VENDOR: Wyle Laboratories PT21 FILE NO: m2-08-0
DATE OF DOCUMENT: 04/12/02 ACCESSION NUMBER: ml021060181
SOURCE DOCUMENT: LETTER REVIEWER: RORP, J. Dozier
Wyle Laboratories, a procurer of irradiation services from Georgia
Institute of Technology, reported an error in irradiation dose units for
all equipment irradiated with the cobalt-60 sources in the Georgia Tech
hot cell from 7/24/1997 to 7/6/2001. Georgia Tech reported to Wyle
Laboratories radiation doses in units of rads-air (absorbed dose in air)
instead of Roentgens. Since one Roentgen is equal to 0.877 rad, the
actual dose is less than the reported value.

Licensee/Facility: Notification:
Part 21 Database MR Number: H-02-0044
General Electric Date: 06/18/02
Subject: Part 21 - Missing lock washer on CR105X contactors
Discussion:
VENDOR: General Electric PT21 FILE NO: m2-09-0
DATE OF DOCUMENT: 04/12/01 ACCESSION NUMBER: ml021150567
SOURCE DOCUMENT: LETTER REVIEWER: RORP, V. Hodge
General Electric, a vendor of CR105X auxiliary contact devices, reported
a failure to change state caused by disengaged plunger arm and loose
plunger post that is caused by a missing lock washer. These devices are
sold safety related as a kit with convertible contacts (from normally
open to normally closed) or as part of contactor assemblies (CR105 205
and 305 series), starter assemblies (CR106, 206 and 306 series), and
controller assemblies (CR109, 209 and 309 series) that may be part of
7700 series motor control centers.
The vendor states that CR105X kits contain the lock washer but the
provided customer installation instructions are defective. The vendor
states that its records do not indicate a high incidence of failure due
to loosening of the plunger post and recommends inspection of installed
CR1 05X auxiliary contacts at the next available outage and inspection of
spare CR105X auxiliary contacts before they are used.
