This disclosure relates to reactor control, and more particularly to a control rod drive mechanism and a reactor control system. The control rod drive mechanism includes a lifting-lowering assembly, a mounting assembly and a release assembly. The mounting assembly is configured to mount a control rod. The lifting-lowering assembly includes a fixing component, a scissor-type lifting-lowering mechanism and a lifting-lowering component. An end of the scissor-type lifting-lowering mechanism is connected to the fixing component, and the other end is connected to the lifting-lowering component. The scissor-type lifting-lowering mechanism is configured to drive the lifting-lowering component to move close to or away from the fixing component. The release assembly is movably arranged on the lifting-lowering component, and is detachably connected to the mounting assembly. The release assembly is configured to move relative to the lifting-lowering component when power is off to release the mounting assembly.

Microporous polyolefin membrane modified by aqueous polymer of the invention is obtained by the following steps: copolymerizing 100 parts of a water-soluble polymer, 30-500 parts of a hydrophobic monomer, 0-200 parts of a hydrophilic monomer and 1-5 parts of an initiator into polymeric colloid emulsion; adding 0-100% of an inorganic filler and 20-100% of a plasticizer based on 100% solid content of the polymeric colloid emulsion to obtain slurry; and coating the slurry on one or two surfaces of the surface modified microporous polyolefin membrane and then drying. The microporous polyolefin membrane modified by aqueous polymer has thermal shutdown effect and little thermal shrinkage, and improves the main problem of shrinkage of the microporous polyolefin membrane at high temperature.
