neutron reflector

A common material for a neutron reflector is beryllium metal.

A tamper also tends to act as a neutron reflector.

There was also a graphite neutron reflector surrounding the core.

This is a very light, stiff metal, which would form an X-ray window, and become a neutron reflector.

It's a good neutron reflector as well as the starting explosive.

When that happened, the water began to function as a highly effective moderator rather than just a neutron reflector.

The core design is annular with a centre column as a neutron reflector.

A neutron reflector is any material that reflects neutrons.

The brick acted as a neutron reflector, bringing the mass to criticality.

This in turn is surrounded by a beryllium neutron reflector with 12 rotating control drums.

The element beryllium is particularly useful due to its ability to act as a neutron reflector or lens.

Often the same layer serves both as tamper and as neutron reflector.

Because the core was surrounded by a good neutron reflector, at explosion it comprised almost 2.5 critical masses.

The design relies on a moveable neutron reflector to maintain a steady state power level for anywhere from 10 to 30 years.

The purpose of the neutron reflector was to reduce the mass required for the plutonium core to attain criticality.

It features several design enhancements including a neutron reflector, improved efficiency and improved safety systems.

The core is surrounded by a steel neutron reflector which increases reactivity and saves 0.1wt% U-235 enrichment.

The coolant does serve as a neutron reflector returning some escaping neutrons to the core.

Coincidentally, high density materials are excellent neutron reflectors.

It uses neutron reflector panels around the perimeter to maintain neutron density.

Some designs add neutron reflectors or absorbers.

U is a good neutron reflector so the position of the blanket controlled the number of neutrons available to the reaction.

Neutron reflector provided for you, free: all the water and lead and tin and solder you want.

A bare critical mass of plutonium at normal density and without additional neutron reflector material is roughly 10 kilograms.

Tungsten carbide is also an effective neutron reflector and as such was used during early investigations into nuclear chain reactions, particularly for weapons.
