title: Development of a prompt gamma neutron activation analysis facility for 10B concentration measurements at RA-3: design stage.
abstract: A PGNAA facility is being developed for (10)B concentration measurements at RA-3 reactor. Its design targets detection limits better than tenths of a microgram and irradiation times on the order of minutes. Computational models were developed, which estimated thermal neutron fluxes in irradiation position to be larger than 10(9) n cm(-2) s(-1). Calculated amounts of photons and fast neutrons make necessary for filter/moderator arrangements. An irradiation device was designed and numerically tested, which is being built and is to be used for performing characterizing measurements.
