Analyses and correlations of HAPO rupture experience with natural uranium material

Description: One of the major factors restricting reactor power levels is the incidence of ruptured slugs. The primary purpose in studying ruptures is to determine how reactor operating variables affect rupture rates. With this knowledge reactor operating conditions may be adjusted or controlled in the manner that will optimize reactor production. In addition, knowledge of rupture rate relationships are useful in fuel element development and in overall economic studies of existing and proposed reactors and … more

Graphite radiation damage as a reactor operational problem

Description: Radiation Damage to the graphite moderator has played an important role in the history of reactor operation at Hanford. The operational problems, potential and real, which result from dimensional instability, stored energy, and gasification, as well as the solutions to these problems are discussed. The key to the graphite problems is operating temperature and its control. At present, stack expansion remains in the fringe regions of the original reactors, which coupled with the contraction of th… more

Airborne Reconnaissance Project, Ruby Range and Sweetwater Basin, Montana

Description: Abstract: A low-level airborne radioactivity survey of parts of Beaverhead and Madison Counties in southwestern Montana was undertaken from June 6 to October 14, 1955. Flying centered around the Ruby Range-Sweetwater Basin area and concentrated on the Precambrian metamorphic complex and Tertiary lake-bed sediments. No commercial uranium deposits were discovered, and no extensions were found of the few known small occurrences. Five areas of high background detected through the survey were invest… 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

Transient Thermal Stresses in Pressure Vessels - Part II: Thermal Stress Calculation

Description: This report describes the second part of an IBM 704 Computer Code to determine transient thermal stress in pressure vessels. This part computes stresses from temperature distribution determined by the first part. A brief account is given of the solution of axially symmetric thermal stresses, using harmonic stress functions. This is followed by a description of the Code and complete input and operating instructions for a number of problems: a. Transient temperature distribution due to sudden cha… more

PAR Loop Schedule Review

Description: The schedule for the installation of the PAR slurry loop experiment in the South Facility of the ORR has been reviewed and revised. The design, fabrications and Installation is approximately two weeks behind schedule at this time due to many factors; however, indications are that this time can be made up. Design is estimated to be 75% complete, fabrication 32% complete and installation 12% complete.

Blending UNH streams of different uranium enrichments

Description: The cost and feasibility of blending UNH streams of different uranium enrichments at HAPO was evaluated on a preliminary basis. Cases studied were blending 37.5% enriched UNH with depleted E metal UNH to yield a 0.947% enriched end product, and blending depleted E metal UNH with the depleted natural uranium to yield 0.7115% enriched end product. A reasonable degree of feasibility is indicated for such a blend program at HAPO.

Production Test IP-85-A -- Water shut-off during shutdown at C Reactor

Description: This document discusses the standards and testing relating to the allowable water shutoff times for reactor tubes and crossheaders are based on theoretical calculations. The resulting limits are believed to be quite conservative and to restrict operations unduly in many instances. They are restrictive because of the conductivity and resistance data on which they are based. It is the purpose of the test to obtain the experimental data necessary to determine new water shut-off curves for the reac… more

Engineering Geology Bearing on Harbor Site Selection Along the Northwest Coast of Alaska from Nome to Point Barrow

Description: From abstract: This report describes geologic and oceanographic factors relevant to the selection of a site in northwestern Alaska, at which an experimental harbor can be created by the explosion of a nuclear device. Part I describes the results of a preliminary survey of the entire coastal and offshore region between Nome and Point Barrow: Part II consists of a more detailed evaluation of the Cape Thompson-Cape Seppings area; and Part III is a theoretical consideration of the effect of the oce… more
