1.0 PURPOSE AND SCOPE

1.1 Purpose

This procedure provides instructions for using CPN Model 503DR Ml HP-2 or Ml HP-3

Hydroprobe at an assigned tank farm vadose zone borehole/drywell or for obtaining data

for Hydroprobe-Neutron Source performance verification.

This procedure can be performed in multiple locations. A work area and/or location

specific hazard analysis must be performed prior to starting the activity per

TFC-ESHQ-S_SAF-C-02.

1.2 Scope

This procedure applies to the setup of the Hydroprobe for borehole/drywell logging,

operating, and obtaining and transferring borehole/drywell data from the Hydroprobe to a

computer.

1.2.1 This procedure also applies to obtaining data for Hydroprobe-Neutron Source

performance verification.

2.0 INFORMATION

2.1 Terms and Definitions

ORRSR - Onsite Routine Radioactive Shipment Record

2.2 General Information

3.0 PRECAUTIONS AND LIMITATIONS

3.1 Personnel Safety

WARNING - Attempting to catch and regain control of the probe and cable if it slips

free during removal or insertion into the borehole/drywell could result in

personnel injury.

WARNING - Failure to handle the probe and source carefully or keep it at a maximum

distance could result in increased Neutron exposure.

WARNING - Failure to store the neutron source in its shipping/storage container when

not in use, could result in increased Neutron exposure.

WARNING - Removal of radioactive liquid could result in the spread of contamination.

3.1.1 Use of a neutron source requires users to be qualified as Source User (Course

356424). Issue and return of this source must be conducted by a Source

Custodian or Source Custodian delegate.

3.1.2 Poor lighting conditions and snow cover may hide uneven ground, survey

stakes, digging, etc. from the view of personnel performing this procedure.

3.2 Equipment Safety

CAUTION - Performing steps in this section (5.5) while precipitation is occurring or

when considerable water or snow is present near the probe, could bias the

data obtained.

CAUTION - To obtain the most accurate readings the moisture detection system should

have a Performance Verification performed. The Performance

Verification needs to be performed with the 503DR Hydroprobe meter and

source/detector together.

3.3 Radiation and Contamination Control

3.3.1 The neutron source is to be stored in its shipping/storage container when not

in use.

3.3.2 Cleanliness check swabs will be controlled as radioactive material after use

and will be surveyed by a Health Physics Technician (HPT) prior to exiting

the farm.

3.3.3 Removal of contaminated liquid requires HPT coverage and cannot be

performed using the long term Radiological Work Permit that permits routine

drywell logging/monitoring activities.

3.3.4 Failure to handle the probe and source carefully or keep it at a maximum

distance could result in increased Neutron exposure.

3.3.5 When this procedure is worked in radiological areas, an approved

radiological work permit (RWP) is required. If radiological conditions or

work performed falls outside the scope of the RWP, all work activities must

be discontinued until a new or revised RWP has been issued in accordance

with TFC-ESHQ-RP_RWP-C-03.

3.4 Environmental Compliance

3.4.1 If borehole/drywell is found to be contaminated during use of this procedure,

Environmental must be notified per the Environmental On-Call List.

3.4.2 The following controls specified in the appropriate section of

TFC-ESHQ-ENV-STD-06, As Low As Reasonably Achievable Control

Technology (ALARACT) Requirements Standard, are applicable:

At a minimum, pre- and post-job surveys shall be taken and

documented on a Radiological Survey Report.
