RADIOACTIVE CESIUM SOURCE PRODUCT MATERIAL FOR SALE Lockheed Martin Energy Systems, Inc., Government Sales Office, P.O. Box 2003, Hwy. 58, Portal 4, Oak Ridge, Tennessee 37831-7400. Cesium source material for sale. Due June 4, 1996. Point of Contact: J. D. Huddleston, Sales Administrator, (423) 576-1451; Fax (423) 576-2321. Lockheed Martin Energy Systems, Inc., representing Lockheed Martin Research Corporation and acting for and on behalf of the U.S. Government as represented by the U.S. Department of Energy under its Prime Contract Number DE-AC05-84OR21400 is offering for sale U.S. Government-owned surplus cesium radioactive by-product material which has no defined nor planned future use. This material was either fabricated at the Oak Ridge National Laboratory (ORNL) or purchased from Gamma Industries in 1977. By Nuclear Regulatory Commission (NRC) definition, this material is ``by-product material'' in the form of ``sealed sources'' (10 CFR 30.4). The material consists of four weld-sealed stainless steel capsules, approximately 0.2 to 0.6 in. in diameter and 0.6 to 2 in. long, presently located at the irradiation laboratory. The four capsules contain cesium sources (about 0.65, 11.3, 47.9, and 110 Ci, respectively). The documentation for the capsules is limited since they are about 30 years old. As far as is known, the three capsules with the higher activity were fabricated at ORNL from U.S. Government materials; the capsules with the smallest activity was purchased from Gamma Industries in 1977. From an engineering specification, it is believed that each ORNL source has been fabricated as a double-encapsulated, weld-sealed stainless steel capsule. The specification indicates that the chemical and physical form of the cesium is cesium chloride powder. The smallest source was custom designed by Gamma Industries to replace an existing ORNL source with the same physical dimensions, but no data about this source is currently available. The capsules have not been leak checked on a periodic basis; however, no evidence of leakage has been detected. When the capsules are removed from the irradiation laboratory, the capsules will be determined by visual inspection and smear counting to be uncorroded and physically intact before they are packaged for shipment. To express an interest in bidding on this material or to receive a copy of the invitation to bid, contact J.D. Huddleston, (423) 576-1451. Bids close June 4, 1996, 2:30 p.m., local time. (136)
