नियंत्रण-छड़ इसके अंग्रेजी अर्थ का उदाहरण

SCWRs would likely have control rods inserted through the top, as is done in PWRs.

The platform has been trenched in front of the signal box, which is situated on the southwest side of the station building fronting the former ticket and parcels office, creating a pit for control rods which has been covered with timber boarding.

Picard, having taken the control rod from the trilithium's storage container during his fight with Kelsey, states that they will not get far as the trilithium explodes, destroying the shuttle.

In 1961, Engineer Thomas Purcell built a towable Rogallo-wing glider with an aluminum frame, wheels, a seat and basic control rods; soon he replaced the wheels for floats and motorized the aircraft.

Also inside the core are control rods, filled with pellets of substances like boron or [or RAF Tempsford is a former Royal Air Force station located north east of Sandy, Bedfordshire, England and south of St.

A reactor consists of an assembly of nuclear fuel (a reactor core), usually surrounded by a neutron moderator such as regular water, [water], graphite, or zirconium hydride, and fitted with mechanisms such as control rods that control the rate of the reaction.

Control rods made of a strongly neutron-absorbent material such as cadmium or boron can be inserted into the core: any neutron that happens to impact the control rod is lost from the chain reaction, reducing \alpha.

When the control rods are withdrawn and criticality is approached the number increases because the absorption of neutrons is being progressively reduced, until at criticality the chain reaction becomes self-sustaining.

The reactor will go critical at the same control rod position whether a source is loaded or not.

This has effects on how reactors are controlled: when a small amount of control rod is slid into or out of the reactor core, the power level changes at first very rapidly due to prompt subcritical multiplication and then more gradually, following the exponential growth or decay curve of the delayed critical reaction.

Furthermore, increases in reactor power can be performed at any desired rate simply by pulling out a sufficient length of control rod.

Some reactor poisons are deliberately inserted into fission reactor cores to control the reaction; boron or cadmium control rods are the best example.

Because the 135Xe absorbs neutrons strongly, starting a reactor in a high-Xe condition requires pulling the control rods out of the core much farther than normal.
