Certificate of Compliance No. USil/9127/Blu)
Cobalt 60 EHposure Devices (00mmatron) 4
Dear Mr. Withee,
Industrial Nuclear Company has received reliable information that the fimersham Corporation will abandon the Certificate of Compliance for Package identification Number USfl/9127/B(U) by January 10, 1996.
Rfter January 10, 1996, the eHposure devices Will no longer meet the requirements of 10CfR Part 34.20 (automaticalig securing the source assembig). Information has it that Amersham will not try to upgrade (retrofit) the devices with a new locking system to meet compliance of 10CfR Part 34. There are hundreds of.these devices presently in use throughout the industry. Industrial Nuclear Company sees a need to upgrade these devices to meet the compliance of 10CFR Part 34.20. INC would like to obtain a modified Certificate of Compliance onder the present registered device testing. The enig modification would be the locking system. The new lock system would not change its weight, its t
operation (eHcept automatically secure the source assembig), the source pigtail, or the device's configuration.
It is proposed that the locking system presently approved for the 18-100 EHposure Device (Iridium 192) be used.
As indicated by the attached sketch, the-modification is simple. We will attach a plate to the lock and bolt it in the original bolt holes (inside the lock protected area of the device).
We would like your cooperation and assistance in what INC can do to assist the industry in continuing to use these devices after January 10, 1996. Since the device (Gammatron) and the locking system (1H-100) have been tested and approved, we feel the retesting would not be CA OF FICE:

I ii W INDUSTRIAL NUCLEAR CO, INC necessary, if retesting should be required, then it would be too costly to modify the devices and they would no longer be authorized for use under 10Effl Part 34.
This would be very costly to the industry.
Licensee's would have to buy new Cobalt 60 Devices from a single manufacturer who has increased prices tremendously in the past 3 years.
Hopefully, our concerns to save these devices will allow U.S.N.fl.C to assist INC in obtaining a solution.
Should you have any additional questions, concerns or comments, please do not hesitate to contact the undersigned.
Sincerely, E. W. Iluddles ton President 2
