UNITED STATESNUCLEAR REGULATORY COMMISSIONOFFICE OF NUCLEAR MATERIAL SAFETY AND SAFEGUARDSWASHINGTON, DC 20555December 12, 1997NRC INFORMATION NOTICE 97-87: SECOND RETROFIT TO INDUSTRIAL NUCLEARCOMPANY IRiOO RADIOGRAPHY CAMERA, TOCORRECT INCONSISTENCY IN 10 CFR PART 34COMPATIBILITY

Addressees

All industrial radiography licensees.PuMroseThe U.S. Nuclear Regulatory Commission (NRC) is issuing this information notice to makelicensees aware of a retrofit to the lock of the Industrial Nuclear Company (INC) Model IR100Radiography Camera, to correct an inconsistency in 10 CFR Part 34 compatibility. It isexpected that recipients will review the information for applicability to their licensed activities,and consider actions, as appropriate, to avoid problems. However, suggestions contained inthis information notice are not NRC requirements; therefore, no specific action nor writtenresponse is required.

Description 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 notpass the horizontal shock test, as required by 10 CFR 34.20, resulted in the equipment notmeeting 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 thesituation.DiscusionThe "Safety Latch Plate" on the IR100 radiography camera has a potentially more "fragile areas(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 (withthe source in the safe locked position), the plate could be deformed and deemed inoperable. Italso appeared that the plate might be susceptible to damage if struck from the top and side. Toensure that this type of potential damage was not possible, a bumper that would prevent9¢ ho ROTOR- q1og 0 rlal_ asd 64thaf %9120901 1i'.1 b ([12 -f /,c IN 97-87December 12,1997 deformation was welded to the back of the Safety Latch Plate, and the outer top edge of the platewas angled at a 45-to-50-degree angle, to a depth of approximately 3 mm (0.12 inch). Themodified device was tested to ensure compliance with ANSI N432-1980, paragraph 8.2.In the Safety Latch plate retrofit to the IR1 00, the Allen screws used to fasten the plate to thedevice were such that they were easily removed by the user. This is contrary to requirements in10 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 0(t]he exposure device shall have a lock which is noteasily removable by unauthorized personnel." To correct this situation, INC has modified thedevice 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 andreplaced without showing signs of damage. The foil will serve to inhibit unauthorized personnelfrom accessing the screws, and to provide a means to alert the licensee to possible tamperinq ofthe lock. INC has indicated that it will contact all owners of potentially affected cameras, onrecord with it, to notify them of the retrofit, and to retrofit the cameras for them or to provide themwith the foil covers and instructions on retrofitting the devices. Attachment I contains a copy ofthe retrofit letter.All affected cameras should be retrofitted as soon as possible. Licensees should contact INC, orthe State of California, to obtain retrofit kits or assistance with retrofit procedures, or to report thatthey have not received their kits. Affected cameras may be checked for completed retrofitsduring any inspection.This information notice requires no specific action nor written response. If you have anyquestions about the information in this notice, please contact one of the technical contacts listedbelow or the appropriate regional office.\.9Donald A.
