i am I I I W, lidVi!9 R At 't itA t AH (A) 4tfC ATTENTION:
ALL IR 100 OWNERS / RSOs Industrial Nuclear Company (INC) recently received information that the safety latch plate of the IR 100 !!xposure Device would bend when the safety latch plate was struck directly on the face. We had performed the horizontal shock test on the lock box in 1991, as requhed by ANSI N432-1980, Section 8.2 and tbc IR 100 passed without difficulty, The lit 100 Exposure Device has been on the market and in use since 1979. INC was concerned, however, the safety latch plate bending has never been reported to INC.
INC initiated an investigation and found that whenever the source was in the safe position with the IR 100 locked, the safety latch plate could be bent by a direct blow.
Please Note: Bendine of the safety latch ointe orevents source crank out.
llence. the safety Intch nlate bendine is not a safety issue.
Please return your IR 100 to us foi a modified safety latch plate replacement the next time you need a new so. ve. This will insure that the safety latch plate bending will not occur in the future.
Due to the nature of this modification (disassembling the lock lxxly)- we would encourage you to return the IR 100 Exposure Device to INC for the safety latch plate replacement. If you decide to return the device for the repleement, please return the nulified safety latch plate with the shipment.
If you can not return your IR 100 to us, please replace the current safety latch plate with the modified safety latch plate we have enclosed with this notice. Note: Source must be properly stored in a Source Chancer before replacing the safety latch pho.
e Please be sure to follow the detailed instructions that are enclosed. We would appreciate your returning the old safety latch plate to us.
INC has notified the California Department of llealth Si cices, Radiologic Ilealth Branch of the potential problem regarding the bending of the sa! y latch plate and they agree with our actions to replace them.
If you have any question, please call Mike Rose, E. W. " Bill" lluddleston or the undersigned at 1-80(b711-1982. Thank you very much for your cooperation in this matter.
Very truly yours,

OFFICE OF NUCLEAR MATdRIAL SAFETY AND SAFEGUARDS l
WASHINGTON, DC. 20555 December 12,1997 NRC INFORMATION NOTICE 97 87: SECOND RETROFIT TO INDUSTRIAL NUCLEAR COMPANY IR100 RADIOGRAPHY CAMERA, TO CORRECT INCONSISTENCY IN 10 CFR PART 34 COMPATIBILITY Addressega All industrial radiography licensees, Purnose The U.S. Nuclear Regulatory Commission (NRC)is issuing this information notice to make licensees aware of a retrofit to the lock of the Industrial Nuclear Company (INC) Model IR100 Radiography Camera, to correct an inconsistency in 10 CFR Part 34 compatibility. It is expected that recipients will review the information for applicability to their licensed activities, and consider actions, as appropriate, to avolo problems, However, suggestions contained in this information notice are not NRC requirements; therefore, no specific action nor written response is required.
Descriotion of Circumstances The recent retrofit to the safety latch plate (NRC Information Notice 97-35, dated June 18, 1997), which corrected a scenario where the INC Model IR100 radiography camera would not pass the horizontal shock test, as required by 10 CFR 34.20, resulted in the equipment not J
meeting the requirement that the lock should not be easily removed by unauthorized personnel.
- INC and the State of California evaluated the problem, and INC took action to correct the situation,
' Discussl0D
- The " Safety Latch P: ate" on the IR100 radiography camera has a potentially more " fragile area" (as specified in ANSI N432-1980, Paragraph 8,3.2) than the area previously tested.
Apparently,if the Safety Latch Plate was struck directly on the front surface of the plate (with the source in the safe. locked position), the plate could be deformed and deemed inoperable. It also appeared that the plate might be susceptible to damage if struck from the top and side. To.
ensure that this type of potential damage was not possibie, a bumper hat would prevent 5
n
-,,,.,,, +
-n.
.a
IN 97-87 December 12,1997 Page 2 of 2 deformation was welded to the back of the Safety Latch Plate, and the outer top edge of the plate was angled at a 45 to-50-degree angle, to a depth of approximately 3 mm (0.12 inch). The modified device was tested to ensure compliance with ANSI N432-1980, paragraph 8.2.
6 In the Safety Latch plate retrofit to the IR100, the Allen screws used to fasten the plate to the device were such that they were easily removed by the user. This is contrary to requirements in 10 CFR 34.20(a) which states that all devices in use meet the requirements of ANSI N432-1980.
ANSI N432, Section 5.1.2.1, requires that "[t]he exposure device shall have a lock which is not easily removabl9 by unauthorized personnel." To correct this situation, INC has modified the device design to secure the lock screws by placing a self-adhesive metal foil over the screws.
The foil and adhesive are such that the foil is difficult to remove and cannot be removed and replaced without showing signs of damage. The foil will serve to inhibit unauthorized personnel from accessing the screws, and to provide a means to alert the licensee to possible tampering of the lock. INC has indicated that it will contact all owners of potentially affected cameras, on record with it, to notify them of the retrofit, and to retrofit the cameras for them or to provide them with the foil covers and instructions on retrofitting the devices. Attachment 1 contains a copy of the retrofit letter.
All affected cameras should be retrofitted as soon as possible. Licensees should contact INC, or the State of California, to obtain retrofit kits or assistance with retrofit procedures, or to report that they have not received their kits. Affected cameras may be checked for completed retrofit 3 during any inspection.
This information notice requires no specific action nor written response. If you have any questions about the information in this nctice, please contact one of the technical contacts listed below or the appropriate regional office.

