摘要： The invention relates to a control rod for a boiling water reactor. The control rod comprises a top piece and a bottom piece between which an absorber part is arranged. The absorber part comprises a central part (4) and four absorber blades (3) extending from the central part (4). The absorber part comprises a channel (10) which comprises the central part and which extends along the length of the whole absorber part. The channel is surrounded by walls of a neutron-absorbing material with a long service life, for example hafnium. The channel is at least partially filled with a moderator, for example light water. During the manufacture the absorber part has undergone a heat treatment such that the hafnium alloy has been completely or partially transformed from alpha -phase to beta -phase and thereafter been rapidly cooled to alpha -phase.

摘要： The invention relates to a control rod insertable into a guide thimble of a nuclear fuel assembly to provide xenon compension.
The control rod (32) consists of a rod-like inner member (34) and a tubular outer member (36) each composed of alternating poison regions (38,42) and non-poison regions (40,44). The rod-like inner member (34) extends axially through the tubular outer member (36), and one of the two members is axially movable relative to the other such as to vary the degree of overlap between the respective poison and non-poison regions of the two members and thereby change the overall worth of the control rod.

摘要： The invention discloses a reactor lateral reflection layer telescoped control rod capable of separately achieving cold shutdown. The control rod comprises an inner rod, an outer rod and a guide cylinder assembly which are vertically and coaxially arranged, wherein the outer rod and the guide cylinder assembly are hollow cylindrical bodies; the top end of the inner rod can move up and down inside the outer rod and the other end of the inner rod moves up and down, along with the top end, inside a control rod passage which is positioned below the guide cylinder assembly and is coaxial with the guide cylinder assembly; and the top end of the outer rod can move up and down in the guide cylinder assembly and the other end of the outer rod moves up and down, along with the top end, inside the control rod passage. According to the reactor lateral reflection layer telescoped control rod, on the premise of not changing the height of a pressure vessel and other total design parameters of an existing modular pebble-bed high-temperature gas-cooled reactor, the effective length of the control rod can be increased to the greatest extent, reactivity value of a control rod system is improved, meanwhile, the startup and operating control operation of the modular pebble-bed high-temperature gas-cooled reactor is simplified and a technical foundation is laid for safe and economic operation of a high temperature reactor power plant.
