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

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

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

IPD reactor training text, declassified supplement: Chapter 2, Design and construction of the Hanford production reactors

Description: Purpose of this chapter is to provide an overview of reactor construction and an understanding of important design considerations: how it is built, why it was built that way, what it is supposed to do, what the nuclear safety considerations are, and what one needs to know about its design/construction to properly operate it.

Operating limits, Hanford Production Reactors. Revision 3

Description: These operating limits are applicable to eight operating production reactors, B, C, D, DR, F, H, KE, and KW. Subjects covered are: operating parameter limitations; reactivity limitations; control and safety systems; reactor fuel loadings; coolant requirements with irradiated fuel in reactor; reactor confinement; test facilities; code compliance; safety instrumentation and set points; and control criteria. Also discussed are the administrative procedures for process control, operator certificati… more

Provisional specifications for prototypical lithium-aluminum target element 05T

Description: The 04T lithium-aluminum target elements that were irradiated at Hanford during the early part of 1963 indicated that a longer element would be more desirable from the standpoint of tritium production. The Production Fuels Sections was requested in late August, 1963, to manufacture a test load of ``O`` size elements that would be five inches in length. This document presents the manufacturing information that is necessary to make a finished target element five inches in length that will approxi… more

[Delta]I = 1/2 Rule for Non-Leptonic Strangeness-Changing Decay Processes

Description: Gell-Mann and Pais were the first to suggest that the non-leptonic decay processes of strange particles may be subject to an isospin selection rule, allowing only those decay transitions which involve a change [delta]I = 1/2 in to total isopin of the system. At present, however, there is really no theoretical framework for the description of weak interactions into which this selection rule fits in a natural and compelling way. The report includes sections on the 91) decay processes of the [care… more

Two-Phase Pressure Losses Quarterly Progress Report: Seventh Quarter, August 12, 1963 - November 11, 1963

Description: Technical report describing that the pressure drop along an annular channel with dimensions D(1) = 0.375 inch; D(2) = 0.875 inch, L = 70 inches. Flow was vertical and upward, and only the internal surface was heated. Subcooled conditions existed at the inlet, with two-phase conditions at the exit. Groups of three radial spacer pins on 18-inch centers along the channel, held the inner surface concentric with the outer surface. The single phase loss coefficient for each spacer group is K(8) = 0.2… more