NO,: CA384D109S DATE: February 24,1997 PAGE: 2 of 12 DEVICE TYPE: Radiography Device DESCRIPTION:
The device consists of the following major parts:
?
(1)
A. depleted uranium casting embedding a titanium or zircalloy "S" tube. All contact points between uranium metal and the stainless steel are protected with 0.010" copper.
(2)
A stainless steel box 10-7/8" (length) x 4-1/4" (width) x 9-l/4" (height) and 0.125" thick with a handle heliarc welded on the top.
('3)
Source Tube Assembly - A flexible metallic hose consisting of one, two, or three 7-foot sections through which the Source is moved by the Drive Cable.
(4)
Control (Crank) Assembly - Consisting of two flexible Drive Cable liousings (25 foot each);
a IIand Crank assembly, provided with a Cable Reel or pistol Grip; and a special swivel connector (with tab) for attaching the Control Assembly to the Device.
The depleted uranium casting with the "S" tube is cased inside the stainless steel box. The space around the casting is filled with polyurethane foam The "S" tube is open to the outside through a hole in each end of the box. A stainless steel fitting is heliarc welded to the outlet end of the hole for attachment of the source tubc(s). A stainless steel lock body is heliarc welded to the opposite hole. The lock body contains a lock cylinder, a latching indicator plate, and a retainer to prevent removal of the source assembly. The retainer fitting is internally threaded to permit attachment of a remote drive assembly. The outlet fitting is provided with a shipping plug assembly which acts as an extra means to secure the source in the safe zone. The latching indicator plate prevents operation of the device in the lock mode, provides a visible indication when the device is in the operable mode and traps the source pigtail assembly in the safe zone. A manual reset of the indicator is required before the source can be moved out of the safe zone.

NCL: CA384D109S DATE: February 24,1997 PAGE: 3 of12 l
DEVICE TYPE: Radiography Device DESCRIPTION CONTINUED:
Failure to connect the Drive Cable to the Source Pigtail Assembly will prevent unlocking of the device. Verification of the connection must be performed (by retracting the Source Pigtail Assembly) before the Device can be unlocked. When the Control (Crank) Assembly is rotated in the " retract" mode, the indicator will " pop-up" to a safety latch position. This function sen*es the purpose of verification that the Drive Cable is connected to the Source Assembly and also indicates, visually, that the Device is unlocked, The safety latch must be depressed before the source can be exposed. When the Source Assembly is fully retracted into the Exposure Device, the latch will engage the Source Assembly. This may be observed by the " pop-up" indicator. Verifier.tica of this condition may be made by rotating the lland Crank in both directions. At this point, the Source Assembly will not crank out until the latch indicator is manually reset (depressed). The Device can be locked only when the Source (Pigtail) Assembly is in the safe position in the Device. The key cannot be removed except when the Device is in the locked condition. The Control (Crank)
Assembly can not be removed until the Device is locked and the key is removed. The special tab on the swivel connector prevents the disconnecting of the Control Assembly unless the key is removed.
The device weighs appmximately 52 pounds. The contained unmium casting weighs approximately 32 pounds.
Compatible source changer with the Exposure Device Model IR 100 is: Industrial Nuclear Model IR 50.
