Sensor performance for BWR dosimetry experiments

In neutron dosimetry a combination of sensors (dosimeters) can be used for determining a flux density, fluence, and/or neutron spectrum in nuclear reactors. Each dosimeter is sensitive to a specific energy range, and, if desired, increased accuracy in the determination of a flux-spectrum can be achieved by the use of dosimeters that collectively embrace the significant neutron energy range. This report will briefly describe the selection, design, irradiation, post-irradiation handling, and quality control of neutron dosimeters utilized for thermal reactor surveillance neutron dosimetry at Browns Ferry Unit 3 (BF3). It will cover in-vessel, cavity, and drywell program work at BF3 through mid-1979. Photofission effects appear to be significant at pressure vessel surveillance locations
