'CENTRXC FILES OCT 2 7.R8 Creater Cincinnati ATTN: Chief Instrumentation Engineer c/o R. H. Hetzcar and Son.,
Incorporated 400 Station Avenue Arlington Heights Cincinnati, Ohio 45215 Centlemen:
The enclosed Nuclear Regulatory Cocusission (NRC) IE Bulletin No. 78-13 requires action by you with respect to certain gauging devices in your possession. Records show that you have received one or siore of these gauges which are manufactured by Kay-Ray, Incorporated. These gauges contain radioactive material regulated by the NEC. The possession and use of the radioactive material contained in the gauges is governed by either a specific l'RC license issued to you or under the general license provisions of NRC regulation 10 CFR Part 31, Section 31.5.
A copy of 10 CFR 31.5 is provided for your information.
If you possess gauges under a general license, you should have received a copy of this regula-tion from the gauge vendor when you received the gauges.
Should you have any questions rerarding this Lulletin or the actions required of you, please contact this office.
Sincerely, James C. Keppler Director

i U.S. NUCLEAR REGULATORY COMMISSION OFFICE OF INSPECTION AND ENFORCEMENT REGION III October 27, 1978 IE Bulletin No. 78-13 FAILURE IN SOURCE HEADS OF KAY-RAY, INC., GAUGES MODELS 7050, 7050B, 7051, 7051B, 7060, 7060B, 7061, AND 7061B Description of Circumstances:
The U.S. Nuclear Regulatory Commission (NRC) has received information that on three occasions in the past year fractures have occurred at the weld between the dome and the box of source heads used in the subject gauges manufactured by Kay-Ray, Inc. These gauges contain radioactive material regulated by the NRC. The possession and use of the radio-active material in the gauges is governed by either a specific NRC license or under the general license provisions of NRC regulation 10 CFR 31, Section 31.5.
A copy of 10 CFR 31.5 is enclosed.
These incidents of weld fractures in the gauges have caused the dome to separate from the box, arposing the 500 millicurie cesium-137 sealed source. In one case, the radioactive source itself fell loose from the dome and was completely exposed. ' The separation of the dome from the box could result in a radiation overexposure if an individual actually handled the radioactive source or worked in close proxicity to a gauge where the lead dome had separated from the box.
In order to correct this potential radiation hazard, Kay-Ray has developed a support bracket which they will supply free of charge to prevent the dome separation if a fracture does occur. In a June 30, 1978 letter (copy enclosed) Kay-Ray advised you of the availability of the support bracket and requested you to return a card confirming the specific source heads in your possession. A number of companies have not returned a card to Kay-Ray, Inc.
In order to assure correction of this potential hazard, you should complete the following actions.
Actions to be taken by you as a licensee of the NRC:
1.
On the enclosed form, enter your company's name, address and telephone number, complete the other actions according to the instructions, and sagn the preaddressed form and return it to the NRC after completing all the required actions.
2-October 27, 1978 IE Bulletin No. 78-13 If you have transferred or otherwise disposed of any Kay-Ray gauges, take the action in item number 2, following:
2'.
Complete item 1 of the encicsed form, and (a) if you possessed the gauge under a general license of 10 CFR 31.5 include with the for=
a statement of how you have complied, or information which does comply, with the requirements of 10 CFR 31.5(c)(8) or (9) and pro-vide the na e and address of the persons or organizations to who:
the gauge was transferred, or (b) if you possessed the gauge under a specific license include with the form a statement of how you complied with the requirements of 10 CFR 30.41 and provide the name and address of the persons or organizations to whom the gauge was transferred.
If you have any of the specified Kay-Ray gauges in your possession, take the actions in item numbers 3 through 5. following:
3.
Within two (2) days of receipt of this Bulletin, visually inspect the source head on models 7050, 70505, 7051, 7051B, 7060, 7060B, 7061, and 7061B of Kay-Ray gauges in your possession for evidence of weld cracks between the dome and box. If cracks are found, take the fo13eving actions:
(a) contact Kay-Ray tenediately at (312) 259-9244 and inform the=, and (b) file a report with this office as required by 10 CFR 31.5(a)(5).
(A copy of 10 CFR 31.5 is enclosed.)
4.
Within ten (10) days af ter receiving the support bracket (s) from Kay-Ray, install a support bracket on each Kay-Ray gauge model (identified in itec 3 above) in your possession.
5.
Within twelve (12) days af ter receiving the support bracket (s) from Kay-Ray, report the conpletion of the above actions to this office.
The report should be sub=itted by completing and returning the enclosed preprinted, preaddressed form to the NRC.
In addition to the above specific actions, we reco= mend that you read and beco=e thoroughly f amiliar with the conditions of either the specific NRC license or the general license of 10 Crk 31.5 whichever authorizes your use and possession of the gauge devices.
Approved by GAO, B180225 (R0072); clearance expires 7-31-80. Approval was given unde.r a blanket clearance specifically for identified generic Problems.
