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.

VIDCAL is the first of three codes in the data reduction package. This code uses punch card input to calibrate and label data from BCD data tapes.

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)
