Anticipated heat generation rate of MGCR-III fuel element as a function of enrichment

Description: The DR-1 Loop, located in the C test hole of the DR Reactor, provides a high temperature, recirculating gas-cooled facility for the irradiation of experimental fuel elements. The loop is being utilized currently by General Atomic, a Division of General Dynamics, to evaluate fuel elements in support of their work on the Maritime Gas-Cooled Reactor Program, a program which is directed at the development of a ship propulsion unit consisting of a gas-cooled reactor driving a closed cycle gas turbin… more

The Application of an Operational Reactivity Accounting System Based on One-Group Diffusion Theory

Description: HW-70780, {open_quotes}An Operational Reactivity Accounting System Based on One-Group Diffusion Theory{close_quotes} describes a reactivity accounting system which is an improvement over the present {open_quotes}flux-squared weighting{close_quotes} system. Several changes and additions have been made which will simplify and increase the accuracy of the system described in the parent document. The changes occur primarily in the application of the system and are compatible with diffusion theory a… more

Calculations of the surface heat flux and fuel temperatures for PRTR MK-I PuO{sub 2}-UO{sub 2} fuel element with segregated PuO{sub 2}

Description: The methods used to fabricate the present loading of PuO{sub 2}-UO{sub 2} fuel elements for the Plutonium Recycle Test Reactor have resulted in alternating bands of high and low PuO{sub 2} concentration along each rod of the 19-rod elements. These bands are repeated every 1/2 or 1 inch along the length of the rod, depending on whether the loading of the oxides was done in 160 or 80 increments. This non-uniform distribution of PuO{sub 2} results in alternate regions of high and low heat generati… more

Capillary liquid evaporation from wick covered plates: theory

Description: Differential equations and associated parameters are derived for heat transfer to a thin liquid-saturated wick, as in the evaporator section of a ''heat pipe.'' Prescribed are a numerical method of solution and a procedure for experimental measurements of heat transfer in the flat plate model. This effort is a part of the Project CLEER program which is currently sponsored by the Mechanical Engineering Department research account.

Comment on Temperature-Pressure Equilibrium Between Dispersed and Continuous Phases of a Material

Description: This memo calls attention to the fact that the relationship between equilibrium temperature and the pressures in two phases of a material is {Delta}sdT = {Delta}(vdP) , and not, as now routinely assumed by bubble investigators, the Clausius-Clapeyron equation {Delta}sdT = {Delta}vdP . If one phase is discontinuous (subscript "d") and consists of spheres of radius r in a continuous phase (subscript "c") whose pressure is held constant, then the equilibrium temperature will be… more

Contraction of graphite: A comparison of laboratory and production reactor data, Part 2, KE and KW Reactors

Description: Part 1 of this two-part report presented a comparison of the irradiation-induced contraction rates obtained on standard-size graphite samples and the apparent moderator contraction rates of H, DR and C Reactors. The distortion trends of the top center of the graphite stacks, from which the apparent moderator contraction rates were derived, were presented as a function of cumulative power generation since start-up for each of the six older Hanford reactors. Since KE and KW Reactors are of identi… more

Conversion ratio tables

Description: This manual provides a list of the quantities of plutonium and plutonium isotope formation. Other isotopes whose concentrations are important and included in this report are U-236 buildup, U-235 burnout, U burnout, Np-237 build-up, GVR (the Gas Volume Ratio) in coproduct target elements and equivalent gram of plutonium. These conversion tables have been calculated on the IBM 7090 digital computer using a program entitled ``FLEX-3.`` The results of the computer solutions have not been normalized… more

Cover sheet for a Hanford Historial Document for public availability

Description: The following criteria defines the objectives, bases and functional requirements that shall govern the preparation of the final design for the zirconium process tube installation program at the 100-K Areas. As a result of this program, reduced operating costs and increased production can be achieved. The present central zone aluminum tubes in the 100-K Reactors require replacement every to to three years to prevent excessive failures resulting from the thinning of the tube walls by corrosion.

Distribution of time between unscheduled outages

Description: A study is in progress in which reactor operations will be simulated on the computer, the primary purpose being to evaluate the costs associated with various administrative alternatives which may be followed in conducting the overall operation, in addition to defining how operational costs are affected by such things as changes in fuel quality. The problem is complicated by the fact that the operation of the reactors is largely affected by random occurrences; no one can predict exactly when a t… more

Effect of increased nickel content in canning baths

Description: Canning bath Al-Si, supplied from offsite vendors and reclaimed lathe turnings in the 313 building, is used in the production of I & E fuel elements. A study was made of the effect of increasing the Ni content to over 0.5% in the canning baths, in order that all of the X-8001 scrap could be reclaimed. Effect on bond quality, weld integrity, and canning bath operation was studied. Based on adverse weld quality, slight loss in reactivity, and potential for furnace channel plugging, it is recommen… more

Fabrication of enriched hot die sized diffusion bonded fuel elements for Production Test IP-616-A

Description: Hot die sizing (HDS) is a process being investigated to replace the existing AlSi brazing process. Hot die sizing consists of sizing a nickel-plated core and aluminum can assembly with cold dies to produce a diffusion bonded aluminum clad fuel element. Upon completion of fabrication of the first natural uranium hot die sized fuel elements for production test IP-546-A, the next step in evaluation of the process was to assemble enriched fuel for further irradiation testing. This report summarizes… more

Helios pulsed nuclear propulsion concept

Description: A Helios-propelled vehicle would make use of a containment vessel--perhaps 30 feet in diameter--in which small nuclear explosive charges would be placed, together with a few hundred pounds of hydrogen. Firing of a charge would result in bringing the mixture of charge residue and hydrogen to a high temperature--say 5000 or 6000/sup 0/K--and subsequent release through a nozzle would provide propulsive thrust. This process would be repeated several thousand times, at intervals likely to be 10 seco… more

Laboratory determination of normal operating flow rates with enlarged outlet fittings -- BDF reactors

Description: Experiments have been conducted in the Hydraulics Laboratory, at the request of IPD`s Mechanical Development-A Operation, to determine the energy losses of various enlarged outlet fitting combinations. These experiments were conducted an steady state runs and allow the determination of the normal operating point (flow rate) of a reactor process channel under selected conditions of front header pressure and fuel charge. No attempt is made to make a mechanical or economic evaluation of the partic… more
