BS>A nuclear plate camera was developed at the Bulk Shielding Facility to measure the fast-neutron spectrum of the reactor. A proton-recoil type fast- neutron spectrometer was used to measure the reactor spectra as attenuated by the BeO reflector and various amounts of H/sub 2/O. Since data can be obtained much more quickly with the spectrometer, no extensive use of nuclear plates is contemplated. However, the nuclear plate method is of established reliability, and it was considered desirable to check the spectrometer at at lease one point. It was found that the total integrated flux as measured by the two method differs by approximately 11.3%, which is within the statistical accuracy of the two instruments. (auth)
