Areas Inspected:

A special, unannounced inspection was conducted in response to

allegations of violations of regulations and operating procedures and unsafe

practices.

personnel, and a visit to company headquarters to review records of personnel

4

monitoring, source utilization, survey instrument calibration, and personnel

training.

The inspection involved 6 inspector-hours onsite by one NRC inspector.

'

A third allegation was proven to be correct, that of vehicles carrying radio-

active sources not being placarded with DOT signs; however, this proved not to

Reason for Special Inspection

On November 11, 1985, the Region IV allegations coordinator received an

anonymous call from an individual alleging unsafe practices and violations

of operating procedures and regulations by workers performing radiographic

work for H & G Inspection Company, Inc., in the Shute Creek area of Wyoming.

Of the allegations made, five were related to regulations or license condi-

tions and would be under the jurisdiction of the Commission.

The five

allegations were:

(1) Unqualified personnel were working as radiographers

and assistant radiographers, (2) Survey instruments were being used when

not in calibration, (3) Utilization records were. altered to indicate that

instruments used were in calibration when they actually were not,

(4) Trucks transporting radioactive sources were not properly placarded

with DOT signs, and (5) Individuals performing radiography had been over-

exposed to radiation because of a source disconnect.

3.

Field Inspection

On the night of November 13, 1985, the NRC inspector visited the site of

-

the Exxon plant in the Shute Creek area of Wyoming.

Both the night super-

-

visors for Exxon and their prime contractor, Project Construction Company

i

(PCC) were contacted upon arrival, in order to gain access to the

construction area.

The NRC inspector stated that he wished to perform an

unannounced inspection of H & G Inspection Company.

Both representatives

gave their complete support.

The NRC inspector was taken by a PCC representative to the first site where

'

radiography was being performed.

The area was roped, but no signs were

posted. This was identified by the NRC inspector as a violation of 10 CFR

,

i

34.42. -The radiographer was working on an elevated section of pipe.

Two

other individuals were maintaining surveillance on the ground and kept the

NRC inspector and PCC employee from entering the restricted area.

The NRC

inspector observed the radiographer perform an exposure and return the

source to its shielded position.

The radiographer did not have a survey

instrument with him and therefore did not make a survey of the exposure .

device after completing the exposure.

This was identified by the NRC

inspector as a violation of 10 CFR 34.43(b).

.

The NRC inspector identified himself to the work crew and asked to examine

personnel monitoring devices.

The radiographer and one assistant carried

both film badges and pocket dosimeters.

The second individual carried

neither.

This was at first identified as a violation of 10 CFR 34.33(a);

however, observations were insufficient to establish conclusively that the

individual had indeed been performing the duties of assistant radiographer.

The licensee stated that the individual'had just arrived at the job site

and had merely gone to introduce himself to the person with whom he would

be working and had actually not performed the duties of assistant radio-

grapher. The individual had previously stated the same thing to the NRC

inspector. This item was not cited, although it was discussed with the

i

licensee as an area of concern.

The NRC inspector asked ~to see the survey instrument that was being used.

The radiographer questioned the assistant and, after a few minutes, the

assistant produced an instrument which he said he had lef t on.the ground

nearby.

The instrument was in calibration.

The NRC inspector asked to see the survey records for the current job and

~

i

found that surveys had not been done.

This was identified by the NRC

inspector as a violation of 10 CFR 20.201.

A second crew was observed and was found to be following proper procedures

with the exception of inadequately surveying the exposure device by not

surveying the guide tube after each exposure.

This was identified as a

second example of a violation of 10 CFR 34.43(b).

The vehicles observed by the NRC inspector were placarded with DOT signs.

In response to the NRC inspector's questions, the licensee stated that two

of the vehicles being used to transport licensed sources at the work site

were not placarded with DOT signs.

He also stated that material was stored

at the site and not carried on roads offsite and that material was shipped

to the site originally, either by common carrier or one of the other

,

properly marked vehicles.

None were observed on the highways.

Allegation #4 was substantiated, but there was no violation.

-

The company president was onsite and stated to the NRC inspector that there

had been an incident which resulted in the overexposure of one individual.

Details are listed in the next section.

Inspection of Records at Home Office

On November 21, 1985, the NRC inspector went to Houston to inspect records

unavailable at the field office.

Records for training of radiographers included any previous training and

experience, the training course given by the company's consultants, written

!

tests, and the results of practical testing. The only records available

!

for assistant radiographers were signed statements attesting to the fact

that they had received and reviewed. copies of the operating procedures and

a copy of written exams given after their first day's orientation. No

record of practical training was available.

Records for the several

'

radiographers, picked at random from an employee list, were available.

Allegation-#1 was not substantiated.

Records of utilization were reviewed by the NRC inspector. On the records

were blanks on which the user could indicate the serial number of the

survey instrument used and indicate whether or not it had a current

calibration.

The NRC inspector noted that'on several occasions instruments

not calibrated within the previous 90 days had been used.

As an example,

instrument, serial number 1905, was used on November 6, 1985 (the time of

the apparent exposure).

It was last calibrated on July 24, 1985.

This

was identified by the NRC inspector as a violation.of 10 CFR 34.24.

Allegation #2 substantiated.

Although some examples of utilization records were incomplete as to whether

or not the survey instrument used was in calibration, no examples of

altered records were observed.

Allegation #3 not substantiated.

The NRC inspector reviewed the personnel monitoring report showing that

one individual had received an exposure of 3.4 rems for the period of

October 19, 1985, the individual's first day of work, to November 6, 1985,

the day of the incident.

This was identified by the NRC inspector as

a violation of 10 CFR 20.101.

According to Texas' equivalent form to NRC

Form 4, the individual had no previous experience or radiation exposure.

Allegation #5 substantiated.

The NRC inspector reviewed the licensee's evaluation of the'cause of the

exposure and found that signed statements from the individuals involved

l

indicated that it was due to a source not being fully retracted to its

shielded position (not a source disconnect) and going undetected because an

adequate survey was not performed.

The lack of an adequate survey was

'

identified by the NRC inspector as another example of a violation of 10 CFR

'34.43(b).
