NOVELTY - This new type utility claims one belonging to the reactor control rod of a graphene layer use a machinery device field and energy field, this utility new type change control rod a, a of the traditional Ag-In-Cd material is added some graphene material, graphite material is multi-layer graphene structure, placed in a traditional Ag-In-Cd material made of rod material outer surface, inner surface or middle part, which not only ensures a traditional control rod neutron absorbing a, but also increase the machinery intensity of reactor control rod, futher ensure the safety of nuclear power, reactor safety, valid operation, it also ensures the appearance size of a bar, would not cause structure change of whole pressure container. A rod absorption reactor neutron, regulating reactor power time in normal operation, low accident into negative. At the same time, the manufacturing and processing of whole control rod, adding graphene layer has a certain economical efficiency.
