SAMPLE OPERATIONS ASSESSMENT REPORT

FINDING:

Two Radioactive Material Areas were unnecessarily established inside Contamination Areas.

(Reference: 1)

DISCUSSION: A Radioactive Material Area (RMA) has been established inside the 106C

tent located in C-Farm, a Contamination Area. A RMA was established inside the 244A lift

station Contamination Area. This posting is not required by the HSRCM. To minimize

unnecessary exposure and generation of radioactive waste, WHC should not post RMAs

inside contaminated areas.

FINDING:

Anti-C doffing procedures posted at four out of four East Tank Farm exits observed, did not

reflect all appropriate undressing instructions. (Reference: 1) [Concern: 6]

DISCUSSION: The removal sequence of Personal Protective Clothing for the DCRT cover

block removal included removal of respiratory protection first. This sequence was not

reflected in undressing procedures.

Interviews with personnel indicated that a double set of Personal Protective Clothing (PCS)

is used in some instances at the tank farm. The standard sign for undressing does not include

the sequence for removal of double PCS.

The undressing procedure does not address removal of tape on inner gloves that is covered

by the outer gloves. The procedure only discusses removal of exposed tape prior to

removing outer gloves. Several workers were observed pulling the coveralls off with the

inner gloves still taped to the outside of the coverall.

FINDING:

Buffer Area adjacent to X Tank Farm was not properly posted. (Reference: 1) [Concern: 6]

DISCUSSION: The buffer area adjacent to X Tank Farm entrance was posted as a

contamination area on two sides. A contamination area sign was posted on the fence

bordering the buffer area outside the Tank Farm. The contamination area sign on the rope

between the buffer area and Tank Farm contamination area was facing the wrong direction,

indicating the buffer area was a contamination area. The buffer area sign on the rope was

hanging by one end.
