DEFINITION

Classification: 376/173

Having internal fertile regions:

(under subclass 172) Subject matter wherein components containing fertile material are positioned inside the reactor core proper.

(1) Note. Since it is normal for most fissile fuel components to include fertile materials along with the fissile materials and still be classified as fissile fuel components, for a patent to be placed in this subclass as an original, there must be such a preponderance of fertile material present that the component itself is classified as a fertile fuel component.
