Device for measuring the neutron flux distribution in the core of atom core reactors

摘要

An apparatus for measuring the neutron flux in the active region of a nuclear reactor has a plurality of individual neutron absorbing probes insertable into the active region of the reactor. One of the probes extends over the entire length of the active region and the remainder of the probes extend over progressively shorter lengths respectively of the active region. The probes have respective portions outside of the active region and a cable connection means is connected to these portions.
