A computer program is being developed for the solution of general system flow problems. As a complement to this program, a summary of the process system has been prepared. This assembles information from a number of different reports, drawings and technical notebooks into one place for easy use and reference. It is expected that the information contained in this report will be of use in safety and design studies of these process systems. This report presents current values of the reactor flow characteristics and the primary pumping system characteristics. It also presents the process piping system and the basis for a computing program for calculating system pressure drops.

During the post-irradiation examination of borides it was discovered that the samples which had been irradiated as powders had sintered into firmly bonded bodies. This radiation sintering occurred at temperatures hundreds of degrees below that required to produce similar interparticle bonding by the application of heat alone. , This report discusses the results of the postirradiation examination of some of these borides which were irradiated as powders and compares the results of our observations with the reports of simiiar radiation sintering occurring in other materials.

Progress Development of a high temperature, vaporfilled thermionic converter for application with a nuclear reactor for space-vehicle electrical power generation is reported. Problems associated with the design and opera tion of a thermionic converter employing a UC-ZrC emitter, a cesium plasma for space charge neutralization, and a high-temperature collector are described. Emitter fabrication techniques are also described. A test cell employing a cylindrical UC-ZrC emitter, which was pressure bonded to a tantalum sleeve, and a low- temperature copper collector, was fabricated and operated for 400 hours to provide experimental data. The emitter was operated at temperatures of the order of 2000 deg C while the collector temperature was maintained at 200 to 300 deg C. A conceptual design for a thermionic power reactor incorporating the thermionic converter under development is also studied. It was concluded that a thermionic fuel element would be about 20 inches long and 0.68 inch in diameter and would incorporate 1O thermionic cells. The load voltage per fuel element would be about 14.5 volts and two elements would be connected in parallel (electrically) to provide an output of 29 volts. The over-all design would provide an electrical power level of approximately one megawatt. (auth)

Ten columns of ripe uranium were discharged and recharged from KE Reactor during operation (first large scale refueling test with Operational Fueling Facility gear). For the last year, many tests were performed in preparation for the ten tube discharge. Objectives of the production test have been met. The system was proved to be feasible; no reactor control problems were encountered by refueling during operation.
