3. Identification of the Firm supplying the basic component
PYCO Inc.
600 E. Lincoln Hwy.
Penndel, PA 19047
4. Nature of Deviation
RTD assemblies were manufactured using a screw cover terminal
enclosure fabricated from aluminum instead of an identical
appearing cast iron enclosure as specified on the assembly
drawing.
5. Date Detected:
Niagara Mohawk returned S/N 15007 to PYCO for calibration
verification (RMA4040). The nonconformance was discovered
during our in-house receiving, inspection of customer returned
materials on September 19, 1997. The calibration verification
was completed on September 26, 1997 and the RTD's are within
specification. Verbal communication of the discovery of the
nonconformance was provided to Niagara Mohawk on September 29,
1997. Since two RTD's were manufactured in SO# 57985, PYCO
informed Niagara Mohawk of the other RTD, assembly (S/N 15006)
that could have been manufactured with an aluminum enclosure.
PYCO requested Niagara Mohawk to inspect S/N 15006 and advise
PYCO of their results for corrective action development, as
required.

Mohawk PYCO to provide Cast Iron enclosure and installation
instructions to Niagara Mohawk for replacement at site
location.
B. S/N 15007 - Rework the RTD assembly, replacing the
aluminum enclosure with a cast iron enclosure, inspect and
return to Niagara Mohawk,
C. Review and update PYCO's Commercial Grade Item (CGI)
dedication procedure to preclude recurrence.
8. Advice Related to Deviation;
Both the Aluminum and Cast Iron enclosures are APPROVED for use
in Nuclear Applications as verified by Qualification Tests and
are routinely used in Nuclear Power Plants.
Sincerely,
