Patent Number: 
Section: claims

1. A defective fuel bundle location system for use with a heavy water moderated nuclear fission reactor having a fueling machine, comprising: a test tool defining an internal volume, the test tool being configured to be received entirely within both the fueling machine and a corresponding fuel channel of the reactor; and a test container defining an internal volume, wherein the test container is configured to be received within the internal volume of the test tool and the internal volume of the test container is configured to receive primary fluid from the reactor when the test tool is disposed within the corresponding fuel channel of the reactor,wherein the fueling machine further comprises a ram configured to activate the test container so that primary fluid is received in the internal volume of the test container. 2. The system of claim 1, wherein the test container is configured to draw the primary fluid into the internal volume of the test container by way of the interior volume of the test container being initially at a lower pressure than a pressure of the primary fluid. 3. The system of claim 1, wherein the fueling machine comprises both an accept machine and a charge machine. 4. The system of claim 1, wherein the ram of the fueling machine is configured to both insert and withdraw the test tool from the corresponding fuel channel of the reactor. 5. The system of claim 4, wherein the test container further comprises one of a bellows and a piston configured to draw primary coolant into the internal volume of the test container. 6. A defective fuel bundle location system for use with a heavy water moderated nuclear fission reactor, comprising:a fueling machine including a charge machine with a ram;a test tool defining an internal volume, the test tool being configured to be received within both the charge machine of the fueling machine and a corresponding fuel channel of the reactor; anda test container defining an internal volume, wherein the test container is configured to be received within the internal volume of the test tool and the internal volume of the test container is configured to receive primary fluid from the reactor when the test tool is disposed within the corresponding fuel channel of the reactor,wherein the ram is configured to activate the test container so that primary fluid is received in the internal volume of the test container. 7. The system of claim 6, wherein the fueling machine further comprises an accept machine. 8. The system of claim 6, wherein the test container is configured to draw primary fluid into the internal volume of the test container by way of the interior volume of the test container being initially at a lower pressure than a pressure of the primary fluid. 9. The system of claim 6, wherein the ram of the fueling machine is configured to both insert and withdraw the test tool from the corresponding fuel channel of the reactor. 10. The system of claim 9, wherein the test container further comprises one of a bellows and a piston configured to draw primary coolant into the internal volume of the test container. 11. A defective fuel bundle location system for use with a heavy water moderated nuclear fission reactor, comprising:a test tool defining an internal volume, the test tool being configured to be received within both the fueling machine and a corresponding fuel channel of the reactor; anda test container defining an internal volume, the test container being configured to be received within the internal volume of the test tool and the internal volume of the test container is configured to receive primary fluid from the reactor when the test tool is disposed within the corresponding fuel channel of the reactor,wherein the test container further comprises one of a bellows and a piston configured to draw primary coolant into the internal volume of the test container. 12. The system of claim 11, wherein the test container is configured to draw primary fluid into the internal volume of the test container by way of the interior volume of the test container being initially at a lower pressure than a pressure of the primary fluid. 13. The system of claim 12, wherein the fueling machine further comprises a ram configured to activate the test container so that primary fluid is received in the internal volume of the test container. 14. The system of claim 13, wherein the ram of the fueling machine is configured to both insert and withdraw the test tool from the corresponding fuel channel of the reactor.
