Nuclear safety criteria for special test loads -- N-Reactor

Description: The initial fuel landing for the N-Reactor and the use of a specific alternative fuel element are described in a previous report. It is highly probable that it will also be desirable in the future to irradiate still other types of fuel elements in the reactor. If the test is of small scale, fever than five channels, or if these elements vary only slightly from the initial fuel load (or any other fuel type approved for large-scale use at some future date), the irradiation will be accomplished wi… more

Evaluation of the ``machined parts`` cask for off-site shipments of irradiated lithium

Description: The ``machined parts`` casks are shipped to Hanford by Savannah River for loading with irradiated lithium alloy slugs and returned for processing. The casks have been in service for about 10 years and have shielding material more than what is required by regulations for radiation attenuation. Evaluation shows that rupture of the shell is probable for edge or corner drop, with considerable displacement of shielding. The cask would fail in a 2-hour fire of 2000 F with loss of shielding and probab… 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

Report of invention

Description: This invention discloses a method of making a synthetic nuclear fuel by mixing pure U-233 with U-238 fuels, such as depleted uranium, to produce a fuel that combines the most desirable nuclear properties of both the U-233 and U-238 fertile material. The process requires that U-233 be manufactured in such a manner as to be relatively uncontaminated from U-232. The subject of this invention is a method of fuel handling that incorporates the desirable features of both U-233 and U-238. It is propos… more

FPT-63-27: Dimensional stability, model 1807 shape castings

Description: Due to sluggish transformation rates of metastable phases, unalloyed Pu continues to shrink after casting. Therefore, a pre-machining holding period is required to promote finished part dimensional stability. This test will determine the holding period commensurate with both this requirement for stability and an optimum material inventory level. Four storage periods will be evaluated (9, 8, 7, 6 days) for dimensional changes and related to parts stored for the standard 10-day period.

Flowsheet for americium recovery and purification

Description: Americium (atomic weight 241) grows into plutonium as a result of the 13-year half-life beta decay of Pu{sup 241}. An appreciable quantity of Am{sup 241} has.grown into the scrap that accumulated following shut-down of the Recuplex facility, and which will be processed during the initial period of operation of the plutonium reclamation facility. Current interests in trans-plutonium research and in isotopic heat sources make it desirable to consider the recovery of this Am{sup 241}. The americiu… more

Analysis of E-N target conversion data

Description: Production efficiency studies of the E-N loading require that conversion ratio values for both plutonium and tritium be defined. Changing of the core-loading charge makeup with each core load to obtain a more efficient loading has theoretically resulted in increasing the tritium conversion ratio. Tritium recovery data from the third H Reactor E-N loading has recently become available for analysis. The buildup of product is much slower in fringe blanket material then in core target pieces. The s… more

Design criteria: Bauxite-sulfuric acid feed facilities 100-K Area

Description: These criteria delineate objective, bases, and functional requirements governing preparation of design of the bauxite-sulfuric acid feed facilities installed in the 183-KE and KW Buildings. These facilities produces the chemical coagulant used in the treatment of Columbia River water in the K Area water plants and thus replaces the existing liquid alum feed systems used for this purpose.

Interim report I: Production test IP-581-A, half-plant high flocculation pH test at B Reactor

Description: A half-plant high flocculation pH test began at B Reactor on September 24, 1963. The purpose of the test was to determine whether operation of the water plant flocculation basins ad filters at a pH higher than 7.0 with subsequent coolant pH adjustment to 6.6 is beneficial as far as radioactivity in the effluent is concerned. It is planned to increase the flocculation basin pH in steps to a maximum of 7.6. Although primarily an effluent activity test, fuel discharged after a metal cycle at each … 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

Preliminary survey, Reactor formation of rhenium-tungsten alloy

Description: This document considers the costs of rhenium formation as produced by irradiating tungsten. Two isotopic compositions of tungsten are considered for the study. The cost for reactor-formed rhenium appears to be prohibitively high -- over $20 per gram. This cost would exist for tungsten containing 90% 186, 9, 184, and 1% tungsten 182 and 183. The cost of alloy made fro natural isotopic compositions of tungsten would be higher by a factor of 3, and would take prohibitively long to produce signific… 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.

Goal exposure for rupture-prone fuel element lots

Description: The loss associated with low goaling rupture-prone material is quite small compared to the benefits. There is an optimum goal exposure for a given metal quality. At this optimum exposure the loss associated with irradiating rupture-prone material is minimized. Reasonable decision rules are as follows: Discharge, at the first opportunity, tubes containing rupture-prone material whose exposures are equal to or greater than 50 percent of normal goal. Discharge tubes under 50 percent of normal goal… more

Irradiation and Performance of Depleted Uranium

Description: The production of plutonium containing 17 to 18 per cent Pu-240 has been proposed for Hanford as part of the over-all process for production of transuranium isotopes. Purpose of this report is to summarize measures that would be taken to ensure good performance of the depleted uranium fuel elements and to predict the performance of the depleted fuel.
