Development of the OMRE Control-Safety Rod
- North American Aviation, Inc., Canoga Park, CA (United States). Atomics International Div.
A description of the control-safety rods for the OMRE (Organic Moderated Reactor Experiment) and the developmental testing of these rods are presented. The OMRE control-safety mechanism utilizes an electro-mechanical drive in conjunction with a rack and pinion for insertion or withdrawal of rods. The nuclear poison material consists of boron carbide powder compacted and sealed in AISI 4130 tubing. The twelve rods required are paired into six groups to reduce the number of drive units. Four groups are used for shimming action and have only a slow-speed drive. The other two groups can be used for either shimming or regulating action and have both slow-and fast-speed drives. The rods also function as safety rods by utilizing a quick-release mechanism. A prototype red was tested under reactor operating conditions. Descriptions of the drive motor and gear assemblies, rack and pinion, scram release mechanism, snubbing action, rod guidance, and a discussion of materials compatibility are presented.
