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, 21246-8 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) plecos 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, l.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.
Yours truly, V

Wolf Creek Charging Pump IDP Model 2x10 CAM-12 l
ET Ref: Your 21 May 1996 Letter E # Innersoll-Dresser Pump Company to Wolf Creek The 1" x 3.25" capscrews supplied by Cardinal Industries and l
fdistributed by Energy & Process Corporation (IDP PO 0000077767) were l
used as motor mounting bolts for the 2x10 CAM 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 l
yield strength.
The motor mounting bolts are not subjected to any operational or design loads, except during a seismic event. However, the magnitude of this loading should not be sufficient enough to induce bolt failure. However, if l
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 it's pressure boundary components. The pump / motor would remain operational throughout this worse case failure l
mode.
Based on the above, no immediate actions are required. Unless they l
fail during installation these bolt should last indefinitely. As a precan n, the next time the motor is removed from the pump baseplate these bolts should be J
replaced.

potential 10CFR21 notification. The issue involves capscrews with a trace code of K7 that were manufactured by Cardinal Industries and distributed by Energy

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