Criticality of heterogeneous lattices of Experimental Beryllium Oxide Reactor fuel pins in water and in aqueous solutions containing boron and uranyl nitrate

Description: The fuel intended for the Experimental Beryllium Oxide Reactor was made available for a series of critical experiments at the Oak Ridge Critical Experiments Facility. The fuel pins consisted of compressed ceramic pellets contained in Hastelloy X-280 tubes. The pellets were a homogeneous mixture of U(62.4)O/sub 2/ and BeO. The data generated are applicable to support the establishment of specifications for the chemical recovery of uranium in a process in which boron as a soluble neutron absorber… more

Critical mass studies. Part XII. Rover reactor fuel elements

Description: Declassified 29 Aug 1973. Critical experiments were performed with fuel elements for the Project Rover KIWI-B-2A reactor to determine nuclearly safe conditions for their production, storage, and transportation. Each element is a 0.746-in.-dia and 50.5-in.-long uranium carbidegraphite cylinder containing seven uniformly spaced longitudinal holes. The uranium concentration is 400 mg/cm/sup 3/, of which 93.15% is /sup 235/U, yielding a C: /sup 235/U atomic ratio of about 90. Throughout the experim… more

Energy Per Fission and Power of the Bulk Shielding Reactor

Description: Due to some lack of knowledge of the energy per fission, there has been some uncertainty over the absolute power of the Bulk Shielding Reactor. This report analyzes measurements to state the absolute power of the BSR within a few percent.

Bibliography of ORNL-BSF Reports Pertinent to Swimming Pool Type Reactor Design (Revised)

Description: Much of the shielding work carried out with the Bulk Shielding Reactor (BSR) has yielded data of particular interest for the design of swimming pool type reactors, However, it is often difficult for a reactor designer to locate such data since it may be recorded in a report primarily concerned with shielding problems. Therefore, this memorandum presents a bibliography of reports from the Bulk Shielding Facility arranged according to the application of data to the various aspects of reactor desi… more
