PION SCATTERING FROM A POLARIZED TARGET

Description: This report describes the use of a target containing polarized protons in a particle-scattering experiment. Positive pions of 246-MeV kinetic energy were scattered from the polarized protons. The parameter P that was measured is equivalent to that determined by analyzing the recoil-proton polarization in scattering from an unpolarized target. It has been measured to a higher accuracy than heretofore achieved in pion-proton scattering, at an energy and at angles inconvenient for double-scatterin… more

Nuclear safety experience -- Hanford production reactors

Description: Reactor operations at Hanford are to be conducted in the future under a new contract clause on nuclear health and safety, which sets up a form of AEC control somewhat akin to the licensing and regulatory function of the Commission with respect to commercial nuclear plants. As this transition in functional responsibilities approaches, it seems appropriate to review the record of more than 100 reactor-years of General Electric operation at Hanford, and to give an accounting of stewardship in rega… more

Production test IP-614-A: Irradiation of thorium target elements

Description: Limited irradiations of thorium target elements have been conducted at HAPO during the past ten years but large-scale irradiations have not been attempted. An obstacle encountered in thorium irradiation programs has been the formation of U-232, which is undesirable because of intense gamma radiation. Further study of the problem indicates that by employing certain restrictions during irradiation of the thorium a relatively ``clean``, free of U-232,,product U-233 may be obtained. The objectives … more

K and N reactor capabilities

Description: This report contains data on the relative capabilities of the K and N plants to produce various isotopes. The data are ``direct and quantitative`` in cases where production plans for the various isotopes have been studied. For isotope studies not completed production capabilities are, of necessity, discussed from only a qualitative standpoint.

Possible consequences of operation with KIVN fuel elements in K Zircaloy process tubes

Description: From considerations of the results of experimental simulations of non-axial placement of fuel elements in process tubes and in-reactor experience, it is concluded that the ultimate outcome of a charging error which results in operation with one or more unsupported fuel elements in a K Zircaloy-2 process tube would be multiple fuel failure and failure of the process tube. The outcome of the accident is determined by the speed with which the fuel failure is detected and the reactor is shut down. … more

Production Test IP-601-D: Evaluation of crud-forming characteristics of KER loop coolant containing NH{sub 4}OH for pH control

Description: The objective of production test detailed in this report was to characterize the effects of NH{sub 4}OH as a pH control agent in a recirculating, high temperature and pressure water system having NPR characteristics. Of particular interest is the crud forming and decomposition characteristics of NH{sub 4}OH at potential NPR conditions.

Interim report IV, production test IP-549-A half-plant low alum feed water treatment at F Reactor

Description: A half-plant low alum water treatment test began at F Reactor on January 16, 1963. The test, which had been prompted by the analysis of ledge corrosion attack on fuel elements, will demonstrate whether or not high alum feed is responsible for increasing the frequency of ledge and groove corrosion attack on fuel element surfaces. The effect will be evaluated by comparing visual examination results obtained from normal production fuel irradiated in process water treated with two different alum fe… more

Technical criteria and bases reactor gas system: 100-K

Description: With an increased water plant capacity, the installation of zirconium process tubes and the use of self-supported fuel elements, the power level capability of the K Reactors exceeds the current administrative limit. Exploitation of this capability, if approved, will almost certainly bring about higher graphite temperatures. Because of a continuing concern for graphite oxidation, and because the rate of oxidation increases with increasing graphite temperature, upgrading of the existing K-Reactor… more

Uniformly Reactive Uranium Dioxide from a Single Oxidation-Reduction Cycle

Description: Abstract: By use of a modified thermobalance and reactor as the primary experimental tool for sample preparation and evaluation, a process has been developed by which parent uranium feed materials of a widely variable reactivity and composition may be converted to a uniformly reactive uranium dioxide.

A Method for Performing a Human-Factors Reliability Analysis

Description: Foreword: There has been relatively little work reported on deriving quantitative estimates of the degradation to a man-machine system resulting from human errors. One approach, used in the Reliability Department of Sandia Corporation, is presented here as an example of how such estimating can be done.

Reactivation of shutdown reactor plants

Description: This report presents preliminary planning information which supplements two prior special reactor study reports. It is the purpose of this study to consider expedited reactivation of reactors and to evaluate the factors which are likely to be controlling to, or have a major influence on the time required to reactivate one or more of Hanford`s six small reactors after an assumed period in the lay-away status. It is assumed that the methods to be applied in preserving and protecting inactive equi… more

Technical studies supporting IPD disaster planning

Description: A study was undertaken of means for rendering the plant less vulnerable to self-destruction with radioactive contamination spread. It was concluded that the only course of action was to totally discharge the reactors and provide water cooling flow by gravity to the reactor storage basins. This report reviews the technical considerations involved in determining the feasibility of the course of action with emphasis on assuring basin integrity.

Unusual incident report No. 25 crossheader damage

Description: The DR Reactor was shut down on July 10, 1963, for a scheduled charge-discharge outage. During the charge-discharge operation on July 11, 1963, the front work platform was being lowered to a new location for charging when the far side charging machine mounting rail came in contact with the 2 1/2 inch drain valve stem on front crossheader No. 25. Before the platform travel could be stopped, the drain valve and the related 2 1/2 inch piping was twisted down transmitting sufficient force to the cr… more

KER-2 operating report test K-2-16 PT IP-544-A

Description: The purpose of this test was to evaluate the uranium swelling and distortion of coextruded Zr-2 jacketed tubular fuel elements operating at N Reactor environmental conditions but with considerably higher uranium temperatures than those occurring in normal N Reactor fuel. The test is expected to provide information useful in the design and analysis of single tube fuel elements for use in N Reactor.

SIZCAN: A Fortran code to aid in sizing cylindrical or annular fission product containers

Description: The problem of designing storage containers for heat-generating fission products or radioactive wastes is complicated by the interdependence of a number of variables. The permissible maximum surface temperatures and internal temperature; the concentration, age, and type of isotope; the thermal conductivity of the materials, the ambient temperatures, the configuration (annular or cylindrical) of the container; and the mechanism of heat removal, all affect the design of the container 4-n that the… more
