Annual report submitted by the Boy Scouts of America to Congress describing highlights from 1966, activities, finance, membership, public relations, honors, organizational leadership, and other information about scouting programs.

The purpose of this memorandum is to describe the concepts for accomplishing localized tailoring of thermal neutron flux. The application of fuel displacement and enrichment techniques in lattice cells surrounding a test facility may accelerate sample irradiation rates by an order of magnitude or more above those in the normal reactor environment. Thus, test irradiation conditions may be established by such flux tailoring techniques which are not indicative of the specific flux and power conditions characteristic of the reactor loading as a whole.

Monthly newsletter of the High Plains Underground Water Conservation District No. 1, discussing the field of underground water. Topics include profiles of water conservation research, annual pre-plant soil moisture survey data, annual Winter Water Level measurement data, and information about the latest water conservation tips.

Neutron yields for alpha particle reactions with beryllium, boron, carbon, magnesium, and oxygen are calculated. The dependence on energy of the incoming alpha particles is analyzed for yield. Calculations are varied for different sets of cross section data.

Report on the last of three parts of an archaeological project conducted at Mission San Antonio de Valero (The Alamo) to recover architectural data, historical information, and valuable antiquities.

The diffusivities presented in the present paper are determined using the same technique and the calculated diffusivities for both TaC and Ta2C are found to be in good agreement with Resnick et. al.

For zero net wind transport conditions the doses obtained with th AI particle size distributions are not significantly different from those obtained with the BMI distribution. Small (< 20 micron) particle data are needed.

This report presents the details of the activities of Douglas United Nuclear at the Hanford site during the month of February 1967.

The objectives of the NES Duct Coolant System Water Flow Tests was to check out the Duct Coolant System under dynamic flow condition, to determine adjustments needed to achieve the prescribed flow rates in the various flow paths, and to determine its operational characteristics.

The following report presents data from the SALMON experiment, an experiment made to study the mechanics of a tamped nuclear detonation in a salt dome in terms of generated shock waves as they are propagated out of the dome and progressively through the crust and mantle of the earth. This experiment was made in the Tatum salt dome, Mississippi, October 22, 1964.

We have attempted to determine the relative biological effectiveness (RBE) of negative pions in the Bragg-peak region as compared to the plateau region and to gamma rays. We irradiated LAF{sub 1} mice, bearing 5-day-old lymphoma ascites tumors, in the peak and plateau regions of a 90-MeV pion beam for 40 hours in temperature-controlled holders. The animals were then sacrificed; lymphoma cells were withdrawn and titrated into adult female LAF{sub 1} mice. The proliferative capacity of the irradiated tumor cells was evaluated after 8 weeks by observing the percentage of animals developing ascites tumors. Surviving fractions were then calculated from LD{sub 50}`s of control and irradiated animals. Radiation doses in the 50 plateau region were measured with LiF dosimeters calibrated against cobalt-60 gamma rays. We calculated peak doses from those at the plateau, using a measured average peak-to-plateau ionization ratio of 1.5. Doses in the plateau region ranged from 145 to 250 rads; doses in the peak region ranged from 220 to 380 rads. The survival curve for cells irradiated in the peak region gave a D{sub 0} of 65 {plus_minus} 15 rads. The plateau points were not reliable. A replicate experiment was performed using Co{sup 60} {gamma}-rays, yielding a survival-curve …

Data are summarized on levels of radioactivity in environmental samples collected at Hanford during 1966, including detailed data on samples collected during December. Data are included on the radioactivity in fallout from Chinese and Russian nuclear weapons test, samples of drinking water and Columbia River water, the /sup 56/Mn content of Columbia River water sampled at various locations, the /sup 131/I content of gaseous wastes and surface waters, and the radioactivity of soil samples from the chemical separations liquid waste treatment and disposal area. The radiation dose to personnel during the year from all enviromnentl sources was estimated to be less than 0.3 percent of the applicable limits. (CH)

The ACIR Library is composed of publications that study the interactions between different levels of government. This document is a handbook for interlocal agreements and contracts.

Assembled papers regarding advances in irradiation capsule technology.

We investigated electron and gamma spectra of mixtures of isotopes of curium. This was done on a beta spectrometer with double focusing at an angle of {pi}{radical}2 and on a scintillation gamma spectrometer with a 40 {times} 40 mm NAI(Tl) single crystal detector. The observed electron spectrum are interpolated and presented. Also, experimental results of the ratio of conversion at L and M subshells are presented and compared to theoretical values.

This memorandum describes the goals for the fourth quarter of fiscal year 1967, for the Plowshare Program. The goals are set out as minimum goals to be achieved by different divisions in the laboratory which are involved in this program. Some of the direction depends upon whether a preliminary test explosion is fired.
