A REVIEW OF THE DATA AND OBSERVATIONS TAKEN FOR THE PURPOSE OF LOCATING AND ESTIMATING THE SIZE OF THE HOLE IN THE CORE

PDF Version Also Available for Download.

Description

Two different measurements of the weight of D/sub 2/O required to fill the blanket to the level at which spillover into the core occurs and visual observation of this level, using a periscope, places the elevation of the hole (or crack) in the core vessel within about 1/2 in.~ of 812 ft 5 in., or approximately 1 to 1 1/2 in below the intersection of the 30 and 90 deg cones. The inherent errors involved in estimating a liquid level in the highpressure system by weighing the liquid drained to the low-pressure system and referring to a calibration of volume ... continued below

Description

Two different measurements of the weight of D/sub 2/O required to fill the blanket to the level at which spillover into the core occurs and visual observation of this level, using a periscope, places the elevation of the hole (or crack) in the core vessel within about 1/2 in.~ of 812 ft 5 in., or approximately 1 to 1 1/2 in below the intersection of the 30 and 90 deg cones. The inherent errors involved in estimating a liquid level in the highpressure system by weighing the liquid drained to the low-pressure system and referring to a calibration of volume vs. elevation are greater for the core than for the blanket. An indication of the approximate size of the hole in the core was obtained by measuring the difference in liquid levels between the core and blanket using bubbler probes, as D/sub 2/O was caused to flow at measured rates from core to blanket, or vice versa. Heads of approximately 1/8 to approximately 3/4 in. were observed for flows in the range 19 to 65 lb/min., indicating a flow area of about 1.4 square inches, assuming a sharp-edged submerged orifice.
