The use of aluminum sulfate for 100 Areas' process water coagulation

Description: Increases in power levels of the Hanford Piles have resulted in increased demands for process cooling water to the extent that the present filter plants are now operating at or above their design capacity. Further power level increases requiring even more cooling water may demand the operation of the filters considerably above design capacity. It has been proposed that by the use of aluminum sulfate, or filter alum, as a process water coagulant and activated silica as a coagulation aid, the pre… more

Examination of selected ruptures from the 1956 KE outbreak

Description: An outbreak of ruptures occurred in the KE Reactor during September, 1956. Radiometallurgical examination of three of these ruptures was requested by the IPD Reactor Fuels Operation. Examination of a fourth rupture which occurred in December, 1956, was later included in the original request. This report presents the results of the requested examination work.

Pita IP-22, Sup I, E-N demonstration load

Description: The purpose of this report is to permit the charging of the fourth E-N demonstration loading at H Reactor; modifications in the charge makeup and the loading pattern, designed to improve the conversion ratio and to advantageously re-shape the longitudinal flux pattern, are recommended. These gains are available through utilization of the small surplus of excess reactivity, over operating requirements, in the present (third) core.

Beam hole flux monitors

Description: The octant monitors are an improvement over the early sub-pile flux monitors, but they still do not monitor the flux in the active zone of the reactor. Chambers located within the pile active zone would give the desired information but the inpile environment is too severe to allow a reasonable life for these chambers. A beam hole monitor is suggested to provide the desired flux monitoring. The problem of reactor flux monitoring is discussed. The beam hole monitors have the advantage of providin… more

High Radiation Levels at the Discharge Faces of the Reactors

Description: Undesirably high radiation dosage rates are being encountered in the discharge areas during reactor outages. This is costly to operations in terms of burn-out time, extra work crews, and extended outages require to complete scheduled work. Significant savings in operating costs would be realized if the rear face radiation levels could be reduced during shutdowns. As a first step towards this some measurements have been made to identify and locate the major sources of this radiation. These resul… more

Scope report, discharge area remote manipulator

Description: Trends in reactor operation and maintenance have created the need for a rear face Hanford reactor manipulator which can routinely perform certain maintenance and operational functions, and which under high radiation exposure conditions can permit ruptured slug removal or other emergency type operations tb be conducted with little or no personnel radiation exposure. Because of the need for several tools, it was decided that the most desirable approach to a satisfactory manipulator program would … more

K Area Hot Test Hole Temperatures

Description: This report details a K area test with the following objectives: find the temperature range within a graphite sample carrier; find the temperature range with a solid graphite bar; find the temperature range with a test hole; determine the temperature difference between the old and new graphite sample boats; compare the temperature of a sample load and a solid bar in the same location; and find the temperature range in which the graphite samples are irradiated in all test holes. Results and conc… more

History of the project as of February 1, 1951

Description: In 1946, it was recommended, by the district engineer for the War Department, United States Engineer Office, that it was desirable to transfer all of the functions of production to Hanford, a production installation; thereby relieving the Argonne National Laboratory, a research installation, from production duties. This decision was based on the belief by Argonne National Laboratories that the principal problems of production were solved, as a result of a meeting held at Clinton Laboratories, O… more

Contraction rates of H and K reactors

Description: It was found from graphite irradiations that the changes can be described by a growth component and a contraction component, and that the contraction is a linear function of exposure, while the growth is a function of both exposure and temperature which saturated at high exposures, say 3000 MWD/a ton. A graph is included. Contraction rate is determined for KW, KE, and H piles.

Summary of information for U.K. -- Information request on gamma flux monitor

Description: Summarized herein is the available information on the subject, ``Reactor Gamma Flux Monitors.`` Apparently, a misunderstanding exists between the U.K. representatives and the related information presented by Dr. Nilson at the Argonne meeting July 24 and 25th. Dr. Nilson`s reference at the US/UK meeting was to the use of gamma-compensated neutron detection chambers at Hanford. Such chambers have been designed and used in one old reactor for a short period as a prototype for a detector for the oc… more

A method to simulate interchannel flow through fuel element junctions during laboratory tests on a C-Reactor fuel model

Description: Interchannel flow through fuel element junctions can occur in production reactor fuel columns as a result of different pressure loss patterns in the two coolant subchannels. This interchannel flow is most significant during boiling conditions because, generally, the boiling length in each subchannel is different. These different boiling lengths result in divergent pressure loss characteristics in the subchannels and cause differential pressures to exist across the fuel element junctions. These … more

Reactivity balance and associated reactor physics data, November 1964

Description: Data in this report are significant to Pile Physics calculations and are submitted by the Area Physicists at the respective reactors. Reactivity in non-uranium charges and in radial and spike enrichment is calculated either by one-group diffusion theory or by the simpler flux-squared weighting method. The former method provides a more accurate evaluation for larger enrichment inventories; the latter method is sufficient for radial enrichment of less than about 0.25 percent excess K.

Effect of horizontal control rods in total control compensation

Description: This document provides a method for calculating the compensating effects of horizontal control rods in highly shadowed cases encountered in total control administration. The two-dimensional diffusion theory computer code ``9 ANGIE`` was used to calculate the reactivity effects of the horizontal control rod geometry with respect to total control requirements at B, D, F, and DR Reactors. For total control requirements in the center section of B, D, F, and DR Reactors the horizontal control rods w… more

Development test authorization IP-154-AL sulfuric acid study

Description: The test detailed in this report is a part of a program seeking ways to reduce the amount of radioactivity in reactor effluent water. Arsenic-76 is a major contributor to the gastrointestinal, radiation dose received by downstream users of river water. Phosphorus-32 is the principal radioisotope in the flesh of whitefish caught in the vicinity of the Hanford reservation. Recent activation analyses of the commercial grade sulfuric acid used in process water treatment have indicated that this aci… more
