Subject:  Potential 10CFR Part 21 Notification from Energy & Process

          Corporation



On May 17th, I received a phone call from Ed Thorton, Quality Assurance

Representative from Energy & Process Corporation, 21246-B Flintstone

Drive, Tucker, Georgia 30084-5000, who informed us of a potential 10CFR21

notification.  The issue involves capscrews with a trace code of K7 that

were manufacturer by Cardinal Industries (now known as Accutech), 3873

West Oquendo, Las Vegas, Nevada 89118-3098 and distributed by Energy &

Process Corporation.  These capscrews were from two (2) lots of material

whereby, out of 71 pieces hardness tested, six (6) pieces failed.



On 10-4-94 Ingersoll-Dresser Pump Company (IDP) ordered four (4) 1" X

3.25" capscrews from Energy & Process Corporation.  We received the 1" X

3.25" capscrews with heat code K7, heat number 8866807, I.D.  MR# 77767-1

which were shipped directly from Cardinal Industries to IDP.  We used

those capscrews on Wolf Creek Order Number 554937 for a charging pump S/N

0194012 which was shipped early 1995.



After evaluation of the capscrews by IDP's Engineering Department, it was

determined that the pump/motor would remain operational throughout the

worst case failure mode.  I have attached my 21 MY 96 letter to Wolf

Creek and also a copy of Ingersoll-Dresser Pump's Engineering Analysis of

the capscrews dated 30 MY 96.



If you wish to call me concerning any of the above information, please

feel free to do so.  I can be reached at (908) 859-7603.

                                             IDP Model 2x10CAM-12



                                        Ref : Your 21 May 1996 Letter

Ingersoll-Dresser Pump Company                to Wolf Creek



     The 1" x 3.2511 capscrews supplied by Cardinal Industries and

distributed by Energy & Process Corporation (IDP PO 0000077767) were used

as motor mounting bolts for the 2x10CAM charging pump.  Under normal

circumstances, the only load on these bolts is from installation torque

resulting in a stress value which is less than 20% of the material's

specified yield strength.



     The motor mounting bolts are not subjected to any operational or

design load, except during a seismic event.  However, the magnitude of

this loading should not be sufficient enough to induce bolt failure.

However, if bolt failure were to occur, the worse case scenario would be

two of the four motor mounting bolts failing during a seismic event.

This scenario would not results in any damage to the pump or its pressure

boundary components.  The pump/motor would remain operational throughout

this worse case failure mode.



     Based on the above, no immediate actions are required.  Unless they

fail during installation these bolt should last indefinitely.  As a

precaution, the next time the motor is removed from the pump baseplate

these bolts should be replaced.
