Wide Range Fission Chamber

Four other types of radiation detectors are the self-powered neutron detector, wide range fission chamber, flux wire, and photographic film. [Pg.75]

There are two distinct advantages of the self-powered neutron detector (a) very little instrumentation is required—only a millivoltmeter or an electrometer, and (b) the emitter material has a much greater lifetime than boron or U235 lining (used in wide range fission chambers). [Pg.76]

A description of how self-powered neutron detectors, wide range fission chambers, flux wires, and photographic film detect radiation is summarized below. [Pg.78]

The neutron flux measurement system comprises three independent measuring channels based on fission counters, a wide range fission chamber and compensated ionization chambers which are able to keep track of neutron flux for the whole operation range of the reactor. There is an overliq) between the chaimels, as well as an adequate margin over Full Power (FP) for the follow-up of eventual power excursions (see Fig. 3.1). [Pg.66]

A Fission Chamber suitable for operation in both Pulse and Campbell modes is used as the detector in the Wide Range Linear Channel. [Pg.70]
