Abstract
Abstract An elongated slide valve for detecting fuel leaks in a nuclear reactor has a plurality of sampling ports along one side of a valve body and a plurality of intermittently spaced flush ports along an opposing side of the valve body. A slide member alternately communicates with sampling port and flushing port as it sequentially samples the various fuel subassemblies of the reactor through the sampling ports. A single outlet chamber and throughgoing conduit exits each sample from the nuclear reactor to monitoring equipment. The reactor coolant is employed as the flush between samples and as the seal for the slide member. The slide valve is operated by the control rod drive mechanism.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
181 words
A sampling slide valve device comprising: A. an elongated valve body having a plurality of equally spaced sampling ports along a fIrst end portion of one side of the valve body and a plurality of equally spaced flush ports on an opposing side of the valve body along the first end portion, a flushing port being positioned between each adjacent sampling port; B. a movable slide member freely positioned in the valve body and having an enlarged sampling head with a sampling duct therein communicating with a central duct in the slide member, said sampling duct adapted to alternately communicate individually with each of said sampling and flush ports, respectively, said head being dimensioned to form a slight gap between the head and the valve body and to extend between adjacent flush ports when the sampling duct is in communication with a sampling port; C. an outlet chamber formed between the slide member and an end portion of the valve body opposite the first end portion, said central duct communicating therewith; and D. an outlet orifice communicating with the outlet chamber.
Claim 2
Dependent Claim
181 words
A sampling slide valve device comprising: A. an elongated valve body having a plurality of equally spaced sampling ports along a fIrst end portion of one side of the valve body and a plurality of equally spaced flush ports on an opposing side of the valve body along the first end portion, a flushing port being positioned between each adjacent sampling port; B. a movable slide member freely positioned in the valve body and having an enlarged sampling head with a sampling duct therein communicating with a central duct in the slide member, said sampling duct adapted to alternately communicate individually with each of said sampling and flush ports, respectively, said head being dimensioned to form a slight gap between the head and the valve body and to extend between adjacent flush ports when the sampling duct is in communication with a sampling port; C. an outlet chamber formed between the slide member and an end portion of the valve body opposite the first end portion, said central duct communicating therewith; and D. an outlet orifice communicating with the outlet chamber.
Claim 3
Dependent Claim
