BWR Control Rod CR 99
Categories: General Topics
Flawless Operability. Market-Leading Service Lifetime
The CR 99 control rod incorporates an optimized design with two separate high-density boron carbide pins in each hole. During control rod operation, neutron irradiation causes boron carbide to swell as B-10 atoms are transformed to Li-7 and He-4. With reduced diameter and tapered ends, the hot isostatic-pressed two-pin design minimizes swelling-induced mechanical strain on the blade wings and improves the ability to control mechanical behavior.
