Abstract

The characteristics of a shadow cone, especially designed and constructed for use with a $D_2O$ moderated $^{252}Cf$ neutron source, have been studied. The above facility was developed for calibrating neutron dosimeters/spectrometers meant for use in the vicinity of nuclear reactors. The experimentally determined attenuation factor of the shadow cone for a source-detector distance of 67.3 cm is 63.32. MCNP calculations show that addition of 10 cm wax in between borated wax and iron plates in the present shadow cone will further reduce the transmitted neutron flux.

Özet

Özellikle $D_2O$ ile modere edilmiş $^{252}Cf$ nötron kaynağı için tasarlanmış ve inşa edlimiş gölge konisinin karakteristikleri üzerinde çalışılmıştır. Yukarıdaki tesis, nükleer reaktörlerin yakınında kullanılacak nötron dozimetreleri/spektrometrelerin kalibre edilmesi için geliştirilmiştir. Gölge konisinin deneysel olarak belirlenmiş sönüm faktörü, 67,3 cm lik kaynak-dedektör uzaklığı için 63.32 dir. NCNP hesaplamaları göstermiştir ki mevcut gölge konisindeki boronlu balmumu ile demir plakalar arasına 10 cm'lik balmumu eklenmesi iletilen nötron akısını daha fazla indirgeyecektir.
