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

traceability.

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

necessary.

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.

Process repeatability.

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

identification.

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
