Jack Taylor Groton, Connecticut 06349 Gentlemen:
The enclosed Nuclear Regulatory Connission (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 more of these gauges which are manufactured by Kay-Ray, Incorporated.
These gauges contain radioactive material regulated by the NRC.
The possession and use of the radioactive material contained in the gauges is governed by either a specific NRC 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 regulation from the gauge vendor when you received the gauges.
Should you have any questions regarding this Bulletin or the actions required of you, please' contact this office.
Sincerely, Boyce H. Grier Director

20555 IE Bulletin No. 78-13 Date:
October 27, 1978 Page 1 of 2 FAILURE IN SOURCE HEADS OF KAY-RAY, INC., GAUGES MODELS 7050, 70508, 7051, 7051B, 7060, 70608, 7061, AND 7061B f
Description of Circumstances:
The U.S. Nuclear Regulatory Commission (NRC) has received information that cn 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 radioactive 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, exposing 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 proximity to a gauge where the lead dome had separated from the box.
i In order to correct this potential radiation hazard, Kay-Ray has de-veloped 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 tele-phone number, complete the other actions according to the instruc-tions, and sign the preaddressed form and return it to the NRC after completing all the required actions.
TE Bulletin No. 78-13 Date:
October 27, 1978 Page 2 of 2 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 enclosed form, and (a) if you possessed the gauge under a general license of 10 CFR 31.5 include with the form 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 provide the name and address of the persons or organizations to whom 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, 70508, 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 following actions:
(a) contact Kay-Ray immediately at (312) 259-9244 and inform them, 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 after receiving the support bracket (s) from Kay-Ray, install a support bracket on each Kay-Ray gauge model (identified in item 3 above) in your possession.
5.
Within twelve (12) days after receiving the support bracket (s) from Kay-Ray, report the completion of the above actions to this office.
The report should be submitted by completing and returning the enclosed preprinted, preaddressed form to the NRC.
In addition to the above specific actions, we reccmmend that you read and become thoroughly familiar with the conditions of either the specific NRC license or the general license of 10 CFR 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 der a blanket clearance specifically for identified generic problems.

- CABLE;KAYRAY J6ne 30, 1978 Dear Sir In follow-up to our letter of March 6, 1978, (copy attached) we wish to advise you of additional action taken by Kay-Ray concern-ing the referenced source head structural problem.
These rare failures have not resulted in any definable radiation overexposure to plant personnel, but we believe that every reasonable precaution should be undertaken.
Kay-Ray has developed a support bracket that can be simply added by your maintenance people to your source heads which will prevent the dome from separating from the head if a weld fracture should occur.
This bracket substantially reduces the possibility of a radiation hazard developing by keeping the lead dome attached to the source head independently of the welding.
The attached drawing illustrates'the brackets that have been designed to be compatible with the dif ferent variations of source heads in this family.
The bracket can be easily added to your source head in less than fifteen minutes, while the head is in normal operation.
No process downtime is required.
To encourage use of this safety feature, Kay-Ray will supply this bracket free of charge at your request.
Please fill out the attach-s ed card to confirm the specific source heads presently installed at your facility so that the proper bracket and instructions can be.sent.
In closing, we would like to emphasize the importance of this safety precaution.
We hope to hear from your shortly.
Sincerely, KAY-RAY, INC.
