Abstract

Disclosed is a linear motion device and more specifically a control rod drive mechanism (CRDM) for inserting and withdrawing control rods into a reactor core. The CRDM and method disclosed is capable of independently and sequentially positioning two sets of control rods with a single motor stator and rotor. The CRDM disclosed can control more than one control rod lead screw without incurring a substantial increase in the size of the mechanism.

Monitor circuit for a control rod drive mechanism

Patent Abbott, R L

A monitor circuit for a control rod drive mechanism (crdm) that is adapted to detect erroneous stator phase sequences and generate a visible and audible alarm. The monitor circuit has particular application for use in connection with the control element assembly of a nuclear reactor. The monitor circuit includes an interface circuit for each stator phase winding of the drive motor, a plurality of logic gates to detect the predetermined erroneous phase sequences, a plurality of flipflops to maintain the fault condition signal, visible and audible alarm circuits, and circuitry for resetting the monitor circuit after a fault condition.

Anticipated transients without scram program: common mode failure analysis of control rod drive mechanism

Technical Report Hammond, C W ; Oelkers, E ; Penland, J R ; ...

As part of the Anticipated Transient Without Scram (ATWS) program, Diamond Power Specialty Corporation's control rod drive mechanism (CRDM) was evaluated to determine its susceptibility to common mode failure. This study qualitatively evaluates the credibility of mechanical failure of a significant number of control rods to insert into the reactor core by trip on loss of power to the CRDM stators or to achieve powered insertion if power is available to the stators. The analytical procedure is a modification of the ''Extended Qualitative Analysis,'' Section 4.5 of IEEE Std 352-1972, 1974 Revision, ''General Principles for Reliability Analysis of Nuclear Powermore »« less
Long-term stability of Sm{sub 2}Co{sub 17}-type magnets for control rod drive mechanism (CRDM) in a nuclear reactor

Journal Article Iida, H ; Imayoshi, S ; Morimoto, K ; ... - IEEE Transactions on Magnetics

Control rod drive mechanism (CRDM) is an apparatus that regulates vertical position of control rods in a nuclear reactor by using a driving motor of synchronous type. While CRDM is usually placed outside the reactor vessel to escape from the severe environment inside the vessel, built-in type CRDM, which is now being developed for advanced marine reactors, is placed inside the vessel for making the reactor compact. The driving motor must stand in high-temperature (573--603 K) and high-pressure (approximately 120 atm) water which contains a trace amount of hydrogen. Although the magnet rotor is sealed by corrosion-resistant alloy, the magnetsmore »« less
