Subject: 10CFR, Part 21, Notification No. CFRN 94-01
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 94-01 submitted on 12 April, 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 6 May 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:
Quantitative measurements of the referenced valve as part of the
EPRI MOV Performance Prediction Program in response to NRC Generic
Letter 89-10, showed the maximum valve friction factor to be between
0.79 and 0.88 for both valve opening and closing. These EPRI test
results appear to indicate the industry accepted standard friction
factor of 0.3, used to calculate the valve seating force, is not
conservative.
The calculated forces are used to size the valve actuator and motor
and to set the actuator torque switch. If the actual friction
factor is higher than the design value, the valve actuator and motor
may be undersized and the valve may not operate under all
conditions.
THE DATE ON WHICH THE INFORMATION OF SUCH DEFECT OR FAILURE TO
COMPLY WAS
OBTAINED:
EPRI completed testing of the referenced valve on 20 July 1992 and
notified BW/IP of the findings on 31 July 1992.
BW/IP initiated an evaluation to determine if a reportable
deficiency existed. This evaluation involved significant re-testing
of the valve used in the EPRI test as well as similar valves for
comparison. These tests were completed in February 1994. Results
show the actual valve friction factors to be in the range of 0.4 to
0.6.
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 Borg-Warner
gate 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 gate valves and take
corrective actions as appropriate.
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.
