dresden Procedure DRP 1480-01, Revision 9, "Contamination
Surveys," states that any material exiting the controlled area
must be given an unconditional release unless only fixed
contamination is present and the material bears a radioactive
material label or tag. Contrary to this, on or around November 2,
1992, an unconditional release was not given for a valve and other
pieces of metal that were found in the mechanical maintenance shop
outside the controlled area. These items were not labelled or
tagged and had smearable contamination that ranged from 500
disintegrations per minute (dpm} to 20,000 dpm.
In addition, on
or around February 2, 1993, an unconditional release was not given
for two contaminated work gloves found alongside the road leading
to the station. These gloves were not labelled or tagged and had
fixed contamination that ranged from 200 to 5000 dpm {Violation
No. 50-237/93007-02b(DRSS); 50-249/93007-02b{DRSS}).
Although
these problems were identified by the licensee, corrective actions
for several similar problems earlier in 1992 should have precluded
them.

Dresden Procedure DRP 1520-13, Revision 2, "Loading and Shipping
Radioactive Protective Clothing," states that the Station Laborer
group will not load any laundry bag that has a contact reading
greater than 25 mrem/hour into laundry shipping containers, but
will set it aside for followup surveys by radiation protection
personnel.
Contrary to this, on or around January 16 and 27,
1993, one laundry bag reading 115 mrem and one bag reading 111
mrem were not set aside, but were found loaded in boxes for
shipment to an offsite nuclear laundry (Violation No. 50-
237/93007-02c(DRSS); 50-249/93007-02c(DRSS}).
Although these
problems were identified by the licensee, they should have been
precluded by* corrective actions for a similar problem discovered
on December 16, 1992, where a laundry bag reading 3 rem/hour was
found in a shipment box.
d.
The licensee informed NRC personnel that on February 13, 1993, a
station electrician and a CRPT were in a restricted area without
authorization during radiography.
The radiography was being
conducted by a State of Illinois-licensed company using a 54-curie
Iridium-192 source. Dresden personnel tentatively determined that
the two individuals had not signed any Radiation Work Permit prior*
to entering the area, but were wearing thermoluminescent
dosimeters.
The exposure of the electrician was determined by
plant staff to be 15 mrem and that of the CRPT to be 30 mrem.
NRC
personnel informed the State of Illinois of the event.
The
licensee stated that the CRPT had been terminated and that the
electrician had received a two-week suspension from work.
The
results of the licensee's investigation will be reviewed during a
future inspection (Unresolved Item No. 50-237/93007-03(DRSS); 50-
249/93007-03(DRSS)).
One violation of NRC requirements and one unresolved item were
i dent ifi ed.
