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

Attach.

IDENTIFICATION OF THE FACILITY, THE ACTIVITY, OR THE BASIC COMPONENT
SUPPLIED FOR SUCH FACILITY OR ACTIVITY WITHIN THE UNITED STATES WHICH
FAILS TO COMPLY OR CONTAINS A DEFECT:

          Basic Component:    6-inch 150# Gate Valve (401KBB3-004)
                              S/N 62039

                                                            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.

                                                                 Page 2

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.
