neutron leakage

The nuclear engineer went down to the reactor chamber to check for neutron leakage.

It can be made inherently safe as thermal expansion of the metal alloy will increase neutron leakage.

With this arrangement, most of the neutrons were generated at some distance from the reactor boundary, and reduced the neutron leakage to an acceptable level.

Sure, and listen to a lot of mumbo jumbo about roentgens, neutron leakage, and cement patches!

Geometric buckling is a measure of neutron leakage, while material buckling is a measure of neutron production minus absorption.

In a nuclear reactor, criticality is achieved when the rate of neutron production is equal to the rate of neutron losses, including both neutron absorption and neutron leakage.

Thus, in the simplest case of a bare, homogeneous, steady state nuclear reactor, the neutron leakage and neutron absorption must be equal to neutron production in order to reach criticality.
