Activation of electrical machinery. Supplement 1. [Preliminary evaluation; not applicable to ground tests]

Description: The following analysis of the induced radioactivity in SNAP-50/SPUR electrical machinery having a high cobalt content is submitted. Induced radioactivity in the flight vehicle will contribute negligibly to allowable radiation levels. This is especially so due to the low neutron to gamma ratio of assumed radiation damage tolerances to semiconductors. A calculation to estimate the order of magnitude of induced radioactivity in cobalt is attached. The calculation is based on a best guess of the ne… more

Potential problems in U-233 production

Description: Interaction of {alpha} particles with elements of low atomic number leads to the emission of neutrons by the ({alpha}, n) reaction. The light element content may become one of the limiting factors in the production of U-233 acceptable for projected uses. Neutron production by the ({alpha}, n) reaction was calculated as functions of U-232 and light element contents.

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

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

Suggested startup plan with high CO{sub 2}

Description: Following the startup of 11-6-63 at 105-B, there was an operating period where graphite stringer temperatures were above allowable, and a PCA was authorized for continued operation. It is probable that the combined effects of raising the CO{sub 2} rapidly along with the fast approach to full power level caused the temperature effects. The CO{sub 2} reached 67%. As an interim step, it is suggested that startup CO{sub 2} additions be tailored to level off at 5--10% below the equilibrium level, an… more

E-N super fuel elements

Description: The current E-N demonstration program began during mid-November 1962 in the AlSi Shop. Man meetings and conferences were held prior to this time to determine various methods by which the ultimate quality of the uranium portion of an E-N load could be enhanced at the expense of the material yield, if necessary. As a result of these meetings, it was decided that a superior grade fuel element could be manufactured by raising or lowering, as the cause may be, certain limitations that were currently… more

Production of tungsten-rhenium alloys in N-reactor

Description: This report contains the feasibility and cost data for the production of tungsten-rhenium alloys from tungsten targets in the N-Reactor. The two types of target elements assumed were: (a) tungsten containing 90 a/o tungsten-186, 9 a/o tungsten-184 and 1 a/o tungsten-183 and 182, and (b) tungsten of natural isotopic composition.

A review of the philosophy and future use of the Ball-3X system in the IPD reactors

Description: Distortion of the graphite stacks of the Hanford IPD reactors due to neutron irradiation effects has grown to where major corrective or compensatory action must be taken to preserve the operability of the safety control systems and life of the reactors. For the past few years, the line has been satisfactorily held by an aggressive maintenance program and short-range solutions. However, longer range, more permanent solutions are needed and high priority is being given to studies toward these end… more

Comparative reactor flux spectra

Description: This document is explanatory in nature and is intended to clarify certain questions about reactor neutron flux spectra in various AEC production facilities. Simplified models are used to illustrate neutron ``temperature,`` spectral ``hardening,`` and the so-called ``Westcott R.``

A preliminary study of production of tungsten-rhenium alloys in N-Reactor

Description: Feasibility and cost data are supplied for the production of tungsten-rhenium alloys from tungsten targets in the N-Reactor. The two types of target elements assumed were: (a) tungsten containing 90 a/o tungsten-186, 9 a/o tungsten-184 and 1 a/o tungsten-183 and 182, and (b) tungsten of natural isotopic composition (28.4 a/o tungsten-186, 30.6 a/o tungsten-184, 14.4 a/o tungsten 183, and 26.4 tungsten-182). It is assumed that the average thermal neutron capture cross section for the tungsten-18… more

Interim report III, production test IP-560-A: Half-plant low dichromate, low pH water treatment at C Reactor

Description: A half-plant low dichromate-low pH test was started at C Reactor on March 1, 1963. The test will demonstrate whether l.0 ppm sodium dichromate provides adequate corrosion inhibition when,the reactor coolant pH is 6.6. The test monitoring will consist of ex-reactor tube examinations, in-reactor.wall thickness measurements, coupons, visual examination of fuel elements and fuel element weight loss measurements. Previous interim reports have discussed the results obtained from the visual examinatio… more

Development status and incentives for the hot die sizing process

Description: The development status and incentives for the hot the sizing process for reactor production fuels is reviewed and updated and economic justification for the process for four different case studies presented. Based on whether the end bonding step can be eliminated, payout periods of 1.2 to 1.7 years can be realized if the present AlSi process (two-shift, five-day week) is converted to hot die sizing for all reactors. For K-Reactor operation only, Payouts of 1.5 to 2.2 years can be realized by co… more

The reactivity evaluation of PITA-IP22 demonstration load, Supp. 3

Description: PITA-IP22, SUPP II has pointed out that distinct processing advantages may be realized by simplifying the E-N core by minimizing the number of different kinds of charges and the number of target slugs per charge. In an effort to experimentally verify the theoretical effects of converting to a simplified loading, a 102-tube test section, consisting of three 5.0 inch Li-Al target elements per tube was recently charged in H Reactor, under authority of the PITA supplement. The purpose of this docum… more

Analysis and evaluation of the N Reactor Zone Temperature Monitoring System

Description: This document reports the result of an engineering analysis and evaluation of the Zone Temperature Monitoring System. The main function of the system is to protect the reactor from localized increases in reactor power which would be reflected by increases in the tube outlet temperatures in the affected zones of the reactor. This function has been implemented by the installation of immersion temperature detectors on 109 representative process tubes. The signals from the detectors will be monitor… more

Corrosion of Zircaloy-2 by pH 10 LiOH in heated crevices

Description: Both the inner and outer tubes of the N-Reactor fuel elements will have self supports spot welded to the lateral heat-transfer surface of the element. A crevice a few mils thick will exist around the weld between the support tab and the cladding. Because of the heat flux through the cladding at this point and the insulating effect of the support tab, the temperature in this crevice will be higher than that on the free surface away from the support. This can result in boiling in the crevice lead… more

Physics study of Po{sup 210} production capabilities in N Reactor

Description: The production of Po{sup 210} by irradiating Bi{sup 209} has been proposed as a possible use of N Reactor. The purpose of this study was to make an estimate of the production rates for various exposure times and flux levels. The production rate was calculated for the three flux levels of: (1) 5.0 {times} 10{sup 13} neutrons/cm{sup 2}/second, which is about the average flux level expected in the N Reactor graphite moderator; (2) 6.74 {times} 10{sup 13} neutrons/cm{sup 2}/second, which is the est… more
