Accurate Nuclear Fuel Burnup Analyses; Eighth Quarterly Progress Report, (September - November 1963)

Description: The objective of the Accurate Nuclear Fuel Burnup Analyses program is to develop more accurate methods for burnup analysis for general use than the current method of analysis of Ca-137 or Sr-90. The program will require from three to five years of effort.

AlSi slopovers: studies, method of elimination and results

Description: During fuel element assembly, a dip-brazing process., the aluminum can which is ultimately a jacket for a uranium core is protected from the molten AlSi solution by a steel sleeve. Once the can is inserted into the sleeve and thermal expansion is complete, upset metal rings prevent molten AlSi from flowing between the can and sleeve, a situation that warrants rejection. Passage of molten solution beyond upset metal to a point on the can wall not removed during the subsequent facing operation is… more

Application of the Variational Method to the Calculation of the Time Dependence of the Neutron Flux in Small Pulsed Slabs, Cylinders and Spheres

Description: The variational method is applied to the monoenergetic time dependent transport equation to obtain a simple relation for the asymptotic decay constant in small pulsed assemblies. The results indicate that flat trial functions may be a reasonable representation of the flux distributions in the thin slab limit. This approach is superior to many of the usual transport approximations.

Campaign rework of Z-Plant material at Purex

Description: The Purex Plant has been requested to process Z-Plant MR and EPT solutions containing about 200 kilograms of plutonium in order to alleviate processing problem at Z-Plant and to reduce the inventory of MR and EPT rework. Campaign recycle of uranium through the main plant is recommended as an economical and effective means of reworking large quantities of Z-Plant plutonium solutions. This memorandum outlines process alternates and costs for reworking the solutions and itemizes specific recommend… more

The Class of Shocks With Uniform Pressure

Description: If a piston with constant velocity moves into a shock tube containing material at rest and at uniform density, the result is well known and trivial. The shock propagates with uniform speed, the state and speed of the material behind the shock is constant. One can ask if similar flows exist for cylindrical of spherical symmetry. Quickly one rules out the possibility of a solution which retains all the properties of this trivial solution. One asks if there are any solutions such that the material… more

Control Actuator Component Test 14/W001 Torquemotor Test

Description: A permanent magnet torquemotor is used to covert the conditioned error signal from the actuator amplifier into a force capable of driving a servo-valve. In order for the results to be comparable to actuator conditions, the effort was made to duplicate the actual driving (input) and loading (output) parameters. The results of this screening test showed performance which was good, but left some doubt as to the exact nature of the 10 to 20% variation seen in both static and dynamic characteristics… more

CP -- nuclear materials transfer measurement statistics

Description: It is the purpose of this document to provide, in one well-referenced manual, a measure of the degree of reliability that may be placed on routine nuclear material transfer measurements within the Chemical Processing Department, and the relative effects of each measurement uncertainty on the various nuclear material balances. Although statistical techniques were used as a tool in analyzing the data, the results have been presented in a form that should require a bare minimum of statistical trai… more

Data Procurement and Processing for the Fission Product Inhalation Program Using an Automatic Read Out Counting System

Description: Report describing the materials and procedures used to obtain data necessary "for correlation with the biological effects of inhaled mixed fission products" -page 1. The study is primarily focused on the biological effects of radioactive materials inhaled by animals and the materials taken from these animals and tested with computers.

[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

Determination of the Nucleon-Nucleon Elastic Scattering Matrix : I. Phase Shift Analysis of Experiments Near 140 MEV

Description: A phase shift analysis is an attempt to translate experimental measurements (observables) into well-determined scattering amplitudes, since these are the quantities that can be readily compared with theoretical predictions, In this sense, the phase shift analysis should contain as little theory as possible. The scattering amplitudes (or phase shifts) constitute an experimental statement, and the phase shift analysis should logically be done by the experimental groups who measure the observables. more

Development of a Brazing Process for Seal Blocks

Description: This report covers the development and qualifications of a brazing process capable of forming the bond between the instrument leads and the seal block. The process developed is unusal in that it permits the formation of a bond between austenitic stainless steel surfaces at the temperatures below 1350°F without a flux.

Doppler Broadening of the Total, Fission, Capture, and Scattering Neutron Cross Sections of Pu-241

Description: ABS>The cross sections were calculated by the Reich-Moore multilevel formula from 0.02 to 11 ev and were convoluted with Doppler functions corresponding to various sample temperatures. The cross sections are tabulated vs neutron energy for temperatures of 27, 500, 1000, 2000, and 3000 deg C. (D.C.W.)
