3.1 D iscussion
The control and calibration of measuring and test equipment (M&TE) plays an ever
increasing role in the safe operation of DOE Nuclear Facilities. The need to ensure proper
calibration and traceability of use has increased. Therefore, implementation of an M&TE
control and calibration program is essential. A computer based sy stem should be considered
for the establishment of an M&TE program.
This guideline establishes a process to ensure that M&TE is properly controlled,
calibrated, and certified with standards and data traceable to NIST.
The M&TE program shall be comprehensive and ensure the following:
All M&TE is uniquely identified, calibrated, controlled, and provides accuracy
A recall program maintains the total inventory and status of all M&TE.
Out-of-tolerance M&TE is removed from service.
Plant equipment calibrated with out-of-tolerance M&TE is evaluated in a timely
manner for impact on previous output, current operability and is re-calibrated as
The critical parameters of all M&TE such as range, precision, accuracy, etc. are
documented; the documents shall be retrievable, and maintained as quality records.
M&TE intended only as an indicator during troubleshooting and not intended for
calibration or data measurement should not be required to display calibration/certification
The M&TE program should be regularly evaluated to:
Detect trends which adversely affect safe, reliable use of equipment
Determine opportunities for expanded applications of equipment
