JAN P0 ?c7e SGPS:RRR 70-687 Union Carbide Corporation Sterling Forest Research Center ATTN: Mr. Marcus H. Voth Manager, Nuclear Operations P. O. Box 324 Tuxedo, New York 10987 Gentlemen:
Reference is made to your letter of November 10, 1978 regarding a request for exemption from 10 CFR 73.50 for certain special nuclear material under License No. SNM-639. We have determined that an exemption to the requirements of 10 CFR 73.50 as pertains to irradiated target material is authorized by law, will not endanger life or property or the common defense and security, and is other-t wise in the public interest.
Accordingly, we are hereby amending Materials and Plant Protection Amendment MPP-3 to your License No. SNM-639 by adding Section 9 as ist forth in the enclosure to this letter, effective immediately.
Sincerely, d-A Robert F. Burnett, Director Civision of Safeguards

9.2 The licensee is not required to include uranium-235 contained in irradiated target material in calculations of the 5~,000 gram thresh-old for application of 10 CFR 73.50 provided that the hot cells are protected within a protected area so that irradiated target material located there is afforded the same protection measures as given to irradiated fuel elements in the reactor building under the licensee's approved reactor security plan, and (a) locks and alarms which annunciate upon unauthorized use when the area is unoccupied are provided to either the hot cell manipula-tors or hot cell doors (b) any irradiated target material located in the transfer channel or reactor pool is in a container which has an external radia-tion dose rate of 100 rem at 3 feet from its surfaces without intervening shielding and equipment for handling such containers is provided with locks and alarms which annunciate upon un-authorized use when the area is unoccupied.
