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.

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.
