Control rods

So this identifies a number of thermal neutrons absorbed in control rods and water and that's sort of the thermal utilisation.

To make sure the power plant does not overheat, control rods made of a material that absorbs neutrons are lowered into the reactor.

The control rods soak up the neutrons that mediate the chain reaction which produces most of a reactor's energy, shutting it down.

9 sec The control rods , made of boron and silver, are lowered, which slows down the nuclear chain reaction within the core.

Lowering of the control rods into the reactor core slows down the rate of the reaction.

During normal operation in a BWR, the control rods are used to maintain the chain reaction at a critical state.

Within seconds after the earthquake started, the control rods had been inserted into the core and the nuclear chain reaction stopped.

The sea water was also laced with boric acid, which can soak up stray neutrons that the control rods miss.

If anything unusual occurs, the control rods immediately drop, shutting off the nuclear reaction.

In addition, the set-up included "control rods" made of a material that absorbed neutrons.

Control rods were inserted into the cores to stop fission, but cores need several days to cool down.

The seawater was also laced with boric acid, to soak up stray neutrons that the control rods missed.

Clearances for the control rods may be impaired by obstacles in the path of the rods.

The control rods are made of boron which absorbs neutrons.

On Nov. 26, 2008, Tepco reported that water oozed from the casing of two valves in the hydraulic system used in control rods.

The control rods are also used to shut the reactor down from 100% power to about 7% power (residual or decay heat).

Boron and Silver control rods are lowered into the reactor. PORV light goes out, indicating valve is closed.

Control rods shut down the nuclear fission reactions that generate power.

But the rods still produce heat, even when control rods are in place, requiring a cooling system to maintain temperatures.

GAM and THERMOS cods are used in the usual way to produce cross sections of core, reflector, and materials used in control rods, etc.

When the control rods are inserted into the core, they absorb neutrons and stop the fission chain reaction.

Control rods are used in a PWR typically to change the power level and also to shut down the reactor.

The control rods absorb the neutrons and kill the chain reaction instantaneously.

It seems the control rods aren't adequate to regain control of the fission.

To avoid a runaway reaction , the reactor includes control rods .

Many modern moderate the reaction with control rods that, when inserted into thenuclear fuel, slow down neutrons.

But control rods can fail and reactors can overheat if not properly managed.

And these reactors are typically run un-rodded, namely no control rods in the core.

This paper covers the testing results of about 200 assemblies of fuel and control rods in the reactor core.

Testing results of about 200 assemblies of fuel and control rods in the reactor core are contained.

Because the control rods are fully inserted, the Uranium chain reaction is not happening.

If something should go wrong, the control rods would drop.

In the power plant, that process is slowed down by control rods.

Now displays upgrade cameo for control rods.

In order to control the nuclear chain reaction, the reactor operators use so-called "control rods" .

Above the core, you'll see control rods.

In order to control the nuclear chain reaction, the reactor operators use control rods.

And this is done because the control rods are not in the pebble bed.

For a complete meltdown to occur, all control rods must be uncovered by cooling media;
