The purpose of this test is to provide a set of experimental data to test a compute code frequently used in nuclear safety analyses and to explore certain experimental techniques which may prove extremely valuable in the future. In addition, some basic physics parameters which will be measured may be used in an assessment of the feasibility of using a deactivated Hanford reactor for space-dependent transient tests.

This report provides Source and Special Nuclear Material composition of Ending Inventory Reports for the month of January, 1967.

In this fourth semiannual issue, the reactor and power data from the Hanford Production Reactors are shown for the six-month period January through June, 1967, together with data for the three preceding six-month periods. For comparison purposes, the two years of experience will continue to be shown by dropping and adding a six- month period with each semiannual issue.

Effective use of known experimental design principles in planning nuclear-radiation-effects experiments associated with engineering development programs assures that necessary, useful information will be obtained from the characteristically costly and the time consuming radiation-effects tests. This report discusses the principles of experimental design and illustrates their compatibility with nuclear-radiation-effects experimentation by presenting a model experimental design for a hypothetical nuclear-radiation-effects experiment.

Declassifled 28 Nov 1973. The S10FS-3 Reactor was disassembled and examined. The core was removed from the core vessel and all 37 fuel elements were subjected to a nondestructive screening examination followed by a detailed examination of selected elements. The screening examination consisted of visual inspection, dimensional measurement, eddy current scanning for hydrogen distribution, and gamma scanning. The subsequent detaiIed examination of selected elements included fission gas measurement, determination of hydrogen permeation rate, inspection of disassembled fuel elements, dimensional measurement of fuel, fuel density determination, hydrogen analysis, and fuel and cladding metallography. No defects or unexpected results were observed, and the examination firmly supported the conclusion that all the fuel elements completed the reactor operation in good condition. (auth)

This document summarizes the amounts of radioactive contamination discharged to ground from chemical separations and laboratory facilities through December, 1966. Detailed data for individual disposal sites are presented on a month-to-month basis for the period of January through December, 1966. Previous publications of this series are listed in the bibliography and may be referred to for specific information on measurements and radioactivity totals prior to January, 1966. Several changes in crib nomenclature were made during 1965. These changes are noted on the individual tables so reference may be made to them in previous reports.

Program effort was redirected toward more component studies and less assembly of full modules. This principal increases of component effort was in the thermoelement assembly area where studies of alternate bonds and barrier layers were instituted. Effort in the beryllia ceramic area was increased to provide a higher quality product. Test and evaluation was continued on the flexible connector and on the hot and cold heat exchanger plates with satisfactory results.
