UNITED STATESNUCLEAR REGULATORY COMMISSIONOFFICE OF NUCLEAR MATERIAL SAFETY AND SAFEGUARDSWASHINGTON, DC 20555June 18, 1997NRC INFORMATION NOTICE 97-35: RETROFIT TO INDUSTRIAL NUCLEAR COMPANY(INC) IR100 RADIOGRAPHY CAMERA TOCORRECT INCONSISTENCY IN 10 CFR PART 34COMPATIBILITY

Addressees

All industrial radiography licensees.PurnoseThe U.S. Nuclear Regulatory Commission (NRC) is issuing this information notice to makelicensees aware of a scenario where the Industrial Nuclear Company (INC) Model IR100Radiography Camera would not pass the horizontal shock test, as required by 10 CFRPart 34, and of a retrofit to the INC Model IR1 00 radiography camera, to correct thatproblem. It is expected that recipients will review the information for applicabilityto their licensed activities, and consider actions, as appropriate, to avoid problems.However, suggestions contained in this information notice are not NRC requirements;therefore, no specific action nor written response is required.Descrintion of CircumstancesRecently, NRC became aware of a scenario where the INC Model IR100 radiographycamera would not pass the horizontal shock test, as required by 10 CFR Part 34.20,"Performance Requirements for Radiography Equipment." INC and the State of Californiaevaluated the problem, and INC took action to correct the situation.DiscussionINC recently identified the "Safety Latch Plate" on the IR100 radiography camera as apotentially more "fragile area" (as specified in ANSI N432-1980, Paragraph 8.3.2) than thearea previously tested. It appeared that if the Safety Latch Plate were struck directly onthe front surface of the plate (with the source in the safe locked position), the plate couldbe deformed and deemed inoperable. It also appeared that the plate might be susceptibleto damage if struck from the top and side. To ensure that this type of potential damagewas not possible, a bumper that would prevent deformation was welded to the back of theSafety Latch Plate, and the outer top edge of the plate was angled at a 45 to 50 degreeangle to a depth of approximately 3 mm (0.12 inch). The modified device was tested toensure compliance with ANSI N432-1980, paragraph 8.2.When the source is in the locked, stored position, there appeared to be no significantsafety issues, since bending of the Safety Latch Plate prevents source crank out.However, the State of California has stated that if the source was in the exposed positionat the time of impact, the source would not be able to be returned to the shielded andsecured position.e2O344 , P JD h K '/ IN 97-35June 18, 1997 INC has indicated that it will contact all owners of potentially affected-cameras, on recordwith it, to notify them of the retrofit. INC has recommended that users return the camerasto INC for retrofits. INC has indicated that it can also send retrofit kits and instructions tousers that wish to perform their own retrofits. Attachment 1 contains a copy of the retro-fit kit letter and replacement instructions. The retrofit can be differentiated from theoriginal design by verifying that the top part of the plate has a bumper, that is welded onthe backside of the Safety Latch Plate and which fills a good portion of the space betweenthe Safety Latch Plate and the body of the projector.To allow licensees sufficient opportunity to request and install the retrofit, units notcontaining the retrofit will continue to be approved for use through December 31, 1997.Effective January 1, 1998, units not containing the retrofit will no longer be approvedfor use. Affected cameras may be checked for completed retrofit during any inspection.Cameras with the retrofit will be deemed to meet the requirements of 10 CFR Part 34.All affected cameras should be retrofitted as soon as possible. Licensees should contactINC, or the State of California, to obtain retrofit kits or assistance with retrofit pro-cedures, or to report that they have not received their kit. Affected cameras may bechecked for completed retrofits during any inspection.This information notice does not require any specific action or written response. If youhave any questions about the information in this notice, please contact one of thetechnical contacts listed below or the appropriate regional office.signed byDonald A.
