Workers at the Hinkley Point C nuclear construction project in the United Kingdom have completed the 49,000-ton base for the station’s second reactor, Unit C2, hitting a target date set more than four years ago, according to EDF Energy.

The use of an easily reproducible neutron source reaction that produces a well-known continuous spectrum of neutrons over a range of energies is an ideal solution for some neutron detector efficiency calibrations. Fission chamber measurements of the 27Al(d,n) reaction have proven valuable for detector calibration for energies between 0.2 and 14 MeV. To complement the aluminum data, measurements were made with a fission chamber at 60 deg of the neutron spectrum produced from the 7.5-MeV deuteron bombardment of a thick natural boron target. This should enable accurate and efficient calibration of neutron detectors for the energy range between 0.09 and 19.6 MeV. Tenth-order polynomial fits to the data are provided for the region with energies between 88 keV and 2.33 MeV and the region with energies between 1.76 and 19.6 MeV.
