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.

Subject: (4) 1" x 3.25" Capsrews
Wolf Creek Charging Pump
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.

On 10-4-94 Ingersoll-Dresser Pump had ordered four (4) 1" X 3.25" screws
from Energy & Process Corporation on purchase order 0000077767 (copy
attached). We received the 1" X 3.25" screws shipped direct from
Cardinal and used them on Wolf Creek Order 554937 for a Charging Pump,
S/N 0194012, which was shipped to you early in '95.
Attached for your review is a copy of the purchase order to Energy &
Process Corporation, a copy of the NPV-1 form for pump S/N 0194012, the
Cardinal M.T.R. for heat code K7, and the data from Energy & Process
Corporation.
