Subject: 10CFR, Part 21, Notification No. CFRN 94-03
Gentlemen:
An audit of activities relative to Title 10 of the Code of Federal
Regulations, Part 21, for the 1994 calendar year has recently been
completed. The audit was unable to definitively determine whether
Attachment A, Location Of Equipment, had been sent with Notification No.
CFRN 94-03 submitted on 25 October, 1994.
BW/IP International, Inc., believes the Attachment was correctly included
with the Notification. However, there was no specific reference to
Attachment A contained in the text. All utilities with valves effected
by this Notification were individually informed of the filing and sent a
copy of the Notification on 29 October, 1994, in accordance with our
10CFR, Part 21, procedure.
To assure that the official identification requirement has indeed been
satisfied for this Notification, Supplement 1, attached, adds a reference
to Attachment A to the text and transmits the location of the affected
valves as required by 10CFR, Part 21.
Very truly yours,
D.A. Gibson
Manager Nuclear Products Operations

SUPPLEMENT 1
NATURE OF THE DEFECT OR FAILURE TO COMPLY AND THE SAFETY HAZARD
WHICH IS
CREATED OR COULD BE CREATED BY SUCH DEFECT OR FAILURE TO COMPLY:
Design calculations of stem thrust required to close the valve
were based on the differential pressure acting on the seat area
of the valve. Quantitative measurements of the referenced valve
as part of the EPRI MOV Performance Prediction Program in
response to NRC Generic Letter 89-10, showed that, when flow
through the valve exceeds 5 fps, the stem thrust should be
based on the differential pressure acting across the valve
guide area. Required stem thrust using the valve guide area can
be more than double the value calculated using the seating
area.
The calculated forces are used to size the valve actuator and
motor and to set the actuator torque switch. If the stem thrust
required to close the valve against a differential pressure is
higher than the design value, the valve may fail to perform its
intended safety function.
THE DATE ON WHICH THE INFORMATION OF SUCH DEFECT OR FAILURE TO
COMPLY WAS
OBTAINED:
EPRI completed testing of the referenced valve on 18 October
1993 and notified BW/IP of the findings on 18 October 1993.
BW/IP initiated an evaluation to determine if a reportable
deficiency existed. Prior to completing this evaluation, EPRI
reported the dependence of the stem thrust on flow velocity.
IN THE CASE OF A BASIC COMPONENT WHICH CONTAINS A DEFECT OR FAILS TO
COMPLY, THE NUMBER AND LOCATION OF ALL SUCH COMPONENTS IN USE AT,
SUPPLIED FOR, OR BEING SUPPLIED FOR ONE OR MORE FACILITIES OR
ACTIVITIES
SUBJECT TO THE REGULATIONS:
This Notification applies to all sizes and classes of motor
operated Borg-Warner Y-Globe valves.
See Attachment A for specific station locations. *

THE CORRECTIVE ACTION WHICH HAS, IS BEING, OR WILL BE TAKEN: THE NAME
OF
THE INDIVIDUAL OR ORGANIZATION RESPONSIBLE FOR THE ACTION: AND THE
LENGTH
OF TIME THAT HAS BEEN OR WILL BE TAKEN TO COMPLETE THE ACTION:
If not already done, utilities should review the set-point
calculations on all installed Borg-Warner Y-globe valves and
take corrective actions as appropriate.
BW/IP has revised the operator selection criteria for new
products.
ANY ADVICE RELATED TO THE DEFECT OF FAILURE TO COMPLY ABOUT THE
FACILITY,
ACTIVITY, OR BASIC COMPONENT THAT HAS BEEN, IS BEING, OR WILL BE GIVEN
TO
PURCHASERS:
BW/IP should be contacted for details and assistance.
