One of most important precise part of rod drives line processed, its most basic function are provided reliably for the lifting of control rod and underthrust
It is oriented to and protects, it is ensured that reactor maintains in startup, power adjusting, power and normally and under accident conditions control rod can
Quick insertion reactor core, realizes safe shutdown.
At present, the C＆P systems used both at home and abroad in commercial pressurized water reactor are essentially fasces type C＆P systems, its
Guide frame is only that C＆P systems provide necessary guide channel, and can not realize the buffering work(to the quick scram of control rod
Energy.Commercial pressurized water reactor is realized to C＆P systems scram buffering by fuel assembly, by waterpower buffering and mechanical damping
Two parts are formed.Waterpower buffering is that control rod guide pipe latter end sets one section of undergauge section in fuel assembly, in Dropping of control rod
Latter stage extrudes the cooling agent in guide pipe by control rod, a upward fluid force is produced, to Control rod drive line motion portion

When C＆P systems drop down onto upper pipe seat of fuel component, spring base is by the reaction force of upper base, the spiral bullet in spring base
Spring is compressed, so as to sponge the remaining impulsive force of C＆P systems.
Supercritical reactor C＆P systems employ cross C＆P systems, because Control rod drive line operates in height
Under conditions of temperature, high irradiation, cross control rod metal can be deformed after being irradiated, thus, cross control rod and fuel
Gap too small situations such as would potentially result in card rod between component passage, produces, therefore the cross control in supercritical reactor
Rod is difficult to realize enough waterpower bufferings by reducing the cross gap between control rod and fuel assembly.So for
Supercritical reactor, the waterpower buffering of the quick scram of Control rod drive line can not be realized by fuel assembly again.
The content of the invention
The technical problems to be solved by the invention are：Cross control rod is controlled by reducing in existing supercritical reactor
