• Interval selection
• Determining component acceptability
4.0 RESPONSIBILITIES
4.1 Administrator of IR – It is the administrator’s responsibility to oversee the program. This
includes making changes to the procedure. All surveys, whether they are scheduled or
conducted on an emergency basis, shall be approved by the administrator or his/her
designee. The administrator shall be responsible for budgeting, planning, and interfacing
with outside organizations.
4.2 Infrared Thermographer – The infrared thermographer is the only person trained and
qualified to operate the infrared imaging equipment. He/she is responsible for conducting
the surveys, interpreting the images, writing the reports, and acting as a technical
resource to other plant departments. The infrared thermographer is responsible for the
maintenance and calibration of the infrared imaging equipment.
4.3 Cognizant Engineer – At the request of the infrared thermographer, a discipline-cognizant
engineer will provide assistance in diagnosing a problem. The cognizant engineer will
also suggest corrective action and provide coordination with other plant disciplines.
4.4 Root Cause – Determination of root cause and the subsequent applicable action level
shall be the responsibility of plant management. When necessary, the infrared
thermographer shall request assistance from a cognizant systems or maintenance engineer
in determining the root cause or the recommended corrective action.
5.0 PRECAUTIONS
5.1 Many of the components that are being inspected represent potential plant trip hazards;
exercise extreme care.
5.2 All safe work practices as outlined in the plant safety manual, shall be followed. These
practices include exhibiting caution near energized electrical equipment, rotating
equipment, and hot pipes. All surveys shall be conducted from a safe stable location.
5.3 Infrared surveys within the Radiological Controls Area shall be conducted within the
guidelines of the Health Physics Department. In areas of potential contamination, the
infrared thermographer shall be responsible for covering the equipment with plastic as
directed by Health Physics.
5.4 When practical, surveys in areas of airborne contamination should be avoided. When this
is not possible, a thin piece of polyethylene or plastic can be placed over the lens. If this
is done, the transmittance of the covering must be taken into account.
6.0 PREREQUISITES
6.1 Personnel – The infrared thermographer and one craft person constitute the minimum
personnel necessary to conduct a survey when the operating or opening of equipment is
necessary.
