Fast Neutron Fluxes in Hanford Reactors

Description: The results of a multi-group, diffusion type code computation for the fast neutron flux distribution in C, K, and N reactors are presented. Relative Ni activations in conjunction with the calculated neutron spectra are used to obtain values for the integrated fast flux per MWD/AT for C and K reactors. The relative, theoretical, integrated fast flux values at the same adjacent fuel powers in C, K, and N reactors in the mid-plane of the filler layers are: (1) C = 1.0; (2) K = 1.3; and (3) N = 2.6… more

Summary of KER-1 operation, February 15, 1958--March 1, 1960

Description: Recent borescoping of the KER-1 tube revealed several scratches, pits, and gall marks on the internal wall of the tube. These deformations could limit the operating temperature and pressure of KER-1. This report is a summary of operating history and is compiles to assist in determining what contributed to the condition of the tube.

In-reactor rupture testing of Zircaloy-2 clad seven-rod cluster fuel elements: Interim report

Description: The high pressure loop installed in the 3X3 reflector position of the ETR and the associated instrumentation to detect and study failure mechanisms handled the rupture tests without difficulty. Failure of the elements was initiated by shearing off a projection on the fuel elements. The first test of the series used previously unirradiated seven-rod clusters. After the projection was sheared off the fuel elements were operated for seven hours with no failure. Failure is defined as having occurre… more

Production Test IP-358-AC: Replacement of carbon dioxide with nitrogen as a constituent of the K reactor atmosphere

Description: Compensation for the positive long-term reactivity transient associated with Hanford reactor may be accomplished in two ways: The addition of a poisonous material (rods, splines, etc.) to the reactor, or cooling the moderator by changing the gas composition. The objective of this study is to investigate the reactivity and temperature effects and the associated operating problems if any, resulting from the use of nitrogen instead of carbon dioxide as a constituent of the reactor atmosphere.

Technical bases for C-pile overbore test

Description: The production gains and economic evaluation of overboring has been extensively treated. In this document, the justification for a trial attempt at overboring C-Reactor was given. The overboring test, covered by two production tests (one or overboring and one for fuel irradiation), requires the integration of efforts of Equipment Development, Process and Reactor Development, Process Technology, Manufacturing, and the Fuels Preparation Department. In view of this, it appears prudent to collect i… more

Heat Transfer Experiments of the Title II Fuel Assembly for the Experimental Gas Cooled Reactor. Section IV of the Fuel Assembly Heat Transfer and Channel Pressure Drop Experiment of the EGCR Research and Development Program. Report RD-0010

Description: ABS>Experimental heat transfer data and analysis are reported for the Title II fuel assembly design modifications and refinements. Three distinct mid- length spacer designs are described. All tests are conducted with a 3,000-in. M fuel assembly sleeve and with the six outer tubes (of the seven tube cluster) located on a 2.000-in. BC. The dath are presented as heat transfer correlations and as comparisons of the heat transfer test results of one design with the results obtained from the other tw… more
